Following the trajectory set by the iPhone 6 and 6s, the iPhone 7 represented a significant evolution in Apple's smartphone lineup, focusing on refinement rather than revolution. This update on the iPhone 7 aimed to address user feedback regarding water resistance, audio quality, and camera performance while maintaining the core design language. Released in the fall, the device quickly became a benchmark for what a mainstream premium smartphone should offer, balancing powerful internals with a polished aesthetic.
Design and Build Quality Refinements
The most immediate change users noticed was the physical redesign, which moved away from the previous year's faux-metal antenna lines. The update on the iPhone 7 featured a unibody aluminum chassis that was both stronger and more cohesive in its visual language. This construction method not only improved durability but also allowed for better integration of the glass front, creating a seamless display surface that was more resistant to everyday scratches and minor drops.
Another notable alteration was the relocation of the headphone jack, a move that sparked significant debate but was driven by a clear functional goal. By removing the traditional port, Apple was able to make the device thinner and more water-resistant, paving the way for the IP67 rating that provided peace of mind against accidental splashes and immersion. This change necessitated the inclusion of included EarPods with a lightning connector and a headphone adapter in the box, ensuring compatibility with the vast ecosystem of audio devices.
Performance and Internal Upgrades
Under the hood, the update on the iPhone 7 introduced the A10 Fusion chip, a powerhouse that significantly boosted processing and graphics capabilities. This new chip enabled smoother multitasking, faster app launches, and more efficient power management, which translated directly into improved battery life compared to its predecessor. Users experienced a noticeable difference in responsiveness, whether they were browsing the web, playing graphics-intensive games, or using demanding professional applications.
Storage options were also expanded in this generation, with configurations starting at 32GB and going up to 256GB, effectively eliminating the 16GB variant that had been criticized for being insufficient out of the box. This range ensured that users could comfortably store thousands of photos, hours of video, and a massive music library without the constant need to manage space. The RAM remained at 2GB, but the efficiency of the A10 chip meant that this memory was utilized more effectively than ever before.
Camera System Improvements
Rear Camera Innovations
The camera system received perhaps the most attention in the update on the iPhone 7, with Apple focusing heavily on low-light performance and image processing. The 12-megapixel rear sensor was larger and could capture 40% more light than the previous model, resulting in significantly cleaner photos in dim environments. The introduction of optical image stabilization (OIS) on the Plus models was a game-changer, reducing blur caused by hand tremors and allowing for sharper images at longer exposure times.
Apple also updated the lens to a six-element design and widened the aperture, which, combined with the new image signal processor, allowed for faster autofocus and more vibrant colors. The 4K video recording capability was retained and improved, making the device a capable tool for amateur videographers. Features like burst mode and slo-mo video recording were refined, providing users with more creative control over their content.
Front Camera and Portrait Mode
The front-facing camera was also updated, jumping to a 7-megapixel sensor that was wider and captured more detail, making video calls and selfies look better than ever. The software-driven Portrait Mode, initially introduced with the iPhone 7 Plus, used advanced machine learning to simulate a DSLR-like depth of field. By leveraging the A10 Fusion chip, the phone could distinguish between the subject and the background, blurring the latter to create a professional-looking bokeh effect without the need for a second lens.
