Since updating to Beta 5 on my iPhone 5s, I'm losing about 10% battery per hour with the phone in sleep mode and no incoming calls or messages or notifications whatsoever, and with reduce motion on, brightness well below 50%, background app refresh completely off, push email off, and anything else I can think of that would drain the battery. With the phone in complete airplane mode, without even so much as lighting the phone up once, I lose 4% battery life every 30 minutes. Normally I can go a good couple hours in airplane mode and lose maybe 1%. When playing music via bluetooth to a wireless speaker with the rest of my phone in airplane mode (everything but bluetooth), I lose 30% battery per hour. I've never seen such drastic battery drain on my iPhone, a user of every model since the 3G. Previously in iOS 7 versions and iOS 8 Beta 4, I would lose maybe 1-2% per hour even with an occasional notification or incoming message and with all previously mentioned functions off, and maybe 3% per hour when listening to music via bluetooth with the rest of the phone in airplane mode. Anyone have any ideas on how to correct this, or is it now just about waiting for the next beta for 2 weeks?
