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.
2017 should be no different, with last year’s iPhone 7 receiving some new features and a performance boost. The iPhone 7s will almost certainly be unveiled in September, alongside the iPhone 7s Plus and the iPhone 8.
As with most S models, the iPhone 7s is likely to be an evolution rather than a revolution. The design will remain mostly the same, although some exciting improvements could be in the pipe line.
The most interesting is the potential addition of a new OLED screen, which will provide a much sharper resolution. The screen could also include the iPad Pro’s True Tone technology, which adjusts colours based on environmental lighting.
Some rumours suggest the new screen will cover the iPhone 7s’ entire front panel, although this is likely to be reserved for Apple’s special 10th anniversary iPhone.
Apple could also introduce new sizes into the iPhone 7s range, with a 5 inch and a 5.8 inch model the most likely additions. If true, the 5.8 inch model would be the biggest iPhone ever.
