Other vendors have released waterproof phones in the past, but they either used nano coatings that would likely destroy the environmental ratings Apple values, or they used little flaps to protect ports that could break off and ruin the protection.
The iPhone 6s, while officially possessing nothing in the way of water resistance, has held up startlingly well to splashes and even dunks. There are rumors that the iPhone 7 will take that even further, with official "splash proofing" and perhaps even more.
Although swimming with an iPhone may not be on everyone's wish-list, those whose jobs or pastimes expose them to the elements, and even those who want to do underwater photography at shallow depths would be thrilled by the feature.
What changes can we expect in the iPhone 7 cameras?
Based on some recent acquisition, including smart camera company PrimeSense, speculation is high that Apple is working on taking even the 12 megapixel, 4K video camera in the iPhone 6s to the next level. What that means for the iPhone 7 is uncertain, though rumor has it Apple is aspiring to make the iPhone camera as good as a DSLR. That includes better low light, dynamic focus and depth of field, and potentially more.The potentially more part is currently rumored to include two lenses allowing for even more advanced image signal processing. Whether, like optical image stabilization (OIS), that would be limited to the bigger, slightly more expensive Plus model is unknown.
The second lens could be used for wide-angle shots, to add extra data for better shots, or to pull black and white information for clearer, better low-light photography.
Will the iPhone 7 have wireless charging?
Up until mid-2015, it hadn't been possible to do wireless charging—also known as inductive charging—on a phone with a metal back. Since Apple switched from the glass of the iPhone 4 and iPhone 4s to the aluminum of the iPhone 5 and later models, that effectively meant the company couldn't offer wireless charging as well.
Now methods for induction through metal are being introduced, which means it's possible Apple could keep the aluminum back and offer wireless charging. The iPhone 7 is the first iPhone Apple could launch with the feature, if the company chooses to.
If Apple is serious about removing the 3.5mm headphone jack, wireless charging would be away to let customers listen via Lightning while charging via inductive magnet.
Recent rumors have also suggested Apple is working on resonant inductive coupling, which would let devices charge even at a distance. (The greater the distance, the lower the efficiency.) Such technology is likely a year or more away, though.
