The standard iPhone 13 model comes with a 6.1" Super Retina XDR OLED screen with Dolby Vision, with the most powerful mobile chip to date - the Apple A15 Bionic, and three nicely capable 12MP cameras - two at the back and one at the front. The iPhone 13 is as big as the iPhone 12, but due to its larger battery and different components, it is now slightly heavier and a bit thicker. Famous for its smaller notch, the iPhone 13 is one of the most powerful smartphones on the market and a bestseller in the making.
