Problem: Galaxy S9 battery drain issue due to AASAservice

i use a Galaxy S9 samsung. i just installed new android update on 2nd december. Since then my battery started draining fast. I had to charge thrice in a day since then. I have switched on and off using the volume key +bixby key power key and did what has been advised to do. But it didn’t work out.  

Secondly, I found some AASA service to be using most of the battery power. But the disable button is not highlighted ( enabled). I could only force stop. I don’t know whether this is the exact reason but some respite after force stop. However, some time later the draining of battery continues.  The screen resolution, Always on display etc etc are being used before new update installation also. So, suggesting those wouldn’t help to resolve the actual problem. Thirdly, My SMS app is auto shutting in the middle of messaging and screen returns to home screen. what’s the problem? please help me out.

Solution: AASAservice is one of the many core services needed to provide the distinct Samsung experience on Galaxy devices. In general, it shouldn’t top the list of apps and services that consumes the battery under Battery Usage. If AASAservice on your device appears to have been the leading reasons for battery drain, or if there’s significant difference in battery use after an update, these are the troubleshooting steps that you can try:

Clear the cache partition

Sometimes, your device’s system cache, which is used by Android to load apps quickly, may become corrupted an update. If this happens, some apps may not work properly, crash, or becomes slow. If several apps are affected by a bad cache, there may be a system-wide slowdown, which, in turn, can lead to longer loading times and inefficient functioning. To ensure that the system cache is in good shape, be sure to clear the cache partition regularly. Here’s how:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Forced restart

Sometimes, this simple procedure can fix bugs that developed after the system has run for a long time. By manually forcing your S9 to reboot, you’re basically simulating a battery pull, which, in older mobiles with removable battery packs, was an effective way to refresh the system. If you haven’t tried this one yet, here are the steps that you can do:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.

Install app updates

Some apps may develop bugs or become problematic after a major Android update. Be sure that all the apps you installed are compatible with the current OS version to avoid encountering problems with them. App publishers want to minimize incompatibility issues with Android as much as possible but some apps may not receive the same amount of care or maintenance. As an end user, the most that you can do is to install updates. Do what you can.

Calibrate the battery

Sometimes, Android may lose track of the actual battery levels. To recalibrate the operating system so that it gets accurate battery level readings, do the following:

  1. Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.
  2. Charge the phone until it reaches 100%. Be sure to use original charging equipment for your device and let it charge up completely. Do not unplug your device for at least two more hours and also don’t use it while charging.
  3. After the elapsed time, unplug your device.
  4. Restart the device.
  5. Use your phone until it completely runs out of power again.
  6. Repeat steps 1-5.

Clear app preferences

Some apps require default or core apps and services to work properly. Sometimes, updates may inadvertently interfere with Android and disable important system apps. To rectify the situation, make sure that you reset all app preferences to their defaults first. Here’s how:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Reset app preferences.
  5. Restart your S9 and check for the problem.

Reset all settings

This procedure is separate from the previous one as it covers all settings of your Android device and not just the apps. To do this, follow the steps below:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management > Reset settings.
  3. Tap Reset settings.
  4. If you have set up a PIN, enter it.
  5. Tap Reset settings. Once complete a confirmation window will appear.

Factory reset

One of the effective ways to fix battery drain issue after an update is factory reset. If AASAservice continues to be on the top of the list for apps that contributes to the problem, wipe the phone by doing a factory reset.

  1. Create a backup of your data.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Other potential solutions to battery drain

Lower screen brightness. Dimming the screen is a good, simple way to prolong battery life day in and day out. Decrease screen brightness to the lowest comfortable level for you and leave it at that.

Uninstall apps. The more apps you install, the higher the chance of problems or battery drain to occur. Get rid of apps you haven’t used in the last two weeks. If you did not use them for that long at this time, chances are they’re not important to you or to your lifestyle. Delete them to clear up space and lower the possibility of encountering problems with them. You can always install them anyway if you want in the future.

Kill apps you don’t use. Use the unmonitored and always sleeping apps function from Settings > Device maintenance > Battery > Unmonitored apps. you should have no apps in there (delete if anything’s there). Use the Always sleeping apps function and put all apps in there that you won’t need push notifications for.

Optimize.  Go to Settings > Device maintenance > Let it load and click Optimize Now.
