How to Fix Bad Galaxy Note 4 Battery Life After Lollipop

The Samsung Galaxy Note 4 Lollipop update delivers new fixes, new features, and new enhancements for Samsung’s current Galaxy Note flagship. According to Galaxy Note 4 owners, it also brings battery life problems along with it. With that in mind, we want to take an in-depth look at how to potentially fix bad Galaxy Note 4 battery life before and after Android 5.0 Lollipop.

In September, Samsung took the curtain down from around its Galaxy Note 4, a replacement for the Galaxy Note 3. As expected, the Samsung Galaxy Note 4 arrived with all sorts of bells and whistles including a new design, an improved display, a solid camera, and Android 4.4.4 Kitkat. At the time, Android 4.4.4 KitKat was the most current version of Google’s mobile operating system.

Given the Galaxy Note 4’s status as a flagship, it was no surprise that it found itself among the first Samsung Galaxy smartphones to Google’s new mobile OS, Android 5.0 Lollipop. The Galaxy Note 4 Lollipop update started rolling out last month and it delivers some big time features to Galaxy Note 4 users. Some have already gotten a taste of the changes, others are still waiting for the update to start rolling out.


While the Galaxy Note 4 Lollipop update brings some huge changes to the device, it also brings Android 5.0 Lollipop problems including battery life issues. Complaints about bad Galaxy Note 4 battery life have started to pick up as the software’s moved out to more variants and more regions around the world including the United States where it’s now available on Sprint.

Battery life issues always seem to plague Galaxy users after a new Android update though most of the time, it’s not the actual update that’s causing the problems. Apps and other services are usually the culprit. For the moment, these Galaxy Note 4 battery life problems appear to be somewhat isolated though we do expect them to grow as more updates roll out.

How to Fix Bad Galaxy Note 4 Battery Life

With that in mind, we want to try and fix bad Samsung Galaxy Note 4 battery life for you. 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 5.0 Lollipop. We’ve geared this towards Android 5.0 Lollipop users but we know that plenty of people remain on the older version of Google’s software.

Find Apps Eating Up Your Battery

The first recommendation that we always make to people suffering from bad battery life is for them to check out third-party applications. Some people listen, some don’t. If you want to fix your bad Galaxy Note 4 battery life, you’re going to want to keep an eye on applications for potential problems.

Third-party apps have a tendency to put a huge dent into the battery life on the Galaxy Note 4 or any other smartphone, regardless of the software that’s running on board. 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.


Head into your settings and start taking a look at the effect that Galaxy Note 4 applications are having on the device’s battery life. If you notice anything 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 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 Note 4 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 Note 4 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 Note 4

If you haven’t restarted your Galaxy Note 4 in awhile, now is a great time to perform a simple restart. This will clear the device’s cache and perhaps, solve some of the battery life problems that you’ve been seeing. Most of you know how to restart the Galaxy Note 4 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 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.

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 Note 4’s settings and the device’s quick menu makes this even easier.


One thing that we’ve noticed is that poor cellular coverage is often to blame for bad Android battery life. When your Galaxy Note 4 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.

Try Using a Black Wallpaper

Switching to a black wallpaper could help deliver better Galaxy Note 4 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. 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 Note 4 wallpaper. It’s a quick fix but it could certainly help.

Start Using the Device’s Built-in Features

Right now is a great time to start using the Galaxy Note 4’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 Note 4 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 Galaxy Note 4’s brightness slider. The Galaxy Note 4’s powerful display 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 Note 4 battery life. If auto-brightness isn’t working out, try doing it manually.

Replace the Stock Launcher

You also might want to consider replacing the stock TouchWiz launcher on the Samsung Galaxy Note 4 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. Give that a try if these other simple fixes don’t work out.

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 wanted. 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.

Factory Reset the Galaxy Note 4

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 Note 4. 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 Note 4, 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 Note 4 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 Note 4 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 this 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.
