Windows Phone 8.1 Battery Issues

[ALee Shoukat]

After updating my Nokia Lumia 620 to Windows Phone 8.1 My battery drains out so fast. What to do? :crying:

Go thru battery sense, there are a lot of apps running in the background that you can disable. I know some of the games are background battery killers.

Just make sure to install all your apps onto the phone instead of SD card. Installing and running apps from SD drains the hell out of the battery.
Worked in my case.
