@James,

At least locally feel free to change the policy to "deep", but it's actually
intentional to be using s2idle on this machine with the latest upstream kernel. 

Rather than swing the giant hammer around to swap back to S3, I would prefer
that we find the problems in the kernel preventing you from getting into deep
enough C states to not burn too much battery.  

Can you please start with the following:

1) run powertop --autotune

This will reconfigure many of the defaults from the kernel to "better" values
for power management purposes.

See if that helps in a measurable way.  If it's not helping in a significant
way than this will require some more debugging.

Can you please notate if you have an NVMe SSD or SATA SSD in your XPS 9370?
