A lot of Apple's battery life success seems to be due to the software—both iOS and MacOS. Android's only just now starting to kind of catch up with iOS on power management, and MacOS doesn't beat other laptops because they use giant batteries or something. I'd expect it to take 7-8 figures of focused investment in the Linux kernel and probably some significant mountain-moving to get peripheral projects (windowing system, init maybe, various driver vendors) coordinated and going in the the right direction to improve Linux's power management much.
Hell, even the Apple browser is more respectful of battery life than its competitors. Power draw seems to be considered carefully at every level at Apple, and it shows in their results.
