The energy consumption should lower, so the fan does not spin.
It’d be useful to better analyze WebRTC (what video codec is used), and analyze the energy consumption in detail.

Hi,
I will move this enhancement over to a component so developers can take a look over it. If this is not the correct component please feel free to change it to an appropriate one.
Thanks for your report.
