Nintendo's bigger Wii U GamePad battery seems to bring a far bigger amount of juice for gamers hungry for extended wireless action.
Despite being fully operational when tethered to a charging station, there have been many complaints from Wii U owners that the default battery, which is removable, doesn't last very long whilst playing. The newer battery pack, which now sits horizontally instead of vertically, offers 2550mAh of juice - far more than the default 1500mAh. The original ran between 3-5 hours, with the newer capacity extending that figure to between 5-8 hours.
Japanese website Game Watch tried out the new battery, with highest brightness, power-saving disabled and the Monster Hunter 3 Ultimate movie playing over, and over. The time before the controller powered-down was 5 hours and twelve minutes, compared to 3 hours.
No additional/larger back cover seems to be required (as with some battery backs), as the battery just about fits within the extra space inside the controller itself.
Would you upgrade your Wii U battery for extra play time?
