unfortunately asahi linux bare metal cuts batty life by 40% or so and doesn’t support external displays via USB-C. worse battery seems a very common theme for linux-on-laptop.
Yeah MacOS is better with Battery life compared to Linux.
But, compared to W11?
I guess it depends a lot. My Precision 5520 got an extra hour of battery on the 9cell varient. Thats about a 20% uplift from W11; but thats an old Xeon laptop now.
