iPad Air 2 is the thinnest and lightest iPad ever at just 6.1mm thin and 0.96 pounds. It has a more powerful A8X chip that provides 40% faster performance yet still maintains 10 hours of battery life. The display is thinner and provides more vivid colors due to redesigning the Retina display into a single laminated layer. Touch ID has also been added for secure purchases and unlocking the iPad Air 2 with just a fingerprint.
