iOS 8.4 Battery Life

I restored from a backup up and that resolved it for me. I originally did a OTA update as well.

Since doing the update my battery life has plummeted off a cliff, On third charge today now and I've barely used it. I read a whatsapp meassage earlier and it took my battery from 58% straight to 42%

When I left for work this morning my battery was 98%, 10 minute drive to work then read a couple of emails on my phone and it sent my battery to 52%!!!!!!

Whoever has been testing updates for the last few years does not do a very thorough job....

My latest backup was to icloud over night so already has the update on the backup, and my last backup on the pc was ages ago.

I restored from a 8.4 backup via iTunes. First update was OTA.

Ok thanks Symp, I will give it a try, my update and backup were both OTA as well. Seems odd that restoring it to when it already had the issue will resolve it, but hey you never know with apple products these days!

I think the issue was the OTA update.

Hallo togther,

did the restore work for someone ?

no luck with the iCloud rest or log off. I was basically told to get lost because their diagnostic scan found nothing. I can boil an egg on my phone after 3-5 mins of usage and battery drops 15-25%. This is insane and they won't replace phone with new retail unit. Saying goodbye soon after owning every iPhone since 2007. **** you apple

I concur. 8.4 drains battery like a kid drinks a milkshake. Down to 50% by lunch. Fwiw, I did not do OTA. I used a USB cable to perform the upgrade.

To fix your phone go to settings then general and go to the bottom and hit reset. Then select RESET ALL SETTING.

This will not delete anything real important.. You will only have to connect to the wifi again do your finger prints/password and your background may change the rest will stay the same.

HI. Try to follow the instructions on this page in order to maximise your battery life: https://www.apple.com/batteries/maximizing-performance/

Try to reset your device. This won't delete your data stored on the phone.

• Press and hold the Sleep/Wake button
• Press and hold on the Home button
• Keep holding both buttons until the display turns off and back on with Apple logo on it.

You may also try to reset all settings: go to Settings - General - Reset - Reset All Settings

You may also try to follow these steps:

1. Navigate to settings/general/ battery usage. Check the applications. This will show you which app eats up your battery.

2. Turn off iCloud keychain: Navigate to Settings/ iCloud/Keychain / turn it off.

3. Limit apps activity on the background: Navigate to Settings/ general/ Background App refresh/ turn it off for each application which uses to much power.

4. Disable auto brightness: Navigate to settings/ display and brightness/ auto-brightness. Turn this option off.

I have the same problem , I'm going to restore the 8.3 😟

I was able to save a ton of battery by disabling "sync playback information between devices" from within iTunes on my PC.

Have been facing the same problem. the only thing people come up with is battery saving tips. this is a real issue people. i have restored my phone atleast 18 times in past five days. the problem is stuck like anything. have called support and after running diagnostic they say that hardware is fine. i have read a post somewhere where a GUY took his phone to genius bar and they were unable to resolve the issue and said to the person we cant do anything for you.

APPLE PLEASE ADMIT THE PROBLEM AND LET US ROLL BACK. WHAT SHOULD WE DO WITH BRICK PHONES.

How are you going to revert when apple is not signing the roll back to IOS 8.3. if they are then kindly post for the sake of other users.

Its kind of absurd to suggest that we should limit how our iOS device works to compensate for an update that clearly reduces battery life by a dramatic amount. It seems clear that 8.4 needs an update to correct this flaw, whatever it is that is eating up battery life all of a sudden.

same thing happening with me too after upgrading to 8.4..last night my iphone was at 67%, I switched it off ..checked in morning and it was 0..not even turning on...feeling frustrated 😕

....updated via OTA. Will try backup and restore today....let's see how it goes..
