How to Fix Bad Galaxy S4 Battery Life After Lollipop

The Samsung Galaxy S4 Android Lollipop update brings a ton of new features to the company’s former flagship but it also brings battery life problems. With that in mind, we want to take a look at how you can potentially fix bad Galaxy S4 battery life.

When Samsung first announced the Galaxy S4 back in 2012, the company confirmed that it would have Android Jelly Bean on board. At the time, Android 4.1 Jelly Bean was Google’s current version of Android.

Over the years, Samsung’s outfit the Galaxy S4 with a number of new software updates including Android 4.3, Android 4.4 KitKat and the Android 5 Lollipop update.

The Galaxy S4 Lollipop update delivered some big time features to owners of the aging former flagship including Google’s new Material Design. It’s also, believe it or not still causing problems for many people who’ve hung onto this fossil of a phone.


Galaxy S4 users continue to complain about battery life issues. Battery life issues always seem to plague Galaxy users after a new Android update though it’s usually not the update itself causing the problems. Apps, services and bad habits are typically the culprit.

These Galaxy S4 battery life problems are isolated but they could appear on your device at any time. And that’s why we want to try and fix bad Samsung Galaxy S4 battery life for you.

How to Fix Bad Galaxy S4 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 S4 users are now on Android 5.1.1.

The Galaxy S4 won’t be getting Android Marshmallow so you’ll need to rely on manual fixes to solve your battery life woes.

Find Apps Eating Up Your Battery Life

The first recommendation that we always make to people suffering from bad battery life is to check out third-party applications. If you want to fix your bad Galaxy S4 battery life, you’re going to want to keep an eye on applications for potential problems.

If you use an application a lot, it’s going to drain your battery. Most of you already know that. However, there are also times where bugs or issues might cause an app to go rogue and start abnormally draining the device’s charge. That could be happening on your device.


The first thing you’ll want to do is head into your settings to take a look at the effect your applications are having on the device’s battery life. If you notice something out of the ordinary, it’s time to start taking a closer look.

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 the app to see if that has a positive effect on battery life. It has for us in the past.

If you can’t figure out which app is causing trouble, you’ll want to boot the Galaxy S4 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 S4 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 Galaxy S4

This is a simple fix but it could prove to be effective. If you haven’t done it in awhile, restart the Samsung Galaxy S4.

Most of you know how to restart the Galaxy S4 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, and a simple restart of the Galaxy S4 doesn’t solve the problem, it’s time to dig a little deeper.

In our experience, disabling features when they aren’t in use tends to have a positive impact on overall battery life.


If you think your Galaxy S4 battery life is draining faster than normal, we recommend shutting off Wi-Fi Bluetooth, NFC, GPS and/or cellular data when you don’t them. You can turn all of those off from inside the Galaxy S4’s settings and the device’s quick menu makes them even easier to monitor.

One other thing to note. Poor cellular coverage is often to blame for bad Android battery life. When your S4  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 should consider turning Airplane Mode on when there isn’t a strong 4G or LTE signal in the area. This could help keep battery drain to a minimum as well.

Try Using a Black Wallpaper

Switching to a black wallpaper could help deliver better Galaxy S4 battery life thanks to the way Samsung’s Super AMOLED displays consume power. The device does not come with a default black wallpaper but you can search online for one.

After you’ve downloaded one, go to Settings -> Wallpaper -> Home and Lock Screens -> More Images -> set your black Galaxy S4 wallpaper. It’s a quick fix but it could help maintain a better charge on your aging former flagship.

Replace the Stock Launcher

You also might want to consider replacing the Galaxy S4’s stock TouchWiz launcher with something new. 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 and one that we continue to recommend to Galaxy S4 users.

Downgrade to Android 4.4 KitKat

If you’ve already moved to Android 5.0 Lollipop, and some of you have, note that you can return to Android 4.4 KitKat in the event that Android 5.0 isn’t on par with what you expected from Samsung’s new update for the Galaxy S4.


We recently put together a guide on how to accomplish this so that’s going to be a great starting point for those of you that want to drop back down to Android 4.4.

Follow those steps using the correct files and you should be able to get Android 4.4 KitKat up and running in no time at all.

Factory Reset the Galaxy S4

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 S4. Note that 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 S4, 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, you 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 S4 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 S4 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 smartphone users who say that a factory reset fixed bad battery life on Lollipop though it should be considered a last ditch effort. It’s an extremely time consuming process but it’s one that could potentially solve your problems once and for all.

If that doesn’t help, it’s probably time to look into your warranty. You’ll want to contact Samsung or your carrier directly to see if they can be of any assistance. In some cases, they might be able to help.
