I’ve been considering getting a mini PC for my living room, basically only to watch online videos without ads or watch locally stored videos.

Since I have a Steam deck available that I already often dock to my screen for gaming, could I use it instead of buying a new computer?

My main concern is the impact this would have on the battery if it’s plugged in for long periods of time, does it bypass the battery when it’s plugged in and the battery is full ? Will other components be impacted?
