The Samsung Galaxy S6 comes with a non-removable 2550 mAh battery. It’s big but users continue to encounter battery life problems with the phone, even after the arrival of Marshmallow and Doze. Today, we want to address those concerns and offer some tips to help you fix bad Samsung Galaxy S6 battery life.
Last year, Samsung introduced its all new Galaxy S6, a device that comes packed with a number of high-end features including a new design language that features metal and glass, a new 16MP camera, and the company’s TouchWiz UI. It also comes with a non-removable battery, a big change from Samsung’s previous Galaxy S designs.
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 Galaxy S6.

While we and many others have gotten adequate battery life out of the Samsung Galaxy S6, there are those that are seeing major Galaxy S6 battery life problems. Android 6.0.1 Marshmallow’s Doze feature will help but we’re still seeing some complaints about abnormal drain.
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 or Android Marshmallow.
Find Apps Eating Up Your Battery
The first recommendation that 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 are 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 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.
Restart the Samsung Galaxy S6
If you start noticing weird battery drain and or your Galaxy S6 starts heating up, 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 Wi-Fi connectivity when you don’t need it, 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 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.
Start 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.
Start Using Galaxy S6 Software Features
The Samsung Galaxy S6 comes equipped with two software features that you should know about if you’re experiencing bad battery life or if you’re concerned about the potential for bad Galaxy S6 battery life.
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.
Replace Your Launcher
While Samsung’s made a number of improvements to TouchWiz and its launcher, you can also 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, 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.
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.
Install Nougat If You Value Your Security
If you store sensitive information on your Galaxy S6 or Galaxy S6 Edge you'll want to consider installing the Nougat update soon after it arrives for your device.
Google and Samsung release monthly security patches that deliver named, and unnamed, patches for potential exploits.
The Galaxy S6 Nougat update that's rolling out right now delivers the February security patch though we could see some of these updates push out with Samsung's new March security update. You can read more about their contents on Samsung's website.
If you missed an older security update (January, December, etc), you'll likely be forced to download it/them before you can obtain Nougat.
Important security patches are just a part of the Nougat update for the Galaxy S6.
Your Galaxy S6 Android 7.0 Nougat update should also bring Samsung Pass, a service that serves as a master key to all of your various logins.
Instead of relying on a password and ID to protect your identity, Samsung Pass uses the Galaxy S6's fingerprint scanner to keep your information safe.
It's extremely easy to setup and it should be useful to anyone that values security.
