Android 11 is draining the battery

[jaibalaji2020]

Model Name: Asus 6z (Zenfone 6)
Firmware Version: WW_18.0610.2101.127
Rooted or not: not
Frequency of Occurrence: daily
APP Name & APP Version (If your issue relates to the app):
========================================
Ever since I upgraded to Android 11 the battery is draining very fast. Android System takes up too much battery. I used to get more than 10 hours Screen on Time before and now I get barely 5 hours. I'm also on Power Saving Mode.

The same here. The phone was fine until last update .127. Now Android System is draining almost all battery in few hours.

The phone was charged until 90% and used for less than 1 hour. After 4 hours the Android System drained a lot of the battery.

1.Charge it to 100% once and overcharge it for 20-25 min or leave it plugged in with scheduled charging for the night
See if that improves your sot
2. Else try following these recalibration steps

3. If the above steps don't help you can lastly try an factory reset
Just an FYI check if any rogue application is draining battery in the background

Dear Averan,
I think the people write here are experienced users and use this channel as last resource. All you wrote here are of no benefit. The phone was fine after the Android 11 update and after the update .127 one week ago it is a fierce battery consumer. The Android System is consuming a lot now and it is not related to any application. Some Asus services are draining a lot of power now.
Yesterday I rolled back to Android 10 and now, after 6 hours of use, Android System has drained only 2% from the battery, not 30% like Android 11.

I confirm, android 11 destroys the battery, hey moderators need an update because it uses up the battery too quickly
