how does the new deep sleep s2idle work compare to older gen of laptops?

some people reported that a night costs 20 - 30% of battery life on framework laptop (after they configured s2idle deep properly), but nobody cares to measure the possible battery life difference between s2idle deep and s3

edit: I have 11th gen i5 intel nuc, but I didn't check whether the deep sleep works or not since it's a desktop
