    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 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.

    I'm having similar issues. found this thread when i still had some hope for my phone, but even this thread does not get any results. I would be more than glad to know of any method which works and I was wondering if this problem would be fixed by a software update and if yes then when is the same going to arrive.

    I've had battery usage problem on my Galaxy6 for months which started the day I upgraded to nougat. Highest usage is Device idle followed by Android System. I do nothing with the phone. The factory reset didn't help, nor cache wipes. Safe mode and MAX power saving mode turn off all the extra apps, and that does not help. I used package disabler and disabled lots of stuff and that doesn't help. I completely discharged and recharged the battery. I've "reset" the battery (procedure described on another thread in this forum). Same result: about 3 times the battery use compared to MM, no matter whether I use the phone or not (if I use it, it burns about 2-3 times the power for the same tasks).

    I also went to the Sprint store to ask to go back to MM. They couldn't or wouldn't, but they did reflash nougat for me which was nice. But it didn't help. In short, nothing helps, there's no solution. But I might try a different launcher (mentioned above). Just noticed "developer mode" was on, although none of the developer mode features were on. So I just turned that off. Turning off developer didn't seem to help. Also my launcher is touchwiz which must be Samsung, so I left it alone.

    Thought I would add to this, got my HTC 10 from Verizon on 7/1 and later that day got the update for nougat. After that the Android os was using upwards of 40% of the battery, Android system using 28%. The phone was constantly awake and would drain overnight on airplane mode. Did 2 factory resets, cleaned cache partition, ran in safe mode, and disabled literally every app and service. Something deep in the software is keeping the phone awake and killing the battery. Was told to go to the corporate store where they had laptops and could downgrade me back to 6, yet when I got there they looked at me like I had 2 heads. Ended up exchanging the phone and am holding off the 7 update until I know this isn't going to happen. If you are dealing with this problem and your phone is not rooted there is no hope for you until an update is released to fix this.

    While I'm an HTC fanboy I have to say I'm not experiencing this issue. Reading thru the comments I will say that HTC doesn't seem to play nice with 3rd party launchers. Perhaps they've improved this since it was a gift topic in the forums but they probably are still going Sense is a big hit with its users. Anyway the big hitters on battery are always going to be UI, OS, and screen on, usually followed by apps. If you find your device isn't sleeping or consuming large amounts of battery with the screen off there's something keeping it going which is likely an app and just because something wasn't an issue prior to an update doesn't mean that it will continue to play nice afterwards. While we have mostly gotten away from factory resets in the past after big updates it is sometimes still required or recommended when these small issues pop up. I personally prefer it because the update tries to make changes while the system is operating and depending on what is installed and/or ruining this isn't always successful. The FR afterwards installs the image in whole and while the system is clean and free of background noise, if you will. IMO it's the best way to update, minus the lost bits that is. Plus it has the added benefit of freshly installed apps, which don't always like change either. Some might feet away with a cache wipe but FR and being stock has seemed to work well for me.

    Actually no - all a FR does is delete any changes you've made to the phone. It doesn't reinstall the image. (If it did, you'd need a new image [which is a few GB] every time you got an update.) It doesn't reinstall anything at all.

    (If the update requires a FR to clean up what;s left from the old version, blame the manufacturer or Google - one of them forgot to delete the leftover garbage.)

    But if you run Wakelock detector with non-rooted phone (or just run Wakelock Detector if your phone is rooted), you might be able to see what's waking the phone up most - and that's what's using the most battery. (Any update to the OS is going to use a lot of battery for the first few days, rearranging things and downloading things it needs, but if it doesn't stop after a week, see what's waking the phone up. Not by the order in which they appear, but in the number of wakelocks.)

    The reason Android OS uses so much is that a lot of things that used to be done in separate files were moved into Android OS, so one file update updates a lot of functions. It also runs a lot of functions. But that's normal Android now.

    So its normal android for a device to drain 50-70% overnight on a nightstand in safe mode or airplane mode? What is it "running" at that point consuming that much battery while never turning the screen on?

    I second the reply talking about wakelock detector. Gsam is another well respected battery monitor that can give better more precise information about what is keeping the phone awake. The default one on android settings is not really that much helpful.

    You can get wakelock information If you're on a rooted phone very easily and you can still get wake lock information with an unrooted phone is just that it needs computer and some following of instructions. If you're posting on this thread b then I would assume you should be able to follow those instructions. Just install gsam and full instructions are there in the setup or in the settings menu.

    Can someone explain how GSam shows what is keeping the phone awake? My Galaxy s6 is not rooted. The held awake screen almost never shows "deep sleep" (1% at most). The doze time light to deep ratio is about 5:1 The app usage screen shows just "combined app usage", and it varies widely whether I use the phone or not, but generally it is 40 to 90%. The rest is generally screen or "held awake".

    The sad fact of the matter is...Android phones are not the 'Perfect' phone as advertised. Running all features -Location, Auto Sync, Backup & Reset, Bluetooth, Fitness Sync, ect), and all installed apps with their background processes going at all times, plus the phones' radio will kill your battery while idling (Screen Off).

    My experience to better battery life has been one of compromise. Disabling apps I will never use, disabling Auto Sync, (I do it manually), disabling location (Until I use GPS), vibration, body sensors, Automatic updates from Playstore (I do it manually), Automatic Android updates (You can check periodically), disable Wi-Fi when outside (It is scanning while you are walking around, a battery drainer), Disabling Facebook app (A known battery hog), I use my browser. There is so much more...

    Have you tried using the Greenify app? It hibernates most apps while your phone is in 'Doze' mode.

    Have you tried checking permissions in your individual apps and turning some off?

    Before disabling an app, clear it's data first.

    It is not 'Normal' for Android to lose 50-70% overnight (6-8 hour period). Possibly a rouge app(s).

    What is 'Running' while your screen is off? ...Routine maintenance, apps polling for messaging, there are analytics (I call it spying) performed for advertising (Through separate apps & Google itself), app usage, crash reports (Even if your phone doesn't crash) how, and when you use your device, what apps you have installed, there are update scans for individual apps through google Play Services, which then all gets sent to Google servers from your device. Android OS must process these actions, which may account for high 'Android OS' 'Google Play Services', or 'Google Services' use in Battery History. Of course, these actions chip away at your battery while you sleep. Certain OS level processes still occur in Safe or Airplane Mode (Though Lessened)

    I am simplifying, but I hope you get the picture.

    My HTC 10 is rooted and heavily optimized, so I experience 0.3% per hour battery idle drain in an 8 hour span (While I'm sleeping). Root is not for everyone, but one can lessen the drain effects slightly through compromise while not being rooted.

    Preferably, if you could take screenshots of your GSAM report, and post it, we could probably narrow things down. I use Better Battery stats as it provides a visual display, and an option to generate a log. I also use Wakelock Detector. I am rooted, but there are still avenues you can pursue.

    I would suggest letting your device idle (Don't touch phone for 6 hours), generate the GSAM screenshots, and post them.

    My Better Battery Stats 'Summary' shows battery drain during 'Doze', the next shot shows items with significant 'Wakeups' while the screen is off 'Alarms', and the Battery usage history in a 6 h 58 m period.
