My Thinkpad X1 Carbon (gen 5) running linux can suspend for weeks without dying. There was definitely a window where battery life under suspending wasn't a huge problem in Linux, not sure what happened.

I also have a Framework 13 (11th gen intel) which has terrible suspend battery life (also loses 2-3%/hour like the newer AMD version)– I was hoping that the AMD chips would fare better, but it seems not.

For my all AMD ASUS TUF 16, I am having a great experience with sleep and battery drain. I’m running Nobara, a Fedora gaming spinoff. I can 100% treat it like my apple devices where I can close it and ignore it for several days, and maybe lose 1-5% battery over that time.

My understanding is that it being all AMD makes a difference, but I don’t know for sure.

My Framework has the same battery issues as OP.

My previous two Xiaomi laptops also held charge for a long time on suspend, though not weeks.
