How to Save Power in Ubuntu and Make Your Battery Last Longer

People that used to use Windows before using Ubuntu may have noticed that Ubuntu consumes battery energy very fast; this is due to the fact that, unlike Windows, Ubuntu doesn’t have any energy manager installed with it. In this post, I will be showing you how to install one called Jupiter.

Jupiter is a tool that changes your laptop configuration into ones that does not consume too much energy, such turning down Wireless when you are not using it and reducing the screen brightness…

But wait a second; all these stuff can be done manually, aren’t they?

Yes of course! but Jupiter does them automatically ;)

To install Jupiter, we’ll use PPA repositories. So we need to run these commands:

sudo apt-add-repository ppa:webupd8team/jupiter

sudo apt-get update

sudo apt-get install jupiter

Jupiter is a great tool, though there is other methods to use so as to reduce energy consumption; for instance, you can log in using Unity 2D or Gnome Classic with no visual effects instead of Unity. I’ll be covering this in one of my next posts.

      The reason why find Ubuntu “so complicated” is that it is diferent than the OS you used to use. Do remember the first time you used windows ?
      Software Center is nothing but an interface that shows softwares in different locations called “PPA repositories”, by default, it shows official repositories’ softwares, yet you can add more softwares’ repositories. In this post I firstly added Jupiter repository using command-line (which can also be done through software center menus) then I installed it using the same thing, and if you don”t want to use command lines, after adding Jupiter repository, you’ll find if in the Software Center.
