Battery charge jumped from 60% to 100%!!!

I had 60% left and put the charger in and it jumped to full charge in an instant.

 

Maybe your battery indicator is acting up. Apple recommends draining the battery once a month to keep the indicator accurate.

 

My battery goes down all the way quite often. I often charge up from dead.

 

Maybe try restarting. Elsewise, hope it's a glitch, because users who've had battery probs sometimes seem to have a hard time shaking them despite firmware upgrades. Apple said iOS 5.0.1 was supposed to fix battery bugs. Then it also said iOS 5.1 was supposed to fix them. But I read that battery bugs can be hard to fix, because there are so many variables in user settings, involving push, location services, etc.

 

5.1 has taken my battery usage from 8-10 hours or heavy use downtown about 2-3 hours. Also,it now take almost 6-8 hours to charge the device. VERY disappointed.

 

I'd try draining the battery and charging to 100 percent again. Would try resetting as well.

 

I wouldn't let it go fully dead. 5% or so is good enough to calibrate the meter. I don't think batteries like being fully dead. Just a thought.

 

IPad shuts itself down before it goes dead.
