View Battery Usage on Your Ubuntu Laptop with CPU-G

Monitoring battery life of your Ubuntu laptop just got a touch easier.

The Atareao team has added a new battery usage and information section to its fork of the CPU-G hardware information tool (think CPU-Z on Windows).

You’re probably familiar with seeing a timeline power usage graph on your mobile device, be it Android, Ubuntu or iOS.

The latest update to CPU-G brings this feature to the Ubuntu desktop.

When enabled, CPU-G runs a cron process every 5 minutes. This process logs the battery state.

Using the information it gather CPU-G is then able to display you a graph showing you how fast your battery has been depleted (hopefully not any faster once this cron job is running, eh?) — and estimate how much longer it’s likely to last!

Along with details on battery capacity the new battery section shows other power-related stats, including battery  manufacturer, model, reference number, etc.

CPU-G can show a heap more information besides, but this post is simply highlighting its battery update.

Install CPU-G on Ubuntu 16.04 LTS

To install CPU-G on Ubuntu 16.04 you can run the following commands in a new Terminal Ctrl + Alt + Twindow:

sudo add-apt-repository ppa:atareao/atareao

Alternatively, you can download an installer package directly from the PPA’s packages page:
