I have a charging case that i got within a few weeks of the iPhone 5 coming out from China... it has worked great for me... I will have to plug it in to my iPhone 5 with iOS 7 and see what it does.
You guys have jinxed me with this thread. I have a CERTIFIED Apple-made 30pin to lightning adapter I use to charge my iPhone in a radio dock. Worked fine for the first two days. Last night, got that message. Disconnected it a few times and then it charged. More than a little annoyed. Hope it was just a one time screwup.
