Cheapish (~$1000) thinkpad E14 gen7 (AMD) variant has battery life of >24h (reading/typing in vim). At least according to power meter, not that I'd read or type that long.

And everything works on it on Linux, even obscure things like fingerprint sensor, various bizarro Fn key combos, all the various HW accelerations (video encode/decode via vaapi), etc. I didn't find anything that would not work.
