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]

model name      : 13th Gen Intel(R) Core(TM) i7-13700H

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:
https://marc.merlins.org/tmp/merlin-sleep-6.14.5_dmesg.txt
https://marc.merlins.org/tmp/merlin-sleep-6.14.5_acpi.txt

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
rmmod ieee80211
rmmod ieee80211_crypt_wep 2>/dev/null
rmmod ieee80211_crypt_tkip 2>/dev/null
rmmod ieee80211_crypt 2>/dev/null
rmmod mac80211 2>/dev/null
rmmod cfg80211 2>/dev/null

This bit of dmesg just before sleep may be relevant:
