Sort of, but for very specific purposes. I think PopOS or System76 have kernels that use different CPU schedulers, but I don’t think it affects battery life, just desktop “responsiveness.” Make sure your CPU is hitting the lowest C states. Make sure your NVMe drive can do so too or if it’s blocking the CPU from lowering its C states. Linux might be less energy efficient on newer laptop hardware because it lacks vendor optimizations that Windows has. Tried, been there. If you’re trying to optimize I’d recommend TLP/power profiles and throttled.
