The iPhone 6 is smartphone designed and marketed by Apple Inc. It is the eighth generation of the iPhone, succeeding the iPhone 5S that was announced on September 9, 2014, and released on September 19, 2014. 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.

Design

The design of the iPhone 6 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. Both models come in gold, silver, and "space gray" finishes. The iPhone 6 has a thickness of 6.9 millimeters (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. The most significant changes to the iPhone 6 and iPhone 6 Plus are its displays both branded as "Retina HD Display" and "ion-strengthened", the iPhone 6 display is 4.7 inches in size with a 16:9 resolution of 1334x750 (326 ppi, minus one row of pixels), while the iPhone 6 Plus includes a 5.5-inch 1920x1080 (1080p) display (401 PPI). The displays use a multiple-domain LCD panel, dubbed "dual-domain pixels" the RGB pixels themselves are skewed in pattern, so that every pixel is seen from a different angle. This technique helps improve the viewing angles of the display.

Battery

To accommodate the larger physical size of the iPhone 6, the power button was moved to the side of the phone instead of the top to improve its accessibility. The iPhone 6 features a 6.91 Wh (1810 mAh) battery, while the iPhone 6 Plus features an 11.1 Wh (2915 mAh) battery. Unlike the previous model, the rear-facing camera is not flush with the rear of the device, but instead protrudes slightly.

Chipset

Both models include an Apple A8 system-on-chip, and an M8 motion co-processor an update of the M7 chip from the iPhone 5s. The primary difference between the M8 and the original M7 coprocessor is that the M8 also includes a barometer to measure altitude changes. Phil Schiller touted that the A8 chip would provide, in comparison to the 5s, a 25% increase in CPU performance, a 50% increase in graphics performance, and less heat output.

Camera

The iPhone 6's rear-facing camera now has the ability to shoot 1080p video at either 30 or 60 frames per second and slow-motion video at either 120 or 240 frames per second. The camera also includes phase detection autofocus. It can also record.

Operating System

When first released, the iPhone 6 was supplied pre-loaded with iOS 8, while the iPhone 5S was supplied pre-loaded with iOS 7. Apps are able to take advantage of the increased screen size in the iPhone 6 to display more information on-screen; for example, the Mail app uses a dual-pane layout similar to its iPad version when the device is in landscape mode on the iPhone 6 Plus. To improve the usability of the devices' larger screens, an additional "Reachability" gesture was added; double-tapping the Home button will slide the top half of the screen's contents down to the bottom half of the screen. This function allows users to reach buttons located near the top of the screen, such as a "Back" button in the top-left corner. Upgradable to iOS 12.
