    whats your screen brightness set at?
    Agreed. Panel App is a battery pig. Don't blame the phone when you install obvious pig apps like that.

    Everyone, when posting screenshots of your battery stats, please include your "screen on" time. You can get this by taping the "Screen" entry in the battery stats. Screen on time will indicate how long were you actually using your phone. Battery stats are pretty useless without this info. FYI, on the Galaxy Nexus typical screen-on time is 2.5 - 4 hours.

    You should really calibrate the battery. I get 5-8 yes heavy use on my normal batteries since calibration. Use the battery until its completely dead. And I mean after it dies take it out and input it and turn the phone back on. Do this until the phone won't even boot up because the battery is so dead. After you have it deal leave the phone OFF and charge it for 6 yes (at least but no more than 8) and your battery will work fine. Trust me, its a little time consuming but the noticeability is immediate.

    Hi Everyone,

    I'm new here but I have a similar problem that needs to be dealt with. After the recent Jelly bean update about a week or two ago my battery life has gone down the drain and the worst part is I'm not even using it. I feel it heating up in my pocket and find out that Android OS, Phone Idle, and Cell Standby are taking up all my battery. The worst part is that after charging it to 100% before I sleep, I wake up to it being completely dead and turned off.

    I don't even know how that makes sense but any tips would be greatly appreciated!

    Don't do this. This advice has been debunked on multiple occasions.

    Drained till power down. Then charged completely with phone off. Best battery life ever. Actually lasted longer than the stock battery for once.

    Any update on this? After three days on JB my battery drains faster on standby.

    Be sure to turn off NFC, and kill Google Wallet, and that seems to help.

    I also found changing my background to something darker helped kick battery life up quite a bit. I've read that white and brighter colors suck more battery than darker colors.

    I'll admit I don't have anything to compare it to from pre vs post jellybean, as I updated as soon as I got the phone a few weeks ago, but with some tweaking and the extended battery (2150 vs 1850, so not a huge difference) I've generally gotten good battery life out of it when I wasn't doing something stupid power wise (4G and GPS with screen on for a long time)

    Thanks for the reply Bront. I was trying to push it for one day charge but it didn't. Had to charge it two hrs before it reaches the 24 hr mark.

    I had to go back to something that manages my connection because at work my cell reception is bad and the battery would go really quick. Before I used Juice Defender (the free version) but now I'm using Green Power Premium. There is a free version and it gets updates pretty regularly, might be worth a try for you. Once setup it runs completely in the background, you can leave notifications on or off and it has a lot of options.

    Of course on screen time is still the same a before, but at least my phone doesn't lose battery life nearly as much as before when it just sits.

    FYI, if you've got 4G in your area, experiment with 4G signal vs 3G. I've found a few areas where I get better 4G signal than 3G signal.

    I turned the phone from CDMA/LTE TO JUST CDMA. The radios are always searching for LTE towers.

    Personally I've noticed no real difference. As LTE is starting to come to Southern California I just turned it on to help with sensorly scans.

    As I mentioned above though I'm using a application called Green Power to help manage the battery and connections.

    I started having this problem on my phone two days ago. I've been running 4.1.2 since it was rolled out OTA (probably more than a month).
    Batter life has been pretty good (usually lasts 14 hours with everything turned on), until two days ago when it suddenly became so bad that the phone will die in 5 or 6 hours just sitting in my pocket.
    The phone also displays "Not Charging" when I plug it in, and stays at the same level of battery no matter how long I keep it plugged. After several attempts and trying to clean the usb port, it finally started charging until 99% when it showed "not charging" again.

    I tried uninstalling the one app (game) I installed two days ago, but didn't change. I've had some applications updated recently (Google Voice, Google+), I haven't tried uninstalling them yet.
    This is making me so frustrated, especially the "not charging" thing. I read in several places that the GN has this issue sometimes and it wouldn't charge unless it's turned off. Mine never showed this behavior before. I don't know what happened!

    Turn off Wifi when you aren't actively using it. That will help a lot.

    Thank you for the reply! I thought HSPA+ consumed more energy. Actually, my droid incredible lasted 2 days on one charge when I turned on wifi all the time, vs 1 day with 3G on verizon. I guess if I'm always near a wifi hotspot that's not a big issue?
    But that's another topic...

    It seems to me that the reason is the battery itself.. I tried completely draining it and then fully charging it while the device is off (took a good 7 hours), and for now it seems to be back to normal. I can't tell for sure yet because I uninstalled G+ updates and GVoice in the process. I'll know after I re-install them.

    By the way, I just noticed that this thread is for Sprint GN, while I have the GSM version.. I didn't notice this before because the problem described matched exactly what I'm having.. I hope that's not a big issue

    As you can see on your screenshot the phone is AWAKE althought the SCREEN is OFF. That means that something keeps the phone awake and consume a lot of battery. I have the same problem too. I can not find a solution

    I think the battery life is better on 4.2.1 and turning wifi off when your not in wifi range will help your battery as well
