In TFA they are quoting a whopping 3W on idle for the RPi5 (just search for "idle power"). I have a Celeron system that idles _measured at the wall_ at 1.8W, including 8GB of LPDDR3 and a 4TB SATA SSD. Since I measure at the wall, I'm including transformer losses, which is not usually the case if you just measure current at the USB level as you seem to be doing.
They are also saying that the RPi5 in the default power off state (which is not even a real power off) it stays at 2W.
This matches my own results from the RPi4, where I had difficulty getting it to idle at less than 3W at the wall. While my x86 result is _out of the box_ with an standard openSUSE install.
The (desktop) RPi devices are just TERRIBLE. Cheap, small, have multiple GPIOs, but terrible power-wise. The µc RPis are another story.
What are the keywords to search for to find these Celerons? I assume they're ye'olde business pseudo-light terminals? Laptops are not bad, but desktop machines have easier connectivity.
I might just buy one now because I find your wall-power results extremely surprising. My results with basically any mini-PC have been similar between Linux and Windows at minimum idle power; the Windows installs jump up off idle more often but I haven't seen a significant difference in the troughs. The Energy* and other reviews of PN40 indicate ~5W idle, which is more in line with NUCs and everything else I've ever seen from a mini-PC.
The difference between Linux and Windows is almost night and day. On my monster workstation, for example, I have managed to idle it down to 16W (or around 24W with a dGPU. it has alder lake, 6 SSDs in softraid and 128GB of RAM). I never managed to do anything less than 40W in Windows.

Even on this very thread you have been quoted lower numbers. Just search around.
