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.)
