You cannot sudo echo to a file. The opener of the file is still regular-
user.
Try either:
sudo sh -c 'echo deep > /sys/power/mem_sleep'
Or:
echo deep | sudo tee /sys/power/mem_sleep >/dev/null
(P.S. Looks like I'm affected too with XPS13 on Focal. Draining at 0.3W in
s2idle. This did not appear to be an issue with Bionic.)
