That's quite likely because the NVMe patches in #7 gets included.

What's the power consumption estimated by powertop?

Can you please test without your adapter plugged in prior to the sleep
cycle? Due to the way suspend to idle works this may cause the PCH to
remain in a higher power state burning a lot more battery.

1) When I'm on battery, there is just an USB-C adapter with just a nano
receiver for my cordless mouse. On AC, there is a USB-C all-in-one which is
plugged in (output DVI, another nano USB receiver, ethernet)
2)
$ sudo powertop with --auto-tune

> 4) Policy wise isn't TLP or something similar going to be needed to
enact RTD3 for the rest of the devices that kernel policy isn't properly
S2idle still calls all devices' suspend() callback, hence all PCIe
devices will be put to D3.
It's a known issue that NVMe needs to stays at D0

This is changing how the system goes to sleep in a significant way.
With this, the BIOS turns off all devices except RAM when going to
sleep. With the way that it works
This is weird. The patch in [1] should help a lot, it'll let s2idle
decrease its power usage significantly, not as good as deep though.
Still surprising that the battery discharge that quick. May need some
help from Dell though...

Yes, I've tested a few days ago and I believe the same behavior appears
: no really sleep mode, battery in discharge. Just the screen black.
But I've non tested with
$ sudo sh -c 'echo mem > /sys/power/state'
$ sudo sh -c 'echo deep > /sys/power/mem_sleep'
I don't know the default value of this
Does that also happen to the test kernel I built?

I will do some other tests next days but if a suspend my laptop at 1:00
with a battery loaded about 40%, when I try to resume at 7:00, the
laptop refuse to resume (battery empty). I have to plug in the charger
in order to resume

Do you mean a fully charged battery only lasts 4 ~ 6 hours?

Yes, this is right. The default on keyboard wakeup changes.
