There are twelve generations (and growing) of iPhones. With each new generation, there is a major updated release of the iOS (iPhone operating system). The first-generation iPhone was a GSM smartphone that set the standard for future iPhone designs. The iPhone 3G was the first iPhone to support 3G. The iPhone 3GS featured improved hardware and the iPhone 4 introduced a metal body, higher display resolution, and a front-facing camera.
The iPhone 4S brought Siri, a voice assistant. The iPhone 5 was taller than the aforementioned versions and featured a revamped lightning connector. 2013’s iPhone 5S introduced a fingerprint reader and improved hardware. The iPhone 5C was a cost-effective version that featured a plastic body instead of metal.
The iPhone 6 and iPhone 6 Plus were larger than all previous generations of iPhone with a 4.7-and-5.5-inch (120 and 140 mm) displays respectively. The iPhone 6S brought improved hardware and pressure-sensitive touch inputs. The iPhone SE features the hardware of the iPhone 6S but was as small as the iPhone 5S.
The iPhone 7 and iPhone 7 Plus debuted in 2016 and were the first water-resistant iPhones. They also featured improved system and graphics performance, new rear dual-cameras, new colors, but dropped the signature headphone jack featured on previous versions of the iPhone.
The iPhone 8 added a glass back and a better screen and camera. The iPhone X debuted with the iPhone 8 and iPhone 8 Plus. The iPhone X was the first iPhone to have a near bezel-less design. It featured an improved camera and introduced Apple’s new facial recognition system (Face ID). However, the home button was removed and thus there was no Touch ID. In 2018, Apple debuted the iPhone XS, iPhone XS Max, and iPhone XR.
