I carry an M1 Macbook Air (for xcode) and an LG Gram 17 running Kubuntu for everything else (which is most of what I do). The Gram is probably the best laptop I've ever owned (it replaced an XPS-15) - it's bigger (13" vs 17"), lighter (2oz less than the air) and gets crazy life out of the battery. When new, the Gram got 11-16 hours of battery (it now gets 8-10 hours) under development load (i.e running a node app, a go app and a Django backend, plus support servers). The Air hasn't been used as hard as the Gram, but it's battery gets similar performance. On the power management front, everything works on the air. On the Gram, hibernate is disabled, and sleep works (I've left the Gram in my bag over a three day weekend, and it was at about 20% on Tuesday when I opened it up). I ran Windows for about a week on the Gram and it did got less than eight hours of battery. No idea why.

I've had quite good success with hibernate on Linux. It was a long time ago but I accidentally tried it on a laptop ~13 years ago & it just worked. The appeal was immediate- 3-5s boot/sleep rather than near instant but no battery drain! I had one laptop where the wifi would only come up every other boot, but that did eventually, after many years, get resolved with a new kernel. It's been really nice having no power drain on personal laptops! Agreed, I too see pretty excellent power consumption on Linux. The new connected Windows stuff looks so awful, unbelievable power drain. I hope it largely remains a Windows problem & doesnt Linux greatly. To be honest, 20% after a weekend is much less than I'd want.
