Note, this isn't Dell specific - the loss of s3 sleep is coming from Intel and Microsoft. The idea is that S0ix is supposed to "replace" s3, but (at least on Linux) it's a horrible mess.
I have a System76/Clevo - ostensibly one of the better choices for running Linux - and S0ix at best drains like ~5% of my battery overnight, and at worst it doesn't work at all.
Some will quip that I shouldn't expect sleep to work on Linux anyway, but this defies my experience with S3 on Linux (which has "just worked" for the last decade for me) so this is a substantial downgrade.
Do yourself a favor and avoid Tiger Lake and newer if you care about reliable sleep.
Just got a i5-1135g7 system can't make ubuntu to wake up my screen. seems like it won't be fixed. and windows s3 wake is just very slow, need 5-8s to wake.
