The iPhone 5S is a smartphone developed by Apple Inc. The phone maintains a very similar design to its predecessor, aside from the introduction of a new home button design using a laser-cut sapphire cover surrounded by a metallic ring, Touch ID, a fingerprint recognition system built directly into the home button which can be used to unlock the phone and authenticate App Store and iTunes Store purchases, and an updated camera with a larger aperture and a dual-LED flash optimized for different color temperatures.
iPhone 5S is powered by the Apple A7 system-on-chip, which the company proclaimed to be the first 64-bit processor ever used on a smartphone. The device's operating system and pre-loaded software were optimized to run in 64-bit mode, promising increased performance; third-party app developers would need to optimize their apps to take advantage of these enhanced capabilities.
