    Snap some screenshots of these 2 batterystats. Also mention the screen time.

    If you don't see anything obvious you could also investigate stuff further by looking at the actual CPU usage via adb shell.

    CPU usage (adb shell) : top -m 10 (or a other number of your choosing).

    A other useful command enforces the automatic background optimizing normally done when charged to 100% and left connected and not used long enough.

    Background optimizing (adb shell) : cmd package bg-dexopt-job

    Adb installation.

    Hi, I've deleted the email you shared here. The truth is that this is a public place and you are mostly talking with fellow users, so private info like emails shouldn't be shared here.

    Hope you understand.

    Has for issue you refer regarding the battery, you mean after 5 hours of actual use with the screen on?

    the first battery screen will show your exact active use time since last full charge. regardless of gaming or not active use will use the battery.

    Personally I think apps like this is more helpful when it comes to monitor battery.

    Also adding some guide that used BetterBatteryStats to view and analyse.

    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).
