Further Detail


The iPhone and iPhone 4 are two iconic smartphones released by Apple Inc. that have revolutionized the mobile industry. While both devices share some similarities, they also have distinct attributes that set them apart. In this article, we will explore the various features and specifications of the iPhone and iPhone 4, highlighting their similarities and differences.

Design and Display

When it comes to design, both the iPhone and iPhone 4 showcase Apple's commitment to sleek and elegant aesthetics. The iPhone features a rounded aluminum and glass body, while the iPhone 4 introduced a more angular design with a stainless steel frame. Both devices have a home button on the front and a single camera on the back.

In terms of display, the iPhone sports a 3.5-inch LCD screen with a resolution of 320x480 pixels. On the other hand, the iPhone 4 boasts a 3.5-inch Retina display with a significantly higher resolution of 640x960 pixels. The Retina display offers a much crisper and more vibrant visual experience, making it a major upgrade over the original iPhone.

Performance and Hardware

Under the hood, the iPhone and iPhone 4 differ in terms of performance and hardware capabilities. The iPhone is powered by Apple's A4 chip, which provides decent performance for everyday tasks and smooth multitasking. It also comes with 256MB of RAM and storage options ranging from 8GB to 32GB.

On the other hand, the iPhone 4 introduced a significant upgrade in terms of performance. It features Apple's A4 chip as well, but with improved clock speed and graphics capabilities. The iPhone 4 also doubled the RAM to 512MB, resulting in faster app loading times and smoother overall performance. Additionally, the storage options were expanded to include a 64GB variant, catering to users with higher storage needs.

Camera and Photography

Both the iPhone and iPhone 4 come equipped with cameras, but the iPhone 4 takes a leap forward in terms of photography capabilities. The original iPhone features a 2-megapixel rear camera with no flash, while the iPhone 4 boasts a 5-megapixel rear camera with an LED flash. This upgrade allows users to capture higher-resolution photos and videos, even in low-light conditions.

Moreover, the iPhone 4 introduced a front-facing camera, enabling video calls and selfies. This addition opened up a whole new world of possibilities for communication and self-expression. The front-facing camera has a resolution of 0.3 megapixels, which may seem low by today's standards, but it was a groundbreaking feature at the time of the iPhone 4's release.

Connectivity and Network

Both the iPhone and iPhone 4 support various connectivity options, including Wi-Fi, Bluetooth, and GPS. However, the iPhone 4 introduced a significant upgrade in terms of cellular connectivity. While the original iPhone supported 2G networks, the iPhone 4 was the first iPhone to support 3G networks, enabling faster data speeds and improved browsing experiences.

Furthermore, the iPhone 4 also introduced a secondary microphone for noise cancellation during calls, resulting in clearer audio quality. This improvement enhanced the overall communication experience for iPhone 4 users.

Software and Operating System

Both the iPhone and iPhone 4 run on Apple's iOS operating system, but they differ in terms of software compatibility. The iPhone originally shipped with iPhone OS 1, which was later upgraded to support newer versions of iOS up to iOS 3.1.3. However, due to hardware limitations, the iPhone 4 received more software updates and was compatible with iOS versions up to iOS 7.1.2.

This disparity in software compatibility means that the iPhone 4 had access to a wider range of apps and features compared to the original iPhone. Users of the iPhone 4 could enjoy the latest iOS enhancements, security updates, and app compatibility for a longer period.

Battery Life and Charging

When it comes to battery life, both the iPhone and iPhone 4 offer decent performance, but the iPhone 4 introduced some improvements in this area. The original iPhone had a non-removable battery with a capacity of 1400mAh, providing up to 8 hours of talk time on 2G networks.

On the other hand, the iPhone 4 featured a slightly larger non-removable battery with a capacity of 1420mAh. This upgrade, combined with software optimizations, allowed the iPhone 4 to deliver up to 14 hours of talk time on 2G networks, significantly improving the device's endurance.


In conclusion, while the iPhone and iPhone 4 share some similarities in terms of design and basic functionality, the iPhone 4 introduced several significant upgrades in performance, display, camera capabilities, connectivity, and software compatibility. The iPhone 4's Retina display, improved camera, faster processor, and expanded storage options made it a more powerful and feature-rich device compared to the original iPhone.

However, it's important to note that both devices played a crucial role in shaping the smartphone landscape and setting the stage for future iPhone models. Whether you own an iPhone or iPhone 4, both devices have undoubtedly left a lasting impact on the mobile industry and continue to be cherished by Apple enthusiasts around the world.
