Extreme battery drain in IOS 7- iPad Mini Unusable after Upgrade
I updated my iPad Mini Wifi (32GB) to IOS 7 and within a few hours the battery had dropped from 99% to 5% at which point it turned itself off, stopping all running applications I recharged it overnight and unplugged it at at 7 AM and by 5 PM it was down to 28%. I was not doing anything with it at all. It was asleep all day doing absolutely nothing.
Prior to the installation of IOS 7 its battery life was excellent. Now the device is unusable.
I have also updated an iPad New Model (3) and an iPhone 5. Battery usage on both is normal.
I tried using the Mini while it was connected to its Apple OEM charger and it started going backwards. It went from 34% to 32% in a couple of minutes of use. It's barely charging with the cover closed and the screen off. Something is draining the battery almost as fast as the charger can fill it.
Does anyone have a fix for this that does not involve turning it into a brick by disabling all the radios and applications?
