The iPad 4 with Retina Display from Apple features an incredibly thin design and even more power than its predecessors. The improved Retina display contains 4 times more pixels than the iPad 2 for outstanding clarity and sharpness with both text and images. A newly designed dual-core A6X chip with quad-core graphics provides a great deal of processing power and speed to compensate for the increase in resolution and delivers the same responsive feeling of the former models. This increase in power and resolution all come without the cost of lessened battery life; the iPad still features up to 10 hours of power between charging.
