How the iPhone evolved over the years, from the iconic 2007 original to the AI-infused iPhone 16

With the iPhone 3G, Apple added critical new capabilities such as a GPS sensor for location-monitoring, support for 3G networks, and faster performance.

But perhaps most importantly, it introduced the App Store, transforming the iPhone from just a mobile device capable of accessing the internet to a full-blown computing platform.

Today, the App Store hosts nearly 2 million apps, ushering in the booming app economy that made it possible for the Ubers and Snapchats of the world to flourish. 

The iPhone 4 represented the first major redesign of the iPhone since its launch in 2007. It had a thinner profile and a sharper shape compared to its predecessors, and featured a body made of glass with a stainless steel trim that wrapped around its edges. 

The iPhone 4 also introduced the Retina display, which has become a hallmark of Apple’s products ever since, and was the first iPhone to come with FaceTime video-calling.

While the iPhone 4 was generally well-received, it wasn’t immune to criticism, most notably because of a call reception issue that became known as “Antennagate.” Some iPhone 4 owners experienced frequent dropped calls due to an issue with the antenna when the phone was held a certain way, a problem that prevented Consumer Reports from recommending it in 2010. 

The iPhone 5 represented yet another important redesign of the iPhone.

With the iPhone 5, Apple expanded its smartphone’s screen size to four inches, a noticeable upgrade from the 3.5-inch display found on its predecessors. That was especially important considering Apple was competing with Android devices from Samsung and others that offered larger screens.

The iPhone 5 was also the first Apple smartphone to come with the Lightning charging port, which is still present on today’s iPhones. 

Apple also launched the colorful iPhone 5C that year, which was positioned as a less expensive alternative to the flagship iPhone 5S. It came in an array of bold colors, like blue, green, and yellow, and was $100 less expensive than the 5S model.

Compared to the iPhone 5S, the iPhone 5C lacked a fingerprint sensor, ran on a previous-generation processor, and had a plastic body compared to the iPhone 5S’ aluminum build. It was significant because it represented the first time Apple gave iPhone shoppers a cheaper alternative to choose from, potentially setting a precedent for devices like the cheaper iPhone XR and iPhone 11 down the line. 

The iPhone 6S and 6S Plus were a minor update to the iPhone 6 that added a new feature called 3D Touch, which made it possible to access shortcuts by pressing more deeply on the display.

Otherwise, the phone included a faster processor and a better 12-megapixel camera. 

With the iPhone 7 and iPhone 7 Plus, Apple marked the end of an era by removing the headphone jack. They were Apple’s first pair of iPhones to come without the 3.5mm port and instead required headphones to be connected through the Lightning slot. Apple also introduced its popular AirPods wireless earbuds that year.

Apple may have not been the first company to release a headphone jack-less smartphone, but it quickly became the industry standard following the iPhone 7’s launch. AirPods have skyrocketed in popularity since then too: the company sold 27 million pairs during the 2022 holiday season alone, Apple analyst Ming-Chi Kuo estimated.

The iPhone 7 Plus was also the first iPhone to include a dual camera and Portrait Mode, the feature that makes the subject of an image look sharp against a slightly blurred background. The iPhone 7 and 7 Plus were Apple’s first smartphones to come with water resistance. 

The iPhone X was a pivotal release for Apple. Launched alongside the iPhone 8 and iPhone 8 Plus, it was Apple’s first smartphone to include a nearly edge-to-edge OLED screen, support for facial recognition, and no home button.

It set the precedent for the look and feel of Apple’s current iPhones, and it was also Apple’s first smartphone to come with a $1,000 starting price. 

Apple also launched the iPhone XR alongside the iPhone XS and XS Max, which came in a wide range of colors and cost roughly $250 less than the iPhone XS.

The iPhone XR was positioned as a less-expensive alternative to Apple’s flagship iPhones, offering a full-screen design at a price that’s easier to digest than the $1,000 iPhone XS. It lacked the OLED screen and dual camera found on Apple’s iPhone XS, but was otherwise pretty similar to its pricier sibling. 

Apple’s pricier iPhone 11 and iPhone 11 Max were its first iPhones to come with a triple-lens camera: a wide-angle camera, ultra-wide-angle camera, and telephoto lens. When announcing the phone during its annual September event, the company positioned it as being the ultimate mobile camera for professional photographers and videographers.

The phone also came with a new matte finish and an overhauled camera sensor, representing a slight redesign compared to the iPhone XS and iPhone XS Max. 

Like the standard iPhone 12, Apple’s Pro models got a design upgrade that year that that gave them a stylish, high-end feel. 

The pricier models also got larger screens than their predecessors, the iPhone 11 Pro and Pro Max, as well as an improved triple-lens camera system, augmented-reality capabilities, a faster processor, and better battery life. 

The iPhone 13 Pro also got a battery-life upgrade in 2021, capable of streaming video for over 16 hours, according to Business Insider’s test. Otherwise, the 13 Pro and Pro Max offered speedier performance and best-in-class camera quality. 

The notch on these two models is pill-shaped, a significant move for Apple, which has historically opted for a more rectangular shape.

The notifications also look different and appear on the notch in what the company called Dynamic Island.

The camera features a 48-megapixel sensor instead of a 12-megapixel one, a first for Apple.

The Pro models debuted at $999.

The Pro lineup additionally rolled out a new A17 “Pro” processor, titanium frame, and a 5x zoom camera for the iPhone 15 Pro Max.

Apple also replaced its ring/silent side switch, a feature present in every iPhone since the first generation, with a customizable action button — the first new button added to the device in 16 years. Along with still being able to turn the ringer on and off, the action button can also open other applications like voice memos or the camera.

It was also announced in 2024 that this Pro line will be able to support Apple Intelligence, Apple’s new AI.

They debuted at $999.

While all iPhone 16 models run on Apple’s newest A18 processor, the Pro lineup runs on a higher-powered A18 Pro variant — which means the Pro phones are also capable of some Apple Intelligence “unique” to the high-end models. The company also said that the Pro models have the best iPhone battery life ever: the iPhone 16 Pro and Pro Max support 27 and 33 hours of video playback, respectively — four hours more than the iPhone 15 Pro line.

Apple also changed the Pro display sizes for the first time since 2020. The iPhone 16 Pro’s display increased to 6.3 inches from the iPhone 15 Pro’s 6.1 inches, and the iPhone 16 Pro Max’s display increased to 6.9 inches from the iPhone 15 Pro Max’s 6.7 inches, with slightly slimmer bezels.

The new Camera Control button can also switch between lenses and photographic styles on the Pro models. They can also capture Spatial Audio on devices that support it, like AirPods.

They start at $999.
