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.

I face the same isssue. My battery was able to last 2 days with no problem. With Android11 it lasts only 1 day. Is there any solution? Factory reset helps?

I was draining about 10% overnight but it has dropped to 1-2% after factory reset.

Yeah i also did a factory reset therefore discharge due to standby time decreased but still the battery is draining faster hope it will improve by future updates

Facing the same issue here. Was using the beta version earlier and the phone was functioning fine.
Did a factory reset when the final build was launched and the battery drain is present ever since.
Guess an update is required to reduce the Android System battery drain.
