Released in September 2012, the iPhone 5 is Apple’s sixth-generation touchscreen smartphone that runs on iOS. It succeeds the iPhone 4S and precedes the iPhone 5s and iPhone 5c.
The iPhone 5 features major design changes, including an aluminum-based body (thinner and lighter than previous models), a longer screen, the Apple A6 system-on-a-chip, LTE support, and Lightning, a new compact dock connector that replaces the 30-pin design used by previous iPhone models. The iPhone 5 is the second iPhone to feature the Sony-made 8MP camera. Initial demand for the iPhone was so tremendous that it exceeded the available supply on the September 21, 2012, launch.
Over 2 million pre-orders for the phone were received within 24 hours, and in the first 16 days after the phone’s initial release, it represented over 20 percent of all phones sold in that period. In September 2013, Apple officially discontinued the iPhone 5, announcing its successor, the iPhone 5s and, later, the iPhone 5c.
