how to fix S8 battery drain issue

What to do if your Galaxy S8 Plus has battery drain issue following an update

Poor battery performance (battery drain issue) is often a common issue that we encounter after each and every major Android release. Even on newer devices like the #GalaxyS8 and #GalaxyS8Plus, battery drain issue is something that occurs in a regular basis. To continually remind our community that this issue is not an issue with new Android version entirely, we bring you again this troubleshooting post.

Before we proceed, we want to remind you that if you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Problem #1: What to do if your Galaxy S8 Plus has battery drain issue following an update

Hi there! I’ve been having significant battery drain problems since the last device software update arrived. I’ve tried following advice from your site and elsewhere (i.e. clearing the cache, disabling Bixby, checking screen settings, etc.) and nothing has worked to resolve it. I’ve seen other reports of similar problems on the Galaxy S8 and S8 Plus but I’d rather not factory reset my device and have to re-establish everything. I wondered if this is a wide-spread issue that a fix is coming for or is there any way to roll-back to the previous software version? I’m not getting more than about 3-4 hours of battery life out of my  device despite not doing much with it. The Battery Usage monitor is showing that it’s the “Android System” and “com.android.systemui” that’s using the majority of battery life. Any help that you can provide would be greatly appreciated! This is very frustrating! Thanks! — Mark Mmorell

Solution: Hi Mark. When it comes to battery drain issue, there’s a lot of possible reasons for it so there’s no one-size fits all solution that we can provide. If battery usage on your Galaxy S8 Plus has spiked drastically following an update, that doesn’t necessarily mean there’s coding issue involved. In most cases, non-system apps are to blame as well.

If you’ve already tried the generic solutions to reduce battery usage such as lowering screen brightness, clearing the cache partition, etc, you should continue to do the rest of troubleshooting steps that we recommend in this case. We can only guess what stuff you did already so we’ll provide the most likely helpful ones below. Feel free to skip the ones you have already tried.

Install app updates

When dealing with battery drain issue, not  a lot of users realize that lack of app updates can actually help. That’s because there’s often immediate positive result by doing it. The thing, this might very well be the solution for some app-specific battery drain issues. When updating Android, apps are not automatically updated causing potential incompatibility issues. Because new OS updates bring new features and configurations, older, outdated apps may no longer work efficiently causing a drag in terms of performance, which can then result to general system inefficiency. To minimize the chance of bugs and power drain issues after a system update, you want to also ensure that all your apps are compatible with the latest Android version you installed. Make sure to go to your Google Play Store app and update all apps from there. If you have apps from third party sources (not from the Play Store), it’s your responsibility to keep them updated.

Reset app preferences

This potential solution works with the first one in ensuring that all your apps are working as seamlessly as possible. New operating system updates may change app preferences or configurations so it’s possible that bugs can develop from apps with incorrect setup. To eliminate the chance of this issue from developing, make sure that you reset all app preferences to their defaults. By resetting app preferences, you’ll also be enabling back apps and services that may have somehow got disabled but remains important for the system to work properly.

To reset app preferences on your S8:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap More settings at the upper right (three-dot icon).
  4. Tap Reset app preferences.
  5. Restart your device and check for the bug.

Check notorious battery hog apps

This is an ever present recommendation when it comes to fixing battery power loss. More often than not, third party apps with power hogging tendencies are the main cause. Although you mentioned that the top battery hogging apps so far appears to be core Android apps and services, that doesn’t mean you’ll not address perennial apps known to be overly demanding. Social networking apps, games with online services, and apps that regularly need updates tend to be some of the common culprits. You should know that under Battery Usage menu. If possible, try to disable them for a few days and see their absence will have an impact to your phone’s overall power consumption rate.

Reset all settings

Before you commit on wiping the phone with a factory reset, you should consider resetting all settings on your device. Some Android users were able to successfully minimize the impact of battery drain issue on their device by doing it. Here’s how it’s done:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Reset settings.
  5. Tap RESET SETTINGS button to confirm.
  6. Restart your S9 and check for the problem.

Factory reset

You’ll most probably need to do a factory reset in this situation so don’t hesitate if nothing comes out positive after doing all the suggestions above. Factory reset can fix all kinds of Android ills.

To factory reset your S8:

  1. Make a backup of your personal data.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Uninstall unused apps

If factory reset won’t resolve the issue at all, that’s probably because the cause of the problem is due to an inefficient app. To minimize the chance of apps from draining the battery faster, make sure to go over all of them and remove those you don’t use or need. The more apps you install, the higher the chance of some background services constantly running in the background. Even when you’re not opening or actively using an app, a background service for it may be running 24/7. If you have a number of such apps installed, they can take a significant toll on battery performance.

After a factory reset, make sure to uninstall apps that usually requires constant or near-constant communication with remote servers. Such apps commonly includes social networking apps (Facebook, Instagram and Twitter are notorious in this sense), games (those with online services), email apps, messaging apps. In other words, you want to get rid of possible battery hogs if possible so you’ll know how the battery performs without them. If you can’t live without such apps, try to go under their settings and see if there’s a way for you prevent them from updating constantly.

Workaround: Use Power saving mode

When you think you need your phone for longer in a particular day, you can always extend battery performance by using Power Saving Mode. This is a Samsung Galaxy S feature that forces the device to run slower in terms of CPU clock speed, lower its screen brightness, use lower screen resolution, turning off Background network usage, and shutting down Always On Display. There are two options that you choose from and depending on your need, you can either pick MID or MAX.

To use Power Saving Mode:

  1. Open Settings app.
  2. Tap Device maintenance.
  3. Tap Battery.
  4. Select MID or MAX.

Unroot (optional)

If you have a rooted Galaxy S8 Plus, try unrooting it by doing a master reset (steps provided above) and see what happens. Some rooting software may not work efficiently with newer Android versions so try to see how your device works when it’s running stock firmware and without root.

Problem #2: Galaxy S8 Plus battery drops quickly and charges very fast, screen turns black when opening apps

My Samsung S8 Plus is a year old and it’s been about a month that my phone’s battery percentage drops VERY quickly. Drops 1% every 2-3 minutes. Also, charges extremely fast. When it comes down to around 60 something to 70 something percent, the screen turns black but I can still tell the phone is on because I can hear when I increase the volume.

Also turns black when I open certain apps like snapchat, screen turns black. Sometimes the phone will shut itself completely off and when i turn it back on it says it’s at 0% from 60 -80%. It does have what it seems to be a minor crack on the top left corner of the screen but it was there long before this issue started happening. (Idk if the crack might have anything to do with it).

I am currently trying the Safe Mode method and the battery still went from 69% – 60% in about 10 minutes but so far the screen hasnt turned black. — RAQUEL

Solution: Hi Raquel. It’s possble that your device’s battery just needs calibration so try to do that first. Here are the steps to do that:

  1. Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.
  2. Charge the phone until it reaches 100%. Be sure to use original charging equipment for your device and let it charge up completely. Do not unplug your device for at least two more hours and also don’t use it while charging.
  3. After the elapsed time, unplug your device.
  4. Perform a warm restart by holding the Power and Bixby buttons simultaneously until the startup logo appears.
  5. Use your phone until it completely runs out of power again.
  6. Repeat steps 1-5.

Should the issues remain after you calibrate the battery and OS, do a master reset (factory reset) and see if that will fix them. If nothing changes after a factory reset, that means that the issue is most likely not within your ability to fix. In this case, you want to get professional support from Samsung.

How to fix Galaxy S8 Plus with poor battery life [troubleshooting guide]

Like it or not, poor battery life is an expected issue for even top-of-the-line phones like the #GalaxyS8 and #GalaxyS8Plus. Needless to say, this is a common problem ever since the first smartphone was released so it’s no surprise that a lot of S8 Plus users are reporting the problem.
In this troubleshooting episode, we include three reports from some members of our community who reached out to us and our suggestions on how to go about this issue.

Here are the three cases:

Ever since the software update my phone’s battery is draining really fast, it used to give me 24 hours of battery time which is now reduced to less than 15 hours. My phone is the same as it was 2 days ago. — Ehsan 

My Samsung Note 4 Battery drains so fast after its been 100% charged Also the phone gets hot while in use. What could be responsible. — Solaomisore1

Thank you for taking my question.  Well it’s simple, my wife’s galaxy S8 Plus battery drains at a rate 5 times faster than my galaxy and we are trying to figure out why.  These phones both have been recently reset to factory standards However, for what ever reason my wife’s phone will go from 100% to 15% in about 3-4 hours with minimal use (no phone calls or streaming anything).  

I check all of her installed applications and they do not differ with my apps. (as a matter of fact I have more apps installed then she does – yet my phone works all day.  Anyway, if you have any insight as to what may be causing this. Sadly I have to put my wife phone in ultra low power mode just to get her thru the day, and that should not be a solution.  So…any insight as to what factory apps or installed apps could be causing this? Or another switched on function that I may not know about, as when you factory reset the device, there are many questions (Allows and Deny) that you have to answer.   

Like I said, both phone have all the factory apps installed and your basic, Facebook, Twitter, Instagram, Messenger, and Flashlight apps added.  Just can’t figure out what could cause such a drain on her phone that is not occurring on mine. Any insight…would be greatly appreciated. Thanks. –David 

Solution: For these three users, there seems to be clear reason why their S8 Plus’ battery has poor life. While one (Ehsan) has mentioned that the issue appeared after installing an update, this problem can actually happen with or without an update installation. When it comes to the question of what may be causing a phone’s battery to empty faster than usual, the answer is often not straightforward. There can be many different reasons as each device is unique in its own way. Every user has his or her own usage habits as well so it’s not easy to pinpoint where the exact cause for a particular case lies.  There are many factors to consider when dealing with battery drain or poor battery life on the Galaxy S8 Plus so we’re better off dealing with as many of them as possible. We’ll provide workarounds and solutions below and we’ll all label them as solution options. Fixing poor battery life is a hit-and-miss endeavor and sometimes, it may take a combination of steps to effectively handle it.

Solution #1: Restart your S8 Plus regularly

Bugs sometimes occur when a system has run for some time. To minimize bugs or software glitches, make sure that you reboot your phone at least once a week. This is a not a guaranteed fix for the specific issue we’re dealing right now but it’s a good first step to the right direction. If you haven’t yet, we suggest that you perform a soft restart instead of the usual restart to also clear the memory. Here’s how:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Note: Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Also, allow up to 90 seconds for the reset to complete.

Solution #2: Clear cache partition

Wiping the cache partition aims to refresh the system cache. This cache is used by Android to perform tasks efficiently, particularly when it comes to loading or running of apps. The more the operating system works efficiently, the lesser the pressure on the entire system, which in turn can be beneficial for the battery day in and day out. To clear your Galaxy S8 Plus cache partition:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight “wipe data / factory reset.”
  5. Press Power button to select.
  6. Press the Volume down key to highlight “wipe cache partition.”
  7. Press the Power key to select.
  8. Press the Volume down key to highlight “yes” and press the Power key to select.
  9. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  10. Press the Power key to restart the device.

Solution #3: Lower screen brightness

If you haven’t known it yet, that bright, amazingly colorful screen on your S8 Plus is the biggest drain on your battery. If you constantly turn it on on full brightness, don’t expect the battery to last longer every day. The super packed pixels on that 6.2-inch screen demands a lot of computing power from both the processor and the graphics chip, which in turn, needs a lot of energy from the battery. Dimming the screen to 60% or even below 50% may give a lot of extra juice for the day. This is especially relevant if you use your phone often. Of course, we don’t want to tell you that this should now be the case from hereon. You can always revert to 100% brightness if you want but if you think you need stretch the usage of your S8 Plus for a few more hours in a day, this workaround might just be what you need.

Try to lower screen brightness to the lowest comfortable setting setting every day and you’ll see the result. In the long run, this will also help extend battery life because it will also decrease the amount of charge cycles on the battery everyday.

Solution #4: Check battery usage and address possible app issue

Aside from the screen being one of the biggest contributor to fast battery drain issue, apps can also be a culprit. A lot of apps nowadays have an online component, which means that they may employ services that constantly run in the background to receive updates and data even when you’re not actively using them. For example, Facebook app regularly needs updates for its News Feeds so it constantly runs so that it can communicate with remote servers and download new contents. The same general design has become the trend for even the simplest of apps so the more apps you install, the higher the possibility that there are multiple of them constantly hogging resources even when you’re asleep. To check what these apps are, you can go under Settings > Device maintenance > Battery > Battery usage.  Under Battery usage screen, you should be able to see a list of apps that consume a lot of battery power for a certain period. From there, you can decide which apps to uninstall or modify its behavior so it no longer receives updates in real-time basis, if there’s an option for you to do so. So, for example, instead of allowing your email app to constantly communicate with email servers for new messages, you can set it to only download new emails when you manually tell it to. Other apps may not have the option to allow users to stop them from communicating with remote servers all the time so the best thing to do is to either disable them, or remove them entirely from the system. If you have apps in the list that you don’t recognize or remember that you install, they may be components of a malware attack, which is another reason why battery drain issue often occurs.

In general, use the battery usage list to know what to do next. Every user has its own needs so just try to be smart with your app usage and hopefully that will help.

Solution #5: Uninstall apps

As mentioned, apps is one of the main reasons why battery drain issue occurs. Many Android users install apps on impulse and forget about them days later. With its 128GB internal storage, that can mean a lot of apps just idling by while all the time hogging resources. Most games nowadays are like social media apps by design and they can drain the battery real bad if left installed for a long time.

No app is perfect so somewhere along the line, one of them may interfere with Android or cause coding-related bugs that can slow down the system. The more inefficient Android becomes, the more drain to the battery. This situation can easily get worse if you have multiple installed apps causing problems. To minimize the chances of apps causing the battery drain issue you’re experiencing, don’t hesitate to uninstall those you don’t need at all. Start with those apps that constantly refreshes its contents like social media apps or shopping apps. Facebook is one of the top reasons for battery drain issue across all mobile platforms but other social media apps out there can be just as problematic. Determine what apps to leave according to their use and get rid of those you only occasionally use. Or you can find better substitutes that may not be as problematic. Read app reviews and know what others are saying about the app. In general, stay away from apps that require near-constant internet connection to work.

Solution #6: Turn off AOD

While Always On Display has its use, we don’t recommend that you use it for similar reason as Solution #3. AOD can significantly drain the battery at a steady rate since the screen wil always be on. To turn it off, you can go under Settings > Display > Always On Display.

Solution #7: Turn off automatic uploads for apps or backups

Leaving your S8 Plus to upload photos, videos, backups, etc. on its own may be convenient but it can also be the cause why your phone may be losing power fast. We can’t be specific on what you need to do here since every user has its own way of setting their apps up. Try to go over your apps and review each of their settings to know if any of them is set to automatically upload something.

If you use Samsung Cloud services, try to configure it so that its components won’t upload files automatically. If you have thousands of photos in your Gallery app and you set Gallery under Samsung Cloud to ON, the upload may take a long time to finish, resulting to battery drain. The same scenario can occur with any other cloud services or apps.

Solution #8: Check for rogue apps

Bad or malicious apps can lead to all sorts of issues. Apps of this type also tend to use a lot of resources when running in the background so again, our advice above applies here as well. Again, take a deep look at the apps you have and screen each of them properly. A good rule of thumb for you here is to uninstall apps that you don’t recognize. Some apps are initially legitimate but after some time, they can turn malicious and allow malware to invade your phone. Because there’s a constant cat and mouse battle between security software and malicious developers, installing an antivirus app won’t always catch bad apps all the time. If you want to take phone security seriously, you should start by ensuring that you only install apps from reputable developers. Keep in mind that there’s no such thing as free apps. Creating an app is costly and developers usually recoup the expense they’ve spent on their products by using malicious tactics. Some may steal your personal data and sell them to other parties while others are there to do specific tasks, like force your phone to mine virtual currency without a user’s knowledge. In almost all cases, these unauthorized or malicious activities keep your phone busy all the time. Infected devices usually lags significantly and drains battery faster than expected.

Solution #9: Ensure apps and Android are up-to-date

Some bugs can only be fixed by installing a fix that comes in the form of patches. This is true for both Android operating system and apps so make sure everything is updated all the time.

Solution #10: Use Power Saving Mode

This is not a solutions but a workaround. Power Saving Mode is a useful feature that you can use if you need to stretch usage time from time to time. PSM basically transforms your phone into its dumb version by only allowing basic functions and slowing down the device. Good for days when the next charging session is hours away.

Solution #11: Factory reset

We only recommend factory reset if you’ve already exhausted all possible software solutions and workarounds. It mainly addresses the software side of a battery drain issue. In most cases, a reset is very helpful in fixing this type of problem so don’t hesitate to do it if nothing works so far. Here’s how to do it:

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight “wipe data / factory reset.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, “Reboot system now” is highlighted.
  10. Press the Power key to restart the device.

Solution #12: Get professional help

If battery drain still happens even after a factory reset, there must be a hardware issue behind. Make sure that you contact Samsung so they can help you with it.

What to do if Galaxy S8 fast wireless charging no longer works after an update

Our troubleshooting article for today covers an emerging issue about some #GalaxyS8 devices having problems with fast charging. Like any other power- or boot-related issues, the solutions in this post are the same ones we always recommend. As far as software troubleshooting is concerned, Android users are limited to the ones we provide below.

Before we proceed, we want to remind you that if you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start.

Problem #1: What to do if Galaxy S8 fast wireless charging no longer works after an update

Hello. When i plug in my Samsung “Fast Charge” wireless charger, i get a blue, then green, then blue blink on the indicator, then nothing. This is all with NO PHONE on the charger.  The charger used to work, now it does not. Nothing with my phone has changed (case, etc), but i did notice this after my latest system update. I am not very computer savvy, so if you ask a follow-up, i will do my best to help. btw, the phone is about 6 months old and was purchased brand new from Verizon. Thank you for your time and any help you can give to me. — Laurence. Laurence D Mason

Solution: Hi Laurence. It’s normal for Samsung fast charging pad to show blue, green, and another blue light when you first boot it up. If this LED light switching occurs all the time and even when there’s no phone being charged, that can be sign of something amiss. Since you did not mention it, we’ll just ask straight from you: does the fast wireless charger still charges your phone normally? If it does, then simply ignore the LED behavior. At this point, we are not sure if there’s an on-going issues with S8 devices causing wireless chargers to behave erratically or not. We checked at least 2 S8 wireless chargers and both of them are working just fine. What’s happening is probably isolated to your device.

If your wireless charger no longer works (won’t charge your S8) at this time, then you should do some troubleshooting steps to see where the issue lies. If you’re positive that the charger was fine before you installed an update to your phone, there may be a software issue with your S8 and not necessarily the charger itself. Obviously, your wireless charger can’t be updated so any glitch affecting it must be coming externally, in this situation, your S8. Unless your wireless charger has a hardware problem, all troubleshooting must be focused on your phone. Below are the things that you need to do to address the issue.

Use another official Galaxy S8 wireless charger

Although we already think that the problem must be outside of the wireless charger itself, you still need to confirm it yourself. And there’s no better way to do that than by using another known working wireless charger. We know there are many good after market chargers out there but we highly recommend that you limit yourself to official Samsung wireless chargers. Keep in mind that when we say wireless charger, we’re referring not just to the wireless pad but also to the USB cable and adapter. If you can’t secure another wireless charger, try to visit a Samsung store and see if they can let you borrow an official charger for an S8. Because you’re having an issue with a Samsung wireless charger, make sure that you only test another official wireless charging for troubleshooting purposes.

If your S8 charges fine using a second wireless charger, that means that you have a bad wireless charger. You need to replace it if you want to resolve the issue.

On the other hand, if your S8 remains problematic when charging using the second charger, there must be a problem within the phone itself. Make sure to follow our advice below.

Clear the cache partition

One of the common reasons why bugs develop after installing an update is a corrupted system cache. This is usually true if this cache gets corrupted after an update. To check if your S8 has a corrupted system cache, you need to clear the cache partition, where the system cache is stored. Here’s how to do it:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key to highlight “wipe cache partition.”
  5. Press the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.
  9. Wirelessly charge your S8 and check for the problem.

Charge on Safe Mode

Should nothing change after wiping your S8’s cache partition, the next good thing that you can do is charge your phone when it’s on safe mode. The aim of this troubleshooting step is to check for possible third party app that may be interfering with Android operating system. Also known as diagnostic mode, safe mode, blocks all third party apps from running on your S8 so if your device charges wirelessly fine, that’s a clear sign that one of your apps is to blame.

To run your S8 to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen appearing on the screen.
  3. When SAMSUNG appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. When Safe mode appears in the bottom left corner of the screen, release the Volume down key.
  7. Allow your phone to run for a few minutes and check for the problem.

If you think that there’s an app issue, you can try to identify it by following these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your J3 is still problematic, repeat steps 1-4.

Factory reset

Ultimately, you need to wipe your phone by doing a factory reset should nothing ever work. This is the only way to fix whatever software bug is causing this charging problem of yours. Since you’ve already established the fact that your wireless charger is working at this point, then there must be something in your phone that prevents it from charging wirelessly. With a newly factory reset device, you can be sure that all software settings are refreshed. We know for a fact that this problem is not there when all software settings are in their factory defaults so this is the best way to know if your S8 has a software problem or not.

To factory reset your S8:

  1. Make a backup of your personal data.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Get Samsung support

If the problem stays even after you factory reset your S8, it means that a hardware malfunction is most probably behind the trouble. If wireless charging function is important for you, you should consult Samsung for a solution. They’ll most likely end up asking you to submit your device for examination and repair.

Problem #2: Galaxy S8 drains battery fast even when charging, fast charge not working anymore

My Samsung S8 has started to run low on battery. If charging from 30% and an app is on it drains to 0% while charging.

Also it no longer charges fast even when it is switched off. Within minutes now my battery was 34 only using chrome and is down to 16 in less than 10 minutes. Never been like this before Lots of apps even whatsapp is not working on the background. Can a battery be replaced if required to do so? Or how do I solve this problem please. Thank you. — Mrsmmari

Solution: Hi Mrsmmari. Given that there are at least two symptoms happening on your S8 at this time (fast battery drain and fast charge not working), we say the problem is most probably due to a damaged charging port than a bad battery. The two issues you mention are usually the common signs of a charging port malfunction. Unfortunately, whether you have a broken charging port or a bad battery, you’ll still need professional help so you’ll most probably end up with repair in any of these cases.

To confirm that this is not a software issue, make sure that you recalibrate Android and the battery first. Here’s how to do it:

  1. Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.
  2. Charge the phone until it reaches 100%. Be sure to use original charging equipment for your device and let it charge up completely. Do not unplug your device for at least two more hours and also don’t use it while charging.
  3. After the elapsed time, unplug your device.
  4. Perform a warm restart by holding the Power and Home buttons simultaneously until the startup logo appears.
  5. Use your phone until it completely runs out of power again.
  6. Repeat steps 1-5.

Battery calibration is used if your device no longer shows the correct battery levels, or if battery has become erratic after charging like in your situation. If that won’t help in fixing the problem though, you should then do the factory reset trick.

If both software solutions won’t resolve your issue at all and you want a permanent fix for the problem, you need to let Samsung take a look at the device so they can recommend repair or replacement for it.

Alternatively, you can use your phone’s wireless fast charging capability if you don’t want to go through Samsung’s repair process. Wireless fast charge is slower than fast cable charging but it’s the only good choice for you if you don’t want to send the phone in.

Problem: Galaxy S8 severe battery drain issue after an update

Hi! I have a Samsung Galaxy S8 which has been amazing until today. I installed the October security patch the day before yesterday and this morning I noticed my battery was draining extremely quickly and charging very very slowly. I have it on medium power saving and I’m still losing 1% every 2-3 minutes. If it’s not in use, I’m losing 1% every 3-5 minutes. I optimized it earlier so background apps are closed, I keep my screen at about 30% brightness and I swipe out of apps as soon as I’m done with them. I haven’t gotten any error messages but when I clicked the link to fill this form out it gave me the option of using chrome or some red Samsung app. Don’t know if that’s weird but it’s never happened before because Chrome is my default. Typically I can use it throughout the day while at work and when I get home I’m at around 70% or so but today I was at 54% by the time I got to work and had to run home at lunch to grab a charger so it wouldn’t die right then. Help! I feel like an iPhone owner!! Thanks!

Solution: There’s no single effective solution for an issue like this. Battery drain issue can be triggered after an update but it doesn’t necessarily mean that it’s an Android issue. In some cases, a new Android version can suddenly make some apps change their settings and create conflicts. When dealing with an issue like this, it’s important to consider all the factors, then narrow them down towards resolution. Below are the things that you can try.

Refresh the system cache

When faced with post-update issues, it’s important to consider clearing the cache partition right away to ensure that there’s a new system cache for Android to use. The operating system needs up-to-date temporary files called system cache in loading apps and doing specifici tasks. Android makes use of this cache to improve its general performance. At times though, this cache gets corrupted after an update causing slow downs and bugs. To minimize situations like this from occurring, you can refresh the system cache found in the cache partition.

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Android logo displays, release all three keys.
  4. An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
  5. Press the Volume down key several times to highlight wipe cache partition.
  6. Press Power key to select.
  7. Press the Volume down key to highlight yes, them and press the Power key to select.
  8. When the wipe cache partition is complete, Reboot system now is highlighted.
  9. Press the Power key to restart the device.

Install app updates

Previously working apps may become a problem after an update. Keep in mind that updating Android won’t update the apps as well. Ideally, app developers must make necessary changes on their products to limit the chances of problems after an update. While this is true for many well supported apps, some may not be so. You can help by manually checking for available app updates right after you’ve updated Android. Be sure to keep your apps up-to-date by allowing Google Play Store  to download and install updates for them. Here’s how:

  1. Open Play Store app.
  2. Tap More optiones on the upper left (three horizontal lines).
  3. Tap Settings.
  4. Tap Auto-update apps.
  5. Select one of the following:
    • Over any network
    • Over Wi-Fi only
    • Don’t auto-update apps.

We suggest that you only update on wifi to avoid incurring additional costs.

Reset app preferences

This troubleshooting step ensures that all default apps and services are enabled. Some apps may need default Samsung and Google apps to work properly. If some of these default apps have been disabled by accident, or changed after an update, it may create a conflict with the apps that need them.

To reset app preferences:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Reset app preferences.
  5. Restart your S8 and check for the problem.

Reset all settings

This procedure is separate from the previous one as it covers all settings of your Android device and not just the apps. To do this, follow the steps below:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management > Reset settings.
  3. Tap Reset settings.
  4. If you have set up a PIN, enter it.
  5. Tap Reset settings. Once complete a confirmation window will appear.

Calibrate battery and OS

Sometimes, Android may lose track of the actual battery levels. To recalibrate the operating system so that it gets accurate battery level readings, do the following:

  1. Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.
  2. Charge the phone until it reaches 100%. Be sure to use original charging equipment for your device and let it charge up completely. Do not unplug your device for at least two more hours and also don’t use it while charging.
  3. After the elapsed time, unplug your device.
  4. Restart the device.
  5. Use your phone until it completely runs out of power again.
  6. Repeat steps 1-5.

Battery Usage

Fast battery drain is a perennial problem for both end users and manufacturers alike. In order to better manage the battery, Samsung provides a useful app that you can use to keep track of apps that consume power. This feature is in Settings and called Battery Usage. Make sure to use it so you’ll have an idea which apps to better manage.

Here’s how to open Battery Usage:

  1. Open Settings app.
  2. Tap Device maintenance.
  3. Tap Battery.
  4. Tap Battery Usage.

Under the Recent Battery Usage section, you’ll see a breakdown of the apps and services that uses the battery. If there’s an app that shows prominently on top of that list that you’re not using actively all the time, it may be one of the major causes for your battery drain issue. Recent Battery Usage section also shows the system apps like Screen, Android system, etc. in this list though there may be little to nothing that you can do about them. If Screen is the main culprit for the battery drain lately, you should consider dimming the screen to the lowest comfortable level.

Factory reset

This is may be the last in this list of troubleshooting steps but factory reset is often an effective way to return all parameters of the operating system to their normal setup. Make sure to do this if not one of our suggestions above won’t help.

To factory reset your S8:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.
  10. Set up your device again.

How to fix a Galaxy S8 that drains battery faster and won’t charge

Hello Android fans! Welcome to another troubleshooting article for the #GalaxyS8 device. We come to provide you solutions for some of the common problems a lot of S8 owners now face with their S8 devices. The main issue we address in this post is about an S8 losing power faster and no longer charging. We also discuss other related issues so feel free to browse through the cases below.

Before we proceed, we want to remind you that if you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Problem #1: How to fix a Galaxy S8 that drains battery faster and won’t charge

My Galaxy S8 is not holding a charge all day anymore. First off, let me say that I do not have the original charger, I know that’s a problem.  Right now, the phone is currently at 4% after being plugged up all night, and is currently plugged into my computer modem now (different charger)  and the battery percentage is decreasing instead of increasing. Can you help?

Solution: This kind of issue can happen for a number of possible reasons. Some of the common causes why a device may not hold a charge or drains battery faster includes the following:

  • too many apps running in the background
  • inefficient firmware coding
  • bad third party app
  • operating system bug
  • battery defect
  • Broken charging port
  • unknown hardware malfunction

Since there’s no direct way to know what the real reason for the problem is, you need to do a series of logical troubleshooting steps to narrow down the factors.

Apps

The most common reason why a relatively new Samsung Galaxy device loses battery power faster than expected is apps. If you’ve added plenty of apps to the system, some of them must be running in the background all the time, causing the constantly run and use resources. Social networking apps like Facebook and similar are notorious for being the number reasons for battery drain across all smartphone platforms. This is because these type of apps regularly communicate with remote computers over the internet to get new contents. The same is true to games or any other apps that need updated content every once in a while.

To check if you have an app issue, open the Battery usage utility tool under Settings > Device maintenance > Battery > Battery usage. Once Battery usage is selected, you’ll see a list of apps that’s been flagged by the tool to have consumed significant amount of power over a period of time. Use this list to get an idea which apps may be running all all the time or taking up power and to take necessary action to rectify the situation. If you noticed an app that you only use sparingly but remains on top of the list, it’s possibly doing a sloppy job at power management, or may even be a sign of something bad, like what malware or viruses normally do. Some developers may create apps meant to use a phone’s resources to do tasks you don’t necessarily know about, like mine cryptocurrency in the background. It’s up to you to determine whether or not the apps in the list are doing what you intend them to do or not. If you don’t think an app should be constantly running at all, try to remove it from the system and see what happens.

Use official Samsung Galaxy S8 charging accessories

While there are now excellent third party charging cables and adapters that you can use on your S8, it’s still highly recommended that you stick with the ones that came with the device. These accessories are ones tested and validated to work with your S8 and Samsung spent a lot of resources and effort in their research for it. Not using them is not just unwise but also puts your device at risk of getting damaged during charging. To see if you have charging issues with your accessories, try to get new ones or bring the phone to your local Samsung store. In there, try using the store’s official charging cable and adapter to top up the battery.

Android OS bug

Some battery drain issues are caused by an operating system bug. To check if that’s the case here, wipe the phone thru factory reset. Here’s how:

  1. Create a backup of your personal data.
  2. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Bad charging port

One of the common reasons why a Galaxy device may stop charging all of a sudden is a bad charging port. Most of the time, the common reasons for this includes water damage and physical damage in the system. Pins inside the port can sometimes become damaged or bent if you use incompatible third party charging cables. Try to use a magnifying tool to examine the charging port. If there’s dirt, lint, or residue, try to clean it with canned air. If there’s obvious damage like a visible bent or out-of-place metal pin inside, that means you have a hardware issue. Let Samsung repair the phone for you.

Problem #2: What to do if Galaxy S8 screen stays black and won’t turn on

Hi. I really need my phone this week. My phone is just making sounds when I turn it on and stuff like that and it’s LED indicator is working . But when I turn it on my phone just won’t display anything even the logo. is it a bug, error, or my screen is broken? It was working a moment ago. This is a Samsung S8. Please respond ASAP. Thanks!

Solution: Most probably, the problem has something to do with the screen. The phone is obviously not dead since it’s making a sound and the LED is being displayed. To check if the screen is prevented from working by an Android bug, try to boot the device either Recovery Mode or Download Mode.

How to boot a Galaxy S8 to Recovery Mode

  1. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).

How to boot a Galaxy S9 to Downlod Mode

  1. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the Volume Down key and the Bixby key, then press and hold the Power key.
  3. You’ll know if you’re on Download Mode when you see a screen that says “Downloading….”

Remember, if the screen works in any of these modes, that’s a clear sign that you have an Android OS issue. Be sure to factory reset the device in Recovery Mode to fix it.

If the screen stays dead or black, or if you can’t boot the device to any of these alternate boot modes, contact Samsung for support. Repair is most likely needed to fix it.

Problem #3: Galaxy S8 won’t charge or transfer files to PC

problem started with charging cord, saying to consider using factory cord. the problem evolved to now not being recognized when trying to transfwe files.i have master reset,changed cords,antried all usb ports,and keep getting unknown device.i have downloaded new drivers,and deleted from computer all exterior devices,and usb controllers,and let windows try and reinstall,and now get an error code that uploading driver failed.if i un hook and hook cord back up its back to the un known device in the control panel.i’m stumped.this is a one year old phone.

Solution: The signs you mentioned are consistent to that of a bad charging port problem. For this situation, you want to let Samsung check the hardware physically so they can advise you whether or not to repair or replace the phone.

Problem #4: Galaxy S8 stuck in Samsung logo screen, won’t boot up

Hi. I own a Samsung Galaxy S8. Someone gave it to me, but it didn’t work. I tampered with it, and got it to work perfectly. then I dropped it and it quit working again. I somehow got it to charge, and it worked, but when I tried to get it to sleep, it became unresponsive, then turned off, at 62%. I tried everything, but all I got was when I tried to turn it on, I get the “samsung galaxy S8” symbol, then it turns off. same thing with charging it. Could I please get help?

Solution: We don’t know the history of your device so we are mostly in the dark in this situation. We also don’t know how you tampered with it but if it involves flashing or rooting, consider bring all software information back to their defaults. Try doing a master reset first and see if that will help. If not, try to flash its firmware back to stock (the version that came with it from factory). If both these software solutions fail to fix the issue, then the problem is probably beyond your capacity to fix. Be sure get help from Samsung so they can do some digging further.

How to fix Galaxy S8 that’s unresponsive and screen is black all the time

The #GalaxyS8 is one of the top flagship Android phones at this time. And while it is an amazing device in its own right, it’s still prone to some of the common problems that affects many smartphones. Today’s troubleshooting guide will cover the steps on how to deal with a Galaxy S8 that has become unresponsive and with a screen that no longer works. Black screen issues are usually signs of bad hardware but in this episode, we’ll try to explore the possibilities of having a black screen issue having a software problem. We hope that our solutions will help those who encounter this problem.

Before we proceed, we want to remind you that if you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution.

Problem #1: How to fix Galaxy S8 that’s unresponsive and screen showing black all the time

So, I was using my phone this past Saturday, like normal, then suddenly my screen went black. Like totally black. I could feel vibration as I touched it and I could hear buttons being pressed but I could see nothing. I’ve tried the force restart but nothing is working and I can’t get into anything. Now, after lots of restarting and trying stuff, I see a green LED light and the phone’s normal sounds are different. It all sounds weird anytime I press buttons. I’m trying desperately to do a file transfer either from my old phone to my new phone or from my old phone to my computer.  Help please. — Christina Q

Solution: Hi Christina. First off, it’s not possible to move files to and from your phone if its touchscreen and/or operating system are not working (won’t boot up). These two are the basic requirements in order to allow a second device like a computer to communicate with your device. The the operating system (Android) must work normally so that a computer like a Mac or Windows can talk to it, and hence, transfer files. Of course, you also need to allow Android to bypass its built-in security feature that automatically blocks external intrusion by tapping on an option let your computer read contents. Without these two working, you can’t hope to get your data at all.

So, needless to say, unless your S8’s screen is fixed, there’s no way to know if file transfer is even possible in the first place. At this juncture, we can’t say if Android is working or boot up fine. Maybe it had hit a snag preventing it from booting up. Maybe the system has become unresponsive, causing the screen to stay black at this time. Since we don’t know the history of your device or the things that happened to it that might cause this problem, we can’t say for sure what’s going on.

Based on our own experience of fixing similar issues for years, a Samsung Galaxy screen does not just die on its own. A standard Galaxy screen can last several years as long as taken care of properly. If yours has become black all of a sudden (no accidental drops, no exposure to water, heat, or direct sunlight, no physical impact), the most likely cause must be software in nature. However, if the phone was physically damaged before this incident, stop wasting your time looking for a software solution. Instead, you want to let a professional check the hardware to see if there’s anything that they can do about it.

If you think the cause of the black screen problem is software, try our suggestions below.

Force restart

This should be the first thing that you need to do. Black screen is usually the most noticeable symptom that a system has stopped responding. To force reboot your device, you need to do the following steps:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Note: Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Also, allow up to 90 seconds for the reset to complete.

Turn off the device

If force rebooting your S8 won’t resolve the issue, that’s probably Android is stuck in an error it can’t get out of. Depending on the remaining battery level, let the phone rest for a few hours until the battery is empty. If the device was recently charged, it may take up to several days until the phone dies down on its own. Make sure that you allow your phone to shut off so you’ll know if it can recover afterwards.

Charge the phone using another known working S8 charger and adapter

Once the phone has been positively identified as totally off (no LED, no vibration, no sounds), let it charge for up to an hour using another set of charging accessories. The goal is to see how the phone behaves when charged using another cable and charger. Sometimes, a bad cable or adapter can cause charging problems so it’s good if you can eliminate this possibility early on.

Charge using a computer

Another good way to do here is to charge your device via a computer. The difference in power output from a computer’s USB port may correct the error the phone is dealing with at this time. Make sure that you let the phone die on its own first before you do this troubleshooting step.

Restart to Safe Mode

While it’s possible that a third party app may be behind the trouble, the primary reason why you want to boot your S8 to safe mode is to know if you have an Android operating system issue or not. Safe mode, while it does look similar to regular mode, is actually a totally separate software environment. This means that if your S8 goes to Safe Mode but not to regular mode, there’s either an app issue causing the problem, or that there’s a software bug that prevents the screen from turning on.

To boot your device to safe mode:

  1. With your S9 off, press and hold the Power key past the model name screen.
  2. When “SAMSUNG” appears on the screen, release the Power key.
  3. Immediately after releasing the Power key, press and hold the Volume down key.
  4. Continue to hold the Volume down key until the device finishes restarting.
  5. Safe mode will display in the bottom left corner of the screen.
  6. Release the Volume down key when you see Safe Mode.

To know which app is causing a problem, follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your S9 still refuses to power back on, repeat steps 1-4.

Boot the phone to Recovery Mode

Recovery Mode is a separate software environment that your Samsung device can boot up to to clear the cache partition, do master reset, restart, etc. If your device is still unresponsive at this time, make sure that you try booting to this mode so you can do some important troubleshooting steps.

IMPORTANT: In order to boot your S8 to this mode, it must be turned off first. So, again, make sure that the device is totally powered down before attempting the hardware button combinations below:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).

Should your S8 boots to Recovery Mode successfully, try to restart the device in the menu. Use the Volume buttons to navigate and the Power button to select.

If the phone won’t restart, go back to Recovery Mode and this time, do the cache partition wipe. If that won’t resolve the issue either, try factory reset, also known as master reset. This should also be an option that you can do under Recovery Mode.

Get professional help

If the problem is still there after booting to Recovery Mode, or if the device won’t even boot to Recovery at all, you’re out of luck. In this situation, your phone’s hardware must be damaged (screen or motherboard) so you need to let a technician check the phone physically. There’s no better way to do that than send the phone in to Samsung. If your S8 is still under 1-year warranty coverage, repair of this type may not cost you anything, unless there’s a need to replace the screen or some parts. To know the exact repair fee, be sure to talk to Samsung about it.

As much as possible try to avoid letting a non-Samsung technician open the phone and do the repair. If something goes wrong with that repair and you decide to let Samsung handle the rest, you will be unable to do so, even if you intend to pay for it. Your S8 will already be considered tampered with and Samsung will not even touch it. Unless you want to risk having an expensive paperweight, we suggest you let a Samsung technician take a look.

Problem #2: Galaxy S8 Active battery loses power very quickly, won’t turn on unless it’s plugged in

I’m new to the Android world. I just purchased a used Galaxy S8 Active. All seems good except that it turns off when the battery goes from 95-94% to 68% in a heartbeat and then won’t turn on unless plugged in. I’ve done the system reset as I read here as well as emptying the cache neither of which helped. Am I looking at a battery replacement? — David

Solution: Hi David. We’re most probably looking at a bad battery scenario here. Before you decide to have the battery replaced, we suggest that you try two things — battery and Android calibration and factory reset. These two should clear the software and help you determine if our suspicion is true. A newly factory reset device should not have a battery issue like the one you’re experiencing right now. If the same behavior remains after calibration and factory reset though, you can bet your S8’s battery is a mess.

To perform Android and battery calibration:

    1. Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.

Problem #1: Galaxy S8 losing battery faster and keeps showing moisture detected error

I have a Galaxy S8 through Xfinity Mobile. It has been nothing but awesome since Aug 2017. Until last week, I seen a notification which said something about “moisture detected in USB port, dry out before connecting charger.” I tried ducking the charger port, blowing in it, and just let the phone sit for 6 hrs. Everything seemed to be okay for 2 days. But then I noticed my battery dies much faster now. Yesterday, I had it on charge with the original cable, it was slow charging the whole time, after 2 hrs I only had 32% from 15%. It never did that before. Also, I have to charge it regularly throughout the day, whereas before I could go through my entire 9-hr work shift without a charge and still have 30-40% left, that’s with texting, making phone calls, checking emails, and playing a poker game throughout the day.

I let it sit in rice tonight for 2 hrs. It doesn’t seem to have helped. Next I was thinking about getting a new charger, the original Fast charge like it came with. The moisture message hasn’t shown up again, but the battery life is tremendously different. — Jessica Johnson

Solution: Hi Jessica. There’s no single factor that we can cite as the reason for your issue. In many cases where a phone’s battery seem to drain quicker than normal, a user must do a number of troubleshooting steps to determine the cause. In each and every case of battery drain, the factors are different so if you want to know what’s causing your own problem, you need narrow things down. Yes, you may have noticed that the issue first appeared after the phone started showing the moisture detected error but it doesn’t really narrow the real reason down. There’s a high chance that yours may be hardware in nature such as a broken battery or charging port. Below are the things that you should try to pinpoint the main cause:

Clear the cache partition

Android uses a set of caches in order to do tasks efficiently. One of these caches is the system cache, tucked away in the cache partition. The system cache is a set of temporary files, links of sites you’ve visited, advertisement files, among others and they’re used by Android to load apps quickly. In other words, the cache partition is an integral part of how Android works on your S8 in general. Sometimes, this cache gets corrupted, causing the opposite of what it’s supposed to accomplish. This makes apps load slower, affecting Android’s general performance. With this slower performance comes greater need for your phone’s computer (CPU) to compensate by working harder, which in turn, can cause unnecessary strain on the battery. To rectify the problem, the system cache has to be replaced with a new one. To ensure that your phone has a good working cache, follow the steps below to clear the cache partition.

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight “wipe data / factory reset.”
  5. Press Power button to select.
  6. Press the Volume down key to highlight “wipe cache partition.”
  7. Press the Power key to select.
  8. Press the Volume down key to highlight “yes” and press the Power key to select.
  9. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  10. Press the Power key to restart the device.

Perform battery and OS calibration

One of the least known reasons why a smartphone battery may, all of a sudden, stop working properly is the possibility of Android not getting accurate battery reading. This situation occurs for a number of reasons but one of the most common one is simple — the system has been running for a long time. Many smartphone users usually don’t think there’s a need to restart their devices regularly so oftentimes, phones work day in and day out for weeks or even months straight. This can sometimes be problematic for the system as complex as Android because bugs tend to develop after some time. One of such bugs can develop in the power management aspect of a system. Sometimes, Android may no longer be able to track battery levels accurately causing random shutdowns or restarts. It can also result to other power issues such as the one you’re experiencing. To see if your Android needs recalibration, follow the steps below:

    1. Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.
    2. Charge the phone until it reaches 100%. Be sure to use original charging equipment for your device and let it charge up completely. Do not unplug your device for at least two more hours and also don’t use it while charging.
    3. After the elapsed time, unplug your device.
    4. Restart your Galaxy S8.
    5. Use your phone until it completely runs out of power again.
    6. Repeat steps 1-5.

 

 

Install app and Android updates

Should Android and battery calibration won’t work at all, the next good thing that you can do is to ensure that all apps are up-to-date. Also, you want to make sure that Android runs the latest available version.

To check for app updates:

  1. Open Google Play Store app.
  2. Tap More settings at the upper right.
  3. Tap My apps & games.
  4. Allow Play Store to check for app updates.
  5. Tap UPDATE ALL button.

To check for possible Android update:

  1. Open Settings app.
  2. Tap Software update.
  3. Tap Download updates manually. Selecting this option will force the phone to check if there’s any available software update at this time.

Factory reset

If your phone still drains battery faster than ever everyday, you should consider wiping it by restoring its software environment back to their defaults. To do that, you need to do a factory reset. Here’s how:

  1. Make a backup of your personal data.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Once you’ve factory reset the device, try to see how the battery works when the software is at its default state. That means no third party apps and files in the system. So, you want to avoid adding your apps right away. Try to observe how your phone works when there are no apps other than the ones that come with the operating system for at least 48 hours. At this state, you expect the battery to last way longer. If the problem persists though, that’s a clear sign that you may have a battery or a hardware problem. In that case, you want to contact Samsung so your phone is repaired or replaced.

If battery drain issue returns after a factory reset and after adding apps

Chances are, your phone may work flawlessly after a factory reset but not after installing apps again. That’s because one or some of your apps may actually be to blame. If your S8 behaves this way after doing a factory reset, you can bet one or some of your apps is problematic. Try to use your phone for a full week like you normally would, then check battery usage under Settings > Battery > Battery usage and see what app is on top of the list. This is the best method to address the app that’s causing battery drain. If possible, uninstall the said app/s to fix the issue.

Problem #2: Galaxy S8 won’t charge, won’t turn on, data recovery when device is unresponsive

My Samsung Galaxy S8 has lost power, initial attempts to turn on displayed the screen prompting charging Charging resulted in no results. Tried a car charger, a USB port, a portable Anker battery source, and a wall charge. Tried several wires. All of these options worked with another Android device. I tried doing resets, nothing. I tried wireless charger with a charger for another android device. Nothing. 1. Is there anything i can do to get my phone to work? 2. Will i be able to recover photos from it if it cannot be revived? — Carl [email protected]

Solution: Hi Carl. In this situation, the main task that must be done is to power up the phone first. If you can’t do that even after trying different known working chargers and cables and wireless charger, there’s nothing much that you can do. And no, you can’t also get contents from your device if it’s unresponsive. In order to access data from your phone’s internal storage device, the operating system must be up and running. The touchscreen also needed in order to permit a second device like a computer to talk to the system and transfer files. If your S8 is dead and won’t turn on, your data are good as gone.

If your data are very important and worth over a few hundred dollars, try to get professional support from companies that specializes in data recovery. If you’re lucky and the issue is battery-related, which means that there’s a problem with the battery preventing Android from booting up normally, they should be able to replace the battery without wiping the device’s storage device. Data recovery is a tricky business and does not guarantee that it works 100%. It’s also an expensive process so be sure to get services from reputable companies only.
