    Default Massive Battery Drain on Samsung Galaxy S2 with JellyBean GB27

    I'm searching for anyone who recently installed JellyBean on their Samsung GalaxyS2 4G Epic. Just did the update today because we were having really bad battery performance with the phone with IceCream installed. Went to the Sprint store and they said the battery is fine (and of course had no other recommendations other than buy a new phone). But they did say that the JellyBean update would definitely help. So we did that.

    Have a Model SPH-D710 and are now on Version GB27 (4.1.2). Today the battery was drained in less than four hours. Even with Power Saving on, the Screen is averaging about 50% of the battery with the Android OS in second place taking up 11%.

    If anyone out there has had similar issues and has recommendations on how to best solve for it, I would appreciate any advice you have. Thanks.

    Sometimes when new updates are installed on your device especially huge updates like upgrading OS versions will sometimes have some quirks. Your best bet is to do a couple of power drains. Meaning let the phone perform as expected and let it die. Then charge it completely while it is dead. The next time you use the phone you should see some improvements. Last ditch effort would be to get an OEM battery or re installing the update once again.

    I've had Sprint store give me brand new free batteries for my SG2. They should have offered you a brand new battery. Yup, after a major update sometimes the phone takes a few power down cycles to happen then battery life is better. Also if your wallpaper is colorful it could take up power resources and if you have apps running in the background. I read somewhere using a wallpaper with not many colors helps battery life. Thus using a wallpaper with black color in it helps. I have tested using a wallpaper that is colorful and my battery tended to drain a lot faster compared to using a wallpaper with black/darker colors. That's just my own conclusion!

    Also, if you're in an area that does not have WiMAX you might want to try turning off the Sprint Connections Optimizer. I found it was a huge drain on my battery.

    To turn it off, go to settings, select More Settings, Mobile Networks, Connections Optimizer, uncheck the box.

    Along with the massive battery drain, I find my phone giving me very poor signals most of the time now. Not sure if this is a known issue in the Philadelphia area or as a whole.

    Hello,

    The main cause of battery drain in Jelly bean is the new 'Google Now'.
    Turn it off.You will find a on/off slider in settings.
    Also,enable all the four options under 'Power Saving' before enabling it.
    Thirdly,install the app 'PowerMax' from Play Store and activate it.Its darned good in saving battery consumption.
    I have a Galaxy Note which started having massive consumption of battery (draining in under 5 hours) since I updated to Jellybean.
    After the above steps,its back to 8-8.5 hours -what I used to get on ICS.
    Hope this helps.

    you have to go in to Google, then the settings there is where you can turn it off.

    I kept having Sprint ID cannot connect, but yet it cannot be uninstalled (another issue). Calling Sprint I was told to do the above. First I had to "allow" before I could get the the check mark to uncheck. Next every time I reboot (turn off and turn back on) the phone the check mark will reappear, so I have to go back and allow then uncheck. What a pain. It hasn't helped all the much with the battery drain, but at least it stops the Sprint ID from searching.

    I'm having the same problem with battery drain on display. ~60% of the battery drain is from the display and it discharges relatively quickly. ~20mins of usage knocks my battery from 100% to 60%. Anyone know why or have a solution?

    Sprint Connections Optimizer is off, Google Now is disabled and I've done a factory reset. Light use of the phone (57 minutes of display use) and the battery is down to 24%.

    How old is your battery? Do some searches on these threads you'll find the answer. I don't use facebook on my phone any more. After my reset I've installed very few apps, not even FB and I'm getting avg 12 hrs, sometimes less with heavier use. But if I leave it alone It'll only lose a few %'s after a few hours. But after a year I got a new battery too.

    I have a fairly new battery & seeing much faster battery drain than when on ICS. Screen always shows huge drain, but standby lasts a long time. In fact, when I'm using mine while plugged in, the phone actually DROPS in power instead of charging. Never used to do that before on ICS.

    I had the same issue and resolved by resetting device along with formatting inbuilt device memory and attached SD card. formatting a device will clear old junks. Please take backup of your important stuffs before formatting your device.

    I can confirm that factory reset took care of my issue. Phone doesn't drain as fast & now actually charges while using it.

    Thank!

    I had the same problem, lucky to get 3 hours after the 4.1.2 update. Called Boost, and was told to do the reset option on the phone, of course you will loose all info on the phone, so back up with google and it will be beter after, but now the phone locks up at idle sometimes, and I never know when until I go to use it! It turned a great phone into a ZTE warp! I do hope they come up with a patch fix! I even asked if there was a way to go back to ICS, but no there isnt. The other problem I have is screencap is no longer working... I loved that option.

    I was just browsing the web on my phone. Battery was at like 41%. Then phone lost signal and straight up died on me. Tried to turn it back on, but battery was at 0%. Got into work and plugged it in and turned it on. Battery was at 51%.

    Third time my battery has done something weird like this.

    Absolutely same problem. Vodafone sent me a new phone with their install of JellyBean, which had the same problem. Major drain in idle (but at least it didn't get hot!) They have now given me an older IceCreamSandwich version with updates turned off.
    Wow I'm please to have a rest for battling with Kies (which must be the worst corporate commercial software ever written) and reinstalling apps. Maybe a Sony Xperia next time.

    Yup, Factory Reset fixed my problem too. I was primarily having a reset issue, but I was also seeing horrible battery drain and my phone was warm all the time. Turning off Google Now and using power saving had absolutely no effect. I backed up my apps and data then booted to recovery and reset. It stopped restarting and battery life is the best I've seen over the life of the phone!

    I think I got my phone dialed in pretty well. Did most of the stuff stated above, got rid of some apps too. I don't use the phone for more than calls, texting and emails too. I think the phone does a good job of monitoring itself without the help of apps. I tried juice defender and power max and they seemed to cause more problems than fix. Got rid of Facebook and Photobucket also. Am using widget locker, Tesla unread plugin, circle battery widget, ClockQ, Quickshortcut maker and few others (Pandora etc) and power is just fine. Unplugged the phone at 4pm yesterday, light to medium use til bed, left it unplugged, light to medium use this morning and at 19 hours it was at 42% . I'm digging it.
