The images published by Nowhereelse.fr highlight the front, back and the edges of the shell which is made of one piece, like the last two iPhones.
The left side of the shell features the standard mute switch and elongated volume controls.
On the right there is a SIM tray as well as the power button, which Apple allegedly moved from the top to the bottom of the device to increase operability.
The hole for the camera flash is round and not oval as on the iPhone 5S.
Worth noting is the fact that the Apple logo on the back is no longer drawn but carved.
The report notes that Cupertino could be planning to embed an indicator light that will illuminate for new messages, alerts or missed calls.
According to rumors, Apple will introduce a 4.7-inch smartphone in September, while a 5.5-inch phablet version will arrive at the end of this year.
