Battery Discharges Overnight

my HTC One M8 is discharging overnight...it will go from 80% or more to 0% by the next morning unless I leave it plugged in. I have the power save turned on, the brightness turned down, the Bluetooth is off as is the Mobile Data. Don't know what else to look at or change. Can anyone help?
