The iPhone 7 might be dust-proof and water-proof

A set of rumors out of the Far East on Sunday claims Apple is well into the prototyping phase of its next-generation handset, with current test models incorporating a waterproof design that could be applied to a non-metal frame. Citing a post from Chinese microblogging site Weibo, Mac Otakara reports prototype “iPhone 7” units are being produced with waterproof and dust-proof features, suggesting Apple is investigating a more “ruggedized” handset. While specifics go unmentioned, Apple could be exploring methods of transplanting technology from Apple Watch, a device specifically designed to accommodate active lifestyles. For example, iPhone 7 might sport an encapsulated system-on-chip processor and water-tight gaskets. More exotic solutions include applying hydrophobic coatings to sensitive electrical components via a vapor deposition process, or integrating silicone seals at water ingress points, according to patent filings.
