The game has been set to the point just in front of the village leader after leaving the main gathering spot. The 3DS is the Zelda 25th anniversary system with the system's standard 1300mAh battery. It's playing Monster Hunter 3G and is also set to in front of the village leader spot. The Vita is the 3G/Wi-Fi model with its standard 2210mAh battery. It's playing Uncharted off a game card. All three systems are set to highest brightness and highest volume. The 3DS 3D volume is set to max. The results: 3DS dies at 2 hours 35 minutes. Vita dies at 3 hours 47 minutes. PSP dies at 9 hours. *My opinion*What a disgrace the 3DS is. Only 2hrs and 30 minutes. wow. :lol:
