Anybody else experiencing short battery life with IOS 9? My iphone 6 will not last 4 hours without a charger on it. I was getting great battery life with 8.4, it was even charging more than I was using with maps on and driving. IOS 9 will not last 4 hours with maps on and driving, even with the charger plugged in, that was the same with 8.3, not sure what happen but 9.0 went backward on battery life.
iOS 9 battery life
Yes, I'm having problems with the battery life on iPhone 6 too.
With 60% of battery, locked screen, after about six hours (when I was sleeping) the iPhone was shutdown without battery.
Now I already had upgraded my Notes app and I'm afraid to downgrade and stay without my recent notes... I hope that news beta version come hurry.
Perhaps next time search the forum as there are already several posts related to this issue, with numerous people confirming the same..
Easy solution - allwajs kill all app if you don't use them. All of them not updated for iOS9 yet and may eat battery while in background.
iOS 9 battery usage by my measurements is reduced 62%. In addition overall performance is about 30% slower right now. I assume it's the beta build. iOS 8 was that way in the first couple of betas too.
I have tried killing apps, which stopped affecting battery issues in ios 8 beta 4 if the app was properly updated for BGD Refresh, and also just letting them all stay open that I use regularly (there were 30 in the background yesterday). Both ways on iOS 9 b1 didn't change the crazy fast battery drain.
Example: I went to "Jurassic World" on Thursday arriving at 7:15 pm for the 8 pm showtime and unplugged from the car with 88% on my iPhone 6 (Apple Watch at 70%).
At the start of the movie, granted I had checked in on Swarm/FourSquare, looked at local weather, checked my "RunPee" App as to not miss any crutial parts of the film, and checked my "After Credits" App for possible after credit alerts (there aren't any), the iPhone 6 was at 70% (Watch holding at 68%).
Fast forward 124 minutes + ~15 for previews, basically ~2hrs 20min and much to my dismay iPhone 6 at 25%, Watch at 40%. I do remember receiving about 10 news/weather alerts, and about the same in other notifications (phone on Vibrate, and Watch on mute (not DND).
**Speaking about notifications since iOS 9, I receive all notifications to BOTH iPhone and Watch regardless as to which one is the dominant. I didn't realize how intuitive Apple was with never duplicating a Tap here with a Vibrate there, or a Ding/Tap, Vibrate when using both iPhone and Watch all day back and forth. I'm wondering if there is something blocking that pathway. Because prior to iOS 9/Watch OS2, if my phone was active I would NEVER be notified on the Watch, and if the Phone was in standby, only the Watch got all the notifications. It had just worked on Wi-Fi or Bluetooth.
Yep it always happens with the first test releases. I Imagine the primary culprit is that iOS is probably logging everything. That'll kill battery quite effectively.
It seems like the homescreen/lock screen (Springboard) is eating a lot of resources. Just a guess, but it could be the the new Proactive Assistant is not yet optimized. Try always running in low power mode in Settings > Battery. I've had good results with that.
I am seeing this as well. Left my iPhone 6 with 60% over night and in the morning it is down to 17% and I did a complete restore with installing each and every app manually.
I hope a new beta will fix this, but like you guys already stated using some of the new features like Notes makes it hard to go back to iOS 8.
I've seen the same problem, though I've noticed that if I turn off wifi, bluetooth and cellular data the battery drain is almost gone. After turning off all these services my iphone 6 only lost 3% in standby over the course of the night instead of 20-25%.
I'm having problems with the battery life on iPhone 6 Plus too.
you can go to airplane mode when you do not need connectivity. This stops the hight battery drain.
Here part of battery life loss seems to depend on active screen display. Before iIS9, screen display burned battery at some rate we'll call X$ an hour. With 9B1, this seems more like 3X or 4X.
So before a clock display might have burned 25% over the course of a night (7 hours), but now it might be 75%. The new Battery tracking option in settings shows similar loss due to Home Screen display.
to test after my GPS consumes battery because moving drive the car charger can not find a iphone ( Waze )
Following procedure has helped my battery life:
Swipe down to open Notification Center
Today view
Edit
Remove "Traffic Conditions"
Done
Swipe up to close NC
YMMV
Killing apps won't save any battery - in fact unloading them from memory uses power that otherwise wouldn't be as the apps will likely be sleeping and therefore not consuming any power.
