Who'd have thought that adding extra grunt under the hood, a glasses-free 3D display up top, a wireless "tag mode," and automatic wireless updates to the 3DS would serve to degrade battery life? Certainly not our naive souls. The same Q&A that informed us about Nintendo's Spot Pass plans for the 3DS has been found to also contain some commentary on battery endurance from Satoru Iwata himself. The company chief says "it is inevitable that Nintendo 3DS will be a device which requires more frequent recharging than Nintendo DS" and notes that as a major reason why a charging cradle will be bundled into the new console's retail package. With tongue firmly wedged in cheek, Iwata suggests that perhaps Nintendo ought to advise users to deposit the 3DS into its cradle as soon as they get home, but the overall point is as clear as it is obvious: your more powerful handheld will require more power.
