The iPhone 6 and 6 Plus

The new iPhones ditch the sharp edges for a new rounded look. The iPhones now come in two screen sizes, a 4.7" and a 5.5" variant.The larger 6 Plus is virtually identical to the iPhone 6 except for a few differences, most notably, optical image stabilization and a few other areas like battery size. Otherwise the two devices are exactly the same. Since the devices are larger, the power/sleep/wake button is moved to the right side.

The new iPhones pack a new A8 chip along with an M8 co-processor, host improved cameras and an all new NFC chip (finally) for the iPhone.

iPhone 6 PLUS

The new iPhone 6 PLUS has a bigger 5.5" screen.The screen is a 1080p IPS display, with good viewing angles and sharp text.

Apple Pay

Apple is quite late to add NFC to its phones, but it can only be used for Apple Pay. Apple Pay uses the Touch ID system to make secure payments. Apple has partnered with many leading retail brands to make the payments seamless and hassle free. Apple claims that none of the account information of the user is stored on any of Apples's servers and can't be stolen.

Cameras

The cameras on the iPhones are improved and now offer a 240 frame per second slow-motion feature. The sensors on both models are still 8 MP cameras with improved optics. The camera on the iPhone 6 has software stabilization while the 6 plus gets optical image stabilization.
