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.
> The losses on battery life are far too high to accept,
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!
Impressive, that must be a recent fix then, and it's good to hear. I tried Asahi some time ago and it was about 3-4 hours on average. I am still running Linux Mint on an old 2015 Macbook Pro and had to make some major power management tweaks (preventing it from _ever_ boosting up from base CPU and GPU frequency) to get close to the battery life I had before.
Definitely not 5h, not anymore. I just got off the train after working on my laptop for 3.5h, connected over wifi to the internet, browsing, searching files, etc., and ended with my battery down to 65%. I have no complaints, this is as good as it gets for Linux users. I think it's worth noting that Linux and its stack is probably most efficient OS nowadays, performance wise, so while not totally optimized for hardware, the software gets extra 10% or so over macOS and it might be showing.
