Some of Apple fans who decided to skip the newest iPhone 6S and 6S Plus are looking forward to the next year’s iPhone 7, which is expected to be a major upgrade. Even though the next-gen iPhone is about a year away, rumors about it are in full swing. The latest rumor coming out of Asia claims that the iPhone 7 will sport a waterproof and dustproof design.

iPhone 7 To Boast Of Waterproof And Dustproof Design

Apple has developed the first prototype of iPhone 7

Citing a post on Chinese microblogging site Weibo, Mac Otakara reports that the next year’s iPhone is currently in the prototyping phase. The Weibo post says the iPhone 7 prototypes feature a waterproof and dustproof design as the Cupertino company is looking to make it more rugged. That is a significant departure from the previous generations of the iPhone.

iPhone 7 To Be Waterproof

Many flagship Android phone already feature a waterproof design, so it makes sense for Apple to add this extra layer of protection. The latest iPhone 6S and its bigger sibling aren’t technically waterproof, but test videos show that they are far better than older iPhones at handling water. Though the Weibo post doesn’t divulge into specifics, Apple may use water-tight gaskets, an encapsulated SoC, or apply a hydrophobic coating to sensitive components to make them waterproof.

iPhone 7 to move away from aluminum chassis

Another Weibo post by the same user claims that the iPhone 7 will move away from the aluminum chassis to a new casing material. The iPhone 6S and 6S Plus feature series 7000 aluminum alloy. It’s still unclear what the new casing material would be. Mac Otakara has learned from supply chain sources that the iPhone 7 will have a “completely flat” LCD panel.

KGI Securities analyst Ming-Chi Kuo claimed earlier this month that the iPhone 7 will be just 6mm thick, making it even slimmer than the iPad Air 2. Separately, recent reports suggest that the next year’s iPhone will be powered by a hexa-core A10 processor that will be based on 10nm or 14nm technology. Apple has roped in Intel, alongside the traditional TSMC and Samsung, to produce chips for the next-gen iPhones.

None of these rumors is confirmed. The iPhone 7 is still about a year away, so nobody except Apple knows what would go into the final device.
