Want to increase the battery life of your Ubuntu laptop? In addition to dealing with various settings or configuration files, try the TLP power management tool and Slimbook Battery.

TLP is a multifunctional command-line utility for Linux that allows you to save laptop battery power without having to go into technical details.

The default TLP settings are already optimized for battery life and implement Powertop recommendations out of the box. So you can just install and forget about it.

How to install TLP in Ubuntu 20.04

Just open the terminal from the application menu, or press Ctrl + Alt + T on the keyboard. When the terminal opens, enter the following command:

sudo apt install tlp

After installation, everything is ready, because this utility runs in the background with the default configuration, already optimized for battery operation.

To meet your specific requirements, you can install the GTK TLPUI user interface using the following PPA repository.

Install Slimbook Battery

Slimbook Battery is a graphical tool based on TLP, it offers an indicator menu that includes three modes: Energy Saving, Balanced and Maximum Performance.
