iPhone 6 8.4.1 Battery drain fast, Frozen when force close apps

My iphone 6 was running iOS 8.3, I had the phone restarted as normal, then the phone began to drain battery like crazy, almost 1% in every minute or two, and the phone getting quite warm. I tried to force close some apps and the phone got frozen until the phone return to standby mode (screen off). The phone is getting difficult to recharge at the same speed as normal when the phone is on (perhaps the battery drain way faster than normal).

I have the phone updated to iOS 8.4.1 (reluctantly), and nothing change. Now I have turned off lots of apps / functions running hehind the scene, including email fetching, and the power drainage seems stablized in a relative accetable level and the phone is not as warm.

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

http://www.idigitaltimes.com/ios-82-battery-life-problems-how-fix-quick-drain-is sues-iphone-ipad-and-ipod-422229

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.

Thanks heaps! I found out it is the iCloud Keychain drains the battery and running my phone like crazy. Funny that I switch off the iCloud all the time except allowing it to backup whatsapp.
