This Indicator Shows Laptop’s Battery Health in Ubuntu 20.04, 21.10

Want to check your laptop battery status in Ubuntu or other Linux? There’s a small indicator applet that can do the job in GNOME desktop.

“Battery Status” is the free and open-source indicator applet developed by Lorenzo Carbonell, a software developer behind touchpad-indicator and my weather indicator.

It displays an icon on GNOME top bar in system tray area, along with the battery remaining time. By clicking on the applet, it shows battery percentage based on both current and original maximum capacities.

As well, it shows battery health via current and original maximum capacities, and the original and current Voltages.

A setting dialog is also available to configure the refresh time, warning, and colors, etc.

NOTE: The pre-installed Firefox in Ubuntu 21.10 is a Snap package that does NOT support for installing Gnome Extensions so far. Use another browser or install Firefox as deb.

The indicator should appear immediately after installation. If not, try to enable it via “Gnome Extensions” app, which can be installed via command:

That’s all. Enjoy!
