Nintendo clocks Wii U controller life in at three to five hours on a charge

Nintendo wasn't particularly forthcoming with the specs at its keynote earlier today -- and, well, some things are probably best not mentioned when attempting to hype up your new console. Like, say, the three to five hour battery life on the Wii U GamePad. That's the word coming from a spec sheet posted by the gaming giant. Of course, that usage depends on factors like the brightness of the screen, and Nintendo warns that things may end up being shorter in the end. The slightly better news here is that you can plug the controller in to charge while playing, so that's something, right?
