TLP - Optimize Linux Laptop Battery Life

 The latest i added to my Ubuntu laptop is TLP.

TLP is a feature-rich command line utility for Linux, saving laptop battery power without the need to delve deeper into technical details,
Default settings are already optimized for battery life and implement Powertop’s recommendations out of the box, so you can install it and just sit back and relax!
And TLP is completely customizable, which means you can get even more power savings or meet your exact requirements – the possibilities are endless.

I can write a whole story, but best is to read it on the right webpage and see if it's suitable for your Distro.

Despite that i love the terminal, do i also like a GUI.
There is a GUI for TLP but you need Python to run it.
