Joystiq reports Nintendo's 3DS handheld console will have a significantly reduced battery life. While the DSi XL claims a battery life of up to 17 hours, the 3DS promises only 3-5 hours when playing 3D games and 5-8 hours when running regular DS games.
That's not the case with the 3DS. Nintendo revealed the final hardware specs at its Nintendo World 2011 event, announcing that the 3DS will run for 3-5 hours when playing 3DS software, and 5-8 hours when running DS games. We guess it does take a lot of power to run three displays (if you count the dual rendering required for 3D as two displays) and maintain a wireless connection. This is precisely why the device ships with that charging dock -- which, by the way, will charge the battery in about 3 and a half hours.
