Yesterday I did a very quick test with things like:
- screen off
- turn off wifi radio
- almost all daemons (including bluetooth and network-manager) and almost no programs running.
- set cpu frequency to 1.2Ghz
My notes are on the Reform itself but I can not boot it right now, don´t remember if I did something else. It went from 57% to 34% in 1:30 hours, which would translate to 6:30 hours from 100% to 0%.
I did not shut down cpu cores, but I’ll try that too. Also, the user session resides on a cgroup2, so it could be completely frozen and resumed, but anyway I killed everything except for sway itself.
