Was wondering which was best to recharge your DS. If you leave it plugged in, just while you're playing, or all the time. Or if you leave the charger plugged in, and just attach it to the DS when it needs to be charged, or you play it. Would it harm it? I know it sounds weird, but I'm just afraid to damage it in any way, even just the battery, and I have no clue what my mom did with the instructions when she cleaned out my room.
