On Debian Sid with a Lenovo Thinkpad T14s AMD gen3 when I'm closing the lid it supposedly goes into suspend / #s2idle. But I have the feeling that for a month or so it's not working properly anymore. I'm losing ~20% battery charge over about an hour.
Guess I'll try a fwupdmgr update. It actually does mention some fixes for "Modern Standby" (ak. s2idle?).
