Launched at the end of february 2017 the pi zero w has all the functionality of the original pi zero but comes with added connectivity consisting of.
Raspberry pi zero w power consumption mah.

Why don t you try using a sleepy pi 2 to optimise your battery life and get the longest runtime you can.
The power requirements of the raspberry pi increase as you make use of the various interfaces on the raspberry pi.
For raspberry pi 0 3 we recommend our 2 5a micro usb supply.
Bluetooth low energy ble like the pi zero it also has.
For raspberry pi 4 we recommend our 3a usb c supply.
The raspberry pi zero uses about the same amount of power as the a and at least 50 less power than any other pi b 2 b 3 b.
The raspberry pi zero w extends the pi zero family.
The recommended amount is between 700ma for a raspberry pi model a and up to 2 5a for a raspberry pi 3 model b see power supply requirements in the magpi issue 56 page 39.
Watts voltage x current so in raw terms the pi zero w at idle will use 0 6w however that ignores any power loss in the psu converting from mains electricity to the 5v needed by the pi zero w.
Assuming 80 efficiency that s still only 0 75 watts which works out as 6 5kwh for a whole year which would cost you roughly 80pence for a whole year in the uk.
The gpio pins can draw 50ma safely distributed across all the pins.
