iPhone 6

The iPhone 6 and iPhone 6 Plus are smartphones running iOS developed by Apple Inc. The devices are part of the iPhone series
and were released on September 19, 2014. 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 its predecessor, including models with larger 4.7-inch and 5.5-inch
displays, a faster processor, upgraded cameras, improved LTE and Wi-Fi connectivity, and support for a near-field communications-based
mobile payments offering.

Pre-orders of the iPhone 6 and iPhone 6 Plus exceeded 4 million within its first 24 hours of availability—an Apple record.
More than 10 million iPhone 6 and iPhone 6 Plus devices were sold in the first three days, another Apple record.

New Features


The design of the iPhone 6 line 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.
They also used the new volume buttons used on the iPad Air, unlike the circular volume buttons with the “+” and “-” symbols used on the iPhone 4, 4S, 5, and 5S.
(The iPhone 5C used the same volume buttons as the iPad mini.)[29] No longer true,[30] the new iPhone had been declared the thinnest phone in the world
with a larger display; reducing its size from 7.6 mm to 6.9 mm and upgrading the screen size from 4 to 4.7 inches.[17][18] Even though the phone has slimmed down,
it is actually heavier. The most significant changes to the iPhone 6 line are its displays; both are branded as “Retina HD” and “ion-strengthened”.
The iPhone 6 and 6 Plus are the first iPhones to use a multiple-domain LCD panel, dubbed “dual-domain pixels”, and use a modified polarizer that makes the screen
easier to see when wearing polarized sunglasses.[31] To accommodate the larger physical size of the iPhone 6 line, the power button was moved to the side
of the phone instead of the top to improve its accessibility. Finally, the design of the iPhone 6 discontinued the use of squared-sides seen on the iPhone 4, 4S, 5, 5C,
and 5S and adopted a curved design like the one on the original iPhone, iPhone 3G, and 3GS.

Improved camera

The FaceTime camera has a new sensor that allows in 81% more light, which improves imaging in dim lighting as well as face detection.
A supplemental feature is the new burst effect, capable of taking up to 10 photos per second.
Another feature is the focus pixels “designed to speed up autofocusing by providing the sensor with more information about an image,
while improved auto image stabilization will compensate for slight amounts of motion blur and hand shakiness”.
Additionally, the new ability to control exposure will enable users to improve picture quality.

While still 8 megapixels in size, the iPhone 6’s rear-facing camera includes a new sensor which, like the camera in the iPhone 5S, has 1.5 micron pixels,
an f/2.2 aperture lens, and the ability to shoot 1080p video at either 30 or 60 frames per second. The camera also includes phase detection autofocus,
and can record slow-motion video at either 120 or 240 frames per second. The iPhone 6 Plus camera is nearly identical, but also includes optical image stabilization.
The front-facing camera was also updated with a new sensor and f/2.2 aperture, along with support for burst and HDR modes.[17][18]


The new Apple A8 chip works alongside an M8 coprocessor which continuously processes data from the following sensors: accelerometer, compass, gyroscope, and a barometer.
The barometer senses air pressure to determine relative elevation, and is used in the iPhone 6 to “measure stairs climbed or hills conquered”.
The accelerometer is able to measure distance covered while walking and running, with the use of GPS locating the user’s movements.
In addition to distinguishing whether the individual is stationary or on the move, the coprocessor works with the gyroscope to detect when the user is in a moving vehicle.
