I just got the wireless charging back and it charges, but while charging it lights up the lock screen and beeps about once every minute or two ("wireless charging"). It does this on two different wireless charging pads. The only way I can stop the sound is by turning the ringer off. I cannot find a way to stop the screen from lighting. This makes wireless charging on the bed table impossible, as the phone wakes me up. I tried using blocking to stop all notifications, but it does not stop this behavior. How do I turn off the beep and the screen wakeup?
