Despite the relatively beefy specs of the Nintendo Switch 2, the battery life will still be comparable to the original launch Nintendo Switch while undocked. The exact battery life will depend on several factors, like brightness settings, the game being played, and several other hardware settings, but with a slightly larger battery than the original Switch, players can expect a life expectancy roughly in-line with that of the launch version of the original console. With the Switch 2 being much stronger, that could be a good sign for handheld players.
