iPhone 5S is a smartphone developed by Apple. It is part of the iPhone line, and was released on September 20, 2013. Apple held an event to formally introduce the phone, and its mid-range counterpart, the iPhone 5C, on September 10, 2013.
As with the principle of iPhone 3GS and iPhone 4S, iPhone 5S is a revised version of its predecessor, iPhone 5. 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 Store and iTunes Store purchases, and an updated camera with a larger aperture and a dual-LED flash optimized for different color temperatures. It also introduced the A7 dual-core processor, the first 64-bit processor to be used on a smartphone, accompanied by the M7 "motion co-processor", a dedicated processor for processing motion data from its accelerometer and gyroscopes without requiring the attention of the main processor. It was also the first Apple device to ship with the newest version of the iOS mobile operating system, iOS 7, which introduced a revamped visual appearance and other new features.
