How to Fix Bad Samsung Galaxy Android 5.1.1 Battery Life

With these Samsung Galaxy Android 5.1.1 battery life problems in mind, we want to try and fix bad Samsung Galaxy Android 5.1.1 battery life for you.

This guide delivers help to get better battery life on Samsung’s Galaxy S6, Galaxy S6, Galaxy S5, and more.

Find Apps Causing Problems

We’re already seeing Galaxy S6 and Galaxy S5 users blame Android 5.1.1, Samsung and their carrier for battery life drain after Android 5.1.1.

While Android 5.1.1 might have something to do with it, there’s a good chance that a third-party application or your bad habits are to blame.

Apps, third party and stock applications, impact battery life on your Galaxy. If you use one of your phone’s applications a lot, it’s going to drain your phone’s battery. But there are also times where bugs or issues might cause an application on your phone to start draining the battery. This can happen immediately after an update release like Android 5.1.1.

It’s time to take a peek at your apps to see if you notice something out of the ordinary.

If you own a Galaxy S6, Galaxy S6 Edge, Galaxy S5 or any other Galaxy device running Android 5.1.1, head into your settings and start taking a look at the effect that some of your applications are having on your device’s battery. Lollipop will give you an extremely detailed breakdown.


If you notice some abnormalities, you should first try reinstalling the problem application to see if it corrects the issue. If the problem persists in any way, you should try uninstalling it (if you can) to see if that has a positive effect on your phone’s battery life.

If you think an app is causing an issue and you can’t figure out which it is, you’ll want to boot your device into Safe Mode so that you can single out the perpetrator.

Booting the device into Safe Mode will disable your phone’s third-party apps. If your battery starts draining with Safe Mode enabled, then you know it’s not your apps causing the problem.

Here’s how to boot the Galaxy S6 into Safe Mode:

  1. Power down the device. Then, press & hold the power button and volume down key.
  2. Once it boots up, you can let go of the power button but keep the volume key held down.
  3. When you have successfully entered into Safe Mode, you will notice the text ‘Safe Mode’ at the bottom left corner of the screen.

Here’s how to boot the Galaxy S5 into Safe Mode:

  1. Power the Galaxy S5 down. Then, press & hold the power button and volume down key.
  2. Once the phone boots, you can let go of the power button but keep the volume key held down.
  3. When you have successfully entered into Safe Mode, you will notice the text ‘Safe Mode’ at the bottom left corner of the screen.

Restart Your Device & Do It Regularly

If you’ve finished digging into your phone’s apps and you can’t isolate the problem, it’s time to take some more steps to improve your Galaxy Android 5.1.1 battery life.

The first thing we recommend doing is restarting your phone. Hold the power button on the Galaxy S6, Galaxy S6 Edge or Galaxy S5 and wait for it to completely turn off. This will clear the cache.

Once that’s done, turn the phone back on. This sometimes has a positive effect on battery life and we recommend restarting your phone regularly.

Kill Unnecessary Services

If you can’t nail down a rogue application or if a simple restart fails to improve your Android 5.1.1 battery life, you probably want to start monitoring the different services on your phone.

If you get into the habit of disabling features that you’re not using on your phone, you might be able to secure some extra juice. We recommend turning off GPS when you’re not using it. We also recommend shutting off Wi-Fi, Bluetooth, LTE, and NFC when you don’t need them.


We are constantly manually all of these and you can turn most of these off using TouchWiz’s Quick Settings function that allows you to swipe down and easily toggle off the phone’s most important connections. Use Quick Settings and use it often.

If you’re lazy or you’re in an area with horrible service, you might want to flip on Airplane Mode. Airplane Mode will disable all of these connections. This is a useful feature when you’re in an area with spotty service. If your phone is constantly checking for a connection, be it cellular or something else, it could drain your battery.

Use a Black Wallpaper

If you’re looking to save some battery life, you should stop using live wallpapers. These have been known to suck up battery life on Galaxy phones. Furthermore, you might want to think about using a black wallpaper on your Galaxy S6, Galaxy S6 Edge, Galaxy S5, or whatever you’re using for a phone.

Switching to a solid black wallpaper could help deliver better Android 5.1.1 battery life thanks to the way Samsung’s beautiful AMOLED displays consume power.

Samsung’s devices do not come with a default black wallpaper but you should be able to find one online. After you’ve downloaded one to your Galaxy S6 or Galaxy S6 Edge, go to Settings -> Personal -> Wallpaper -> From Gallery -> and then set your black Galaxy S6 wallpaper.

If you own a Galaxy S5, head to Settings -> Wallpaper -> Home and Lock Screens -> More Images -> set your black Galaxy S5 wallpaper.

Start Using Software Features

The Galaxy S6, Galaxy S6 Edge, Galaxy S5, and Samsung’s other Galaxy smartphones come with built-in battery saving features that you should start using to save battery life on your phone.

One of the features is called Power saving mode. The other is called Ultra power saving mode. If you’re using a Galaxy S6 or Galaxy S6 Edge, you’ll find them both in Settings. Slide over to System and then to Battery and both features will be listed at the top.


These features are extremely useful because they allow you to block background data, turn on a grayscale mode that helps limit the amount of battery life being sucked up, slow down the processor, reduce screen performance, turn off the lights on the buttons, and turn off GPS to save battery life.

Start using these with regularity, even if you aren’t noticing major battery issues with Android 5.1.1. They will help you in crucial situations where you might need an extra few minutes with your phone.

Replace the Stock Launcher

If you aren’t in love with the stock TouchWiz launcher, you can replace it with something else. That something else will deliver a different look and it also could deliver better performance.


There are tons of different launchers on the Google Play Store though the Nova Launcher is one of Android’s most popular choices. It’s worth a shot if you aren’t able to figure out what’s causing the performance problems on your phone.

Look Into Downgrading

If you own a Galaxy S5 or another phone that was bumped from Android 4.4 KitKat to Android Lollipop and you are convinced that it’s Lollipop causing the battery life issues on your phone, you might want to look into the downgrade process.

A Galaxy S5 owner put together a solid guide on the process in the aftermath of the Android Lollipop upgrade and there should be a lot of other reading out there. It’s not an easy process but it’s a step that you might want to consider if you’re alright with rooting your phone.

Factory Reset Your Device

If you can’t figure it out and you don’t want to send in your phone to a carrier or Samsung, you can try factoring resetting your phone to see if that returns things to normal. This should only be performed as a last resort and you’ll want to back up all of your important files before making the move.

To factory reset the Samsung Galaxy S6 or Galaxy S6 Edge, go into Settings -> Personal -> Backup and reset. From there, select Factory Data Reset. From there, select Reset Device. This is an involved process and it will take some time so you’ll need to remain patient.


If you own a Galaxy S5, go into Settings, User & Backup, and select Backup and Reset. From there, select Factory Data Reset. From there, select Reset Device and then Delete All. Same thing. It will take awhile to complete so you’ll need to hang in there while the device does its thing.

Buy a Battery Pack

If you’ve tried it all, including a factory reset, there are a few other options. You can get in communication with Samsung. You can contact your carrier and see if you can secure a replacement. Or you can replace your battery and/or buy an extended battery or battery pack for your phone.

If you own a Galaxy S5, you can replace the battery yourself. You can buy a stock battery from Samsung to see if that works or you can buy an extended battery if you want a little more juice.

The Galaxy S6 and Galaxy S6 Edge do not come with a removable battery so you’ll need to take a look at battery packs, not batteries themselves.

If you’re willing to pay money to improve battery life Android 5.1.1, Mophie’s got a Juice pack available for the Galaxy S6. Mophie makes top notch battery cases and they’re worth a look if you are in need of a case and improved battery life.
