Windows uses a lot of power just existing, so you can’t get any of the windows handhelds down to a low power consumption. I remember when the Rig Ally first came out, the verge tested it using 5-8w of power on the steam deck, and using 16-22w of power on the Ally. Some of that is the hardware (the Deck has a really power efficient chip for low power games), but a lot of it is windows.
These are both on the Lenovo Legion Go S. The significance here is that there’s both official OEM windows and official OEM steamOS for this device.
