By adding a small percentage level icon in Gnome panel, you can see how much battery left at any moment. And this tutorial will also work on Ubuntu, Debian, Manjaro, and other Linux with GNOME Desktop.
Option 1.) Single Command to show Battery Percentage in GNOME Panel:
For those familiar with Linux commands, simply open terminal from system app launcher. When terminal opens, paste the command below and hit run:
gsettings set org.gnome.desktop.interface show-battery-percentage true
To hide it again, reset the key via gsettings command:
gsettings reset org.gnome.desktop.interface show-battery-percentage
Option 2.) Toggle Battery Percentage via Gnome Tweaks:
The Gnome Tweaks configuration tool has the option to enable / disable this feature.
Firstly, search for and install “Gnome Tweaks” in Software if you don’t have it. Or run command in terminal to install the tool:
sudo dnf install gnome-tweaks
The install command varies on different Linux Distro. For Ubuntu / Debian, run:
sudo apt install gnome-tweaksAnd in Arch or Manjaro Linux, run this command instead:
sudo pacman -S gnome-tweaks
Secondly, launch Gnome Tweaks and go to “Top Bar” settings in left pane. Then you’ll see the toggle icon for ‘Battery Percentage’.
That’s it. Enjoy!
