The iPhone 13 and its predecessors are more than just pretty phones. With their range of functions – from telephone to web browser, from music player to mobile gaming device to advanced security measures – the iPhone feels more like a computer that fits in your pocket and your hand than a mobile phone.

Physically, the iPhone 13 series somewhat resembles the iPhone X, XS series and XR or iPhones 11 and 12. However, it is vastly different from previous models such as the iPhone 8, iPhone 6S series and others.

The main differences between the iPhone X through iPhone 13 series and earlier models are that the recent models have nearly edge-to-edge displays and a notch at the top of the screen. The notch houses the iPhone’s Face ID facial recognition system. Additionally, the phones have glass on both the front and back, have wrap-around antennas that wrap around the outside of the phone (which caused antenna issues on older models), and are slightly thinner.

Recent iPhones come in three different screen sizes — 5.8, 6.1, and 6.5 inches — all touchscreens that use multi-touch technology. Multi-touch lets users interact with items on the screen with more than one finger at a time (hence the name). It’s multi-touch that enables some of the iPhone’s most iconic features, like double-tapping the screen to zoom in or pinching and dragging your fingers to zoom out.
