24-Hour Raspberry Pi 3 Power Consumption Test: OSMC Media Center, Kodi, jDownloader & DHT11 Sensor

I decided to check how much RPi3 needs energy.
The measurement lasted 24 hours. Most of the time the computer operated more or less like this:

Quote:

load average: 0.12, 0.08, 0.09

under the control of OSMC Media Center with Kodi running.
In addition, jDownloader was launched in Java in headless mode.
A USB flash drive is connected to Raspberry. For GPIO, DHT11 sensor powered from 3.3V line.
Score:

This means that the monthly cost of electricity is about PLN 1. I assumed 0.6 PLN / kWh and 70% efficiency of the 230/5 V power supply.
(7200 mAh * 5 V) / 70% = 50 Wh (per day).
50 Wh * 30 days = 1.5 kWh.

I invite you to share your measurements.

In the absence of interest, I close the topic.
