Battery won't calibrate

I've tried everything but reboots still make my battery jump. Right now it went from 9% to 59% on a random reboot

I don't know what else to do. I've done the battery calibration app. I have no battery stats in system/bin to delete (I believe that was the folder) and I've done battery stats erase in recovery, still doesn't help.

Try using a different battery. If you were using a SBC kernal you might of killed it.

The Wakelock thread

Just thought I'd start a thread for people to post and diagnosis their wakelocks. I have a *backup* wakelock on a completely stock sgs3. Here's a screen shot. Any help? Can't for the life of me figure it out. Android system use is at 20% on the stock battery app.

uncheck the backup box in settings. See if that helps.

I did see one thread that recommended that but there's gotta be a better fix than that right?

Auto update apps turned on? Did you try to update apps with poor data coverage. Looks like something with an app update hung.

Probably a memory leak or wake lock somewhere... just reboot the phone, it be really odd if it ever did it again. Remember this cpu is producing errors left and right, there is an entire section of the phone built entirely for correcting these errors. Sometimes it doesn't work.

For those suffering from poor battery backup with official jb

For those having heavy battery drain after official jb update try the following setting under location services, it works great with just 1-4% battery drain in standby for me in 10-12 hrs:

This would render some of the Google Now services useless, isn't it?

I've used this trick in the past mainly to disable the stock maps app from wakelocks. It works for battery but is annoying if you need some of the other google services on tap.

it works for me. thanks

[HELP] kernel and android system draining too much battery!

I left my phone at 83% before going to sleep. When I woke up, it was only 72%. I can't seem to find the culprit. BBS also shows about 2 hours difference between screen on time and device awake.

Here you can see what my battery drain is like. My screen on time isn't bad but the other is.
