Since i got 2.2 it is taking much longer to CHARGE my battery. Before the update, it seemed to gain about 1% every minute, so about 1.5hrs to go from 15% or so to full. I thought it seemed longer lately, so at about 11:20 i plugged it in with 17%. At 1am, it was at 66%. Usually it would be close to or at 100%. What gives? edit. im using same stock wall charger, and same outlet(s) i used previously.
