I consistently get 10+ hours. I'm currently using PopOS+GNOME and my typical workload is a combination of a web browser + development in terminal (vim) + Obsidian for notes + cloud sync + listening to music + IM (but not Slack ;) ). It is to say, the workload is rather low.
It is certainly not M1-like battery performance, but plenty for my average workday not to feel constrained.
My current laptop is ThinkPad X1 Carbon 7th Gen from 2019 with 1080p screen, 10th gen Intel CPU, 16GB RAM, I replaced SSD for a very fast Samsung one. The laptop has a rather tiny 51Wh battery.
