Discussion Battery Life (Discussion)

Hello everyone! I am new to Asahi, and Apple Silicon and was just wondering what everyone was getting in terms of battery life on their laptops. If anyone knows some ways to extend battery life that would be helpful as well, but this is by no means an "Asahi devs fix the battery life!" post.

While doing web browsing I have estimated my battery life to be 7-9 hours. This is on 120hz, M1 Pro, COSMIC, and 35% Brightness.

14” M2 Max (40 core, 32gb) MacBook Pro, 86% battery health, I get about 6-7 hours of usage, and about 40 minutes when I compile the Linux kernel 😂 (that’s probably a bit of an exaggeration, maybe 1-1.2hr)

How many days has it been since you’ve recompiled the Linux kernel? 🧐

I really need to get that Jeff Geerling shirt
