The iPhone 5S( marketed with a stylized lowercase's' as iPhone 5s) is a smartphone designed and marketed by Apple Inc. Part of the iPhone series, the device was unveiled on September 10, 2013 at Apple's Cupertino headquarters. It was released on September 20, 2013 along with its mid-range counterpart, the iPhone 5C.[11]
The iPhone 5S maintains almost the same design to its predecessor, the iPhone 5. A redesigned home button with Touch ID, a fingerprint recognition system which can be used to unlock the phone and authenticate App Store and iTunes Store purchases, has been introduced. The camera has been updated with a larger aperture and a dual-LED flash optimized for different color temperatures. It also introduced the A7 dual-core processor, which the company proclaimed to be the first 64-bit processor to be used on a smartphone, accompanied by the M7 motion co-processor. Unlike previous models, the iPhone 5S shipped in a white/gold colour scheme in addition to white/silver and gray/black.
The iPhone 5S was the first Apple device to ship with iOS 7, which introduced a revamped visual appearance and other new features. Designed by Jonathan Ive, iOS 7 departs from skeuomorphic elements used by previous versions of iOS in favor of a flat, colorful design. Among new software features introduced to the iPhone 5S include AirDrop, an ad-hoc Wi-Fi sharing platform, Control Center, a control panel containing a number of commonly-used functions, and iTunes Radio, an internet radio service. Earphones known as EarPods are included with the iPhone 5S. Apple has released accessories including a case and a dock for the iPhone 5S.
Reception towards the device was generally positive, with some outlets considering it to be best smartphone available on the market due to its upgraded hardware, Touch ID, and other changes introduced by iOS 7.[12] However, others criticized the iPhone 5S for being too similar to its predecessors, [13] while others expressed security concerns about the Touch ID system.[14][15] Nine million units of the iPhone 5S and iPhone 5C were sold on their weekend of release, breaking Apple's sales record for iPhones.[16] The iPhone 5S was the best selling phone on all major U.S. carriers in September 2013.[17]
