    I came across this thread, been having similar issues with my Note 4 battery life. I'm on AT&T and Android System is always taking 20-30% of the battery on any given charge. Best screen time I got was a little over 3 hours.

    Also, showing that the phone is awake a lot longer than the screen is on. Even when the screen IS on, I can watch the battery percentage easily drop 1% every minute or two.

    I even tried a factory reset, and just added my Google account to the phone - turned off Wi-Fi scanning, location services reporting, bluetooth, and GPS, same issues.

    I'm on US Cellular, running stock TW and having no issues whatsoever with battery life. I'm actually quite impressed with how long the battery lasts on this, compared to my S4 and S2.

    Just got my AT&T Note 4 yesterday and today my battery is not so good. 2 1/2 hours of on screen time and I'm under 50% remaining.

    I charged it full last night and am going to drain it today until it's dead then fully recharge.

    I'm not concerned at the moment and will see if it improves over the next week or so.

    My Note 4 has the same battery drain issue. I went from 100% to 80% in one hour during which I was doing facebook and web browsing and 10 minutes of music using my headphones.
    I'm going to return it while I still can.

    I may have found the cause on my drain.

    I had one email account setup with Exchange but since changing it to imap the drain is much less..

    If you have an exchange email account, check that maybe. I am almost out of juice and will do a full recharge then report back..

    That's not necessarily an unusual drain of battery with a new phone. Especially if you're still in the process of getting the phone set up. I drained a good deal of batter from my phone the first day trying to get everything set up. It has been excellent in the days since.

    Thanks for the feedback . I got the phone for two days only . I was charging it only through USB connection to my laptop . I need that becuase I'm tethering . When I get home today I'll charge through AC outlet using adapter supplied . I hope that will resolve the issue.

    Im currently on my best battery charge yet. I charged the phone after school before heading off to a Halloween party, used it sparingly there for obvious reason, then used GPS and bluetooth and pandora to get me home about an hour and thirty minute drive getting home around 4 am. Once home I was to exhausted to think about the phone and just fell asleep without charging it and decided when I woke up to just act normal and see how far I can go on this battery and so far im at 23 hours on 35% battery remaining. I had the foresight to turn power saving mode on the phone before falling asleep, and I kept it on all day (the stock setup with that, no grayscale or anything). WOW. Couldn't ask for anything better.

    Hi everyone.
    I use galaxy note 4 exynos version and I think I also have a battery issue. I have ny screen brightness auto +5 and check the screen shot...screen consumes 50 % of battery life? Is it ok? I switched from note 2 and looks like the battery life is definitly worse than in note 2... im from Poland thats why screen shot is in polish but i think you know what i meant

    This is purely anecdotal but I have amazing battery life after coming from Note 3 post-KitKat. I think I may have said it earlier in this thread...then Monday my daughter asked me to play Words with Friends since she is away at school and we can't play Scrabble anymore. Immediately I saw it drop ...like maybe 10 points in an hour. Then I saw a bunch of Google results on 'words with friends battery hog'. So those of you with facebook games platform and things like that may want to check. It would account for why some see problems and some don't.

    One solution I saw was to "Restrict Background Data" on a per app basis in settings. I didn't save the link. Just look in data usage and battery usage. If you see something using even more than Screen in battery usage it is a problem. And I guess restricting data usage on this app makes it stop doing what drains the battery. It was something about the game constantly checking for the next move as opposed to the move just being sent. EDIT...Adding that it doesn't use much actual data...

    I'm having issues myself, or at least I think it is from what I've heard about this phone. Granted it's light years better than my iphone 5, I still get unusual off screen drain time.

    I'll lose around 15-20% during sleep. I also noticed today, I got in work at 9, and had meetings up until about 1. Very light use obviously during this time...but I'm currently typing this at 59%.

    I looked at my meter and words with friends is using 37%...I probably have to many notifications on somewhere...I'll still get through a full work day. But my screen off time almost seems equal to my on time.

    I did just notice I keep getting the location symbol at top, even after I dismiss it. It's set to high accuracy, and it seems like it's constantly searching. I'm going to lower that and report back.

    Words with Friends is huge...Even though I restricted background data and it is better it is still the highest battery usage item. Other than that my battery life is great. I saw out there that it is constantly asking the network"did the other player play?did the other player play? again and again instead of having a way to just wait for it. Like when people talk about the phone radio searching for a signal. Uninstall for a day or so and see what happens...

    Really ...so what's the fix for this? Does turning all game notifications off help? I don't want to Uninstall it, but I always don't want to continue eating my battery alive.

    I do notice since I typed that, and lowering my location search from very accurate to the middle setting, that it seems like it's doing better already. I'm now at 48%, and my usage has been much heavier from 59% to 47% than from 100 to 60.

    Someone has to help me with this, google OS/kernel are eating up 65% of my battery, while sitting on my desk. It's down to 40% and I'm not even using it. I've literally turned off every fancy setting on this phone, and it's still terrible. I deleted every active widget except weather and the stupid s-health, to no avail. Others seem like the main drain is their screens, but I'm not even using mine (screen used 18% of battery) It's literally gotten so bad I carry my old iPhone in my pocket to actually do things I want to do so I don't completely kill my battery. I bought this phone explicitly for the battery life, so I literally couldn't be any more disappointed

    I saw someone say that exchange was needlessly syncing in the background all day, so I completely deleted exchange accounts and no change. Saw another user indicate renaming the "my documents" or "mobile documents" folder fixed his issue. Did the same, nothing.

    I'm at my wits end here, I'm literally about to take this piece of junk back. I've been trying for two weeks to remedy this problem and it's only getting worse. Seems like other ATT users have the same problem, is it related to the carrier?

    I had that wrong, the stats are much worse. android system used 48%, android os used 19% (67% combined), and my screen accounts for just 6%. Something has to be seriously wrong, anybody able to help?

    Get GSAM app. It'll help you find what's doing that. You don't necessarily need to turn off everything. You need to find the one or two that are eating up all the power. There are lots of reasons but often it's one app doing something like constantly trying to update a document that doesn't need it or keeping the phone awake or cranking for a signal when it shouldn't etc. The fix seems always to be easy once you find it. Finding it is the hard part.
