First try a cache wipe. If you don't know how to do that search the recent threads for discussion on how to do that. That has worked for some people. I had to do a factory reset to fix my battery.
I had the same issue - Phone Hot, and loosing battery super fast. I did a cache wipe and then did a battery pull. Phone seems to be back to normal-ish battery use. Hopefully that fixes it for you too!
