iPhone 6 and iPhone 6 Plus

The iPhone 6 and iPhone 6 Plus are iOS smartphones designed and manufactured by Apple Inc. The phones were unveiled during Apple Live on September 9, 2014, alongside the Apple Watch. The iPhone 6 serves as a successor to the iPhone 5S. The models mark the first major increases in physical screen size for the iPhone line since the taller screen of the iPhone 5, measuring at 4.7 inches (120 mm) and 5.5 inches (140 mm) for the Plus version.

Many rumors surrounding the next iPhone centered around the device's size; the majority of iPhone models have used small, 3.5-inch displays—which are relatively smaller than the larger screens used by flagship phones from competitors. The only major change in size for the iPhone line came with the iPhone 5, which featured a new display that was taller, but the same width as prior models, measuring 4 inches diagonally. As the result of Apple's loss in smartphone market share to companies producing phones with larger displays (such as Samsung, whose popular Galaxy S4 model featured a 5-inch screen),^[6] reports as early as January 2014 suggested that Apple was preparing to launch new iPhone models with larger, 4.7-inch and 5.5-inch displays.^[6][7][8] Reports prior to its unveiling also speculated the possibility that Apple would use a new iPhone model to introduce a mobile payments platform using near-field communications—a technology that has been incorporated into many Android phones, but has a low adoption rate among users.^[9]

The iPhone 6, along with the iPhone 6 Plus phablet, were officially unveiled during a press event at the Flint Center for Performing Arts in Cupertino, California on September 9, 2014. The event featured other major product announcements by Apple alongside the new iPhone models, including the Apple Pay mobile payment platform, and the company's entry into the wearable computing market with the Apple Watch smartwatch.^[10]

The iPhone 6 line will be released on September 19, 2014, with pre-orders beginning on September 12, 2014.^[11] In China, where the iPhone 5S and 5C were the first models in the iPhone series to be released in the country on the same day as their international launch, Apple notified local wireless carriers that it would be unable to release the iPhone 6 line in China on the 19th because there were "details which are not ready"; local media reported that the devices had not yet been approved by theMinistry of Industry and Information Technology, and earlier in the year, a news report by state broadcaster China Central Television alleged that iPhone devices were a threat to national security because iOS 7's "frequent locations" function could expose "state secrets
