We're expecting a lot of great new features on the iPhone 8: a bezel-free display (well, almost), face recognition, a dual-lens camera with some special augmented reality features, and so on. One of the additions that now looks locked in as a near certainty is wireless charging.

Two insider sources speaking to The Next Web say Apple is indeed going to let iPhone 8 owners charge up their handsets without the aid of wires. Add that together with all the previous rumors we've heard, and it would be a bit of a surprise if the feature didn't turn up on Apple's next flagship device.
