When I have my MacBook connected to an external monitor through USB adapters, it does drain a little faster. I haven’t tested if my HDMI monitor connected directly does as well, but I’m sure it would. Any external monitor should require some extra GPU resources which means more energy which means your battery should drain faster. How much faster depends on lots of things.
