battery charge foibles

I got a newish appearing KEYᵒⁿᵉ advanced replacement in October for screen pop.

I charge always via a USB-c connected to QI receiver around back under an Amzer snap on placed on a QI charge stand output 5v 1a.

Occasionally I feel the device get warm and the charge stalls at once 72% and just now 93% ... I took it off, let it cool, put it on, and it completed charge to 100% with no heating.

Any explanation?

Try charging it with a correct power source directly to the USB port and report back with the results.
