My previous XPS 13 from 2016 was suspending properly but now I cannot suspend my "laptop" for more than a day (it will die) or store it in a bag (it will become lava). Hibernate does not work either.
I'm learning with this thread that it also happens on Windows and I'm struggling to understand how Dell could decide to sell "laptops" at this price and not test one of the most basic features of a laptop.

I’m running 9310 with linux kernel 5.14.3 for the QCA6390 support as my laptop is the Windows edition.
It's because Intel have been incrementally removing support for s3 sleep, it's completely gone in the latest Tigerlake chips.
Linux s2idle support for modern Intel low CPU package power states is still pretty rough which is why you'll get a good chunk of power drain still.

And if you want to dig into what happening in s2idle, https://01.org/blogs/qwang59/2018/how-achieve-s0ix-states-li...
(I've just seen the last posts on that thread and will give it a try)
- short suspend time (it can't really stay overnight when suspended with a full battery)
- sometimes it wakes up and overheats in the bag
- very short battery duration when unplugged
Apparently I'm not alone, and even under Windows it's a generalized problem; and when you look for solution on Dell's forum you find this FAQ, which tend to say XPS are more foldable desktops than real laptops.
