The iOS 8.4 drains the battery super fast

After the latest update iOS 8.4 my iPhone 6 battery drain like never before from 100% to 10% in just one hour even if the data plan is off i feel this is the worst to happen with me.

I have been using apple form the start (Apple 2G to Apple 6)

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 noticed this too when I updated to 8.4, the battery drain is huuuuge.


I've got a bigger problem with it also breaking app store updates so I'm trying to fix that first.


Hope someone comes up with a fix for the battery issue too because that was my next urgent to do.


Don't even want 'Music'. Is this worst Apple iOS ever?
