Since the iPhone product line is responsible for 55% of Apple's revenue and 70% of its profit, the importance of the iPhone 6 can't be overestimated.

Here are six things you should know about Apple and the iPhone 6:

 

1 ) The iPhone 6 screen will be bigger… but will it be big enough?

The iPhone 6 will reportedly have a 4.7" (diagonal) screen. This is a jump up from the 4" screen of the iPhone 5. But it is still smaller than the 5.1" screen of the iPhone 5's primary competitor, the Samsung Galaxy S5. Apple is also reportedly working on a 5.5" iPhone 6, but recent reports have suggested that its release may be delayed until 2015 because of production issues.

 

2) It will have a sapphire-based screen.

The iPhone 6 is expected to have a synthetic sapphire-based screen. The good news is, sapphire is excellent at crack and scratch resistance. It also enables screens that have thinner bezels, making the useful area of the screen larger for a given size. The bad news is, sapphire is denser than the Gorilla Glass currently used on iPhones, making the device heavier.

 

3) The iPhone 6 will likely run Apple's newest operating system, iOS 8.

New operating systems always bring new features and functionality. In this case, Apple's forthcoming iWatch product is also expected to run iOS 8 (or a pared-down version) and this is expected to enable tight integration of the iWatch's expected biometric features with a companion iPhone 6 handset.
