The iPhone 6 on release date is said to pave the way for the increased use of robust materials namely Liquidmetal, sapphire and graphene, which is a form of carbon.

Liquidmetal and sapphire are already part of the iOS supply chain - the former as SIM holder and the latter as coating for the iPhone camera lens and the Touch ID fingerprint reader. If the rumours prove true, graphene will likely debut with the iPhone 6 or the next model after it.

But what exactly are the benefits that the remarkable material will deliver to mobile device users, especially to iPhone fans? Business Insider described the coming of graphene on tech devices as attached with exciting possibilities for its strength and flexibility. The material is also highly conductive, the tech site added.

Graphene is also the thinnest material on Earth, according to Phone Reviews, which suggests that used on the iPhone, the device will attain the super-slim build that has been envisioned in numerous reports.

The same Phone Reviews report echoed graphene's high conductivity, a characteristic that on mobile devices could mean considerable energy boost.

So below are the three possible killer features that Apple will deliver if graphene is used in manufacturing the iPhone 6:

Highly efficient iPhone casing and finish

It has been rumoured that Apple will build the next iPhone with Liquidmetal as the dominant shell material that according to experts will render the device virtually indestructible. But when graphene is brought to the equation, efficiency will become part of the game.

Per Business Insider, the one-atom thin graphene is self-healing, which suggests that scruffs on a graphene-protected iPhone case will disappear over time.

Quick to charge and longer-lasting battery

As mentioned above, conductivity is one of the core attractions that are packaged with graphene use on mobile devices. This translates to swift absorption of energy and longer period of storing the same, said on Phone Review on its report.

Therefore when deployed in future iPhone and iPad models with the appropriate technology, the devices will charge up in no time and will keep humming much longer than the earlier builds.

More affordable mobile solar charging

Business Insider also pointed to the possibility of graphene taking over from platinum as the main ingredient in assembling solar cells. Should that happen, not only solar charging panel on iPhones will come true but they will also come cheap.

The likelihood, however, is graphene will not make it in time for the iPhone 6 release date this 2014 as mass production of the material will not happen anytime soon, according to Graphene Tracker.
