    It shouldn't drain 60% over night if everything is working properly. Go into battery stats and take a look at what is running. Perhaps take a screen shot and post it for use to take a look at.

    I'm guessing the device could be searching for signal or an app is syncing over night causing the device to stay awake and not sleep properly.

    You should turn your phone off and let it charging overnight. I do that and my battery lasts for about 6 hours, and I use my phone constantly.

    You should use it a week and report back. Your battery needs to break in.

    Have you tried The Battery Doctor app? I use it for my Note 2 and its awesome! Look for it on the play store. Link below. You don't have to be rooted.

    I am having the same problem with my Galaxy S3. I bought it back in June and the battery seems to drain incredibly fast whenever the screen is off. I've checked a number of forums and disabled pretty much everything besides Wi-Fi. I mainly use the phone for chatting, internet, and a few language apps. Running Battery Saving Apps hasn't helped. For example, when I have about 90% battery it says that I should have around 16 hours of battery remaining but in practice it's probably a quarter of that time.

    Not really sure what else I can do. I've read elsewhere that this problem is somewhat common and may be related to an update. I'm running JB 4.1.2. My last resort option is to backup and factory reset all the data. Any other advice?

    These days many apps using phone while it is idle. Syncing, Notifications, Updatings etc...
    Eventually, they drain phone battery..

    The good thing is you can now monitor all those behaviors, as all of them use the same feature called "wakelock"

    Check out this guide of how to do it:

    Solved!!!!

    Just hard reset your device and recharge your phone full. Go to settings>account>factory reset. Warning: You will lose all your files in device unless you save them.

    Thanks,

    What??? Factory reset is your solution?

    That makes no sense. First thing I would do is check the WiFi signal. If it is weak, it will drain your battery quite rapidly as the phone is continuously trying to find/connect to it. If that's left on overnight with a weak WiFi connection, you can bet that half of your battery power or more would be consumed.

    In any event, why are people sleeping with their phone on. You should be looking at the automatic power on/off schedule. My phone sleeps at 1am and wakes at 6am. Typically, it's recharging during that time. So it's at 100% when I get up, and by the time I go do bed, it's ready to begin the recharge cycle. I also use the battery save feature, and I also use the No-Frills CPU control app (phone is rooted) to keep CPU running at less than full speed. Plus I use Greenify to hibernate some apps that just stay running in the background even though I'm not using them...that chews up battery power too.

    I would charge my battery overnight to 100%. 4 hours later the battery would be at 10%. This has only happened in the last 2 weeks. My phone would also be red hot after charging After reading other forums I have done the following

    1. Turned off motions and gestures and Air View from the Settings. I didnt really use these anyway
    2. Turned of Use GPS Satellite from the Location in Settings
    3. Clicked Power Saving Mode from the drag down menu
    4. Disabled sync in the Settings - Accounts for all the accounts
    5. Downloaded Battery Booster Lite
    6. Deleted the last 3-4 apps I downloaded - could have been a rogue app
    7. Turned off Wi-Fi when I was not in a Wi-Fi area.
    8. Deleted cleaner apps. Manually deleted cache etc from the Settings-More-Applications Manager

    Nothing worked. I still had the same problems as before up until yesterday. I read on another forum that the sd card drains the battery on the S4. I took out my sd card. Simple as that. It worked. I have taken my phone off charge 3 1/2 hours ago. Battery is at 80%. Would have been down to 30% or less when I had the issues.
