A new video of the upcoming rumoured iPhones surfaced online hinting on some of the specs and features of the devices.

The video was featured on AppAdvice, which compared the casings of the full-fledged iPhone 5S as well as the low cost iPhone 5C. The video showed the backplates of the devices that give consumers a clear hint on the design of the rumoured smartphones.

According to reports, iPhone 5S will come in another colour option - gold. The video showed a light gold smartphone that matches very well on the silver and white colour of iPhone 5. The full-fledged iPhone may retain the aluminium casing of the smartphone. The iPhone 5C, on the other hand, may feature a thick, polycarbonate shell.

The report goes on saying that some of the features of iPhone 5 may be still seen in the next iPhone but the new iPhone may add a dual LED flash and a redesigned home button embedded with fingerprint sensor.

The report further adds that the iPhone 5S will feature improvements on the processor as well as on the camera.

The low cost iPhone 5C will most likely come with iPhone 5 parts and features as it is reported that the device is a replacement of the current iPhone. As shown in the video, iPhone 5C will come in a multitude of fun and exciting colours. The iPhone 5C is shown in blue, but it will come in an array of colours including blue, green, red, yellow, and white.

The devices are expected to be unveiled in a special launching event on September 10 and may be released worldwide 10 days after. However, Apple has not confirmed yet the iPhone 5S and iPhone 5C release date.
