Since the launch of the iPhone 4s, Apple has followed a rigid yearly release schedule: a new device one year and an 's' device the next.
This year was slightly different, however, with iPhone deciding to drop the 's' and skip straight to 8.
The iPhone 8 is more of a revolution than an evolution, however. The design is mostly the same, although there are some exciting improvements.
The most interesting is the potential addition of a new screen providing a sharper resolution. The screen could also include the iPad Pro’s True Tone technology, which adjusts colours based on environmental lighting.
It also boasts the A11 Bionic chip, which Apple claim is the most advanced chip ever built into a smartphone.
