As the release of the rumoured iPhone 6 nears, more concept images of the device emerged. The most recent iPhone 6 concept shows an iPhone that is 20% thinner than the iPhone 5 with an octagon-shaped body.

The new concept is courtesy of Thinkbym that include a revolutionary home button by replacing it with touch sensitive controls for the current iPhone buttons, which helps with the dramatically thinner design. We also see new features like front facing speakers and a vastly improved camera. Thinkbym makes aluminum iPhone bumper cases, which may explain the all metal look.

The iPhone 6 concept also features an 18 megapixel rear camera and it includes a ring flash to help deliver a better overall image when users need to use a flash. The designer claims there is a special low light mode and a special panorama mode on this concept.

Rumour has it that Apple's iPhone 6 will be powered by A7 quad core processor, which claimed to be faster than the previous processor. The processor will be paired with iOS 7 operating system, which is packed with new and better features.

Apple may have planned to bump the storage capacity of its smartphones. iPhone 6 is said to be coming in 16GB, 32GB, 64GB, 128GB variants.

Concept images claimed that iPhone 6 will be packed with security features. It is reported that Apple is planning to include a fingerprint sensor in Apple devices for added security. Moreover, a new approved patent from Apple will enable users to operate their devices with mere scratches or tap gesturing.

The patent discusses acoustic input devices and basically means that iOS devices could also be used with sound inputs that would be transmitted via the casing that would then correspond with certain functions.

Lastly, a new concept of iPhone is making the rounds showing the device capable of wireless charging. One of the most common complaints with Apple devices like iPhone is the fast depleting battery. However, with wireless charging, users will enjoy longer battery life.

However, Apple has not yet confirmed any of the aforementioned rumours stated above.
