Support Random reboots, then significant battery drop (within seconds)

http://androidforums.com – In the past two months or so (I've had the phone for seven) the phone just randomly turns off (maybe 1-2 times per week) and when i reboot it, the battery has dropped sharply (from anywhere between 10 and 70%) within the space of minutes being off. It's legitimate battery loss as well - It takes the same time to recharge the battery back to where it was. Other than when that happens the battery performs well and I get quite good battery life. This happened before and after I got ICS so that can be ruled out, and otherwise I think it makes more sense for the problem to be hardware related. U (General)
