iPhone Smart Battery Case charging problems
I have the iPhone Smart Battery Case for the iPhone 6. I keep getting errors it is a not approved accessory. It charges, then stops as I keep hearing it ding. Last night the battery case was at 2% and phone was at 77%. I cleaned the contacts on both sides and no avail.
I have replaced it and same thing still occurs. It is not the case, it is Apple being Apple, as it charges fine on its own. It only has issues when charging when mated to the iphone at the same time. The iphone itself charges fine on its own. So therefore its either the lightning connector inside the smart case, or the iOS firmware rejecting it.
Why would this keep occurring? I want a real answer and not one that says see Apple because it doesn't make logical sense.
iPhone 6, iOS 10.2
