Same here. When I started working from home, I set up an external monitor with an HDMI-to-USB-C adapter. Whenever it's plugged in, my battery goes down about 4% per hour with the AC adapter plugged in.
- kosievdmerwe 7y agoAre you sending your power via a USB C adapter too? If you use one of these[1] then your laptop will charge more slowly than if you just plugged in the power directly.

- wingworks 7y agoI'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.
- TorKlingberg 7y agoThe 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.
- aaron_m04 7y agoMy charger is an Apple product; it was the lowest-price charger they had available ($73 after tax). Two components: * charging block * male USB A to male USB C cable EDIT: I just clicked your link; no I'm not using that. The cable is plugged into the charging block on one end and the laptop on the other end.
