Tracing the History of iPhone: A Timeline of Evolution from the First Generation to the Latest Models

Since its announcement by then-Apple CEO Steve Jobs on January 9, 2007, the iPhone has consistently been at the forefront of the smartphone market, driving its evolution. Its history of evolution is not merely the advancement of a device; it has profoundly influenced our communication, access to information, and even our lifestyle itself. Each new model announced annually incorporates new technologies and features, enhancing the user experience.

This section will explain how the iPhone came into being and how it evolved to its current form. Understanding what each era of iPhone brought and what impact it had is not only useful as knowledge but also helps us re-recognize the "greatness" of the iPhone we hold today. Furthermore, when considering the purchase of a used iPhone, this historical background will be an important clue in determining which model from which period suits your needs. By tracing the evolutionary footsteps of successive iPhones, you will surely find hints to discover the optimal device for you.

The Birth and Innovation of the Original iPhone (2007-)

Announced by Steve Jobs on January 9, 2007, the original iPhone sent shockwaves around the world as "three revolutionary products." It was a device that combined a "widescreen iPod with touch controls," a "revolutionary mobile phone," and a "breakthrough internet communications device," overturning the conventional wisdom of the mobile phone market at the time. The multi-touch interface, which minimized physical buttons and allowed for intuitive finger operation, was truly revolutionary. The full browser that could view websites like a PC, the display that beautifully showed photos and music, and the sophisticated design captivated many people.

The foundation laid by this first-generation iPhone became the standard for subsequent smartphones and the cornerstone of the indispensable mobile devices in our modern lives. The close collaboration between software and hardware provided a user experience previously unseen, leading to the advent of the App Store and becoming the origin of the explosive growth of the mobile app economy.

Arrival in Japan and the Period of Popularization (iPhone 3G/3GS/4/4S)

On July 11, 2008, the iPhone 3G finally landed in Japan, creating a significant wave in the Japanese smartphone market. 3G communication support sped up internet access, and GPS functionality was enhanced. Above all, the opening of the App Store was a decisive turning point. With a wide variety of apps available on the iPhone, it evolved beyond a mere phone into a "personal tool" whose functions could be extended to meet user needs. This led to widespread recognition of the convenience and potential of smartphones even in Japan, where feature phones were previously dominant.

The subsequent iPhone 3GS, released on June 19, 2009, significantly improved processing speed and added video recording and voice control for a more comfortable user experience. On June 24, 2010, the iPhone 4, with a redesigned exterior, appeared. Its high-definition "Retina display" offered unprecedented beauty, and "FaceTime" video calls were made possible with the front-facing camera. The iPhone 4S, released on October 14, 2011, featured the "Siri" voice assistant, making interaction with the iPhone even more natural. These models were the driving force behind the widespread adoption of the iPhone beyond early adopters to the general public, laying the groundwork for modern smartphone culture.

The Era of Large Screens and Diversification (iPhone 5 Series/6 Series)

The 3.5-inch screen of the iPhone 4S and earlier models fueled a growing demand for "larger screens" as smartphones became more widespread. Responding to this, the iPhone 5 was released on September 21, 2012. Its display expanded vertically to 4 inches, allowing more information to be shown at once. Furthermore, the small, reversible "Lightning connector" replaced the traditional 30-pin connector, making charging and data transfer easier. Support for LTE, a high-speed communication standard, significantly improved internet usage on the go. The design also featured aluminum material, making it thinner and lighter.

Then, on September 19, 2014, an even bigger change arrived with the launch of the iPhone 6 and iPhone 6 Plus. These models featured significantly larger screens, 4.7 inches and 5.5 inches respectively, setting them apart from previous iPhones and strongly capturing the demand of users seeking large-screen smartphones. This increase in size dramatically enhanced mobile entertainment experiences such as video viewing, gaming, and web browsing. Additionally, the introduction of the contactless payment service "Apple Pay" created a new, highly convenient use case where the iPhone served as a wallet. During this period, the iPhone solidified its position as a "multi-functional mobile device" deeply integrated into our daily lives, moving beyond being just a communication tool.

Water Resistance, FeliCa Support, and the Advent of iPhone X (iPhone 7/8/X)

※iPhone X series released in 2017

On September 16, 2016, the iPhone 7 and iPhone 7 Plus were released, marking a new milestone in iPhone history. Most notably, they were the first iPhones to support IP67-rated water and dust resistance. This reduced concerns about water damage and dust intrusion in daily life, making them safer to use in more active settings. In the Japanese market, a significant news was the support for FeliCa (Osaifu-Keitai), long considered a privilege of Android smartphones. This allowed users to register IC cards for transportation and credit cards via Apple Pay, enabling payments and ticket gate passage by simply holding up their iPhone, dramatically improving convenience for Japanese users.

On the other hand, the iPhone 7 series saw the abolition of the long-familiar 3.5mm headphone jack, prompting a shift to Lightning connectors or wireless earphones. This move sparked controversy but ultimately accelerated the expansion of the wireless earphone market.

Then, on November 3, 2017, the iPhone X, launched to commemorate the iPhone's 10th anniversary, became a groundbreaking model that profoundly influenced subsequent iPhone designs. Its full-screen design, achieved by removing the home button and maximizing the display, along with the introduction of the Face ID facial recognition system, revolutionized the user interface. Simultaneously, the iPhone 8 and iPhone 8 Plus, released on September 22, 2017, adopted a glass back design, enabling wireless charging while retaining the iPhone 7 series' aesthetic. This improved charging convenience. These models are now popular in the used market, offering an excellent balance of performance and price.

Camera Performance and 5G Support (iPhone 11/12 Series)

※iPhone 11 series released in 2019

The iPhone 11 series, launched on September 20, 2019, elevated smartphone camera performance to a new level. The iPhone 11, in particular, adopted a dual-camera system with a wide-angle and ultra-wide-angle lens, allowing for a broader field of view in photos. The introduction of "Night mode," which enabled beautiful photos even in low-light conditions, overturned previous notions of smartphone camera capabilities. The professional-grade iPhone 11 Pro and iPhone 11 Pro Max featured a triple-camera system including a telephoto lens, achieving expressive power rivaling that of single-lens reflex cameras. The A13 Bionic chip significantly enhanced photo and video processing capabilities, enabling more creative expression.

Then, on October 23, 2020 (iPhone 12/12 mini on November 13 of the same year), a major transformation in the smartphone market was brought about by 5G communication support. The iPhone 12 series, with all models supporting 5G, allowed users to experience ultra-fast, low-latency communication on their iPhones. This made large data downloads, high-quality video streaming, and online gaming more comfortable than ever before. The design was also refreshed with a flat, angular frame reminiscent of the iPhone 4, and new technologies such as MagSafe and the LiDAR scanner (Pro models) were introduced. The LiDAR scanner, specifically in the Pro models, improved AR (augmented reality) experiences and autofocus performance in low light, hinting at future possibilities. These models remain attractive choices for users seeking essential high-speed communication for modern lifestyles and further advancements in photo and video capture.

Evolution of Latest Models and Future Outlook (iPhone 13/14/15/16 Series)

※iPhone 14 series released in 2022

The evolution of the iPhone continues relentlessly. In the iPhone 13 series, launched on September 24, 2021, the notch (the cutout at the top of the screen) was miniaturized, further expanding the display area. Pro models featured a "ProMotion display" with up to a 120Hz refresh rate, making screen scrolling and content display incredibly smooth. Furthermore, the introduction of "Cinematic mode" allowed users to apply movie-like depth-of-field effects to videos, making it easy for anyone to shoot professional-looking footage.

With the iPhone 14 series on September 16, 2022, a groundbreaking UI called "Dynamic Island" was introduced in the Pro models. This feature dynamically changes the shape and size of the cutout at the top of the screen according to notifications and activities, significantly enhancing the user experience. The Always-On display and a high-performance 48MP main camera were also major advancements in the Pro models. Safety features such as Crash Detection and Emergency SOS via Satellite were enhanced, further protecting our lives.

Then, with the iPhone 15 series on September 22, 2023, Dynamic Island was finally incorporated into all models, and the charging port was changed from Lightning to the versatile USB-C. This allowed for a common cable to be used across devices such as iPhone, iPad, and MacBook, greatly improving convenience. Pro models adopted aerospace-grade titanium material, achieving lightweight and high durability. The mute switch was replaced by an "Action Button," offering users customization by allowing them to assign any desired function.

Furthermore, the iPhone 16 series, released on September 20, 2024, features the A18 chip (A18 Pro chip for Pro models) which supports "Apple Intelligence" for more advanced AI processing. This further enhances complex task processing and personalized experiences on the device. The standard iPhone 16 and iPhone 16 Plus models are newly equipped with a "Camera Control Button" for more intuitive photography, and the Action Button is also available on all models. The Pro models feature even thinner bezels, expanding the display area. Video recording capabilities have seen remarkable evolution, with support for 4K120fps video recording for professional-level footage and Wi-Fi 7 support for high-speed wireless communication, delivering cutting-edge performance for all scenarios, from professional use to daily life.

These latest models continue to evolve in various aspects, including improved AI processing capabilities, further advancements in camera performance, and enhanced battery efficiency. The iPhone will undoubtedly continue to incorporate new technologies and features to make our lives richer and more convenient. Today, these relatively newer generation iPhones are also available in the used market, increasing opportunities to acquire the latest features at an affordable price.

Key Features and Spec Comparison of Historical iPhone Models

Each iPhone model has undergone its own unique evolution, reflecting the needs and technological trends of specific periods. From CPU performance improvements and enhanced camera quality to advancements in display technology and extended battery life, it has undergone a dizzying history of evolution. By comparing these key features, you can identify what each model "excels at" and what "purposes it is suited for." Especially for those considering purchasing a used iPhone, these spec comparisons will be extremely helpful in choosing the optimal model for your needs.

Here, we have summarized the key features and evolution points of the specifications of representative historical iPhone models in an easy-to-understand format. Even though they are all "iPhones," there are significant differences in performance and features across generations. Please use this as a reference to determine which model is best for you, considering your lifestyle and budget. PRODIG offers a wide range of used iPhones from various generations, and understanding the characteristics of each model will enable you to make a smarter choice.

Representative iPhone Models of Each Generation

While new iPhone models are released every year, several representative models stand out as particularly memorable or influential to many users. For instance, the iPhone 4, which was the first to feature the high-definition Retina display, delivered a level of screen beauty that revolutionized previous standards. The high-performance iPhone SE (1st generation), despite its compact size, was strongly favored by users seeking a small model. Moreover, the iPhone X, which abolished the home button and introduced Face ID and a full-screen design, set the direction for subsequent iPhone designs.

These representative models symbolize Apple's technological ambitions and its response to market demands during their respective eras. For example, the larger screens of the iPhone 6/6 Plus captivated users who prioritized video viewing and gaming experiences, expanding the new possibilities of smartphones. The water and dust resistance and FeliCa support of the iPhone 7/7 Plus significantly enhanced daily convenience, solidifying the iPhone's position in the Japanese market. The 5G compatibility in the iPhone 12 series heralded the arrival of the high-speed communication era, further promoting the use of large-volume content. And the iPhone 16 series has evolved into a more personal and powerful device with support for the cutting-edge AI feature, "Apple Intelligence." Understanding the characteristics of these models is extremely important for clarifying what kind of iPhone you are looking for now. For example, if you prioritize photography, models from the iPhone 11 series onward with significantly improved camera performance would be suitable. If you want to comfortably play the latest games, a model with a newer A-chip would be better. If you want a convenient secondary device, a cost-effective SE series model might be ideal. The optimal choice varies depending on your purpose.

Points of Evolution: CPU, Camera, Display, Battery

The evolution of the iPhone has been underpinned by significant advancements in key components: CPU (processor), camera, display, and battery. Understanding how these elements have evolved reveals the kind of experience each generation of iPhone can offer.

CPU

Apple's proprietary A-series chips, installed in iPhones, have significantly improved their performance each year. From the early A4 chip to the latest A18 Pro chip, processing speeds have increased exponentially, allowing even complex apps and graphically demanding games to run smoothly. The iPhone 16 series, in particular, features chips compatible with Apple Intelligence, dramatically boosting AI processing capabilities. This makes it possible to perform tasks that were once only possible on PCs, such as photo and video editing and AR (augmented reality) applications, on the iPhone.

Camera

While early iPhone cameras were simple, they have evolved to the point where they can capture professional-level photos. A wide range of features has been added, including dual and triple cameras, LiDAR scanners, Night mode, Portrait mode, and Cinematic mode, enabling beautiful photos and videos in any situation. The iPhone 16 series features a 48MP main camera even in standard models and supports spatial video recording. The Pro models can record 4K120fps video, marking remarkable advancements in video recording capabilities, to the extent that they are used in professional video production.

Display

This is an area that has seen significant evolution. From the original to the Retina display, and then to OLED (Organic Light-Emitting Diode) displays, resolution, color reproduction, and contrast ratio have dramatically improved. The full-screen design from the iPhone X onwards and the smooth display provided by ProMotion technology in Pro models have greatly enhanced the visual experience. The iPhone 16 Pro models feature even thinner bezels, maximizing the display area.

Battery

With devices becoming more high-performing, battery life has always been a critical challenge. Apple has consistently improved battery life year after year through power-efficient chips and optimized battery capacity. The introduction of wireless charging and MagSafe has also enhanced charging convenience. The iPhone 16 series also boasts improvements in battery performance.

These advancements have infinitely expanded what we can do with an iPhone, enabling a richer digital life. When choosing a used iPhone, considering these evolutionary points will help you find the model with the optimal performance for your usage.

Here, you'll find a table comparing the size, resolution, and weight of major iPhone models. Please compare and consider while imagining your specific usage scenarios, such as the size of your hand, how you carry it, and screen visibility.

OS Updates and Support Period

When choosing an iPhone, iOS updates and the support period are extremely important. Apple is known for providing the latest iOS updates to older iPhone models for several years. This ensures that new features and security patches are applied, allowing you to continue using your device safely and comfortably. However, support does not last forever. Generally, the OS update support period for iPhones is said to be about 5 to 7 years from release.

For example, the iPhone 8 and iPhone X were released in 2017, but as of 2024, they may not support the latest iOS version and may only receive some security updates. If OS updates stop, new apps may become unusable, and security risks may increase.

When purchasing a used iPhone, it is very important to check which iOS version the model you are considering supports and for how long updates are likely to be provided in the future. At PRODIG, you can also check the OS version in the product information for used iPhones. Even older OS models are often sufficient for basic uses such as web browsing, calls, and SNS, but if you want to play the latest games or use advanced apps, choosing a newer model is safer.

Tips for Choosing a Used iPhone: Learning from History to Select the Best Model

Tracing the history of the iPhone reveals that each model has undergone its own unique evolution. This rich lineup offers a diverse range of choices, not only for new devices but also in the used market. For those who want to smartly acquire a smartphone with "good cost performance," a used iPhone is a very attractive option. However, many may feel "anxious about used products." Here, we will explain the key points for safely choosing the best used iPhone, leveraging the knowledge gained from the history of the iPhone. Understanding the evolution of past models will help you concretely imagine which generation of iPhone aligns with your current needs.

At PRODIG, we conduct thorough inspections and quality control to ensure that our customers can purchase used iPhones with peace of mind. We offer a wide range of models, from older to relatively newer ones, so you are sure to find the perfect device for your use and budget. Refer to this section to take the first step towards acquiring a used iPhone smartly and confidently.

Assessing the Balance Between Performance and Price

The most important thing when choosing a used iPhone is to assess the balance between your usage, "performance," and "price." The latest models offer high performance, but they tend to be expensive. On the other hand, models from a few generations ago can be obtained at a much more affordable price than new ones, but you need to determine if their performance and features meet your current needs.

For example,

• If your primary use is basic calls, SNS, and web browsing: A model with good battery life and a clear screen is recommended. Models like the iPhone 8, iPhone X, or iPhone SE (2nd generation/3rd generation) can be used comfortably even if they are older models. These models are often found at reasonable prices in the used market and offer excellent cost performance.

• If you prioritize photo and video shooting: Models from the iPhone 11 series onwards, which have significantly improved camera performance, are recommended. In particular, the iPhone 11 Pro and iPhone 12 Pro series feature advanced camera functions such as Night mode, ultra-wide-angle lens, and LiDAR scanner, and their used prices have become more affordable. The latest iPhone 16 series also supports spatial video recording, enabling an even more advanced shooting experience.

• If you want to enjoy the latest games and AR apps, or use it for a long time: Models equipped with a relatively new A-series chip (A13 Bionic or later) are comfortable. The iPhone 13 series onwards, or the iPhone SE (3rd generation) with the A15 Bionic chip, are good candidates. In particular, the A18/A18 Pro chip in the iPhone 16 series offers even higher AI processing and performance with Apple Intelligence support. It is also likely to support future OS updates for a longer period.

By understanding the history of the iPhone and the evolution points of each model, you can clarify "what is important to you" and find the optimal used iPhone with the right performance without unnecessarily choosing an expensive model. PRODIG also provides detailed spec information for each model, so please use it for comparison and consideration.
