Searched for a couple days and found a lot of threads with no solution. I have both a standard and extended battery in my year old TB. Standard is original battery and the extended is 10 months old. So battery age is number one concern to me but the phone does the same thing either battery. Running Liquid 3.1, 3.2 to a shit twice on me. Tried to calibrate the battery (extended) by running it dead and charging off and wiping stats for 2 days now, only getting to 91 percent. I think the standard bettery is dust, it died in less than 3 hours downloading angry birds space on 3g and playing it a little. So throw a battery at it then? Thinking this one seidioonline.com 70 bucks is a lot to throw at it though if its another issue.
