The iPad 3's battery life might not seem impressive at first, but it's a really significant improvement for Apple.

This may seem like a step backwards, but Apple managed to increase the iPad 3's battery to 11,666mAh, compared to the iPad 2’s 6994mAH.
The iPad 3 features four times as many pixels, 4G LTE and more power hungry features than the iPad 2.

The iPad 3 may not feature 3D feel displays or other gimmicky features like Siri, but its new battery capacity proves that Apple is working hard to improve their devices.
