My laptop is slow and unresponsive when running in battery; it works fawless when connected to ac power. In the past I used to have tlp/laptopmode-tools but since Linux 3.x I have uninstalled both.
Battery last long but usability is poor.
This is happening on a dell xps 13 with ivybridge CPU and Archlinux x64 with either stock kernel or ck kernel, gnome shell.



Is there anything I can tweak in order to get better performance/responsiveness on battery (I'm willing to loose some battery life).

          You might want to have a look in energy-saving mode, as it can affect your performance while running on battery.



          Unfortunately i can't give you an exact place to have a look, but from my experience i know that some ridiculous settings could be found on laptops with Windows.



          For example: your system might have set-up a time that it turns off your hard drive to save energy and each time you change a folder it has to start spinning again, what causes a lag. This is of course only if you have a HDD hard drive.
