No, the eSIM itself does not drain the battery of your mobile device. It consumes the same as a SIM card when using cellular data. However, being connected to two networks uses more energy than being connected to one network. The same goes for using your eSIM (or SIM) for sharing personal Hotspot, this would naturally drain your battery.
