Rumored iPhone 7 could be waterproof, making it more attractive for challenging work environments

The rumored iPhone 7 could come with a waterproof chassis, making it more attractive for use in some challenging work environments.

The waterproofing will be done by applying a special chemical coating to the device's components, a source familiar with Apple's plans told Fast Company.

In addition, the iPhone 7 will support wireless charging and include noise cancelation technology from Wolfson Microelectronics, the source related. The Apple Watch is the only Apple product that currently uses wireless charging.

The new phone will also eliminate the 3.5-millimeter headphone jack to make it even slimmer, relying instead of the Lightning cable port for sound output to wired headphones, the source said.

Apple is working with chip maker Cirrus Logic to adapt the audio chipset in the iPhone 7 to work with the Lightning port, the source said.

Some reports indicate that a set of Lightning-connected EarPod earphones will be included with the iPhone 7. But the Fast Company source said it is more likely that Apple will sell separately expensive noise-canceling, Lightning-connected earphones or headphones, possibly under its Beat brand. Other pundits expect Apple to include an adapter with the iPhone 7 to enable users to use regular 3.5mm headphones.

The source noted that Apple has previously pulled features, such as wireless charging and waterproofing technology, late in the development process. So there is no guarantee that the technologies will show up in the final iPhone 7.
