When the raspberry pi 4 first came out it ran much hotter.
Raspberry pi 4 power consumption watts.

For raspberry pi 0 3 we recommend our 2 5a micro usb supply.
The power requirements of the raspberry pi increase as you make use of the various interfaces on the raspberry pi.
Pi state 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.
More performance means more power consumption.
Raspberry pi 4 b.
The official raspberry pi 4 power supply which costs around 10.
Which consumes a mere 0 8 watts at idle and 1 6 watts under load.
The biggest issue i see with this increased power consumption is the additional heat.
See this post for more information and instructions how to do all of the above.
That s considerably more than the raspberry pi 3 b s consumption with 3 1 watts ethernet and 2 5 watts wi fi.
Conserve raspberry pis power consumption.
Especially if you put this pi 4 in the official pi 4 case with zero ventilation.
For raspberry pi 4 we recommend our 3a usb c supply.
The pi 3 model b saw it s power consumption increase by 50 from compared to the pi 2 model b.
As you d expect higher power consumption will lead to much of the energy being converted to heat.
The gpio pins can draw 50ma safely distributed across all the pins.
When idle the new raspberry pi requires 4 4 watts with a usb keyboard mouse and ethernet.
