I've only ever seen my laptop's battery discharge while plugged in via one of those USB-C hubs which allow PD "pass-through". But have yet to find one that passes all the power through.

The adapter claims some of the power for itself and downstream USB devices. I think it has to reserve power statically, so it's always claiming 5W or so.
