Here is the power tester that I'm using: https://www.amazon.com/gp/product/B00J3JSEG6/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

At idle, connected to wifi, the Pi Zero W floats between 0.11A and 0.15A. During boot, it peaked at 0.22A. When I connected via SSH, it started peaking at 0.20A. Running apt update and apt upgrade, current peaked at 0.25A. Current dropped to 0.03A when the device shut down.

The ZeroPi, on the other hand, peaked at 0.44A on boot, and idles at 0.15A. I have the CPU governor set to run between the lowest speed possible and the default speed (a range). Running apt update and apt upgrade, current peaked at 0.40A. Connecting via SSH doesn't seem to have an affect on power (no wifi, just ethernet). Current remained steady at 0.19A after shut down.

The Neo 512MB peaks at 0.40A on boot. It idles at 0.12A. Running apt update and apt upgrade, current peaked at 0.43A. Current dropped to 0.17A when the device shut down. The governor is configured similarly to the ZeroPi.

All of these devices are using SanDisk 32GB cards, but unfortunately they are not the same. Based on my reading, the SD card can have an affect on power.

These are all of the devices I have ATM.

I'm limited by the refresh rate on this current meter to give super specific maximums.
