iPhone 7 will use lightning port for audio output
Although many people think that the single USB-C port in a 12-inch MacBook is its biggest limitation, there are some benefits to it as well. It makes the design of this MacBook very sexy and stylish, and brings its wireless capabilities to the main stage.
This trend of making the bold decisions to accomplish the simple design is expected to continue with the future iPhones as well. According to multiple sources, the next version of iPhone will become the first with a single lighting port for data transferring, charging and audio output.
True stereo speakers
The 3.5mm headphone jack we are all familiar with will not feature in the design of iPhone 7, making it possible for the next iPhone to become even thinner. We believe that in place of the headphone jack, Apple will put the second speaker, making iPhone's speakers producing true stereo sound.
It is worth noticing that there are already some headphones with a support for lighting connector on the market, the most popular ones being the Philips M2L/27 Fidelio Premium Headphones.
Embracing the wireless future
In addition to the absence of 3.5mm headphone jack, iPhone 7 is expected to support wireless charging and have a waterproof design. Both features are already available on select Android phones for years, so, from a technological point of view, nothing is holding Apple from introducing these features into its future iPhones.
