The iPhone has changed significantly since the iPhone 5 arrived in 2012. Apple has gradually transformed it from a compact smartphone with a four-inch display into a powerful platform for communication, photography, video creation, gaming, productivity, and personal computing.
Every generation has introduced a different combination of improvements. Some models changed the physical design, while others introduced important technologies such as Touch ID, Face ID, wireless charging, multiple-camera systems, 5G, MagSafe, Dynamic Island, USB-C and Apple Intelligence.
This complete iPhone history explains the most important developments from the iPhone 5 generation to Apple’s latest iPhone lineup.
iPhone 5 Series
Apple introduced the iPhone 5 in September 2012 with a taller four-inch Retina display, an A6 chip, LTE connectivity and a thinner aluminum design. It was also the first iPhone to use the smaller Lightning connector instead of Apple’s older 30-pin connection.
The iPhone 5c followed with a colorful polycarbonate body, while the iPhone 5s introduced Touch ID and Apple’s first 64-bit mobile processor. The iPhone 5s became especially important because fingerprint authentication continued to appear on many later iPhone models.
iPhone 6 and iPhone 6 Plus
The iPhone 6 generation introduced much larger displays. The standard iPhone 6 used a 4.7-inch Retina HD display, while the iPhone 6 Plus offered a 5.5-inch screen. Both models featured thinner aluminum bodies, the A8 chip, and Apple Pay support.
This generation established the idea of offering a standard iPhone alongside a larger version with more screen space and stronger battery performance.
iPhone 6s and iPhone 6s Plus
The iPhone 6s family looked similar to the previous generation but introduced meaningful internal improvements. Apple added the A9 chip, stronger 7000-series aluminum, a 12MP rear camera, 4K video recording, Live Photos, and 3D Touch.
The display could detect different levels of pressure and provide additional shortcuts and interactions.
First-Generation iPhone SE
The original iPhone SE combined the compact design of the iPhone 5s with performance from the iPhone 6s generation. It featured the A9 chip, a four-inch display, Touch ID, a 12MP camera, and 4K video recording.
It became a popular choice for customers who wanted a smaller device without accepting much older internal hardware.
iPhone 7 and iPhone 7 Plus
The iPhone 7 generation introduced official water and dust resistance, stereo speakers, a solid-state Home button, and the A10 Fusion chip.
The iPhone 7 Plus also became Apple’s first iPhone with two rear cameras. Its Wide and Telephoto cameras provided optical zoom and enabled Portrait Mode with a depth-of-field effect. Apple also removed the traditional 3.5mm headphone jack from this generation.
iPhone 8 and iPhone 8 Plus
The iPhone 8 generation introduced glass backs and wireless charging while retaining Touch ID and the traditional Home-button design.
Both models featured the A11 Bionic chip, True Tone Retina HD displays, and improved cameras. The iPhone 8 Plus also supported Portrait Lighting through its dual-camera system. These models represented the final flagship iPhones built around Apple’s classic Home-button layout.
iPhone X
The iPhone X marked the beginning of the modern all-screen iPhone. Apple removed the Home button, introduced gesture-based navigation, and replaced Touch ID with Face ID.
The device featured a 5.8-inch Super Retina OLED display, stainless-steel construction, wireless charging and a TrueDepth front-camera system. The iPhone X established the design direction followed by most later flagship iPhones.
iPhone XS, iPhone XS Max and iPhone XR
The iPhone XS and XS Max refined the premium design introduced by the iPhone X. They offered OLED displays, stainless-steel frames, dual cameras and the A12 Bionic chip.
The iPhone XR used a 6.1-inch Liquid Retina LCD, an aluminum frame and a single rear camera. Despite having one camera, it could create Portrait Mode images through software processing. The iPhone XR became a popular alternative for users who wanted Face ID and modern performance in a more colorful design.
iPhone 11 Series
The iPhone 11 introduced a dual-camera system with Wide and Ultra Wide lenses. It also brought Night Mode, improved video recording, and the A13 Bionic chip.
The iPhone 11 Pro and iPhone 11 Pro Max introduced Apple’s first triple-camera system, adding a Telephoto lens to the Wide and Ultra Wide cameras. They also featured Super Retina XDR displays and stronger battery performance.
iPhone 12 Series
The iPhone 12 family introduced 5G connectivity, OLED displays across the lineup, flat edges, MagSafe and Ceramic Shield.
The range included the compact iPhone 12 mini, the standard iPhone 12, the iPhone 12 Pro and the larger iPhone 12 Pro Max.
iPhone 13 Series
The iPhone 13 generation focused on battery efficiency, camera improvements and brighter displays.
The Pro models introduced ProMotion with adaptive refresh rates of up to 120Hz. Cinematic Mode also allowed users to record video with automatic focus transitions and a depth effect.
iPhone 14 Series
The iPhone 14 family introduced the larger iPhone 14 Plus, while the iPhone 14 Pro models debuted Dynamic Island, the Always-On display and a 48MP Main camera.
The standard iPhone 14 models also added camera improvements, Crash Detection and Emergency SOS via satellite in supported markets.
iPhone 15 Series
The iPhone 15 generation replaced Lightning with USB-C. Dynamic Island became available on the standard iPhone 15 and iPhone 15 Plus, while the Pro models introduced titanium construction, the Action button and the A17 Pro chip.
iPhone 16 Series
The iPhone 16 and iPhone 16 Plus introduced the A18 chip, Camera Control, the Action button and support for Apple Intelligence.
The iPhone 16 Pro models added larger displays, more advanced cameras and the A18 Pro chip.

The iPhone 17 lineup expanded premium display, processing and camera features. The standard iPhone 17 introduced the A19 chip, a larger ProMotion display, a 48MP Dual Fusion camera system and a Center Stage front camera.
Apple also introduced the iPhone Air with a thin titanium design, while the iPhone 17 Pro models focused on advanced performance, photography and professional video production. The iPhone 17e later joined the range with the A19 chip, Apple’s C1X modem, a 48MP Fusion camera and MagSafe support.
