3DS has 3-5 hour battery life for 3DS games

One of the remaining questions about the 3DS hardware since its debut has been will it destroy your eyes how long will the batteries last? After all, DS hardware revisions have generally upped the battery capacity, even when increasing the size of the screens (the DSi XL claims up to 17 hours!)

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.
