How to Fix One UI 6 Battery Drain Issue on Samsung Galaxy Phone? 

The latest version of Samsung’s Android skin, One UI 6, is slowly making its way to devices. Based on Android 14, the update brings many new features and improvements. However, it also seems to have introduced a new battery drain issue on some Galaxy phones.

If you’re experiencing excessive battery drain after updating to One UI 6, you can try a few things to fix the issue.

12 Ways to Fix One UI 6 Battery Drain Issue

As smartphone usage has increased, so has the number of ways we use them. We now use our devices for everything from entertainment and communication to work and managing our lives. With all these different tasks, it’s not surprising that a smartphone’s battery life has become essential. This brings us to the gravity of the One UI 6 battery drain issue.

You’re not alone if you’ve noticed worse battery life on your Samsung Galaxy phone since updating to One UI 6. Several users have taken to Twitter, Reddit, Samsung Community, and other platforms to complain about battery drain issues after upgrading to the latest version of Samsung’s custom Android skin.

Several Redditors and Samsung Community users have reported that their phones are losing battery much faster than before.

My S22 Plus just updated to One UI 6, and the battery has drained faster since then.

On One UI 5, I used to get an estimated 23 hours 45 minutes with a full charge. Now, with One UI 6 and Battery Protect on for two weeks, the estimated usage has dropped to 15 hours (and keeps decreasing) even though my usage hasn’t changed.

I have two Z Fold 5s. Both phones experienced significantly faster battery drain after upgrading from One UI 5 to 6.

This makes it evident that this is a concerning issue. Samsung has not yet acknowledged the issue, but the company is likely aware and working on a fix.

In the meantime, you can do a few things to try and improve your battery life.

  1. Turn off the Always On display
  2. Turn on the Power Saving Mode
  3. Turn on Dark Mode
  4. Turn off GPS, Wi-Fi, Bluetooth, Mobile Data, Hotspot
  5. Close power-draining apps
  6. Close any background processes
  7. Turn off automatic synchronization
  8. Adjust your screen brightness
  9. Disable unnecessary notifications
  10. Turn off Haptics and Vibration
  11. Check for software updates
  12. Update you apps

1. Turn off the Always On display

You may have noticed the Always On display feature on your Galaxy phone. This is an excellent feature if you always want to see the time, date, and other information at a glance, but it can be a battery drain if you don’t need it. Here’s how to turn it off.

  1. Open the Settings app and search for Always-On display.
  2. Tap on the first search result.
  3. Please tap on the toggle next to the Always On display to turn it off.

If you still want to have the Always On display without compromising battery life, you can set the Always On display to turn on only when you tap the screen or a new notification pops up. You can schedule the Always On display to turn on during a specific time.

Always On Display is a great feature but can be a battery drain if you don’t need it. You can save battery life by turning it off or customizing the settings.

2. Turn on the Power Saving Mode

You can consider turning on the Power Saving Mode to reduce battery drain in One UI 6. Doing so can help eke out a bit more battery life when you need it.

To turn on Power Saving Mode in One UI, head to Settings > Device maintenance > Battery. From here, you can enable Power Saving Mode or schedule it to turn on automatically at a certain percentage. You can also enable it from the quick settings menu.

When Power Saving Mode is turned on, certain features will be restricted to save power. For example, the Always On display may be turned off, and performance may be reduced. But these trade-offs can be worth it if you need to save battery life.

Enabling Power Saving Mode in One UI can help you save battery life when needed. This feature can surely help fix the battery drain issue to a certain extent.

Turn on the Power Saving Mode

3. Turn on Dark Mode

While there are many ways to help fix the battery drain issue, one under-utilized feature is dark mode. Dark mode is a setting that can be enabled on most phones that changes the phone’s color scheme to darker tones.

Why is dark mode suitable for your battery? The answer has to do with your phone’s screen. You are telling your phone to turn on fewer pixels by turning on dark mode. This means your phone’s battery will last longer because it doesn’t use as much power to light up the screen. So, turn on dark mode, and you should see an improvement in your smartphone’s battery life.

4. Turn off GPS, Wi-Fi, Bluetooth, Mobile Data, Hotspot

GPS can be a huge battery drainer, so turning it off can take out a bit more life from your phone. If you don’t need Wi-Fi or Bluetooth, turn them off. Mobile data is another giant battery hog, so turn it off if you don’t need it. The hotspot feature on your phone can also use up a lot of battery, so if you don’t need it, turn it off.

Turning off these features lets you get more battery life out of your phone. So, if you’re low on battery, turn off these features to save some power.

5. Check for battery-draining apps

One of the first things you should do if you’re experiencing battery drain issues is to check for any apps that may be causing the problem.

When you’re not using an app, it can continue to run in the background and drain your battery. To help conserve battery power, One UI lets you close these apps with a single tap.

To close power-draining apps:

1. Tap the recent apps button or use the gesture to reveal the recent apps.

2. Swipe away the app you want to close.

You can also close multiple apps at once. To do this, tap the ‘Close All’ button to close all the opened apps.

You can also specifically check if any apps are heavily impacting your battery. To do this, go to Settings > Device Maintenance> Battery. Here, you’ll see a list of all the battery power apps. If you see any apps using an unusually high amount of battery, try removing them and see if that helps.

6. Close any background processes

Background processes such as background downloads, syncing, and file uploads can also adversely hurt your smartphone’s battery. So, make sure you close all background processes when not needed. One UI 6 also makes it easier to check on background processes and kill them immediately.

To close background processes in One UI 6:

  1. Tap the recent apps button or use the gesture to reveal the recent apps screen.
  2. Tap on “x apps active in the background” on the top-right of the screen, where x is the number of apps active in the background.
  3. A small menu box with a list of currently active apps will appear at the bottom of your screen.
  4. If you don’t need an app to run in the background, tap the “Stop” button to close it.

By closing background processes, you can significantly improve your battery life.

7. Turn off Auto Sync

One UI has an “auto sync” feature, which constantly checks for new emails, social media notifications, and other updates even when you’re not using your phone. This causes the battery to drain faster than you would want.

Fortunately, there’s an easy way to fix this battery drainage issue. All you have to do is turn off auto sync on your phone. Here’s how:

  1. Open the Settings app on your Samsung phone.
  2. Tap on the “Accounts and backup” option. You may not find the exact name, so try to find a similar option in the settings. You can also search “auto sync” using the search bar.
  3. Tap “Manage accounts.”
  4. Turn off the “Auto-sync data” toggle.

That’s it! Once you’ve turned off auto sync, your phone will no longer sync data automatically, and as a result, your battery life will improve.

8. Adjust your screen brightness

Another way to save battery and fix the battery drain issue is by adjusting the screen brightness. You can easily adjust your screen brightness to help save battery.

To adjust your screen brightness, slide down the quick settings menu or the notification panel and drag the brightness slider to adjust the brightness as low as possible. You can also enable the Adaptive Brightness feature, which automatically adjusts your screen brightness based on your surroundings.

9. Disable unnecessary notifications

Notifications can be handy. They can inform you about what’s happening with your apps and let you know when you have a message or something else that needs your attention. However, notifications can also be a huge battery drain. Keeping your battery life up can be challenging if many apps send you notifications.

You can tackle this by disabling the notifications from certain apps or even entirely. When you disable notifications for an app, that app will no longer send you any notifications. This can be a great way to save battery, especially if you have an app you don’t need to be notified about.

To disable notifications for an app, go to Settings > Notifications. You can see a list of all the apps that can send you notifications. To disable notifications for an app, tap on the app and then toggle the “Show Notifications” switch to the off position.

Doing this for all the apps you don’t need to be notified about can help you save a lot of battery.

10. Turn off haptics and vibration

Haptics and vibrations use much battery power, so you must know how to turn them off when you don’t need them. In the One UI 6 settings, you can find the options to turn off vibration under the “Sounds and Vibration” category.

To turn off the vibration, click on the following and drag the intensity slider(s) to the left.

  • Call vibration
  • Notification vibration
  • System vibration
  • Vibration intensity

Make sure also to turn off all the vibration options under System Vibration.

Once you turn off the vibration, you’ll notice a difference in your phone’s battery life. So, the next time you’re worried about your battery dying, turn off haptics and vibration in the One UI settings.

11. Check for software updates

It is always a good idea to check for software updates, which often include bug fixes and performance improvements.

To check for software updates in One UI, go to the Settings app and tap on the “Software update” option. On the next screen, you’ll see whether an update is available. If an update is available, tap on “Download and install,” and you’re done.

12. Update your apps

Make sure to check for updates for your apps regularly. Most app updates include bug fixes and performance improvements that can help save battery. To check for updates on your One UI smartphone, open the Google Play Store app, tap the profile icon, and select My Apps & games.
