There is likely to be two models which will come with larger screens that will be either 4.7 or 6 inches in size. It is rumoured the size is increasing due to the competition having mostly larger screens. Also the screens could come with an edge to edge display that could be made out of sapphire glass that will make the screen almost impossible to scratch.

The current rumours have also suggested that the camera is going to stay at 8mp. But there will be improvements in its image stablising processing and it light sensors that will make night shots even less grainy.  

The Australian blogger Sonny Dickson claims that the iPhone 6 will also be only 5.6 millimeters thick and will have an ultra-retina display with a pixel density of 389 ppi. This would be a significant improvement over the iPhone 5s. In addition he claims that the new A8 processor will be clocked at 2.6 GHz, tweeted Dickson. The Australian blogger has been quite accurate in the past with his predictions.

The processor of the next iPhone 6 (“iPhone Air”) will probably still be manufactured by Samsung. However its worth noting that the contract between Samsung and Apple is now over  reports ZDNet Korea. The A8 processor for the Apple iPhone 6 is likely to have a 64-bit chip architecture and  2GB of RAM.

Finally according to the latest rumours, the release date is likely to be either September or October as its been for a few years now.
