Slimbook Battery offers three operating modes: "energy savings","balanced" Y "maximum performance«. All of them can be customized looking to optimize battery life even more. An option is also available in the menu that says'off'. With it you can disable optimization.

Power Options in Slimbook Battery 3

The first three buttons are the ones that can be used to switch between the different energy saving modes (Energy saving, balanced and maximum performance):

  • When any of the modes is selected the manager will ask us for the corresponding password. If it is not entered, it will not be possible to change the mode.
  • The bar indicator icon will change color to the one corresponding to the active mode: green (Energy saving), blue (Balanced) and orange (Maximum performance). We will know that the application is not using any mode because this icon will be gray.
  • The fourth button (off) will allow us disable power saving currently being used. The bar indicator icon will turn gray. When deactivated, the notebook will return to normal resources and will have normal power consumption.

To begin we will have to open the terminal (Ctrl + Alt + T). When it opens, you just have to type the following command to add the PPA:

add official power manager PPA

sudo add-apt-repository ppa:slimbook/slimbook

After adding it we can update apt cache, if it does not do it automatically, e install the tool typing in the same terminal:

At the moment I am testing it on my laptop and the battery seems to last about 20 minutes longer as I write this article, but I suppose each user should test it on their computer. It can get more information about its use and characteristics in the project website.

    It's great. I have a HP envy 13 ″ i5, 8 GB RAM, now I have it with Linux Mint 19.1. I put this manager and if it seems to me that the battery has improved. At this moment I have 3 hrs 30 minutes and it tells me that I have 2 hrs 18 minutes of battery life, I feel that it is lasting longer than normal. I put it in mode to consume less battery. I see it pretty good so far. Greetings
