The new suspend mechanism is s0ix and it works quite well. My xps13 9310 (32gb version with the jank AX500) will even get to opportunistic s0ix with a recent 5.

The new suspend mechanism is s0ix and it works quite well. My xps13 9310 (32gb version with the jank AX500) will even get to opportunistic s0ix with a recent 5.17 kernel. When I originally setup this laptop, I found that if I left the intel raid storage crap enabled, the mvd module would prevent s0ix/suspend. Switching to AHCI in the bios resolved this. https://01.org/blogs/qwang59/2018/how-achieve-s0ix-states-linux https://01.org/blogs/qwang59/2018/how-achieve-s0ix-states-li...
