Samsung Galaxy S6 users continue to deal with bad battery life, even after the arrival of Doze and Android Nougat. Today, we want to address those concerns and offer some tips to help you fix bad Samsung Galaxy S6 battery life if you’re running Android Marshmallow or Android Nougat.
The aging Galaxy S6 comes with a non-removable battery. While the presence of a non-removable battery may not matter to some Galaxy S6 users, there’s no question that it puts added importance on the stock battery found inside the device.
We, and many others, have gotten adequate battery life out of the aging former flagship, but some users are seeing major Galaxy S6 battery life problems as we push into 2018.
Android Marshmallow’s Doze feature helps, so do the changes on board the Galaxy S6 Android Nougat update, but we’re still seeing some complaints about abnormal drain from Galaxy S6 Android Marshmallow and Nougat users.

How to Fix Bad Galaxy S6 Battery Life
With that in mind, we want to try and fix bad Samsung Galaxy S6 battery life for you. This guide delivers help to get better battery life on Samsung’s current flagship if you’re running Android Lollipop, Android Marshmallow or Samsung’s Android Nougat update.
Find Apps Eating Up Your Battery
The first recommendation we always make if your battery life turns south is a quick check on your third-party applications. If you want to fix your bad Galaxy S6 battery life, you’re going to want to keep an eye on applications for potential problems. They’re often the problem.
Applications, third party and stock, have a tendency to put a huge dent into the battery life on any smartphone, not just the Samsung Galaxy S6.
If you use an application a lot, it’s going to drain your battery. But there are also times where bugs or issues might cause an app to go rogue and start abnormally draining the device’s charge.
To combat this, head into your Galaxy S6’s settings and start taking a look at the effect that some of your applications are having on your battery life.
The Galaxy S6’s battery section in settings will give you detailed analysis. If you notice anything out of the ordinary, it’s time to start taking a closer look at your applications.
If you think an app is draining more battery life than it should be, try reinstalling the app it to see if that corrects the issue.
If the problem persists, try uninstalling it (if you can) to see if that has a positive effect on your overall Galaxy S6 battery life.
If you can’t figure out which app might be causing trouble, you’ll want to boot the Galaxy S6 into Safe Mode in an effort to single out potential troublemakers.
Booting the device into Safe Mode disables third-party apps and allows you to isolate apps that could be causing the problems.
Here’s how to boot the Galaxy S6 into Safe Mode:
- Power down the device. Then, press & hold the power button and volume down key.
- Once it boots up, you can let go of the power button but keep the volume key held down.
- When you have successfully entered into Safe Mode, you will notice the text ‘Safe Mode’ at the bottom left corner of the screen.
Sleep Apps When You Aren’t Using Them
Samsung’s Galaxy S6 Nougat update brings a feature that could help you conserve your precious battery life.
Android Nougat allows you to sleep applications so that they can’t suck up your Galaxy S6’s battery life in the background. This will help you get a handle on known resource hogs like Facebook.
To sleep an application on your Galaxy S6, you first must have Nougat on board. If you are running Android Nougat, press and hold on an app icon. You should see a few options popup.
From there, choose to sleep the selected application. Use this regularly and you could see a nice boost to your battery life.
Use the Power Saving Modes
The battery usage screen is a lot cleaner in Android Nougat. If you head into there, you’ll notice two battery saving functions.
One of these power saving modes is a a middle of the road option. The other is a Maximum power saving mode that can help you preserve your battery in dicey situations.
They are customizable in that you can adjust items like screen brightness and kill off background network usage.
If you want more control over your device’s battery, you probably want to upgrade to the Android Nougat update.
If you’re stuck on Marshmallow, your Galaxy S6 is also equipped with two power-saving software features.
If you head into the device’s Settings and slide on over to System and then Battery, at the top you’ll notice two features. One is called Power saving mode. The other is called Ultra power saving mode.
When you turn Power saving mode on, it will limit your maximum CPU performance, reduce screen brightness and overall frame rate, turn off the touch key lights, turn off vibration feedback, and reduce the time before the screen is turned off when you receive notifications. It’s a feature that you should be familiar with because it works.
If you’re really hurting, you can try Ultra power saving mode. Ultra power saving mode will apply a grayscale theme to your Galaxy S6 and it will limit your usable applications.
Use Device Maintenance
Android Nougat also comes with a new Device Maintenance mode in your device’s settings.
Once you open it up you’ll come to a screen with a few options including Battery, Storage, RAM and Device Security. Each of these comes with a subset of choices from power saving modes to performance enhancements.
Dig into each one of these categories and find a combination of settings that works for you and your Galaxy S6’s battery.
Restart the Samsung Galaxy S6
If you start noticing weird battery drain, you should try performing a simple restart to see if that returns things to normal.
Most of you know how to restart the Galaxy S6 but we’ll remind you anyway. Hold down the power button, confirm that you want to turn it off, and then hold the power button down to turn it back on.
Disable Unnecessary Services
If apps aren’t the problem and a simple restart doesn’t work, it’s time to start fiddling with some settings and working on some of your habits.
In our experience, disabling features when they aren’t in use tends to have a positive impact on overall battery life.
We recommend shutting off Bluetooth connectivity when you don’t need it, NFC when you don’t need it, GPS when you don’t need it, and cellular data when you don’t need it.
You should also try shutting off VoLTE and/or Wi-Fi calling to see if that helps improve your device’s battery life.
You can turn all of those off from inside the Samsung Galaxy S6’s settings and you can easily monitor them with a quick swipe down from the top of the device’s screen.
One thing that we’ve noticed is that poor cellular coverage is often to blame for bad Android battery life. When your phone needs to search hard for a signal, it runs the battery down faster.
Keep that in mind when you’re in spotty areas. You may need to turn on Airplane mode when there isn’t a strong 4G or LTE signal in the area.
Try Using a Black Wallpaper
Switching to a black Samsung Galaxy S6 wallpaper could help deliver better Galaxy S6 battery life thanks to the way Samsung’s AMOLED displays consume power.
The device does not come with a default black wallpaper but you can search online for one. There are tons of them out there.
After you’ve downloaded one, go to Settings -> Personal -> Wallpaper -> From Gallery -> and then set your black Galaxy S6 wallpaper.
Replace Your Launcher
While Samsung’s made a number of improvements to its UI and its launcher, you can try replacing it with another launcher to see if that improves your Galaxy S6 battery life.
There are tons of different launchers to choose from though the Nova Launcher is one of Android’s most popular choices. We’ve gotten great results with it so it’s certainly worth a shot.
Factory Reset the Galaxy S6
If you can’t find any solutions that work, you should consider a factory reset. This will wipe all of your files so you’ll need to make a backup of your important files before starting the process. Factory resetting a device can have a positive impact on battery life though it should only be used as a last resort.
To factory reset the Samsung Galaxy S6, go into Settings -> Personal -> Backup and reset. From there, select Factory Data Reset. From there, select Reset Device.
Buy a Battery Pack
If you’ve tried everything, including a factory reset, maybe it’s simply a case of feeling underwhelmed by your battery. In years past, Galaxy S users were able to easily swap out the battery with an extended battery. Not this year.
The Samsung Galaxy S6 battery is non-removable and it’s clear that DIY projects are going to be tough to pull off. What this means is that most of you are are going to need to either keep a close eye on your habits or buy a battery pack.
If you’re willing to shell out a few dollars to improve battery life, Mophie’s got a Juice pack available for the Galaxy S6.
Mophie makes our favorite battery cases and the Galaxy S6 case will help you squeeze some more battery life out of your new phone.
Buy a Battery Bank
If you don’t want to put your Galaxy S6 in a bulky battery case you might try using a battery bank.
Battery banks are small, portable battery packs that can charge your Samsung Galaxy S6 up to seven times.
There are plenty of options out there but here are a couple of our favorites:
Contact Samsung And/Or Your Carrier
If you don’t want to spend money, get in contact with Samsung or your carrier to see if they can provide some help.
If you’re under warranty, and they determine there is a serious problem with your battery, you should be able to get a replacement free of charge. Mileage will vary.
Wait for the Galaxy S9 If You Want the Best Software
If you plan on keeping your next phone for awhile you should strongly consider waiting for the Galaxy S9 launch.
If you're the type of person that typically waits two, three, four, even five years to upgrade your phone, the Galaxy S9 is probably worth waiting for.
Samsung probably won't advertise this on stage during the Galaxy S9's launch event, but the devices should receive at least two years of major Android OS upgrades and several more years of bug fix updates and important security patches.
While it might be tempting to go with a cheaper alternative like the Galaxy S8 or Galaxy S7, their software support will be coming to an end much sooner.
The Galaxy S9's hardware also ensures the device will get robust versions of Samsung's next OS upgrades. Samsung's Android updates for older phones are often limited by aging hardware.
The Galaxy S9 should launch with an improved version of Samsung's Experience UI. Rumors point to a brand new UX complete with upgraded AI, Bixby 2.0 (an upgraded version of the Galaxy S8's personal assistant), and a take on Apple's Animoji feature on the iPhone X.
The Galaxy S9's software will reportedly include animal characters and allow users to share them with friends across messaging apps.
If you plan on keeping your next phone for several years and you want the latest features, fixes, and patches without having to install custom software, consider waiting a few more weeks to make your move.
