There are other chips consuming power beyond the processor: https://forums.raspberrypi.com/viewtopic.php?t=152692
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.
