Optimise Battery Life

We recommend using a combination of TLP and PowerTop to optimise battery life.

Configuring via PPA

You can easily install and configure our recommended battery tweaks via our PPA by opening a terminal window from the Gnome Launcher and entering the below commands:

sudo add-apt-repository ppa:starlabs/ppa
sudo apt update
sudo apt install starlabs-power

Manual Configuration

 If you would like more control over this process, below are the individual steps to setup these tweaks.

Install tlp and powertop:

sudo apt install tlp powertop -y

Configure powertop with the below command, this usually takes around 15 minutes to run and you will not be able to use your computer whilst it is running:

sudo powertop -c

Set powertop to start automatically every time you turn on your laptop:

sudo sed -i -e '$i \sudo powertop -auto-tune\n' /etc/rc.local

 Power Usage

After you have completed the steps above, you can use powertop to see your energy consumption by entering the below command:

sudo powertop

The most important information is in the top left, the consumption displayed in watts.

You can work out your battery life from here:

8 watts energy consumption
36 watt hour battery
36 ÷ 8 = 4.5 hours battery life
