Nintendo 3DS’ battery life seems to be suspect, compared to its predecessors that is. The official numbers are three to five hours playing per game for 3D games, or five to eight if playing an older DS title(with up to three hours 30 minutes to fully recharge)…..

Now The DS is 10 to 14 hours, DS Lite 15 to 19 hours, DSi 9 to 14 hours, and DSi XL 13 to 17 hours. I tell you what for Nintendo and our sanity(knowing we spent so much on said device) the 3DS better blow us away on gaming, to the point where we only want to play it for 3 to 5 hours then need at least 3 1/2 away from it, then everything will be just fine 🙁
