Ask HN: Is hardware optimised Linux possible?

I always read about macOS running harmoniously with Apple's hardware because they are "optimised" for each other. I am not gonna lie, I don't understand how that works, but I can vouch for it. I do find that a low-end MacBook Air feels much faster than a similarly-specced machine running Windows. Snappiness and speed, however, are not a problem with Linux. My issue with Linux is battery management. Running Linux on a laptop sucks for me. I have tried multiple distributions on multiple devices, and the only ugly thing about these experiences was the battery life getting hit drastically. I am speaking 50% battery life here. I want to jump on the Linux train, but I am too addicted to the battery life a MacBook offers me. I don't want to run multiple operating systems that change with context. I want to have one consistent experience regardless of the work I am doing. Is it possible to create the same harmony that Apple makes for its hardware and software to work well together with Linux? Is it difficult in the sense that it would require a huge amount of research and development in completely new hardware? Has it been done by anyone before? Are my questions valid at all, and not just naive babbles?
