One of the differentiating features of the iPhone is its overall experience, which for the first time is available on a device with a larger screen size. Relegated to the 3,5-inch form factor for the last three generations, the iPhone 6 and iPhone 6 Plus are the first iOS devices to offer large screen real estate to users.
The iPhone 6 comes with a 4.7-inch LCD display with a pixel density of 326 PPI. The screen also has a Sapphire Crystal glass, which protects it from damages and stratches. The device also runs on the Apple iOS and the Apple A8 chipset with dual-core 1.4GHz Cyclone (ARM v8-based) processor. There is also a PowerVR GX6450 (quad-core graphics) for gaming.
This device comes with an 8-megapixel iSight rear camera. It has a large sensor and a big pixel size which allows more light to get in, resulting in low-light pictures. You can make high quality video calls using the HD front camera. The Backside Illumination Sensor (BIS) gives good quality images in low-light conditions.
iOS 8 adds some new features such as adding voice to text messages, choosing from third-party keyboards, track heart-rate and other fitness parameters, act on notifications without leaving an app, and sync the iPhone with the iPads and Macs. You could also browse through the 1,300,000 app options that are available in the App Store. iOS 8 is much more customizable when compared to earlier iterations, and you immediately get the feeling that the software ties in with the hardware s ability to redefine the iPhone line. Customizable keyboards, allowing you to install Fleksy or Swiftkey, are welcome additions that have long been requested by users.
Although there isn t much to differentiate the iPhone 6 from the 6 Plus at a hardware level other than the larger screen size, one noticeable omission on the smaller device is OIS, which is available on the 6 Plus. The reasoning for this is that the sensor was too large to fit into the body of the iPhone 6. While most users won t miss the feature on account of how good the iSight camera on the iPhone 6 is in and of itself, it would have been even better if OIS was also included.
