<div style="font-family:monospace"> <span dir="ltr" style="margin-top:0px;margin-bottom:0px">Can anybody speak to this? I'm told (by an eager word-guesser aka "ai") that a Pi 4 idles around 575mA. If I drop the clock from 1200 to 600mHz (as low as it will go if my other info is right) I wonder if this will cut the idle current in half or is it likely to be a larger fraction?</span>
