For light usage my Thinkpad X1 Nano Gen 1 is about the same or a bit better than Windows (~6 hours usage) under Fedora with KDE, which has TLP-like optimizations baked in. It might not technically be as optimal for the hardware as Windows is but the system being much more "quiet" (Windows is always doing something in the background) likely makes up the difference. I'm hoping that the next generation of AMD/Intel efficiency-focused laptop CPUs improve this dramatically though because it feels ridiculous that my M1 Max MBP gets better life not in power save mode while doing "real work" than I could ever get out of the Thinkpad with a light workload in power save mode. If this turns out to be true I'll be trading the Thinkpad in for a newer model.
