How to Fix Bad Galaxy S5 Battery Life After Lollipop

The Samsung Galaxy S5 Lollipop update delivers new features and enhancements to users. But according to many Galaxy S5 users, it also brings battery life problems to the former flagship. With that in mind, we want to take an in-depth look at how to potentially fix your bad Galaxy S5 battery life.

In 2014, Samsung introduced its Galaxy S5, a device that arrived with a number of high-end features including an upgraded design, improved camera, and Android 4.4 KitKat software. The device was considered, by many, to be one of the best phones of the year.

So it was no surprise when the Galaxy S5 became one of the first Galaxy smartphone to receive Android Lollipop. The Lollipop update brought Material Design, a new lock screen and more to the device.



For many Galaxy S5 users, Lollipop has been solid. For others, not so much. Complaints about bad Galaxy S5 battery life were loud at the beginning and we continue to hear complaints about bad Lollipop battery life in 2016.

Battery life issues always seem to plague Galaxy users though most of the time, it’s not the update causing the problems.

Apps and other services are usually the culprit. These Galaxy S5 battery life problems appear to be somewhat isolated though they could appear on your device at any time. With that in mind, we want to try and fix bad Samsung Galaxy S5 battery life for you.

How to Fix Bad Galaxy S5 Battery Life

This guide delivers help to get better battery life on Samsung’s current flagship. These fixes should work if you’re on Android 4.4 KitKat or if you’re on Android Lollipop. Most Galaxy S5 users, at this point, should be on Android 5.1.1.

These fixes should hold you over until Samsung and its carrier partners get around to updating the Galaxy S5 with Marshmallow.

Find Apps Eating Up Your Battery

The first recommendation that we always make is to check out your third-party applications. If you want to fix your bad Galaxy S5 battery life, you’re going to want to keep an eye on applications for potential problems.

Third-party applications have a tendency to put a huge dent into the battery life on the Galaxy S5, regardless of the software that’s currently running. If you use an application a lot, it’s going to drain your battery.

There are also times where bugs or issues might cause an app to go rogue and start abnormally draining the device’s precious battery life.

Head into your settings and start taking a look at the effect that some of your applications are having on your device’s battery life. 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 to see if that has a positive effect.

If you can’t figure out which app might be causing trouble, you’ll want to boot the Galaxy S5 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 S5 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.

Restart the Samsung Galaxy S5

If you start noticing weird battery drain and or your device starts heating up, you should try performing a simple reset to see if that returns things to normal.

Most of you know how to restart the Galaxy S5 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 issue, it’s time to start 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 Galaxy S5’s settings.


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, so 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.

Other connections that are constantly working in the background can be a negative influence on battery life. Start toggling features off when you don’t need them. The gains might not be massive but you should start to see a positive impact.

Start Using a Black Wallpaper

Switching to a black Samsung Galaxy S5 wallpaper can help deliver better Galaxy S5 battery life thanks to the way the Super AMOLED display on the Galaxy S5 consumes 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 -> Wallpaper -> Home and Lock Screens -> More Images -> set your black Galaxy S5 wallpaper.

Start Using the Device’s Built-in Features

You’ll also want to start using the Galaxy S5’s built-in battery saving features. Power Saving Mode is a good place to start, and Ultra Power Saving mode is an even better option when you need the Galaxy S5 battery to last longer than normal.

These features allow you to block background data and turn on grayscale mode which can help to limit the amount of juice being sucked up. You can also slow down the processor, reduce screen performance, turn off the lights on the buttons, and turn off GPS to save battery life.


We also recommend getting familiar with the the brightness slider. The screen can suck up a ton of battery life so you’ll want to monitor the brightness of the screen if you’re starting to notice bad Galaxy S5 battery life.

Replace Your Launcher

If none of these fixes work, there are three other drastic solutions to try. The first is to replace the TouchWiz launcher on the Galaxy S5.

The TouchWiz launcher has been known to hinder performance and it can be replaced. There are tons of different launches to choose from though the Nova Launcher is one of Android’s most popular choices.

Downgrade to Android 4.4 KitKat

If that doesn’t work, you could try downgrading to Android 4.4 KitKat. A Verizon Galaxy S5 user recently put together a step-by-step process on how to move back from Android 5.0 Lollipop and those interested can find the instructions here.

This isn’t guaranteed to fix your issues but it’s worth a shot if you don’t want to wipe the device or if none of these fixes have an impact.

Factory Reset the Galaxy S5

If you don’t want to downgrade to Android 4.4 KitKat and you can’t find any fixes for your battery problems, you can factory reset your Galaxy S5. This will wipe all of your files so you’ll need to make a backup before going this route.

To factory reset the Samsung 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.

If for whatever reason that doesn’t work, users can also factory reset using the hardware keys on the phone. Here’s how to do that. It’s a far more difficult process. We recommend the above route if possible.

  • First, you’ll need to turn the Galaxy S5 off.
  • Once its off, press and hold the Volume up button, the Home button, and the Power buttons together until you see an Android appear on the screen.
  • Once you see this, use the Volume down key to highlight the Wipe Data/Factory Reset option. Use the Power button to select it.
  • Use the Volume down key to select Yes – delete all user data and then use the Power button again to select it.
  • When you see the Reboot System Now option, you’ll know you’re on track. Use the Power button to select that option.
  • This will erase everything on the Galaxy S5 bringing it back to the state it was in when you first bought it. It also might fix the problems you’re having.

We’ve heard from several Galaxy S5 users who say that this fixed bad battery life on Lollipop though it should be considered a last ditch effort. It’s an extremely time consuming process.

If nothing here works, contact Samsung or your carrier. If you’re under warranty, you might be able to get a replacement.
