In theory, yes. In practice, dealing with games is not so straightforward. Even the steam deck’s “suspend” is still far behind the Nintendo switch’s. In some games (older stuff, usually) the games don’t get paused at all, or it pauses the image but keeps the sound playing, or even sometimes appears to work properly, but then drains your battery just as fast as it you were playing - suggesting it is still processing the whole game in the dark.
