    Same here bro. I have OnePlus 8 pro and the moment I updated to oxygenos11, I felt quite a difference. Now I hardly get even 15 hrs of full charge time and 2-3 hrs of SOT. Earlier I was easily getting like 24+ hrs with 6-7hrs of SOT.... Pls OnePlus release some new patch as it just makes the device almost unusable.....

    Some info and tools that might help in figuring this out. In my case on beta 2 it's awsome.

    Background optimizing (adb shell) : cmd package bg-dexopt-job
    CPU usage (adb shell) : top -m 10 (or a other number of your choosing).

    A factory reset and clean install is often recommended when doing major version upgrades. 0

    Are you facing this issue regularly?

    Could be some software using the CPU massively thus creating the heat. Check for issues in battery stats.
    If it's not some software creating the heat you may have a faulty device.
    Know a guy that got his 7 Pro replaced. It overheated constantly. The replacement did not.

    Factory reset didnt work, only thing that worked for me is to downgrade to OS 10.

    It seems like we have a few issues. For some it goes away after some time though. Some user got high CPU usage by the process "logd" for example. The CPU command may help in seeing the processes triggering the high drain.

    There is a significant change in battery life after installing oxygen OS 11, I'm hardly getting 4-5 hours of screen on time which was earlier around 7-8 hours. There is bit lag in gaming too.
