Are you looking forward to iPhone 7? If so, you may be surprised at just how big the changes will be.

Apple is looking to make a big splash with the iPhone 7 in 2016, and there are three changes in particular that will be big with users, according to a Forbes report.

For one thing, the new iPhone will be waterproof. That’s certainly a pretty big deal in its own right, and would certainly save the many iPhones that are lost each year after being submerged in water for whatever reason.

Of course, the iPhone 6’s are practically waterproof already. But if you aren’t willing to risk your warranty by taking your iPhone in the shower with you, iPhone 7 has you covered.

That may mean the company will have to eliminate the phone’s headphone jack, which is difficult to waterproof.

A second major change will mostly have to do with aesthetics: those stripes that wrap around your phone that essentially act as antennas so that you can receive WiFi, carrier signals, and Bluetooth. Those stripes are needed on smartphones based on aluminum.

In order to do that, it has to do something about the aluminum itself, and it is doing that by making a third big change: a “smart” aluminum body. The new body of the iPhone 7 will have compound materials that will allow wireless signals to pass through them directly, eliminating the need for the antenna stripes.

Apple’s patent from June, which describes the new material, is as follows: “Composite structures that have an appearance of an anodized bulk metal but that is non-capacitive and/or radio frequency (RF) transparent are disclosed. The composite structure can be part of an enclosure of an electronic device. The composite structure can give the enclosure a metallic look without interfering with the functioning of some electronic components of the electronic device, such as RF antennas, touch pads and touch screens.”
