The battery info was already working for me on desktop mode. It even has a nice bubble when the battery of the controller is low.

Glad that this is coming to game mode, too.

Thanks you for the clarification!

According to Wikipedia, there are less than 5000 games for nintendo switch, while the Steam Deck is far beyond 10k games.

If you are not happy, then try a few more distros.

Back then I was on reddit every week to find out when I might be able to order the steam deck. I got mine in may or june if memory serves me right.
