A typical charge on my iPhone 6 on Public Beta 3 (DP 5) is 8-9 hours usage with over a day standby.
Whaat, let's see a SS of that. Battery life is quite a bit better for me on B5 vs 8.4.
This is exactly how my iPhone 6 has been even since iOS 8.0 and all the way up through everything else. PB 1 and 2 were quite bad and PB 3 has been similar to iOS 8. I still miss 8.2, I consistently got 8.5 hours or more from that version. Got 10 hours for the first time ever back then. Then 8.3 came along and I couldn't get any more than 6.5 hours, still can't.From the battery screenshots everyone is posting, it looks to be 4-6 hours of usage with the past couple of betas.
