[AC Question]

I purchased the wireless charging back cover for my Note Edge and the Samsung Wireless charging pad. When I place the phone on the pad at night, the phone appears to be charging correctly. However, in the morning when I wake up, the phone only charges to 70% and stops. I then can pick the phone up off of the charger and then set it back down again and the phone continues to charge to 100%. Is there a setting somewhere that I am missing? I really like the convenience of a wireless charger, but would prefer to start the day off with a 100% charge.
