Battery Charging Very Slow or Not Charging – iOS 7
Many users are experiencing a drastic change in the speed of fully charging their devices since the iOS 7 update. Some report not being able to fully charge their iPads after leaving the device plugged in overnight!
The Issue
It appears the iOS 7 update has increased the power demand of the device. This means that the normal power sources users used before to charge their devices may no longer be powerful enough or compatible even though they were prior to the update. According to a genius bar rep, the iPads are not designed to be charged from a standard USB port or from an iPhone power adapter.
The Fix
Please try using the original wall charger that came with the device to charge. Many users report success after switching to an official 12 watt charger. The iPhone power adapters are 5 watts and will charge your iPad very slowly. The iPad chargers has more than twice the iPhone’s power at 12 watts. Off brand chargers varies in power and are not recommended; it has also been reported that Apple has disabled functionality of many third party devices since the update. Please use an official 12 watt Apple charger to charge your device. Please test that this works for your device (borrow your friend’s charger) before you go off buying a new charger. You can also try resetting the device by holding the power and home button until the Apple logo appears.
Tips on Charging
