I'm finding that since i updated my (development) iPad Air 2 from 8.3 to iOS 9 Beta 1, its battery is draining like crazy. I unplugged with 100% charge last night, this morning it's alreadty dead again. It also constantly is really warm. Instruments shows "blackboardd" running at 20% CPU, the full time, and MobileMail running fairly high too.
Mind you, this is not an "ooh, i upgraded my only production-use device to a beta and now i'm complaining it's not perfect" complaint, so hold back the usual snarky remarks about this. My concern is not only that this iPad is now unusable as a testing/development device, but that i'm actually worried about leaving it running like this at all, for what it might do to the CPU and the battery, long term. The only choice i'm seeing right now is powering it down completely and put it in a drawer until Beta 2 😟.
