My guess - A software bug. Hear me out - one time I had the AVP logged in charging and put it into the case. It should be asleep. When I took it out later, it was warm.
Other times I had phantom battery drain. My guess is that the sleep mode isn’t activating, then while plugged in it will allow more cpu headroom, then combined with the cover being put on results in heat with no where to go.
