That is very impressive! And thank you very much for those tips. Oh, and mine tends to sit around 2.3W... and that is with over_voltage at 5, and both min and max cpu values at 1500 while running a couple things 24/7 (docker, a live stream on ffplay, pihole.)

This thread has some interesting details as well: https://forums.raspberrypi.com/viewtopic.php?t=257144
There people managed to get idle power on a Raspberry Pi 4B to a little under 1.8 W. Interestingly, people there report that on their Pi 4's disabling USB doesn't do much. If I remember correctly, there were a few Pi 4 firmware updates that optimized power consumption over time. So the different firmware versions can behave differently when it comes to power consumption.

Your 2.3 W doesn't sound too bad to begin with. Certainly better than the 5 W mentioned in the article.
