Odd, this just started when I was up in MI past few days and coming back. Now when I'm on a call the battery drains pretty fast. Like I just had my phone unplugged at 100%, gf called, chatted for about 5 minutes and it already dropped to 93%. No idea what's causing this? edit - she just called back and it went from 93% to 89% in less than 2 min of talking????????
