    There's a considerable and consistent fast battery drain and a problem of degraded battery life in the OS This problem wasn't present in the previous OS 10.3.8 build.

    Even after several charge cycles, the battery drain is unusually extremely high and this never happened before.

    Using mobile data and talking over calls lead to a faster drain and the SOT has also gone down by 20% or more.

    Please look into this matter asap and please send in another hotfix update only for this inferior battery life.

    Thank you.

    Any updates on this? Would it be possible to revert back to the previous build? This build is draining CONSIDERABLE amount of battery when the phone is not in use and it's completely unacceptable, I went from charging the phone once a day now to 3 times a day.

    EDIT: Potential fix, wipe cache by accessing the wipe cache and data menu.

    After android 11 update battery backup reduce tremendously I used to get 5-6 hr sot with 24hr use now I need to charge my device twice daily which is very unfortunate i am only getting 3hr sot that too in 8-10hr standby time which is very very unfortunate i wish i wouldn't have upgraded the phone I request oneplus to solve the issue as soon as possible as it's there since a month and more but still no solution or else we need to switch to another brand which take care of their customer.

    Their are many complaints regarding android 11 update and battery issue but oneplus is not taking care of them.

    Same with mine: fast charge not recognized by the phone and unusual battery drain. This occurs much more evidently while using the phone rather than in standby

    This is the strategy of oneplus.
    Older versions are getting free battery replaced.

    But when you spend 50k you didnt get any free battery upgrade.

    OS updates makes battery draining fast.

    Recently i have updated phone with new battery at service center by paying 2599 Rs.

    Official rate is 1300 but oneplus charges alot.

    Anyways but the issue is same.
    Oneplus service guy also confirm that its company strategies for older device to act wierd.
