It's weird to do this daily, but it's possible that the UPS is doing a self test, which would drain the battery a little and the load is from charging it back up.

Surely this wasn't the same report that failed to find any EV maker that actually uses 'dirty nickel', but concluded they were anyway.
It can, but it requires creating your own signing key, registering it with secure boot, and signing your nvidia driver.
There's a guide here: https://askubuntu.com/a/1049479
But if you're running any out of tree drivers (e.g. the nvidia driver), I'd recommend just leaving secure boot off.
I never mentioned vulnerabilities, I just wanted to point out that, RDP doesn't really work without a graphical session, Windows Server Core gets around this by being a graphical session (although very basic).
Also I'm not sure, but I don't think Windows handles RDP on the kernel level, it's just nicely tied in with DWM and doesn't have to deal with the multitude of window managers on Linux.
Handling RDP on the kernel level does sound like a bad idea security wise, but there should be a better way.
I wonder if this made it into the android kernel: https://www.androidpolice.com/pixel-stutter-bug-addressed-by-third-party-dev/
Or if it is just general updates.
Ahh sorry, I thought you meant you plugged it into the input side. If that's the case then are you running anything that measures CPU usage? I run the TIG stack, it might be able to give you some hits. Also back to my original point which is already unlikely, if it's a modified sinewave UPS, it can confuse some measuring devices while it's on battery.
