Unfortunately, that’s about as good as you are going to get.
The design parameters and architecture of the Windows/Intel platform package come from a completely different design ethos than ARM/iOS/Android world.
The “mobile phone” platforms have been pushed “up” for tablet devices and at the other end with Windows/Intel you have a desktop platform that’s been pushed “down”. In tablet form factor they superficially meet but the thinking and intended usage pattern behind the usage models is very different.
Windows/Intel is, at core, simply not built to be in “always on, but mostly deeply asleep” mode.
(This is not solely a Windows problem, incidentally. Apple OSX versus Apple IOS is in exactly the same position.)
TL;DR
Desktop derived systems and phone derived systems have fundamentally different core design goals and are never going to be directly equivalent, even if there are some surface layer similarities.
