I like this for the (supposed) iPhone 7; it doesn't sound exactly like POET, but then again, it's just rumour at this point....

Apple is apparently prepping something BIG for the iPhone 7. The company is said to be very keen on striking while the iron is hot –– and the iron is very hot at the moment, with record iPhone 6 and iPhone 6 Plus sales. What this rethink will entail remains to be seen, but sources are now claiming it is going to be very special indeed.

“Along with a slight shrinkage in size of the iPhone 6S’s logic board, Apple also appears to be aggressively reducing the number of chips it’s using. One section of the board that previously had in excess of 10 components has been pared down to 3 main chips, simultaneously cutting the number of parts and increasing the power efficiency of the ones that remain. Other necessary and remaining chips, such as the flash memory and CPU, notably benefit from smaller manufacturing processes that enable the iPhone 6S to offer the same or faster functionality with smaller, less power-hungry parts,” reports Apple Insider.
