The biggest issue i see with this increased power consumption is the additional heat.
Raspberry pi 4 standby power consumption.

I m seeing power consumption a little higher than your measurements but this may depend on if you re booting to a cli or desktop and what networking you are using.
Assuming 80 efficiency that s still only 0 75 watts which works out as 6 5kwh for a whole year which would cost you roughly 80pence for a whole year in the uk.
Especially if you put this pi 4 in the official pi 4 case with zero ventilation.
Watts voltage x current so in raw terms the pi zero w at idle will use 0 6w however that ignores any power loss in the psu converting from mains electricity to the 5v needed by the pi zero w.
Replace the linear regulator with a switching regulator from our shop.
I use the powerjive usb power meter for older pis with micro usb power inputs or the satechi usb c power meter for the pi 4 and newer to measure power consumption with the dramble and individual raspberry pis in all cases with nothing plugged into usb unless otherwise noted.
We also used another regulator for the 5v power to test powering a pi from a.
Which program will work for you depends on the usb to sata controller you have and the hard drive itself.
The new raspberry pi 4 has two eeproms electrically erasable programmable read only memory that store the firmware boot loader code as well as the code of the usb 3 0 host controller vl805 in previous raspberry pi boards the firmware was stored on the sd card.
Few days ago a new firmware has been released that updates the vl805 code to the version 000137ab.
This dissipates a third of the energy as heat which is a bit of a waste if you want to power your pi from an battery.
Whether you re editing documents browsing the web with a bunch of tabs open juggling spreadsheets or drafting a presentation you ll find the experience smooth and very recognisable but on a.
The raspberry pi zero uses about the same amount of power as the a and at least 50 less power than any other pi b 2 b 3 b.
I will be adding power consumption statistics to this page as time goes on.
I have included guides for hdparm hd idle and sdparm which should cover most users wanting to manage hard drive power consumption on the raspberry pi.
Your tiny dual display desktop computer.
The speed and performance of the new raspberry pi 4 is a step up from earlier models.
The raspberry pi relies on a linear regulator for its 3v3 rail.
I recommend using hdparm or hd idle and using sdparm as a last resort.
