Topic: Switch charge

I just want to know when my switch is 100 percent charged and I'm still playing it in my Dock so I can play on my TV will that damage the charging system? And can you play it on your TV without it charging???

You can't have it not charge, but it is completely harmless. The Switch was designed for this. The only thing I would suggest, is like all electronics, keep is in a mild room, you don't want it sitting near a heat duct in winter, and in summer you want to avoid playing for long stretches if you aren't keeping the room cool. Even then, this is Nintendo, and they make their products durable.
