That's not very idle! :-)

My pi 4 reports over 99% idle when it's doing nothing.  It moves
randomly around a bit but always stays > 99%.  What's at the top of
'top' when you run it?  On mine it's mostly 'top' at the top. (Hmm,
topping isn't it!)

My pi 4 is running headless, the only thing I've added that does use
a little CPU is syncthing keeping it synchronised with some other
machines on my LAN.
