battery drain ios 8.4

Go to Settings>General>Usage>Battery Usage and you will see what the offending app or apps are. That should help you troubleshoot what the issue might be. I have an iPhone 5s, and actually with iOS 8.4, I've seen an improvement in my battery usage statistics. Used to be that I never saw more than 3% per hour drainage with moderate to heavy usage, now it is below 3% per hour. Once you find the offending app or apps, you can try correcting it, depending on what it is. Contrary to what many people will recommend, I leave Wi-Fi on all of the time, Bluetooth is on, as well as a number of location services.

Did you update via OTA or through iTunes Thomas ?

If you did the update via WiFi, backup the phone, restore it via iTunes and get the iOS 8.4 software installed via iTunes as it's a different file and sorted the issue for me in the end.

Hope it helps ...

I have the same problem with iOS 8.4, but with a 5C. I've tried switching off iCloud, location services, wifi, bluetooth and background app refresh. I even left it in flight mode overnight and the battery still drained in about 5 hours. Will try reverting back to 8.3 tonight.

Should add that my upgrade to 8.4 was through iTunes.

Apple does not provide a path for downgrading. If you are getting that kind of drain while in Airplane Mode, you have a process stuck. You need to restore the device as new and test before adding any content back. Something corrupted with the installation of your update. It is not the update itself, however restoring the device as new will download and install a new update.

Yes, I quickly discovered that downgrading wasn't an option. No processes stuck as I've rebooted a few times. Have restored the device and it's still a problem. Have also noticed that it's extremely slow to recharge, so I suspect it might be hardware-related. Thanks.

I Had exactly the same problem, as well on my iPhone as on my iPad. After some fine tuning of the settings, still the same problem.

Solved the problem by taking the next steps :

1. Made a full backup, via iTunes.

2. Re-installed, via iTunes, the IOS 8.4 software (full and with factory settings !)

3. Did a check of the basic operation/working. OK

4. Reloaded my apps and settings.

Both, Iphone & Ipad are working properly now !!

The problem of the bad working IOS8.4 upgrade (and the upgrades before) has to do probably with some incompatible soft/hardware and only for some devices.

A clean install with the latest IOS version solves the problem.

Agree, this is a time consumable solution but it is worthwhile to do.

Good luck !

same here bro.. ios 8.4 is killing my battery..

I have had the same issue on my iPhone4s I think the culprit is the new Apple Music service - Try logging out of the service in the account setting and see what happens. Did the trick for me and that was after trying virtually all the restore options and a trip to the apple store - that latter at least confirmed to me that my battery was working fine so I knew to keep persevering in the search for an app that was constantly updating info. In theory the Music thing would eventually finish its updates, but I use Spotify. This pain in the backside has further confirmed my commitment to that platform.

I am having similar battery drain. My highest usage is the Home and Lock Screen. I use the stand by button all the time to minimize the time that screen stays displayed. That isn't an app either. Why would that screen drain the battery? Thanks for your help!

There is no way any of these people have better battery life with ios 8.4! low signal issues are the worst now! I have to keep it out of my pocket and hold it in the air to get a good signal now. Not what you want to do with an iPhone the darn thing should just work, but they blew it again with an update. They better come up with a fix soon or android here I come. A nicer phone and changeable battery how can you beat that. Some people might like the arrogance of apple but I had my fill. I want a phone that works! I had to shut instant messaging off because nobody understands how to use it and I do not want to get every ones reply's to every group text. why isn't there a reply and reply all option like we are use to in emails? I could go on and on but I will let it go and see if they fix it soon.

There are some tips to improve battery life time for ios here.You can read this article.

Hope it can help

It has nothing to do with tips! I have tried them all since I have had my phone. iOS 8.4 rendered my phone useless. Time to step away from Apple products, I cannot deal with this behavior

Customer support sent me down the same route for my iPhone6. the battery still drained quickly after the restore to factory settings, but after 30 hours, it stopped draining on its own and is back to normal like before the iOS upgrade. I had to reinstall my corporate email after the reset. All a painful process but can at least resume happy iPhone use

I Am having the same problem too and mine is iPhone 5s. Anyone can help?? Thanks

HOme and lock screen drained battery

No there is no Help! I have been told there is nothing wrong, all is well. I do not use Music & it is turned off as well as can be. The music uses almost the same amount of battery as the GPS & sometimes more? How can this be all is well.

Zero & I mean absolutely ZERO help! I have reset to factory settings 5 X reset to factory settings 5 X replaced the battery 2X. I used every trick in the book to save battery life but it always comes up with Music! Why?? Also after updating the software the phone will not power off & stay off. It turn s off then in a minute or so boots itself back on with music draining the battery even more. iPhone 4s 64 gig. All battery issues started with 8.4 then continued with 8.4.1.\

What a joke Apple

Ok no fire truck hen where is my help? I get software that does not work & makes my phone useless! Were is the help?? If this is a help site then get me some help!! I sometime wonder why people get so mad? Well not anymore! IOS 8.4.1 is nothing short of the most ridiculous piece of so called software ever!!
