I have managed to achieve the same battery life, down minute differences in the single digit either side, between macOS and Linux on a MacBook Air (which is a simple all Intel machine). I think the problem is that most distributions ship with no Powertop or udev rules, plus lots of unnecessary services and devices on by default. One really nice thing Apple does is optimizing Safari for battery life. My comparison was Firefox on macOS vs Linux. With Safari, I'd get 20-30 min more. I bet Firefox and other programs would benefit from some black-box GCC/LVM flag optimization to improve battery usage.

Firefox on Mac's big battery life problem is apparently lack of integration with the system compositor. There's a fix in the works for this. Although I expect safari will still be better in this regard. Safari is pretty impressive.
