iPhone 7 was released by Apple in September 2016. It comes with top speed, connectivity, and battery life. While it's the exact same size as iPhone 6 (5.44 by 2.64 by 0.28 inches), but slightly lighter (4.87 ounces compared to 5.04 ounces), it needs a different case because the camera is slightly below where it sits on the 6s. It seems that at least scientifically its size is the ideal one to fit most hands. The iPhone 7 has a single 12-megapixel camera on the back, and a 7-megapixel selfie camera on the front.
