Hi,
I have a strange issue with my battery. I've attached a graph

2 am - went to sleep leaving pianobar on and the phone not plugged in
4 am - phone runs out of batteries
4am - 8:30 am - phone battery increases in charge by 50% in the span of 4 hours
8:15 - I wake up and try to turn on the phone and it has no power so it is not able to turn on.
8:30 - I plug the phone in, try to turn the phone on a few times, and it works after the 4th or 5th try
9:40 - after being plugged in for an hour the phone is almost fully charged

Unless I'm reading wrong, how is the phone charging in the middle of the night when its not plugged in?

Also, as of this morning my charging LED no longer turns on. It worked fine yesterday and the only difference is that last night I updated to the newest FCamera.

Thanks in advance for your help.
