The iPhone 6 and iPhone 6 Plus are smartphones designed and marketed by Apple Inc. The devices are part of the iPhone series and were announced on September 9, 2014, and released on September 19, 2014.[16] The iPhone 6 and iPhone 6 Plus jointly serve as successors to the iPhone 5c and iPhone 5s.
The iPhone 6 and iPhone 6 Plus include a number of changes over their predecessor, including models with 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 iPhone 6 and 6 Plus received positive reviews, with critics regarding their improved design, specifications, camera, and battery life as being improvements over previous iPhone models. However, aspects of the design of iPhone 6 were also panned, including plastic strips on the rear of the device for its antenna that disrupted the otherwise metal exterior, and the screen resolution of the standard-sized iPhone 6 being lower than other devices in its class. Pre-orders of the iPhone 6 and iPhone 6 Plus exceeded four million within its first 24 hours of availability—an Apple record.[19] More than ten million iPhone 6 and iPhone 6 Plus devices were sold in the first three days, another Apple record.[20]
Despite their positive reception, the iPhone 6 and 6 Plus have been the subject of several hardware issues, including most prominently, being susceptible to bending under pressure (a design flaw nicknamed "Bendgate"), and as a byproduct of this lack of rigidity, the touchscreen's hardware being susceptible to losing its connection to the phone's logic board (nicknamed the "touch disease"). The iPhone 6 Plus was also the subject of camera issues, including some devices with malfunctioning optical image stabilization or otherwise faulty rear cameras.
