    Thank you H8FKAndroid, it looks like i'm stuck with this for now. This is a company sponsored device, I can't change some settings, one of them is the "USB debugging" and as such I can't run Gsam or Systempanel2 at their fullest capabilities. I can't root the device either.

    I will keep an eye at this conversation to see if someone will be able to com up with the solution, then maybe I will be able to apply it to LG as well.

    Well maybe that's a good thing, because I assume someone at the company is responsible for them.

    Perhaps you should turn to them with the problem?

    But from your screenshots it seems Android System is only consuming 5%? If so, it's not the same problem.

    Regardless, complain to the company about it not working properly...

    Try clearing the system cache.

    However since this is caused by an update, you may have to do a factory reset if a cache clearing doesn't help.

    I have done factory reset twice already and installed only the very basic apps and disabled all apps that are not relevant. This is so frustrating, this phone's battery lasted the whole day, with heavy use, and still had 40%+ battery left at the end of the day. Now it's burning ~7%/hour sitting idle at my desk.

    I also tried cleaning the cache, as instructed by LG support. No help as expected, since I had already done a factory default reset.

    Really sorry for the dumb question, but how we can take this to Google in a way they will get back with an answer? Shouldn't they tell why Android started burning battery like crazy out of the blue? It seems this is not related to the device as my device is not the same for this thread and yet is presenting the same issue.

    This screenshot was taken about 1 hour after I unplugged it. After few hours it gets to 40%+.

    Even if I complain and they give me a new phone, if the problem is with the OS, it will show up again, I suspect.

    Honestly it would be better to ask LG users because LG's Android is different from Samsung's Android. They add different things which may cause your problems. On Samsungs the problem seems to be tied to Android System, whereas your problems come from somewhere else. So it would seem that it's not an Android problem but an LG problem. Without experience or access with a Nougat LG device, there's no way for most Samsung members to try and look at your case. Especially with the restriction where we can't properly see battery stats.

    Google can't answer your question because as I said, LG modiefies Android to an extent that it's not entirely what Google produced.

    Well, surprisingly this morning my phone decided to go back to what it was before (at least so far, hopefully I'm not speaking too soon). With almost 2 hours of very light use, about 20 minutes with screen on, checked and replied few emails and few whatsapp messages, see how battery is holding on. I did NOT change anything, I only installed Systempanel2 to try to understand better what was killing the battery, yesterday the phone was still very hungry, so it cannot be that the Systempanel2 helped in anyway.

    Fingers crossed it will stat this way. Usually by now, almost 2 hours after I unplugged it from the charger, at least 10% would have gone for sure.

    The first thing happened after i updated my phone to nougat was high Android System Usage...and i ended up using package disabler..disabled all at&t bloatware. Also try to disable all Gear VR background. Still my phone doesnt have the best battery life but atleast android system is now more stable.

    My phone came originally with nougat. It worked great for few weeks, then for about one week it started training the battery like crazy, then out of the blue decided to go back to "normal". It has been working normally again for about a week, so I assume this will be my last post, I hope you guys can find a solution for the S7 and others as well. See below a recent screenshot. This is with light use. With heavy use I get to the end of the day with 40%+ left. I'm happy again with how the battery is holding on the whole day (or more).

    Can I assume that safe mode does not include networking? Since it's the wifi that eats the most battery, then how can safe mode prove anything?

    Try wiping cache partition. Turn off the phone then simultaneously press on the volume UP button, the POWER button, and the HOME button until you are directed to the boot screen. Then using your volume down button select the "wipe cache partition" and press the power button. Then use the volume down button to select yes and power button to enter. Then press power button again and that should restart your phone. I do this after every update and fixes whatever battery drainage occurs after update
    Looks promising, thank you. I just wiped it out and it already seems that cpu works less.
