I have serious batter drain going on. In about 4 1/2 hours it went from full to 22%. HELP! I never got the OTA for ICS so I am still on GB. I'll attach some screen shots that might help those smarter then me figure it out.
I actually added that to find out what was draining my battery as it has been happening for a while. I hadn't used my phone for anything as I was asleep for most of that time.
