It’s become traditional for me to do power measurements of any new Pi and update my chart. People have even started asking me about it on launch days (the cheek of it)…
@DavidGlaude No. Not yet. Patience. That’s usually a day 2 thing 🙂

Needless to say I have done some power measurements in my Zero W testing and here are the results. Essentially, the Pi Zero W seems to require 20 mA more than the no-wifi Zero. This is almost certainly due to the new radio chip.
Measurements were taken using my standard procedure (same as for the last several Pi models launched). Current and voltage are measured using my eMeter with a calibrated 20 Amp shunt whilst performing four different activities. “Shooting video” is done without saving the video output to the SD card. Watching video is done with a 1080p video on the SD card. The rest is self-explanatory. The camera module is unplugged for all but the shooting video test. Only HDMI and a USB keyboard dongle were plugged in. The Pi Zero W was connected to wifi, but no bluetooth devices were in use.
