I'd like to increase the battery life on my XPS 13 running Ubuntu 14.04. Is this possible? It seems like running a native OS like Windows performs better and would like to maximize the efficiency of the machine.
There is a package called
laptop-mode-tools, which allows extending the life of battery. Another one is
pm-utils package. You can get either with
sudo apt-get install laptop-mode-tools
sudo apt-get install pm-utils
pm-powersave is mostly command line, have to be enabled with
sudo pm-powersave true.
laptop-mode-tools has a graphical front-end to it, written in PyQT.
