Since installing the first iOS 9 beta, many users are experiencing abnormally quickly-draining batteries.
Users from /r/Apple, MacRumors Forums, and elsewhere report it’s difficult to get through a single day of normal-to-light usage without recharging, with battery drain continuing without use. While this is the first iOS 9 beta and some poor battery life is expected, user reports seem to indicate this is abnormal for even for iOS betas.
Reports indicate that iOS’s Settings app shows a large percentage of battery use attributed to Home & Lock Screen, despite statistics showing a low time on screen. Some users theorize this is because of lack of optimization with iOS 9’s new Search features with Siri suggestions. Other users believe that iOS is ignoring Background App Refresh settings, leaving 3rd party-apps unoptimized for iOS 9 running rouge in the background.
In my third day of iOS 9 beta use, my iPhone 6 has been below 50% battery every day before lunchtime after a full charge overnight. There seems to be no difference between using iOS 9’s new Low Power Mode or not.
Same here, I went out last night at 5:30pm with 100% charge with very light use 3-4 hours later I was down by 40% its crazy. I hope there is an update soon, or I might need to downgrade
I totally agree with this, I my phone was at 100% at 8:00am the other morning, and I went back to sleep, and then I woke up at like 12:00pm to it at less than 30%
Same here, I started with 100% in the morning around 10 am. By lunchtime 3-4 pm I charged it again. Around 7 pm I had 50% I then charge my phone in the car heading home then within 3 hours my phone was dead. not good
The battery drain is clearly an issue. I considered downgrading until the next beta is released, but I need iOS 9 to pair with Watch OS 2. Running in Low Power Mode appears to help a lot. My iPhone 6 Plus run pretty much like it used to with 8.3 in terms of battery usage (maybe a little worse, but not bad at all) with about the same overall performance. I can live with it for sure. It’s beta 1, so it will only improve with future releases.
Mine was so bad I’ve decided to downgrade and try beta 2 when it comes out
my battery is usually 100% when i start my day and in the span of 12 hours may get to 35 with normal use. with this beta, my phone was at 99% 6 hours ago, and it’s already at 20%, I’m not complaining It’s a beta IOS8 was bad for me as well so i expected it. but it definitely is significantly worse than most of the prior betas battery managment.
The same thing with yours guys , hope beta 2 fix it , because the battery is the main problem for the phone , but when beta 2 come out ? this is a question
It’s the first beta…don’t complain about all the bugs and battery drain issues on the first build of a new iOS version. For fucks sake that’s fucking retarded.
If it is your main device don’t install the beta! I have four iPhone 6’s. I have it installed on one.
Bravo, you are our hero! /s
i guess i have charged my iPhone6, 10 times in last 4 days !!! its crazy i have to charge 2-3 time in 24 hr time.
I hope apple will fix this soon with iOS9 beta2. I think I will shift back to iOS8 tomorrow. :[
but how to downgrade it ? via itunes? please suggest me on babariasandip@icloud.com
Yes, you have to downgrade using iTunes. Just download the IPSW for the latest version of iOS 8.x and go into iTunes and while holding down Shift+Click on Windows or Alt/Option+Click on Mac click restore. This should bring up the IPSW browser. Just select the IPSW you just downloaded and the rest will be done for you. Best of luck!
Hey it’s a beta, not made for everyday use…
It’s sad when the battery life is this bad considering that it’s supposed to be way better than 8.3. They have so much ground to cover, that I don’t think the battery life will actually be improved with iOS 9.
Or you’re using Beta 1 of incomplete software…of course it’s not going to run as well as a GM. Good grief. This happens every year…
When you’re developing software and after a years work, the first beta is way worse than your older versions, you’re doing something wrong. Furthermore, i find it a long shot to add an extra hour of battery over iOS 8 when they can’t even get the same performance even at beta 5…
Geez, off course its draining faster. On the dev beta there are all sorts of logging and debug tools running in the background. And let’s not forget that it’s buggy in general.
And yet you don’t put a caveat that non-devs shouldn’t install it anyway…this happens every year. Beta 1 is always about feature input and battery life suffers because of it. That’s why they are doing a public beta later on, and not right off the bat. That’s the one normal users need to wait for. Good grief.
generally all iOS beta 1’s i’ve experimented with have drained battery life. It’s to be expected. Nothing is really optimized yet and most of the apps aren’t even updated to function properly. On a separate note, I’ve not seen anyone mention that the “News” app isn’t included in the Beta 1 release (at least I’ve not been able to find it).
The “News” app isn’t available yet, neither is Apple Music, Loyalty and rewards cards in Apple Pay/Wallet. I’m excited for those to be released though!!
Turn on battery saving mode all te time, it works for me
i charged my phone to 100% before I went to bed a couple night ago. I woke up and it was at 31% to I had to charge it again
The find friends app seems to be draining quite a bit of battery, now that it is a required app it may be running more often than it used to. One of the battery apps report it is using just over 5 mAh/min, podcasts as using 4.5 mAh/minute, and iBooks at 3.4 mAh/min. I don’t even use podcasts or iBooks, so I would guess there are some background tasks apple will fix up soon enough.
Reverted back to 8.3 because of the battery issue. Went to bed at 51% and it was dead when I woke up :/
hey there, the issue/problem (what i found) is, that you cannot close the apps.
so, if you close the app with the slide up gesture it only kills the view on the “task manager” but still runs on background.
so, how to check or qucikfix?
just restart your phone and open the “task manager” again, you will see that all the apps you have “closed” is still running.
now you can close it with success *slide up gesture*.
but if you open a new app and try to close it again, it will only kill the view again!!!
hope it helps to pass the time for the next iOS9 fix :)
SaSame problem here. iOS 9 drains the battery very fast. I think the phone jumps ssilently to the unlock screen and that makes the battery level for that part very high.
Yes. This is a Beta version. But, this is probably the most severe battery drain I’ve ever had on any beta OS. I was using Maps for navigation with my phone plugged in and the screen at 50% brightness. It still dropped 10% in 30 minutes while PLUGGED IN. That’s pretty crazy. But. As it’s been said… Don’t put it on your main device if you’re not willing to risk these issues. =)
My Apple watch with 2.0 is just as bad..doesn’t make it thru the day
Yes, I’ve also felt this, it kinda sux :(
This is happening for me to on an iPhone 6 Plus I charge my phone to 40% and leave it on standby in my pocket for around 6 hours and it’s on about 13%
I’ve been experienccing some serious battery drains too. I work in a hospital with 12 hour shifts. I noticed that my phone dies a lot quicker than when I was in iOS 8.3
Glad to know that I’m not the only one experiencing this problem. Hope they fix this soon because I like this new iOS. Specially with the new fonts. It’s very refreshing!
I’m on iPhone 6+ by the way.
I was under the impression “Low Power Mode” was intended to stop the device from going the drain under 20% – however after reading the other comments in the thread – I enabled it and haven’t lost any power at all for nearly an hour – very encouraging.
Same for me: 100% fully charged in the morning. without any significant use 17% at 5pm.
Another user suggested that they installed ios 9 without restoring from last update. Essentially as a new phone. Has anyone tried this workaround to fix the battery drain issue?
Hi. I had same issue with iOS 9. Increasing brightness above 50% somehow helped me to maintain battery life. Its not that great though, but still better than before. So if you keep your brightness below 50% and turning on battery low power mode will decrease the battery more somehow. And one more thing…, when you receive notification try to get rid of them. If they are on your screen and you leave them like that, it will drain you battery super fast. Just clear them.
Hope that helps. Thx
Seems to help, but not entirely.

“1. Completely disable iCloud Backups on each device running iOS 9 Beta 1 (Use iTunes to Backup and restore devices for now.)
2. Disable iClkoud drive (if you enabled it) on each device running Beta 1
There appears to be a SERIOUS problem with the API handling backups to iCloud or some sort of permissions issue with the data being written to iCloud. This likely went into effect during the update phase that indicated “iCloud data is being updated”. (During the first Beta 1 load.)
This has confirmed to entirely resolve the “somewhat unpredictable” and extremely high rate of burn on the battery for this beta on iPhone 6, iPhone 6 Plus and iPadf Air 2. There is no reason to believe other affected devices will respond any differently to these changes, so we encourage other developers to try them asap. Apple should likely address this with the next update, when we can resume use of iCloud as normal during testing.
NOTE: iCloud data used by Third Party applications and other data like Calendar, Contacts and so on, does not appear to be causing any issues with battery usage, nor does there appear to be any data corruption. However do proceed with caution if you are using iCloud for your beta application development.”

Yes same here 98% charge when I was going to bed only 12% when I woke up
switched back to 8.3: 100% in the morning, 80% at 8pm without significant use. –> back to normal.
Same I had 100% charge 2 hours ago and now it’s below 60% charge
Sounds crazy, but guys try this, turn your auto lock to never. In 20 min no % loss as yet
omg the battery life on the IOS 9 beta is just terrible I literally was at 13 percent at 12pm after just texting and listening to music moderately. I charged my phone to 100 percent the night before I really hope they fix this in beta 2. I cant downgrade because I am running watch OS 2 :(
Has anyone been using beta 2? Has this been fixed because I had to revert out of beta 1 which was an annoying process I’d rather not repeat…
Is the only way to downgrade is to reset the phone?
No problems here. I have problems draining my battery so that I can test my new portable charger.. It must not be a universal problem
Yep, I charged my iPhone 6 Plus overnight to 100%, and unplugged it at 8:30, but went back to sleep. When I woke up later at 9:00, by phone had SOMEHOW reached 30%.
iphone 6 dead! not charging anymore…just installed iOs9, it drained all the battery twice and in the second round it didn´t charge. I tried hard reset, change cables, connect directly to my MBA and still nothing…. I am lost :-( I never imagine how addict I was to my iphone…. :-( anyone please help!!
Had same issue happen to me. Installed iOS 9 on my iPhone 6 Plus and battery usage was so bad that I had to downgrade back to 8. I hope they fix this soon.
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 😖
installed iOS 9 final on my iPhone 6 and the battery life is horrible. I hope they come out with a patch soon. It seems Mail is using 30% of my battery constantly. FB and Home Screen are using 13% each. Thats over 50% battery usage right there.
I went to sleep, woke up 7 hours later to a dead phone. Thankfully my alarm went off right before the phone turned itself off. it was at 100% when I went to lay down, too. :< I think I might finally need to upgrade to a new phone.
Hello guyz,
– Upgrate your iPhone with new iOS version 9.0.2
– Now try to Reset All Setting in Setting-General-Reset-Reset All Settings (Dont worry..Your all data will be safe)
AND YOU HAVE FIXED BATTERY DRAIN.
