this problem isn't entirely windows-related/driver-related either. even with the very last-gen 2020 macbooks with ice lake, they still have a pretty significant amount of discharge while sleeping. and apple is running their own OS tuned to the exact hardware with the ability to get whatever source they want for drivers (and again, the will to perfection to use it).

i would have to measure it but it probably is at least 15-20% a month which is moderately crazy compared to apple silicon. i've picked up a MBA and it instantly woke up and it had lost like 2% in the month or two since I replaced it.
