Advanced haptic feedback
Apple patented a haptic feedback system — a method of providing physical response to a touch with a subtle micro-vibration, for example — back in 2012, but nothing ever came of it. The next iPhone could come with a feature that could further draw users away from the hardware keyboard crowd.

Wireless battery charging
Though it has yet to really take off, some modern phones have launched with wireless charging as its main gimmick. The likelihood of its implementation is slim, but the trend it would set could propel the technology into the mainstream in the smartphone sector.

The Nokia 1020 packs an impressive 41-megapixels snap from its high-resolution camera. And considering Apple prides its iPhone as being one of the most popular de facto point-and-click cameras on the market — albeit with a high markup — surely the company would want to capitalize on this even more? Expect more megapixels, but not mega-megapixels.
