Design
The iPhone 4 series featured a completely new look that was both modern and elegant, which marked a significant departure from the design of earlier iPhones. The device’s edges were framed in stainless steel, giving it a solid and premium appearance. The device had a smooth, streamlined appearance because both its front and back were made of glass. Additionally, an oleophobic coating was applied to the glass panels to lessen fingerprints and make cleaning them easier.
Display
Retina displays, which offered a significantly higher resolution than earlier models, were first used in the iPhone 4 series. The display had a diagonal measurement of 3.5 inches and a pixel density of 326 pixels per inch at a resolution of 960 x 640 pixels. Text and images appeared more detailed and sharper than ever before as a result. Additionally, the display had LED backlighting, which increased brightness and power efficiency.
Hardware
The iPhone 4 series was equipped with Apple’s A4 / A5 processor, a 1GHz chip that provided notable performance enhancements over earlier models. The device also included 512MB of RAM, which improved the efficiency and smoothness of multitasking. Users could choose between the 16GB and 64GB of storage that was offered by the device, depending on their storage requirements. Additionally, the device had a 5-megapixel camera that could record both high-quality stills and videos.
Operating System
Apple’s iOS 4 operating system, which represented a significant improvement over earlier iterations of iOS, was included with the iPhone 4 series. Multitasking, folders, and an integrated email inbox were just a few of the new features that came with iOS 4 / iOS 5. In addition, the operating system debuted iBooks, Apple’s e-book reader app, and Game Center, a gaming community where users could play games and challenge other players. FaceTime, Apple’s video calling service, was also made available in iOS 4 / iOS 5 and allowed users to make video calls over Wi-Fi.
Conclusion
For Apple’s smartphone line, the iPhone 4 series marked a significant turning point. It paved the way for subsequent iPhones and established Apple as the market leader in smartphones with its stunning design, high-resolution display, improved hardware, and updated operating system.
