Yes I get that also. I have Yinjeng receiver and one white ebay charger pad and one LG charger pad. With LG pad it's charging till 100%, with the ebay pad it goes to 100% and after I lift the phone I still have a green battery in the left side of Notification bar. And indeed I can use the phone and it stays at 100%. Only a reboot solve the problem.
