    Is anyone having similar issues with HTC 10 after update. Android OS and Android System are using 44% and 26% of battery, respectively.

    I'm getting about half the battery life that i used to prior to the update

    Welcome to the forums. Have you tried a cache clear in recovery?

    Apologies for delayed response. Yes cleared clache. Also reset app preferences.

    The issue went away for a day or so but now popped up again.

    Same here. I am doing nothing, but the battery keeps discharging... When I checked in the system both Android OS and system consume a lot battery. Reset and double-wiped my cell twice, no improvement. Did battery test, my battery seems good. Want to downgrade to Marshmallow, but don't know how...

    Back up all important data you may have and preform a factory data reset. When doing a major update to a new OS, wiping system cache partition doesn't always cut it, and a factory data reset using the newly updated recovery img is needed.

    I had done it already... No significant improvement...

    try using it in safe mode or as stock without adding any apps. then gradually add 3rd party apps a few at a time and see if that makes a difference.

    Ran safe mode too... Everything was just fine... Third party apps are not issues because they were what I installed in my phone before the upgrade. After upgrade, Android OS and Android system consume significant my battery, and my phone is always awake.

    Only other thing I could think of if is that perhaps one of the apps isn't playing nice with Nougat. Sorry I can't be more helpful. I am out of ideas. BTW welcome to the forums.

    Thanks for your help and welcoming.

    I post 2 snapshots to share my battery status.

    The battery was full charged when I went to bed. When I waked up it became only 83%. Most battery consumers are Google play service, Android OS, Phone idle ("! why phone idle needs to consume battery ??") and Android system. I did not active any apps when I went to bed, not sure why they consume my battery that much...

    I learned if I have too many apps on my phone desktop, it may consume more battery. So I remove all of them from the desktop and to see if the situation can be improved...

    I've found a solution of my own.. not a complicated one actually. Still testing but it seems it's working out: i've switched to the Sense Launcher (was using the Google Now one) played a bit with some settings on the Boost+ app and of course i'm using the Battery Saving Mode all the time (just kept the vibration on the keyboard).
    It's working well for now.. let you know if this really helps. Cheers

    I haven't played much around the problem.
    I made a reset to the phone, and it's going great again.

    Hello guys,
    Did someone find a fix? I am having quite a similar issue, android OS and Android system are always consuming around 35% of my battery together. Now my phone barely lasts a day even if I don't use it a lot. I tried to reset my phone several times, I also tried to reinstall all apps manually but still, nothing works. No other app seems to be overconsuming the battery, and battery saving mode does nothing. I really love this phone but this really starts to be a problem...

    I'd just like to add another example to this thread -

    OS Android and Android system are using 34/18% of my battery respectively and a factory reset and clearing the cache have failed to improve things. I'd estimate my battery is draining 50% faster than on Marshmallow.

    I would move on to uninstalling all apps and reinstalling them one by one but given it is Android that is draining the battery I don't really see the point.

    I'd really prefer not to have roll back to Marshmallow.

    Same problem. I reset the cache but that didn't do it. I'll try the factory reset.
