iPhone 6/6 Plus

The iPhone 6 and iPhone 6 Plus are smartphones designed and marketed by Apple Inc. It is the eighth generation of the iPhone, succeeding the iPhone 5S, and was announced on September 9, 2014 and released on September 19, 2014.[18] 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 paymentsoffering.[19][20]

The iPhone 6 and 6 Plus received positive reviews, with critics regarding their redesign, 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.[21] More than ten million iPhone 6 and iPhone 6 Plus devices were sold in the first three days, another Apple record.[22] During its lifespan, the iPhone 6 and 6 Plus sold 220 million in total, making them the best selling iPhone models, so far, and one of the most successful phones to date.

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 hard pressure (dubbed "Bendgate"), and as a byproduct of this lack of rigidity, the touchscreen's internal hardware being susceptible to losing its connection to the phone's logic board (nicknamed "Touch Disease"). Additionally, some iPhone 6 Plus models were the subject of camera issues, including some with malfunctioning optical image stabilization or otherwise defects on rear cameras.
