It seems this update has been killing my batter all week. I'm currently downgrading to 6.0.2 For instance, today my phone was fully charged at 11 AM. I didn't use it much all day and it was down to 10 percent at 3. Then charged it up to 70 percent at 3 o'clock. It was dead by 9 after being in my pocket the entire time with no use whatsoever. What's up with that?
