I use asahi on a MacBook air, and love it. The battery life on sleep mode has been improving but it’s nowhere near the voodoo Apple does to MacOs. I recently installed Linux on my Asus machine and found the process and community to be really helpful, so maybe that’s an option for you. Check out https://asus-linux.org/
That’s awesome. My Asus uses a bit more I think but I never measured it. The MacBook air used to die in one day in sleep mode and now it’ll last almost two days, so progress!
