Problem 1: Galaxy S6 drains battery faster after installing an update

After the latest 3 updates to my device, the battery dies significantly faster. The only changes I found to my system was a font change. Even on low brightness and battery saver mode (the basic one), while not using my phone, it will only last about 4-5 hours. It used to last all day and I would just charge it at night. This change was sudden and right after all the updates (since I had been putting them off for a long time). I’m worried that it is planned obsolescence and the updates didn’t really fix anything, but instead made many background things out of control to drain the battery faster in an effort to get me to buy a newer model.

Also, for Android Version, I am not sure which mines is. I never installed a different version? /sorry to be so clueless. — Sam

Solution: Hi Sam. Planned obsolescence or not, battery drain is a perennial issue that can happen in both new and old devices like your Galaxy S6. There’s no literature that can confirm if Samsung employs the same trickery Apple uses to slow down iPhones with weaker batteries. We’re pretty sure Android developers will most likely reveal the same scheme if it’s present on Samsung devices. Android operating system is a more open platform compared to Apple’s iOS so even end users can monitor their battery’s health.

It’s also not surprising to us that older devices tend to show significant battery drain issue following installation of latest Android versions. In fact, you’re not the first person to tell us that the battery no longer seems to last as long after every charge. Almost every Android user seem to have the same thought.

Lithium-ion batteries are limited

The earliest Galaxy S6 devices were released almost 3 years ago so at this time, we expect that millions of original S6 batteries are nearing their end of life. Even if you take good care of your phone by doing maintenance on it regularly, keeping the storage clutter free, and charge the phone properly (by doing shallow charges instead of fully charging it), your lithium-ion battery will start showing significant capacity loss after a year of using it. The more you use, charge, discharge, and charge the battery again, the shorter its life becomes. Do that day in and day out for over 2 years and you can’t expect the same battery performance at all.

Use an app to track battery stats

If you want to know important numbers about your battery, including a rough estimate on long it will last or whether or not it’s time to have it replaced, we recommend that you install third party apps like AccuBattery app. You can visit Google Play Store and find similar apps.

How to diagnose your Galaxy S6 battery

Knowing the causes of your battery ills can be tricky but there are a few important steps that you must do.

Consider your apps

In  a lot of cases, users are quick to pin blame on the update or the battery itself but not in the fact that they may be running a lot of apps or poorly coded apps. In case you’re not aware, not all apps are built with the same expertise. Some may be optimized to efficiently run while others, not so much. As a user, it’s your responsibility to screen your apps thoroughly and to remove problematic ones.

Check apps running in the background

Another reason why battery drain occurs is a lot of apps running simultaneously at the background. Make sure that you put non-system apps to sleep if you’re not using them to prevent the battery from working harder. If you’ve installed Android Nougat in your device, you can easily put apps to sleep by doing the following:

  1. Open Settings app.
  2. Tap Device maintenance.
  3. Tap Battery.
  4. Scroll down to the bottom and tap Save Power button under App power monitor.

If you don’t have Android Nougat yet, consider installing apps like Battery Doctor to disable apps running in the background.

Uninstall apps

It can be said that apps are the lifeblood of smartphones but too much of it can suck your battery dry in a very short time. Many Android users have the tendency to install apps at whim, then forget about them. Make sure that you are not one of them. Remove apps that you don’t need. Learn to trim down on apps to ease pressure on the battery. Remember, the more apps you add in the system, the more cluttered the device storage becomes. There’s also a higher chance of apps running services you really don’t need in the background. If you have a lot of these apps running all the time, you can’t expect the battery to last long everyday.

Let Samsung replace the battery

If you’ve determined that the battery has lost a significant capacity at this time, the best course of action for you is to replace it. If you don’t feel confident in replacing the battery yourself, let Samsung do it for you to ensure that it’s done properly.

Problem 2: Galaxy S6 won’t charge by cable or wireless charger

My phone has been having charging problems first starting when the cable wouldn’t charge my phone. So i switched to using the wireless charger and that has been working for a week or so. But recently my phone died and i go to use the wireless charger and the only thing that shows up is the battery symbol with a lightning bolt in it. My phone will not turn on at all. I even plugged it into a computer and my computer does not register that its connected. Any help you have would be much appreciated and if you have any questions about my problem just email me back. Thanks. — Evan Bogler

Solution: Hi Evan. If both cable and wireless charging has stopped working altogether, then the problem is most likely found in the motherboard. To diagnose the phone, you need to let a technician check it physically. If possible, let Samsung do the hardware diagnostics for you. Otherwise, you can bring the device to a local service center.

Problem 3: Galaxy S6 won’t charge, wont’ turn on

HELP! My son got this phone from his aunt. He’s so upset. we continue to have problems when he runs it down to about 5%. we turn off and plug in. sometimes it wont turn on. So I’ve done everything you suggest to no avail! I haven’t had to do a safe recovery as of yet, but now I can’t get it to charge or turn on at all. My husband checked the output for battery and it’s fine. When I plug it in, sometimes it will beep but nothing shows on phone, the battery indicator..nothing…please help me I can’t afford to take to a tech. he plays on it all the time, it’s not active with a provider just for games and it’s a special treat to have this. thanks in advance. — Melinda

Solution: Hi Melinda. There’s a number of possible causes for your problem. Here’s how to troubleshoot it.

Check the charging cable and adapter

The first troubleshooting step that you want to do is to determine if there’s an issue with the charging accessories. If possible, use a different charging cable and adapter to charge the phone. This step should eliminate the possibility that your phone is simply lacking power because it does not charge properly or at all.

Use a wireless charger

The Galaxy S6 is wireless charging capable so it’s a good idea to see if it will charge wirelessly. If you don’t have the wireless charger, you still need to buy one so, it still means spending something. Keep in mind that buying a wireless charger will not guarantee that it will work. If possible, try to test it with a known working wireless charger first before getting one for yourself.

Try to turn the phone on to alternate boot modes

If your phone will still not power on, you can also consider booting the device to other boot modes to see if that will make a difference.

Boot in Recovery mode

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

Boot in Download Mode

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.

Both Download and Recovery Modes run independently of Android so if the reason for the problem is Android-related, your phone should charge again in any of these modes. But if the phone won’t charge at all, you should consider sending it in for repair.
