I've had a noticeable drop in battery life after upgrading to iOS 8.1 on my iPhone 6 Plus. Anyone else have similar behavior? I have the exact same setup on both installs and I'm getting 1-1.5 hours less on 8.1. Note - Yes, I know that Music is higher on the iOS 8.0 screenshot. It's probably because I was using Bluetooth Airplay that day, as opposed to headphones on the iOS 8.1 screenshot. You can see that my usage patterns are very similar.
