Hello guys. I have high battery drain after update. The problem seem that the usage is simply in standby mode, after whole day with 3h screen on time I usually had 50% left, now 12.

As you see in the graph, it is pretty linear.

Any suggestions? I already checked what I could, also len the phone die and fully recharge it.


Thank you

    That does seem very unusual.

    How many days have you updated your phone? I think some have reported that the Android 12 update on some Android devices (e.g. Google Pixel's, Samsung Galaxy's) messes with permissions on things like the camera and keeps them running in the background. It appears that this is one possible cause of the issue, but it might just fix itself after a few days.

    If the problem persists, you might want to wipe the device cache and see what happens.

    If that doesn't work out too, try to back up your data and do a factory reset.

    i have same thing with wifi or mobile data on, looks like something is draining battery while in background, its stupid but just turn off your wifi/mobile data, while you not using phone, i think they must fix it in next patch
