I have the 2022 X1 Yoga Gen 6 as well. I am not impressed by battery life. Watching a 4K movie can easily drain the battery form full charge.

The major issue is over heating. Unless I place some small item underneath it (think a lighter size) to make a 1 inch gab between the surface and the laptop it overheats to the point where it stops functions (e.g. movies starts to freeze up). With a bit a airflow underneath it this problem goes away. The casing can get really hot. Almost to the point where you burn yourself. Almost.
