In replacing the iPhone 6, Apple fans but expect the iPhone 7 on release date to showcase compelling upgrades - both in build, which likely is leaner and lighter than the current model, specs and the mainstay killer features.

Thankfully, Serbian designer Nikola Cirkovic has rendered in his mind what the next iPhone would be and the result was shared with Business Insider (images of which are viewable here). The iPhone 7, as it plays inside of Cirkovic's brain, is nothing short of stunner that will eclipse its predecessor by leaps and bounds.

And the functionalities too can be described as killer, the way that iPhone features ought to be, snippets of which plus the visualisation are provided below:

Drop-dead finish

In designing his concept, Cirkovic obviously endeavoured to follow a design philosophy that adheres to smooth flow - very much an Apple signature - as attested by his iPhone 7 casing that is seamless on front, back and all the four edges.

The only noticeable interruptions are top and bottom lines that circles the device and even these, according to Business Insider, come with specific purpose. They serve as sensors.

It should be deliberate that the iPhone 7 will best the iPhone 6 both in functions and looks and the latter definitely is achieved by the Cirkovic concept - super-thin and paperweight, assumingly lighter than ever, but not too big and too small.

To bump off the existing model, Cirkovic is proposing is a single variant with a 5.2-inch screen profile that will meet halfway of the 4.7-inch regular iPhone 6 and the 5.5-inch iPhone 6 Plus.

The key attraction for the 5.2-inch build is ease of use and handling as the concept author aims for one-hand optimisation minus the software intervention, which was the case with the 6 Plus of today.

And the bezels around the screen, as expected, are pushed to the edge as far as possible.

Sensors

With sensors dominating the render, all the physical control buttons, save for the power switch have been eliminated. The Touch ID-enabled Home key relies on the fingerprint for most of its important functions while the volume rocker is configured in the same way.

The core function of these sensors, Business Insider said, is for the upcoming to make intelligent prediction on how to behave given a situation or condition.

"The sensors will be able to tell whether the iPhone is in your pocket or on the table. If it is, the screen will stay locked. If the phone is held up and closer to the face, the screen will automatically activate," the publication explained.

Going by the usual Apple product cycle, an S version such as the iPhone 6S is likely the centrepiece for 2015, which according to Business Insider, positions the iPhone 7 for a 2016 release date.
