Apple’s iPhone 7 – tipped to be released in September 2015 – is rumoured to include a built-in projector, as well as a host of other new features.

The successor to the recently released iPhone 6 and iPhone 6 Plus will also boast an improved battery pack created from ‘organic materials’ alongside the mini projector.

The battery – which will replace the current Li-on batteries used in the Apple smartphones – will provide the device with longer battery life.

The projector, meanwhile, will allow users of the iPhone 7 to project videos, presentations and photos, including films and slideshows, onto any flat surface such as a wall. Users will no longer require a separate projector in order to show media content, according to

Other new features look set to include a 3D display that does not need 3D glasses, which will form part of the technology firm’s aim to create a 3D "hardware and software ecosystem".

The screen display on the iPhone 7 is also rumoured to be reinforced by sapphire material, the likes of which was first seen in Apple Watch. This plan is thought to be part of Apple’s measures to respond to criticism over the fragile screens on the iPhone 6 and iPhone 6 Plus.
