Experience
Battery Widget for Awesome WM
https://github.com/lexa/awesome_upower_batteryDisclaimer: The project was implemented by me in my free time for fun.
An UPower-based battery widget for Awesome WM.
This is a text widget for displaying battery status. It is different from other existing implementations in that it uses UPower to access battery information via DBUS and works in non-blocking mode, preventing WM from stuttering.
