Power consumption of the Raspberry Zero W

Here's my test results from the current consumption of the Raspberry Zero W

• WiFi connected and cpu IDLE: 0,7 W
• Wi-Fi network and CPU load: 1,2 W
• WiFi connected, HDMI out, cpu IDLE: 0,6 W
  /usr/bin/tvservice -o
• WiFi connected, HDMI out, cpu load: 1,1 W

Since I do not need HDMI, I switch it permanently off in the /etc/local.rc

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi
