Watching videos on 720p instead of 1080p cuts the energy consumption of your phone in half!

I just stumbled upon this "The impact of video quality on energy efficiency and network usage for video streaming applications on Android"

According to their research the energy savings are significant!

Makes me wonder if I can somehow fix it to 720p on all me devices (especially since my phone's display does not support 1080p natively and would have to downsize the image anyway).

Also last week I stumbled upon a paper which said that only ~20% of GitHub Actions use Caching, which makes me wonder how much low hanging fruit is out there that we can use the make SW more energy efficient and performant!
