I'm personally very interested in the "Low Power Island" and it's efficiency cores for it's efficiency cores.
S0 standby is pretty rough on high end high power laptops like my Thinkpad with it's 11th gen i9. I sometimes have power drain higher in standby than just normally on. If Windows is smart it could turn off all cores but the E E-cores and maybe make modern standby not so much worse than S1-3 standby.
The Low Power Island also has DLVR finally, but sadly the rest of the CPU doesn't.
Don't you? Instant wake is hella useful, especially if you are using a laptop as a laptop and moving between meeting rooms etc, constantly bumping between sleep and wake.
Instead I get 30+ seconds to wake from sleep, 1% battery drain per minute, and the random chance that it just overheats in my bag and crashes. At least on my Surface Pro and Intel U series laptops it's tolerable, but I'd much rather S1 standby for 30 minutes, S3 standby for 4 hours, before finally hibernating. Instead I currently get buggy S0 for 15 minutes, and hopefully it makes it to complete hibernation after that.
Bingo. MacBook’s are always ready to wake with little battery loss. Windows just … can’t do that ever. If phones can be expected to behave this way, computers have zero excuses they can’t.
Man, this is why my work laptop does that. It is an all around POS so I chalked this problem up to that. I didn't know that MS deliberately broke sleep. With this knowledge I've learned how to go back to regular sleep.
