The rumoured iPhone 6 will be released on June 2 at the Worldwide Developers' Conference on June 2.

Apple's iPhone 6 will face off with other smartphones to be released this year. However, iPhone 6 will win with other smartphones if it packs some killer features.

According to a report from Reuters, Apple was working on two iPhone 6 models - one will pack a 4.7 inches screen panel and will succeed iPhone 5S; the other model will boast a 5.5 inches display and will start a new smartphone line that will dive in in the phablet category. Rumours also claimed that iPhone 6 features will include faster A8 processor, iOS 8, and TouchID fingerprint sensor.

Below are the top five iPhone 6 features that will beat other smartphones.

Metal Casing

iPhone smartphones have become popular to consumers because of its metal built unlike most of its rivals, especially the Samsung Galaxy handsets, packed plastic casing. Having a plastic body is claimed as one of the reasons why the mediocre iPhone 5C flopped. Knowing this, Apple has learned its lesson to keep the metal built of iPhone 6.

Sapphire Screen Display

One of the prominent rumoured features of iPhone 6 is the Sapphire screen display. Sapphire material was proven to be stronger than Corning's Gorilla Glass used in most smartphones. Moreover, a fragile panel was one of the common complaints on iPhones. This will resolve the problem and will be one of the selling points of the device.

Better Camera

iPhone 6 was also rumoured to pack a better rear shooter paired with better camera software. Apple constantly aimed to improve the photos taken in Apple devices. Other smartphones just increase the megapixels of the camera but without a better software to back it up, it was nothing

Improved TouchID Fingerprint Sensor

Apple also aimed to improve the TouchID fingerprint which debuted at the iPhone 5S last year. Reports claimed that the fingerprint sensor will add more functions and capabilities.

iOS 8

Apple will unveil the next generation of its operating system, iOS 8, next month. Just like the previous versions, the new software will be equipped with new features.
