It helps, but its far from the whole story. Asahi Linux developers have reported exceptionally good battery life on Linux. IIRC they were getting around 7 hours before the GPU driver was implemented and it was continually burning ~60% all-core CPU just to render.
I believe the hardware itself (and the firmware) handles a lot of the power management. Aside from which, Apple's CPU cores do seem to be straight up more power efficient than anybody else's.
- askonomm 3y ago7 hours is still quite a bit below the 20-22 hours with MacOS though. It may seem a lot given how bad batteries are on non-apple computers, but it's still less than 1/3 of what it could be.
- shepherdjerred 3y ago7 hours is incredible if the CPU was really at 60% sustained usage.
