I haven't got hard data but I don't perceive any difference with this update.

- could you please describe the process to run such measures?

Very simple; I just have a small shellscript that logs power usage, like this:
Code:
#!/bin/bash

battery=$(upower -d | grep percentage | awk '{print $2}')
date=$(TZ='Europe/Helsinki' date "+%d.%m.%Y %H:%M")
echo "$date  -->  $battery"
Then I have entry in my crontab that calls the script every half-an-hour;
Code:
# log power usage every 30 minutes
1,31 * * * * /home/nemo/bin/powerlog.sh >> /home/nemo/powerlog.txt
