As someone who has done this very thing, and is a lifelong Linux fanboy (I run Linux on literally everything else), I would strongly suggest you don't do this if you're using a Macbook. The losses on battery life are far too high to accept, and if you have lower specs on the Mac laptop, you will really feel them on most Linux flavours.

Why do people keep saying this? I have been on M1 Air on Asahi for the last 4 weeks, getting 8-10 hours daily. I see my wattage consumption on screen at all times, it varies between 2.5-3W when scrolling web and around 5W when actively working with apps. I see no difference between macOS and Linux! The only difference is the s2idle consumption but personally I don't care, besides all other modern Linux laptops have same exact issue, often worse.
On my Intel T14s 4th Gen I was getting maybe 5 hours, and that's already with heavily optimized setup!
