Pinterest LinkedIn Tumblr

After the release of the new Android 13 update to Samsung’s current flagship, Galaxy S22 devices, users have reported the device has a severe battery draining issue.

According to some users and their reports, the device’s battery efficiency has dropped by almost 50% percent. That means, if the Galaxy S22 lasted 12 hours before the Android 13 update, it now lasts only 6 hours, for most users.

the battery drains mostly because of a bug or an increase in resource usage of your Galaxy S22. We all know Android 13 brought new features and a pleasing UI. It all somehow costs the device’s resources and, more importantly, the battery.

The other reason why the battery drains so much of your Galaxy S22 is third-party apps that are not yet optimized for the new Android 13 update.

But you don’t have to worry about this anymore. We did an investigation about this issue on various platforms and found actually working solutions that can fix this problem.

Note: Solutions in this guide will work on any Samsung Galaxy S22 model (S22, S22 Plus, S22 Fe, and S22 Ultra models.)

Editor’s note: We created these instructions using a Samsung Galaxy S22 running Android 13. Depending on your device’s software version, some steps and menu positions may look slightly different.

Fix 01 – Check Which Services and Third-Party Apps Causing Battery Drain 

Some apps and services (even the least important ones) may keep running in the background of your Galaxy S22 and cause battery draining.

You have to check the battery usage of your device and see which apps and services use most of the battery power.

Then if there is a third-party app that eats up the battery, you can reduce the app’s background activity or remove it completely from your device if you don’t need it.

That way, you can increase the battery performance of your device. So here are the steps you need to follow;

  1. Open Settings.
  2. Tap on Device care.
  3. Tap on Battery.
  4. Go to battery usage and see if there is any unwanted service/app that has a heavy battery usage.
Battery usage by apps

Once you identify which app/s is causing battery draining, follow these steps to reduce their background activity.

  1. On the same window, tap on an app that has heavy battery usage.
  2. Tap on “Limit usage.”
  3. Tap on “put to sleep.”
Put power hungry app to sleep

Once you do the same for every app that consumes a lot of battery power, restart your Galaxy S22 and see if the solution made a difference.

Fix 02 – Clear System Cache

It is usually recommended to clear the system cache after installing a software update. The reason is, the previous cache of your Galaxy S22 is built by the older system software (Android 12). So the new software update may not work well with the previously built cache.

Clearing the system cache won’t affect your personal data; it only clears cached data in the cache partition (the cache partition is in a separate area and your personal data won’t get stored there). So this is a safe solution to do.

To clear the system cache, you have to boot your Galaxy S22 to recovery mode. If you don’t know, here is how;

  1. Turn off your Galaxy S22
  2. Plug a USB cable into your device and plug the other end of the cable into a power source (a charger, a Laptop, etc)
  3. Press and hold the volume up key for a few seconds and your device should boot into the recovery mode

Note: If pressing the volume up button doesn’t work, press and hold the power button and the volume up button together. Then release the keys once your device boots into the recovery mode (you will see a black background and a white text menu)

  1. Now, press the volume button and select “Wipe cache partition”
  2. Then, press the power button
Wipe cache partition
  1. You will be asked to confirm the command, select yes and press the power button
Confirm wipe cache
  1. Clearing the cache will be completed within seconds. Then, you will see the recovery menu again. Tap on the power button by selecting “Reboot device now,” and your Galaxy S22 will restart to normal mode

Fix 03 – Turn Off “RAM Plus” Feature

If you don’t know, the RAM Plus feature uses your Galaxy S22 device’s storage to create a virtual memory that can help to increase the device’s overall performance.

However, some users have reported disabling this feature helped them to increase the ruined battery performance of their devices after the Android 13 update.

So this solution is worth giving a try. Let’s see how you can do this too;

  1. Open Settings.
  2. Tap on Device Care.
  3. Tap on the Memory section.
  4. At the bottom of the windows, you will see the RAM Plus feature. Tap on it.
  5. Now toggle off the feature.
  6. Restart your device after turning off the RAM Plus.

After restarting the device, you will see the battery performance has been increased on your Galaxy S22.

Fix 04 – Factory data reset

If you want to increase the battery performance and reduce the draining of the battery further, you can do a factory data reset on your Galaxy S22.

Please note that we cannot ensure doing this will significantly increase the battery performance. However, according to our tests and based on user reports on this problem, this solution has worked most of the time.

If you want to factory data reset to your Galaxy S22, follow these steps;

  1. Open Settings.
  2. Tap on General management.
  3. Tap on Reset.
Reset option samsung
  1. Then, tap on “Factory data reset”.
Factory data reset
  1. Enter the screen lock password and confirm.

It will take some time to restart your Galaxy S22. Once the reset is completed. The device will restart automatically. There you can set up the device by entering your email address and password.
