Battery drain on 8 series via OnePlus Community App

  1. Kurban Ali , via OnePlus Community App , Oct 29, 2020 :
    After Android 11 update, the battery of OnePlus 8 drains very fast and that too without AOD. The SOT has reduced considerably and battery drain during standby and at night is also very high.

    Please solve this issue.

    Have you checked battery stats? (both pages)

    Does anything look unrealistic compared to actual usage?

    You might want to try some additional tools. The more you know the easier to remove the problem or point in the right direction (App Dev, OS dev, need of changes in settings and so on).

    You can force manual background optimizing and view the actual CPU usage via ADB.
    Background optimizing (adb shell) : cmd package bg-dexopt-job
    CPU usage (adb shell) : top -m 10 (or a other number of your choosing).
