[TriEmbed] Raspberry Pi idle current vs clock rate(s)

[Trampas Stern]

There are other chips consuming power beyond the processor:

LAN
WIFI
HDMI
etc

Typically power increases exponentially with clock rate.  However I bet the
OS internally is sleeping the processor when idle, effectively dropping
clock rate. I doubt your power will drop significantly by underclocking at
idle unless you disable other chips and peripherals.

This most likely does not solve your problem but might answer
your question.
