Fair point, I somehow failed to upgrade the kernel on that machine.
I have a 6.14.5 kernel I just installed.
I also upgraded all firmware:
dpkggrep firmware | awk '{ print $1 }' | xargs apt-get install -t unstable -y

My thinkpad has:
sauron:~# cat /sys/power/mem_sleep
s2idle [deep]
The Dell XPS only has:
merlin:/usr/src# cat /sys/power/mem_sleep
[s2idle]

Ok, I tested again with the new kernel. The laptop didn't feel warm when
in sleep, but I lost 20% battery in 4H, which means the battery would
not last 24H in sleep
For logs, which one did you want? I have pretty full logs here:

One thing I changed recently is that unloading wireless altogether,
causes issues at times, so now I have
rfkill block wlan
instead of
killall wpa_supplicant &>/dev/null
pkill -f "dhclient.*wlan0"
ifconfig -a | grep -q wlan0 && ifconfig wlan0 down
rmmod iwlmvm
rmmod iwlwifi iwlagn iwlcore

This bit of dmesg just before sleep may be relevant:
