I'm using Framework with Windows and AMD and I have excellent hibernate/sleep time... It is really a Linux thing. I remember a post on reddit that claims that the Bluefin distribution has excellent battery life.
It amazes me how the legend of ARM being more efficient than x86 took hold. I'm not saying that we don't have a more efficient ARM processors BUT it has nothing to do with the ISA. What you gain with a simple encoder (ARM) you gain with code density (x86) and after that it is converted to microcode. You wouldn't gain more than single percent if any.
Process node is by far more important (5nm , 3nm, etc) and usually Apple gets access to them first. Also placing the memory in the CPU package also proved to be great for efficiency (case of point is Intel's Lunar lake that can last like forever) and last but the least is the intergraded GPU that no one seems to talk about and their respective efficiency (cause there are like 30 people in the whole world that can truly make and educated talk about them and their ISA)
