I have occasionally had this trouble with almost all builds I have tried. Not sure what causes it, but all of a sudden, the Bold heats up, and the battery really discharges quickly. Sometimes it will self correct after battery pulls. This last time it would not correct, so I wiped with Crackmem and reinstalled. Seems fine now, but who knows. I actually exchanged my bold a few months ago due to this problem. Just pops up now and then, wish I knew why.
