how to fix S8 moisture detected error

What to do if Galaxy S8 keeps saying “moisture detected” and won’t charge

Many people expose their water resistant device to water and complain later. This post should be another reminder of what to do when a device like the #GalaxyS8 may stop charging due to moisture detected error, or after the phone has been wet. Just because an S8 is water resistant does not mean you want to intentionally expose it water or swim with it in the ocean or pool. High pressure water like in the sea waves or swimming pool can potentially damage an S8. Samsung’s IP68 rating on their devices are highly overrated and does not work reliably. Unless money is not an issue, we say you avoid exposing your electronic device to water to prevent problems. If you’ve already acted foolishly and now having a water damaged device, see our suggestions 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 install OTA update for AT&T Galaxy S8

I have a Samsung Galaxy S8 (SM-G950U) that was bought from AT&T. It is now on T-Mobile. BUT it has an old software version from over a year ago, G950USQU1AQJC. I would like to update it to Android 8.0, but as you point out, it will not work on T-Mobile. Calls to Samsung were useless. Clearing Cache did not help. Smart Switch still tells me my software is up to date QJC(ATT) but AT&T’s own website tells me that this version is maybe 6 updates old. The phone is unlocked (obviously.)  I am not comfortable with flashing on the side. What I want to know is IF I go buy an AT&T Pre-paid SIM card and put it in my phone, will the phone eventually (or at least within the 30 days the card is good for) get the OTA from AT&T and do the update? It’s $30 for the pre-paid card, so I want to be sure this will work before spending the money. Everything else has failed. Thank you.

Solution: We haven’t tried it yourself so we can’t give you 100% confirmation if it will work. There’s a good chance that it will though as long as the phone is provisioned properly by AT&T. Since it’s originally from AT&T itself, there’s a good chance that it will receive an update for Android Oreo. Over-the-air updates are managed by an automated system and we don’t know exactly how often AT&T’s system push updates for compatible devices. As long as your phone was in good standing with AT&T and you can use AT&T’s prepaid services without issues, you may be able to OTA update your S8.

If you have a friend who can let you borrow his or her SIM, we suggest that you go that route instead of buying a SIM card. Once you’ve inserted the SIM card, be sure to manually check for updates under Settings > Software update. If that won’t work, wait for 24-48 hours before attempting another check. Some carriers may set a certain period of time that a device has been continuously connected to their network before an update may be paused. Try to talk to an AT&T representative if your phone is still unable to update after the prescribed time period.

Problem #2: What to do if Galaxy S8 keeps saying “moisture detected” and won’t charge

I’m in the military and I’ve been in the field for about two weeks and while I was out there my phone was giving me moisture cant charge for a whole day until it just went to slow charge instead. I’ve tried to see if turning the phone off and charging it would work but that just displays moisture problem and wont let me charge at all. any ideas ?

Solution: If your S8 keeps showing the moisture detected warning, that’s probably because the charging port is wet or has presence of moisture. This is meant to prevent the phone from developing rust or corrosion but also to avoid shorting the motherboard. Corrosion in the charging port or around its vicinity can lead to more serious hardware issues in the long run.

If there was a chance that your S8 may had been wet in the field, we suggest that you do the most obvious thing first: dry the charging port.

Dry the phone

Water deposited in the charging port naturally evaporates on its own after some time but if the charging port has presence of other forms of liquid, you may need to manually clean it. Samsung advise against immersing the device in salt water, ionized water, soapy water, or hot water. If your phone was exposed to any other form of liquid other than fresh water, be sure to rinse it thoroughly in fresh water. Then, dry the phone by wiping it with clean soft cloth and  gently shaking it to dislodge as much residue in the charging port as possible. If there’s any residue remaining in the charging port, the device may refuse to charge.

Avoid sticking anything inside the charging port to avoid damaging metal pins or connectors. You can also try to gently blow into the port to dry it out. Do not use a can of compressed air as that might push moisture inside, even if you think the phone’s water resistance protection is intact.

If none of the above works, or if you’ve already tried them before contacting us, then you’ll need to let Samsung handle the situation. Go to your local Samsung store and have the phone repaired.

Wireless charging

If you wish to turn the phone on so you can back your files up to the cloud, try to charge the phone wirelessly. Your S8’s wireless capability does not need a working charging port so it should work even if the charging port is damaged or wet. Be sure to use an original Samsung wireless charger for this task.

Problem #3: How to fix a Galaxy S8 that has stopped charging

Hey there thanks for your site. I’ve had an issue for several days with my galaxy S8. It stopped charging on my normal original charger. i let it go for about 24 hours, then switched to a 1A charger and it registered charging. That worked but slowly. After i was able to use my rapid charger no problem. Then a few days later i got a few phones calls and put it on and off the charger and bam it stopped charging all together. I did the soft reset, used 4 different bases and 3 different cords. I plugged it into the computer and that worked. i let it charge for 50% until turning it on, in which it stopped charging! Not sure if there’s an easy solution, it won’t link to my computer currently to get my pictures. I just watched a video on changing the battery and that’s extensive. Any help would be great please and thank you!

Solution: We have no way of knowing whether the issue is being caused by a bad battery or by some other hardware failure without physically checking and diagnosing the phone ourselves. We suggest that you do two things instead:

  • wirelessly charge the device, and
  • factory reset it.

Charging your S8 wireless, as pointed out above, is a good way to charge the battery in this situation. Once the phone boots up normally again, you can then start backing up your files to the cloud (if USB connection to computer is not possible). Alternatively, you can move files to your computer wirelessly with the help of third party apps like Shareit or similar.

Factory reset may be a necessary troubleshooting step for you if you want to find out if the issue is being caused by a software bug. We don’t know the full history of your device so we can’t say whether or not software is to blame. If your phone continues to fail to charge by cable after a factory reset, then you can assume that bad hardware must be causing it. To fix the issue, you should send the phone to Samsung.

For reference, these are the steps on how to factory reset your S8:

  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).
  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.

Problem #4: Galaxy S8 keeps going back to home screen when using apps after phone got wet

My phone got wet. It didn’t seem or look like I had any issues with my phone until I went into one of my apps. It’s letting me in my apps but then it kicks me out & put me back to the front of my phone screen..so I then have to hit the left symbol on the front bottom of my screen & get back into the app I was in. Its upsetting me bc I can’t even text a whole sentence or online shop or text because it’s not letting me stay in the app. I have no clue what to do & I hope you’ve had this type of problem before & that it can easily be corrected. I don’t want the aggravation of having to get another phone & having to re download all my apps..texts..photos..ect. Thank You for your attention into trying to help me solve this upsetting..stressful & frustrating situation!

Solution: The Galaxy S8 is a water resistant device and should offer basic protection against splashes or even a brief, low-pressure dunk in a pool. However, this water resistance protection may be compromised if the phone is physically broken or accidentally dropped before. If your S8 was no longer protected from water exposed before you got it wet, it’s possible that water may have seeped inside and into some parts, causing the problem you’re experiencing right now. We suggest that you let a professional check the phone to see if there’s any moisture or water left in the screen area or in other parts. We don’t think bad software is to blame for this issue so doing some software troubleshooting is pointless. You can, of course, revert all software information to their defaults by doing a factory reset but we doubt if that will make any difference at all.

How to fix Galaxy S8 moisture detected error, water damaged hardware?

Hello and welcome to today’s #GalaxyS8 troubleshooting article. This post will try to answer some of the common issues that affects a lot of S8 users — water damage, moisture detected errors, and failure to boot up.

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: Will Samsung repair a water damaged Galaxy S8?

Hi. I have a Galaxy S8 and it has water damage. I took it into my pool (I know, foolish of me) and it turned off almost automatically. The screen is unresponsive and stays black. There is a red LED that keeps flashing and the flashlight is in a constant strobe light setting it seems like. I have it in rice right now, but I don’t know what else to do. I do not have insurance on the phone either, would samsung still repair it? — Jack

Solution: Hi Jack. The Galaxy S8 has water resistance protection so a quick, shallow dive in a pool should be okay. The only instances that you don’t want  to intentionally dunk your phone in water are the following:

  • if the phone has been accidentally dropped before
  • if there are visible cracks in the screen or body of the device
  • if the phone’s hardware has been previously tampered before (if it’s been repaired)

Samsung’s water resistance is overrated and there had been many cases in the past that even brand new devices out of the box will fail if soaked in water within IP6’s limit (of up to 1.5m for 30 mins). In other words, water resistance protection sometimes is not 100% reliable. That’s why, as much as possible you don’t want to bring your device with you while swimming or diving in a pool or in the ocean.

If your S8 was normally working before it took a dive, then you’re right — it definitely has water damage.

Samsung treats water damage as customer misuse, which automatically voids the standard warranty. They won’t repair your S8 for free, even if it’s still within the standard warranty period of one year. If you want them to repair it for you, you must shoulder the repair fee and almost certainly the cost parts replacement as well. Depending on what parts were damaged, you’ll most likely spend upwards of $200 for Samsung repair. This is a conservative estimate and the total repair cost can easily balloon way high especially if there’s a problem with the motherboard as well. To get an accurate estimate, we suggest that you bring the device to Samsung so they can examine the hardware.

Problem #2: How to fix Galaxy S8 moisture detected error

For about the past week, on and off my phone will notify me saying android has detected moisture in the charging port. The problem is i have never used the water resistant feature for pictures etc and it has never been put in water or had water in it so i was wondering what do i do. — Specialkkellermann

Solution: Hi Specialkkellermann. Moisture detected error can show up due to a number of reasons. Let’s discuss them briefly and the possible solutions that you can try.

Moisture detected error due to traces of liquid or water in the charging port

The Galaxy S8 has a liquid sensor in the charging port designed to prevent charging and warn the user that the port is wet. This is the primary reason for most moisture detected cases reported to us. To ensure that there’s no tiny amount of water or liquid in the charging port, leave your phone near a warm area in your house for the entire day. Water naturally evaporates on its own after some time. Place your phone near an indirect source of heat like the back of a computer tower or TV for at least 12 hours. DO NOT expose the device to direct sunlight or place it near an oven or furnace. Remember, your goal here is to get rid of possible small amounts of liquid or water and not to boil something up.

Also, do not use anything that might push water or liquid inside your phone further such as a hair dryer or can of compressed air.

Moisture detected error due to software bug

Last year, we saw an abnormal rise in number of moisture detected cases for the S8 after a software update. Many users reported that their phone kept showing the error even though they haven’t been near water or exposed to liquid. The problem coincided with the latest Android update at the time so we easily correlated the two. We don’t know if the problem has resurfaced but at this time, you’re the first case that reached out to us regarding this error. In order to cover for a possible software issue though, we recommend that you factory reset the device and see what happens afterwards. Here’s how to do that:

  1. Create a backup of your files and other 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.
  11. Check for the problem.

Moisture detected error due to broken charging accessories

Some rare cases of moisture detected errors were caused by faulty charging cable and/or adapter. Make sure that you have good working charging accessories before charging your phone. To test if the error is due to bad charger or cable, borrow a know official charger for the S8 and use it to charge your S8. If you have the chance to visit a Samsung store, try to use their S8 charger and see if that will fix the problem.

Moisture detected error due to bad charging port

It’s not easy to know if the reason for moisture detected error is being caused by a charging port but this is one of the common causes of this problem. It’s usually a Samsung technician that should test this one out so don’t attempt to open the phone just to see how the charging port appears.

Moisture detected error due to unknown hardware malfunction

Some other hardware malfunction that might result to moisture detected error includes a bad battery, bad Power Management IC, or some other motherboard failure. If nothing works after doing all our suggestions above, then you can assume that there’s hardware failure behind the trouble. In this case, you’ll need to send your phone to Samsung for repair.

Problem #3: Galaxy S8 won’t turn on and stuck on red Verizon logo screen

Heya. I have a Samsung Galaxy S8. Saturday i woke up and my phone had restarted itself and was stuck on the verizon red screen. I had had this happen to me 5 months earlier and I had to factory reset and then things were back to normal. This time I attempted to try restarting it normally as well as reboot in safe mode. Alas, this did not work and still got stuck on verizon red screen. So then I bit the bullet and said i’ll do a factory reset. I did, and it still gets stuck on verizon red screen. I have factory reset it twice more afterwards to make sure all apps were deleted along with everything else, and it still gets stuck on the verizon red screen. Any ideas on whats wrong or how to fix this, or is it time to get a new phone ???\_( ‘_’ )_/ Cheers. — Alexa Alexa

Solution: Hi Alexa. If multiple factory resets via Recovery Menu did not fix the problem, your phone’s bootloader may had become corrupted for some reason. You can try to reflash it but it’s there’s no guarantee that it will work afterwards. Flashing the bootloader is usually only recommended for advanced Android users. We don’t recommend that you try it if you haven’t heard of it, or if you’re not confident to do it at all. Flashing can potentially damage the software for good so you may end up with a paperweight afterwards.

Below are the general steps on how to flash a bootloader in a Samsung device. Exact steps may be slightly different for your particular phone model.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Samsung repair

The best solution that we can tell you in this case is to send your phone to Samsung. If the cause of the problem is misconfigured or corrupted software, they may be able to easily fix your S8 by reflashing stock firmware to it. If it can’t be fixed by a software solution, they wil most likely replace it with another S8.

Galaxy S8 keeps saying its offline when using Google app

Hello and welcome to our latest #GalaxyS8 troubleshooting episode. We’ve been getting a lot of S8 issues lately so this post is one of our responses to them.

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: Galaxy S8 battery drain and lose of storage space after an update

After my last update my battery drains and i keep losing storage on my phone. I have uninstalled almost all my apps. My storage was 5GB a couple of days ago then it dropped to 1GB. I havent done anything to use up my storage. I get a message every couple days that some apps are overloading my cpu and when i looked to see what apps are using my battery it’s device maintenance, gear vr service, settings, voice wake up. It shows that those apps are using 100% of my battery when my battery gets low. I have cleared my phones cache. Its been doing this for a couple of weeks now.

Solution: Without a full history of your Galaxy S8, it can be hard to know what exactly is going on. We suggest that you return all software information back to their defaults and observe what happens afterwards. To factory reset your S8:

  1. Create 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.

If the problem returns after a factory reset, you should then check the possibility that one of the apps is causing it. Try running the phone on safe mode for few consecutive days and observe it. If storage appears to work normally and won’t ballon as you’ve described, one of the third party apps must be causing it. To boot your S8 to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name 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. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.

To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and 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 S8 is still problematic, repeat steps 1-4.

Problem #2: Galaxy S8 moisture detected error after an update

My cell phone has never been exposed to moisture but after a system update I keep randomly  getting the message: Check charger/USB port Moisture has been detected in your charger/USB port… I’ve done the Liquid Damage indicator check, – negative. I’ve started the cell phone in safe mode, – still have the message. When this message is showing I can’t charge my cell phone. Please help.

Solution: If moisture detected error started after an update, your device may be one of the few ones affected by a bug that sends incorrect reading of the USB port state to the operating system. The most effective solution for this bug so far is unit replacement but some users were able to resolve it on their device by wiping the cache partition or factory reset. If you haven’t tried these possible solutions yet, we suggest that you try them before sending it in.

  1. To wipe the cache partition:
    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 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.

For steps on how to factory reset, refer to Problem #1.

Problem #3: How to bypass FRP on Galaxy S8

I’m trying to bypass FRP with OTG cable and file I downloaded.  Phone doesn’t see flash drive when plugged in. Phone is at Google page asking for email and password.  I’ve unplugged and re-plugged cable but no luck. Any suggestions? Sorry, I don’t know what Android version.

Solution: Factory Reset Protection is a security feature added a few years ago to discourage thieves from using stolen devices by factory resetting them first. Initially, FRP was buggy and has a few loopholes, including one that allows an OTG device unlocking the phone. Samsung has since patched these bugs up and at this time, we are not aware of any unofficial way to bypass FRP. If you are the legitimate user of this S8, you have two options:

  • enter the correct Google username and password
  • bring the device to Samsung

If your S8 can currently connect to wifi, you can try to reset your Google account password in another device first, then use the updated credentials to bypass FRP. If you’ve already tried that, then you have no other choice but to get support from Samsung.

Samsung has a special flashing tool that can erase the current security settings of your device to bypass FRP. Make sure to bring the original proof of purchase and a valid ID for this purpose.

Problem #4: Galaxy S8 keeps saying its offline when using Google app

My S8 suddenly started saying I’m offline whenever I try to Google something even though I am logged on to my home wifi. I’ve tried restart, full turn off/ wait 30 minutes and turning wifi off then back on. It works randomly, but less than it doesn’t work.

Solution: Try clearing the data of Google Services Framework to fix it. These are the steps:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Show system apps.
  5. Find and tap your app.
  6. Tap Storage.
  7. Tap Clear Data button.
  8. Restart your S9 and check for the problem.

If clearing Google Service Framework data won’t work, remove your Google account from the device, then sign back in.

What to do if Galaxy S8 is losing battery faster and keeps showing moisture detected error

This troubleshooting post will try to answer two of the common problems for the #GalaxyS8 — moisture detected error and battery drain issue. While we don’t touch on what specific steps that you can do when faced with moisture detected error, we’ll show you the troubleshooting steps for your problem if your S8 won’t appears to lose battery power fast.

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: 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.
