스택오버플로우에 테스트를 통해 소비전력을 비교한 좋은 글이 있다. (전체 RPi, RPi Zero W)
물론 정확하진 않지만 참고할만은 하다.
아래는 링크를 정리한 글이다.
B with keyboard = 1.89 W -> daily 45 Wh [6] B+ with keyboard = 1.21 W -> daily 29 Wh B+ with LAN/USB chip off (no i/o except GPIO) = 0.76 W -> daily 18.2 Wh B+ shut down = 0.26 W -> daily 6.2 Wh A idle = 0.7 W -> daily 17 Wh A+ idle = 0.52 W -> daily 12.5 Wh Pi2 B at idle = 1.15 W -> daily 28 Wh Pi3 B at idle = 1.15 W -> daily 28 Wh Pi3 B at 100% * 4 CPUs = 3.6 W -> daily 86 Wh Pi Zero at idle = 0.51 W -> daily 12.2 Wh Pi Zero W at idle = 0.5 W -> daily 12 Wh Pi Zero W Bluetooth turned on = 0.8 W -> daily 19.2 Wh Pi Zero W WiFi turned on = 0.85 W -> daily 20.4 Wh Pi Zero W with Camera Capturing = 1.15 W -> daily 27.6 Wh
