Change in 3GS battery life
The battery used to be awesome- I'd unplug it after a night of charging at 6:30am and by 6:30pm the battery would be down to 50%-60% depending on the calls I made. I usually spend 10-15min surfing the web, then 40min browsing the NYT articles/reading books on stanza/kindle, text a bit, make one or two short phone calls. I haven't made any changes to the brightness or fetch or other settings.
My usage hasn't changed- but now the battery dies before 12hrs. It seems like it drains faster and charges far faster. And today when the battery said 20%, it jumped to 53% briefly. Any ideas as to what happened?
The only two new things I can think of are
1) I installed Kindle recently, maybe this is draining the battery?
2) I would only recharge when it would get down to < 10%. Recently I charged it when it was only at 40% a few times because I was going out later that night.
