Is there a way to force it into power reserve, without going below the 20% threshold?
It's in Settings>Battery>Toggle Low Power Mode 'On'
Is there a way to force it into power reserve, without going below the 20% threshold?
Bad, went to sleep with 92% on the 6 and woke up with 44%How's the iPhone 6 and air 2?
I've had horrible battery life as well on my iPhone 6 since iOS 9 beta. It drained around 10-20% per hour even in standby mode.
I tried to debug it using XCode Intruments. I ditn't see anything special, except for a bit high backboardd CPU usage. Cellular data usage seemed to be the cause, as the battery life was great in flight mode.
Today I did a full DFU restore, restored my backup from iTunes and disabled iCloud Backup and iCloud drive. I think it fixed the issue! I've been listening to music for around 1 hour now with everything else enabled and I'm currently at 99%
Many thanks to Atomic Flip. I have noticed that since upgrading to ios 9 public beta that standby is ok but as soon as there is any use the battery drains very quickly. 45 minute tube journey this a.m. dropped by 25%age points whilst listening to the new Music App. Also noticed that iPhone got extremely hot during charging. Have now disabled iCloud Drive and reverted backups to MBP. Currently charging and device is noticeably less hot. Will update if this works but seem eminently logical to me. Is it me or does the phone seem to charge less quickly after this upgrade?
Just had a 15% drop in battery during a 45 min tube journey whilst listening to Music even in airplane mode. Does anyone know if there is any research on the new Musinc App degrading battery life?Yes, the phone now also takes ages to charge...
Right. I recharged the phone to 100% All well. Phone cool (heatwise). Had turned off Apple Music Streaming. Got 45 mins at 100%. Decided to have a look at Music to see if it would drain the battery. Turned on Apple Music Streaming. WIthin 1 min the phone was heating up and lost 3%age points in a matter of a couple of minutes whilst I was playing around with the settings. Note, not listening to any music! Now recharging phone to 100% and the heat has gone. Is this another API issue?Just had a 15% drop in battery during a 45 min tube journey whilst listening to Music even in airplane mode.

I'm convinced most battery issues at this stage are caused by third party apps. When I had Twitter, hangouts, google plus, and iWork apps installed after a clean setup, my battery burned at 1% per minute. Before installing any apps, it was phenomenal.When I under ios 9.0 public beta turn on the flight mode and the battery safe mode, consumes my iPhone 5s still 10% battery capacity per hour. In normal use it consumes up to 30% per hour. The battery drain is very worse since ios 8.3

Yea tried that. Even with iCloud completely disabled the issue remained. I now have iCloud completely enabled this time around (but no third party apps) and battery life is perfectly fine. Not saying it couldn't still be an OS bug, but if the boot fits...Have you looked at disabling everything involving iCloud? That's what seems to be the issue for most people - Since I disabled it in Dev B3 I'm actually getting mildly better battery life than 8.4 on my iPad Air 2. The jury is still out on my 5S.

That's crazy you're seeing such a drain on battery. Yesterday I took a train from the very south end to the very north end of Calgary (which is a 45minute - 1hour ride.) The battery was at 96% when I got on the train and still 96% when I got off the train. Listening to music the whole time, but I never played with the phone at all during that time. Screen off and just music playing through stock Apple EarPods.
