Default shutdown wattage is around 1 to 1.4W. However this can be decreased by manually editing the EEPROM configuration, sudo rpi-eeprom-config -e and change the settings to:
sudo rpi-eeprom-config -e
BOOT_UART=1 POWER_OFF_ON_HALT=1 BOOT_ORDER=0xf416
To cancel a pending update run "sudo rpi-eeprom-update -r".
