Iphone charging issue

[joeg679]

Lately when I have my 5s plugged in and charging, it'll randomly wake up and make the sound that it make when you first plug it in. It'll do this mostly when it's already at 100% battery. Does anyone know what the issue is? Thank you

This can happen when it momentarily loses full contact with the charger, or if the charger is not a genuine Apple charger (or "Made For i" certified charger). It can also happen if the cord is damaged or stretched. Try changing cords first, unless you know you have a "cheapy knockoff" charger.

Thanks, it's a real apple charger, but I'll try switching cords and see if that helps.
