I hope this guide has helped in terms of saving power on the Linux desktop as canary can quiet visibly make a noticeable difference on power usage in long sessions. The first setup is librewolf empty + discord canary, the second is librewolf empty + discord main, and the third is librewolf with discord web app.

I ran 3x each setup testing them for 240 seconds each time to give it time to equalize out and then averaged out the result. I decided to for each of the setups test it 3 times using powertop to test it. And optimizations are the ones done by powertop auto tune. The modules that are installed are 2 USB-C, 1 USB type A and 1 DisplayPort. I am using Librewolf as my browser and have installed discord and discord canary from there arch package and AUR package respectively. Mostly I wanted to test between the main discord app, the discord canary app(which uses a newer version of electron) and the discord web browser version as I found that the default discord app doesn’t let the cpu enter lower c-states. Hey everybody, today I decided to do some testing of power levels for discord on Linux desktop.
