iOS 9 Beta battery life

Same here.

Also my iPad Air 2 gets realy hot even if I do simple tasks like Safari webbrowsing or using the facebook app.

Beta 1 - around 3 usally have bad battery life so that is not unexpected. In my experience this year is much worse than I've ever seen. Home screen seems to be the culprit according the usage data so I'm guessing it's spotlight related.

Surprised so many people are needing to downgrade though. If you have installed this you should be a developer and hence spend most of your day next to a computer. Just put your phone in the charger!

With the screen on, in a dock connected to the iMac, the battery is going down, not up. The power drain is greater than the power supplied by the lightning cable.

I've been running the phone in many different modes now, what i could se when I woke up is that there's that spinning icon right beside the operator text in the top whenever I go to the homescreen and it doesn't matter if I'm on mobile data, Wi-Fi etc. as soon as I disable any internet connection it stops, so yeah, it's doing something really heavy in the background. When I look at my phone now that background activity have stopped (without me doing anything) and the battery does not drain as fast, even with mobile data enabled and on 4G.

So Apple most definitely are collecting some data at intervals when connected to the Internet. Next time it happens I'm going to connect it to my Wi-Fi and have a look at what's going on and what packets are beeing sent so one can get a clear understanding into whats going on.

Disabling mobile data and Wi-Fi completely and the phone runs with no battery issues at all, with Wi-Fi enabled it runs better than on mobile data enabled.

So yeah.. all in all.. they must be collecting something in the background while on the home screen.

I like the assumption people make here:

You report your "findings" in a polite manner and :

1) You become a peep who is dloading betas just for the heck of it

2) You are in panic and shoud be more calm..

3) You knew better it's a beta.... (of cours eit is ..this is why i am testing) you should know nnot to install beta (then why do they give it to us??)

4) You only own a device (just cause you are "reporting" issues) why do you have beta on production device? (and who told you this is my production device?)

5) It will be fixed so calm down (well i am sure it will..... do you really belive i expect ios 9 to have this battery life??)

6) My favourite one... why don't you test like everyone does? Plugged in into the computer so nop worries about battery life!!!! (Yeah like MOBILE devices now have to stay plugged all day.... and of course if you have a training app under development.......who does't train with a power plug behind his back??).

Again to all the "haters" please relax..and calm down..We know it is beta, we know it will be fixed and no we are not in panic! we just report findings and sometimes look if the issue might be a device specific issue...after all we are here to test..... oh and we are not all 12 years old playing Angry Birds.. some of us do work in app development.

Have a good day 😉

On topic, i had to revert to iOS 8.3 simply because i cannot live with this battery life (on a testing device) hopefully i 'll be able to test on 9 beta soon.

This is happening to me also

it's true! The battery it's draining very quickly and with certain condition the iPad Air 2 right side is really hot!!

It often happens when using with safari with some sites.

I believe that we should give priority to this issue on all other!!

Agreed 100%. I have run every beta of every version of iOS since the beginning. This is without question in the top 3 worst in terms of hosing the phone. Im not here to whine about it though... Im here to see if anyone has come up with clever solutions that I can reproduce and submit bug reports.

Many people on MacRumors are reporting obscene amounts of data being used by the beta, so mobile data is likely the issue here, especially with people saying disabling it fixes the drain.

Same here. Had a phone call with speakerphone and the phone was plugged in and the charger didn't keep up. With a gps app going and the screen one, it was going down by around 1% per minute.

Hey Andrea. Yes Its terrable on both my 6 plus and ipad air. I was hiking with my Dog for a couple miles and she went swimming and two hours later it was 60% left. I posted facebook videos and texed stuff too, but as with most Betas the first Beta is terrable for battery life. I cant revert back cause im using Watch 02 and I cant go back to 01 on the watch and BTW that battery life took a hit too.

How to Re-installed ios 9 to ios 8?

My usage and standby times are the same. 4:48 for both, 57% batt. Turning off mobile data did nothing. Fresh install on iPhone 6. I will be installing the beta again with iTunes overtop of my current install when I get home to my Mac. I remember when flashing Roms on my old droid, sometimes it helped to flash it a few times if there were issues.

This is not my experience with other Betas from IOS 5 on... my phone does run hot, (64 GB iPhone 6), and was dead after 6 hours. I also sent a message to Step Tracker, and he has fixed the half count on IOS9 as of this date. One thing to note: the steps did not count after the battery went dead this monring. I have been running it since day before yesterday as well as El Capitan, which seems much more refines.

Every Version x.0 Beta 1 for the past 6 years has been heavily instrumented. The instrumentation always causes battery drain.

(I guess the word s*ck is verboten on this board? Even if it's properly used? Wow.)

Same thing for me. Have 6 Plus and was experiencing almost 98% battery drain over 18 hour period with no use. Re-installed the update over the first one and my phone is still at 100% after a couple of hours of no use. So, it seems to have helped. Will know in a few more hours.

I also found that turning off nearly everything in General/Search (except for Applications and Contacts) and flipping off Siri helped. I was getting 1.5 hours of battery performance before. I'm now at 9 hours with 48% of my battery still left on the iPhone 6.

Same here, but better than iOS7 beta.

I have to bring the charge with me all the time.

I wonder when People will realize to not install the beta os on their main device. The PUBLIC beta is the user experience test run. dont expect to have a battery life on a dev firmware.

So a tester MUST have more than 1 device? I mean again the assumption that all people here are NOT developers? Macrumors users are the target of Public beta, iOS 9 beta and ths site are "designed" for developer...who guess what? might have only one device and want / need to test their app in iOS9 😉.

I am trying to figure out....if this is so bad and people need to wait for iOS 9 public beta .... why would they release it??? (oh right ..for testing....and that's what we are all doing!!!!).

I've been dumping the communication on my iPhone with tcpdump and interestingly when on the homescreen and doing nothing it does not communicate anything but the spinning wheel besides the operator logo starts as soon as I go to the homescreen (only at certain times in the day, from time to time it stops). During that it does not connect anywhere which I first thought. Disable mobile data and Wi-Fi and it stops completely. No more background process going on without an Internet connection. So it does something in a background process when connected to the "Internet" even though it does not transmit something. And during that background process my phone runs hot. Disabling mobile data and it cools down and stops with the battery bleeding. Just something I've noticed so far.. So now I use my phone disabling mobile data and Wi-Fi and when needed I enable mobile data to check mail etc. Just to see and monitor what happens.

Hey, I'll try to iOS 9 and noticed that the battery life is short. Fully charged at 100% and I also used 2 hours and charging has fallen 80% very quickly. On the iPhone 6 Plus. Hopefully, this battery life is improved after repairs 🙂

Now I've been able to run my iPhone 6 128GB with iOS 9 beta 1 for 40 minutes straight in standby mode (just viewing some e-mails from time to time, mobile data enabled, all background stuff disabled with not even 1% loss on the battery. Battery saving mode is also disabled. Don't really know what I did.. All I did was viewing the log files through the device viewer in Xcode. Disconnected the cable after a while and ended up where I'm now.. Before viewing the logs in Xcode I rebooted the phone also. But I did not change any settings in the phone from where it was before so I don't really understand what's going on

Soon it's actually 50 minutes without any battery loss.. still at the 97% as it was when I disconnected it from my Mac. Seemingly the background activity going on before on the home screen also suddenly stopped.

I'm going to spend my weekend looking into this matter a bit deeper, just for the pure fun of it

Well, flashing the update overtop of my fresh install fixed the matching standby and usage times. I will report later today if my battery life has improved.

Same here, i went to work looked at my phone on my break after 5 hrs phone was dead 😕. was not even using it.
