I've lost 20% in about 20 minutes which is pretty fast battery drain for me. Also, phone calls aren't working for me. Phone picks up but I can't hear the person on the other end and they can't hear me.
Gonna do a fresh install and try again.
Also make sure you have the right version for your baseband.
New Baseband = March 11 2012
Old Baseband = July 20122
