Ever since upgrading my iPhone 6 Plus to iOS 8.1, my battery has been draining like crazy and my phone is running hot to the touch, even when I am hardly using it for a significant period of time. As I found out by doing a Google search today, this is not an uncommon issue. http://osxdaily.com/2014/10/21/battery-life-ios-8-1/ I bought the 6 Plus because of the huge battery and was THRILLED with how it had been working up until a couple days ago. I was coming home from work with like 70% battery left, which was just incredible. Now, I've been home all day and barely used my phone and I'm sitting at 60%. This is NOT good.
