    Default Re: 4.2 battery life

    I was running paranoid android before so I had to fresh install, I just ran the 4.2 factory image straight on it.

    Everything else works great other than the drain

    I, myself, updated via OTA. It shouldn't matter in my opinion. Maybe we're all just paying too much attention to the battery life, and subconsciously expected to be more life?

    I believe you can manually update, which probably also fresh installing.

    I don't feel battery life has been any better or worse since my 7 updated to 4.2.

    Someone correct me if I'm wrong... I think what's meant by a fresh install of the 4.2 update is if you did a factory reset and install the update before installing any apps?

    I did not do the factory reset before installing 4.2 and I've noticed faster battery drain, bluetooth cutting out, and subtle screen flicker. Although, either the screen flicker isn't so bad anymore or I've gotten used to it...

    Anyway, I'm considering Doing factory reset and trying the update again. But will a factory reset take the OS back to 4.1 (or whatever version it was when I first got it) now that I'm on 4.2?

    Google really needs to start Project Roadrunner for battery, because this life doesn't last.

    So this battery is lasting longer b.c I put it on airplane mode every time i leave the tablet idle for long periods of time. Exchange Services (work email) and ,APS I used for like 30 seconds each and look at their batter consumption! Both were not running in the background either.4.2 battery life-uploadfromtaptalk1353816921326.jpg


    Not saying the 4-3% is that much for long term but I literally had them on for 30 seconds each haha

    Are you all using Live wallpapers? Two nights ago I realized that l switched my wallpaper to one of the new Live wallpapers that came with 4.2. Of course that was shortly after I upgraded to 4.2 and started noticing the poor battery life. I then switched to one of the non-live wallpapers and my battery seems to be lot better and the Google Services isn't so high on my battery stats:

    But Maps is still pretty high on the list and I don't think I even used it!

    No change in battery life for me. Getting at least a full day of use off a full charge.

    If you are having issues, do a factory reset and reinstall apps manually - not from a backup. Battery drain can be caused by app data/cache issues.

    No live wallpaper for me. I tried different battery saving strategies this charge and next time I charge it up I'll try something different ya know. Hopefully something gives.

    I agree that 4.2 has shortened the battery life, but I actually improved it a bit by uninstalling Juice Protector or whatever it's called... Weird.

    It's probably not optimized for 4.2 thus the improvement

    High power consumption by Maps, especially when you're not using, may be due to the Network Location Service. I first encountered the bad behavior on my phone and disabled the service there. Then, did the same on the N7. Made a big difference in battery life. Even though I turned off WiFi location in Settings, I still had to disable the service to get it to stop running whenever it felt like it.

    Maps has been known to accidentally turn on the GPS and leave it on. So, you might check that too.

    I've also noticed that you can disable a different option. If you go to the three dots at the corner---> Location Settings, you can disable automatic location reporting, which happens to be under 'Background Location Reporting'.

    I had the problem with Maps sucking power even when not used before the 4.2 update, but the new culprit appears to be Google Play services as noted here:

    I (and others) have noticed Google Play Services has absolutely eaten into my Nexus 7's battery life post-Android 4.2. Usually, I get a solid 3-5 days of standby time if my Nexus 7 is sitting mostly idle, but after leaving it alone this weekend for under 48 hours, I returned to it at about 8% remaining. Not good. Similar issues have been brought up by Galaxy Nexus owners. In addition to that, exchange accounts are apparently causing massive loss in battery longevity. The exchange issue can be alleviated by removing and re-adding your accounts, according to some of the bug threads.

    The Google Play Services problem, though, doesn't seem to have a solution presently, and reportedly is affecting all Nexuses. I'm also hearing from numerous people that NFC is causing extreme battery drain in some cases across all Nexus devices, a problem I, too, have experienced.


    I don't have NFC on, don't want to turn off location services (and they weren't a problem before), but GSam Battery Monitor reports Google Services with Play a component being THE major power hog. Here's to hoping 4.2.1 squashes these bugs.

    One of the main culprits for me was Google currents. It apparently was making the whole tablet lag. I went into the app and disabled background updating and that seemed to take care of the lag and have me better battery life........I can't take credit for finding it though. I read it in an article...problem android central.

    I just updated to 4.2 a couple of days ago and contrary to others, I have seen same or battery battery life. One thing that is definitely better now is charge time. It was taking me almost five hours to fully charge this device and now it charges in half that time. The only issue with 4.2 so far is Bluetooth connectivity but I hear that it will be fixed with the 4.2.1 update.
