On September 12, the world's most valuable company will reportedly launch three new iPhone models - a 5.8-inch iPhone Xs, a 6.5-inch iPhone Xs Max and a 6.1-inch iPhone 9/Xc/Xr that will be a successor to the iPhone 8. Last year, Apple skipped one generation to introduce iPhone 8, iPhone 8 Plus, and iPhone X (the 10th anniversary special edition).
