Beyond the upcoming iPhone 7 due to be unveiled soon, Apple is said to be planning three new smartphones for next year, including a premium device with a bold new design feature.
The tech company will make a radical overhaul of the iPhone design with a curved screen on one of the models due in 2017, the year that the iPhone celebrates its tenth anniversary, according to the Nikkei Asian Review.
A source told the newspaper: "There will be a 4.7 inch model, another that will be 5.5 inches and a premium handset that will be either 5.5 inches or larger equipped with a screen bent on the two sides."
A curved iPhone screen would be a first for the company, which has this year been hit by a slowdown in sales after nearly a decade of non-stop growth. Rival Samsung is currently the only smartphone maker to have launched a curve-screened smartphone with last year's Galaxy 6 Edge and Note Edge and this year's Galaxy 7 Edge.
Sales of smartphones declined for the first time this year as established markets reached saturation point and manufacturers find it increasingly difficult to innovate with wow-factor new features as they have in previous years.
Apple earlier this year launched a lower-end device, the SE, a pocket-size phone after finally jumping on the larger screen bandwagon last year and is due to launch the iPhone 7 this autumn.
