The iPhone 6 and iPhone 6 Plus[a] are smartphones that were designed and marketed by Apple Inc. They are the eighth generation of the iPhone, succeeding the iPhone 5, iPhone 5C and iPhone 5S, and were announced on September 9, 2014, and released on September 19, 2014. The iPhone 6 and iPhone 6 Plus jointly were themselves replaced as the flagship devices of the iPhone series by the iPhone 6S and iPhone 6S Plus on September 9, 2015. The iPhone 6 and 6 Plus include larger 4.7 and 5.5 inches (120 and 140 mm) displays, a faster processor, upgraded cameras, improved LTE and Wi-Fi connectivity and support for a near field communications-based mobile payments offering.
The design of the iPhone 6 and iPhone 6 Plus is influenced by that of the iPad Air with a glass front that is curved around the edges of the display, and an aluminum rear that contains two plastic strips for the antenna. The back is built of 6000-series aluminum. Both models come in gold, silver, and "space gray" finishes. The iPhone 6 has a thickness of 6.9 millimetres (0.27 in), while the iPhone 6 Plus is 7.1 mm (0.28 in) in thickness; both are thinner than the iPhone 5c and iPhone 5s, with the iPhone 6 being Apple's thinnest phone to date.
