That's according to the occasionally-reliable Apple blog Mac Otakara, which also claims to have obtained details about the device's design.
Although the source doesn't divulge how similar the handset will look to the 6S, they note that it will measure in the same height and width.
However, the iPhone 7 is said to be marginally slimmer than the current model thanks to the thinner LCD panel that serves as its screen.
The more slender design could also be the result of Apple remodelling the traditional headphone jack in favour of its own brand of input.
