It may still be some time before we see the iPhone 6, but Apple has already picked their next display, according to a recent issue of Mac Fan magazine. The article suggests Apple will once again boost the size of the screen to five-inches, fitting in with all the Android offerings.
This is a big leap from the 1336 x 640 resolution currently on the iPhone 5S, a little redundant compared to the 1080p offerings on Android and Windows Phone. Apple knows they need to get into the specs game to compete with Samsung and other mobile makers, something they are already doing with the 64bit A7 processor.
Apple has been exploring different form factors for a while and it looks like the iPhone 6 will be the first to put it into practice, after the incremental four-inch size increase on the iPhone 5. Some reports say Apple is trying out devices up to 6-inches in size, pointing at the possibility of a phablet.
Apart from the size redesign, we do not expect any significant upgrades apart from a new processor. Apple has always added new A-chips to the new smartphone launch since the inception and we do not believe they will stop now, it is likely the A8 chip will have boosts in performance and battery consumption.
Tim Cook did say at All Things D larger smartphones were still a little underwhelming in terms of longevity, the average screen dying out after a year or two or succumbing to some sort of quality failure. Perhaps Apple is working hard with partners to make sure the five-inch display does not fail, even though the HTC One and Galaxy S4 both have pretty impressive displays that have not had major failures.
