iPhone 4 vs. iPhone 4S: What's the Difference?
Edited by Janet White || By Harlon Moss || Updated on October 23, 2023
The iPhone 4 is Apple's 4th-generation smartphone, while the iPhone 4s is its upgraded successor, introducing Siri and improved hardware.
Key Differences
The iPhone 4, introduced in 2010, marked a significant design shift for Apple's smartphones, featuring a flat, glass-backed design. On the contrary, the iPhone 4s, released in 2011, maintained the same design but brought about notable internal changes.
While the iPhone 4 was appreciated for its Retina display and design overhaul, it had certain reception issues due to its antenna design. In contrast, the iPhone 4s addressed this with a revised antenna system and offered better cellular reception.
A defining characteristic of the iPhone 4s over the iPhone 4 was the introduction of Siri, Apple's voice-activated personal assistant. The iPhone 4 did not have this feature, making the iPhone 4s distinct in terms of software capabilities.
The camera system of the iPhone 4s was also superior. While the iPhone 4 came with a 5-megapixel camera, the iPhone 4s boasted an 8-megapixel camera, enhancing photo quality and low-light performance.
The iPhone 4s came equipped with a dual-core A5 chip, which meant faster performance and smoother multitasking compared to the iPhone 4's single-core A4 chip.
