    My battery only seems to last 7 hours. Brand new Galaxy Note II on AT&T.

    Was there a kind of error with the last multi window update? If so, how can I fix it?

    I browsed the net a little, played a game for a bit. A few texts. Hardly anything unusual.

    Hi

    Thats not so good. I get about 17hrs 100-15% with quite heavy use, but I use Juice Defender to manage the power use. I don't let it get down to 7% as I have heard its not good for the battery.

    How many radios do you have on
    wifi (clearly) but what about bluetooth, data, NFC, GPS ? These all draw power. Try turning on Power Saving in settings. The motion settings enable the motion sensors so this may also be contributing to power drain if enabled. If you have everything turned on that may explain it, but if not I think you may have a faulty battery. Could you swap batteries with someone for a day to test it?

    Thanks! Whats NFC and how can I turn it off? How about how to turn off all the motion controls? I'm trying power saving mode now. Can't swap a battery with anyone.

    NFC is Near Field Communication and in settings under the more settings it has a toggle for NFC and S Beam you can make sure they off. Motion is also in settings and has a toggle as well,

    hope this helps

    cheers!

    It doesn't look too bad to me. The phone was not idle during the 7 hours. It looks like you have the screen on for at least 5 or 6 hours and using the phone. If you have it set on very bright, it will drain the battery in about 6 to 8 hours even with nothing else running.

    Did you power off the phone after your battery was fully charged and the time you took the screen shot?

    That doesn't seem right to me. On my stock battery with 7-8 hours of screen time I usually get 15-18 hours.

    :/ Had power save mode on.... auto brightness on... gps off for quite a while, multi window off for a while, used it lightly here and there throughout the day...
    I got like 5 hours more. But no where near the rest of you.

    Hi again

    Is better but not great. Have you increased the sync intervals for Facebook and email. If set to 5 mins it is a big battery drain. I really suggest you install Juice Defender and work slowly through the advanced settings to set up the phone as you want it. It's quite a sophisticated program (turn off the phones built in power saver in settings as it may conflict)
    I heard that the max brightness in 4.1.2 is 200% brighter than in 4.1.1 (lucidmike78 youtube video) and this may explain any change after your upgrade as the screen the largest battery user.

    Click "Screen" and check your screen on time. Looks like you have about 5 to 6 hours of screen on time. That sounds about right. If you set your screen to about 30%, you would get about 8 hours of screen on time. Anything higher will lower that.

    You could do a battery recalibration and see if that helps as well. Charge to 100% then let battery drain completely or until phone shuts off. Then charge back to 100% do not interrupt the charge.




    Although this is the best way to conserve battery and extend the battery, what's the point of a smart phone then? :p

    Isn't it bad to let these batteries drain that low? I heard don't let it get below 20%.

    I agree with the other poster, click on "screen"-if you're getting 5-7 hours of screen time, no one's going to get much more.

    I found that if you have data and sync on if there's no signal (e.g. no 3g or 4g signal showing) it consumes more battery. If I have to stay in a place where there's no signal and I'm staying there for a long time, I would turn data and sync off.

    Download better battery stats pro. And you can see what clockrate your cpu is at, and also if your phone ever enters deep sleep mode or not. Also then it will show you if you have a strong signal or not.

    Yes I throw mines in Airplane Mode

    The problem with Airplane mode is you also don't get incoming calls and text messages. If you only turn off data and sync, you can still get incoming calls and messages.
