The iPhone 5s was released in 2013 as a successor to the iPhone 5. While previous “s” updates delivered only slight enhancements, the 5s had major upgrades internally and externally. The iPhone 5s included an A7 chip (Apple’s first 64-bit “system-on-a-chip”), Apple’s first fingerprint Touch ID, and greatly enhanced cameras with a flash system that used different color temperatures.
The iPhone 5s was offered in three metallic colors: silver (white glass front with a metallic sliver back), gold (white glass front with a metallic gold back), and space gray (black glass front with metallic gunmetal gray back). Its touch screen was a Retina display (1136 x 640). The back camera was an 8-megapixel iSight camera (1080p), and the front camera was a 1.2 megapixel FaceTime camera (720p).
The A7 chip that powered the iPhone 5s ran at 1.3 GHz and storage was offered at 16, 32, or 64 GB. Wireless connections included 802.11n Wi-Fi, Bluetooth 4.0, and 4G/LTE. Wired connections included the Lightning connector and a standard headphone jack.
This was the first iPhone to ship with iOS 7, the first iOS version designed under Jony Ive that removed the previous “skeuomorphic” design aesthetic that used true-life design elements such as faux textures, drop shadows, glossy surfaces, beveled edges, and other real-world visual cues (e.g., the Notes app icon resembled a legal pad with torn-off pages, the Newsstand app icon that resembled a book case). Instead, iOS 7 icons and interfaces were flat and featured a defined colorful palette.
