Debian – Laptop Power Calibration

Since 2 years I have a Wortmann Ultrabook running on Debian. Since some weeks the the battery life has deteriorated sharply. I found this helpful article about the linux tool ‘powertop’.  You can use this tool to recalibrate the battery of a loptop using the following command:

sudo powertop --calibrate

At a first look it seems like this helped much to improve the power management of my laptop.
