This video shows power usage for the Raspberry Pi Pico compared to the Raspberry Pi Pico W. It compares the current used when running a simple blink micropython script on the Pico and Pico W. I then created a web server and compared that.
I've also compared the Pico W against some simple electronics and the much higher requirements of the Raspberry Pi Zero 2W.
