The iPhone 7 carried forward the unibody aluminum construction that had become a hallmark of Apple’s smartphone design. However, it introduced a sleeker, more integrated antenna band design. On previous models, prominent white antenna lines segmented the back panel. With the iPhone 7, these lines were subtly curved to follow the contours of the device, making them less obtrusive and contributing to a cleaner, more unified look. This redesign was a significant aesthetic improvement, presenting a more premium and seamless finish.
Materiality and Durability
Crafted from 7000 series aerospace-grade aluminum, the iPhone 7 offered enhanced durability and a premium feel. This alloy was chosen for its strength-to-weight ratio, ensuring the device could withstand everyday wear and tear without compromising its sleek profile. The finish was meticulously applied, with options including Silver, Gold, and Rose Gold, along with the introduction of two new finishes: Black and Jet Black.
The standard Black model featured a matte finish, providing a sophisticated and understated look. Jet Black, on the other hand, was a high-gloss, mirror-like finish achieved through a complex nine-step anodization and polishing process. While visually striking, the Jet Black variant was also known to be more susceptible to micro-abrasions and fingerprints, demanding a higher degree of care from its users. This dual approach to finish offered consumers distinct aesthetic choices, catering to different preferences for tactile and visual appeal.
Water and Dust Resistance
A notable advancement for the iPhone 7 was its introduction of water and dust resistance. While not fully submersible for extended periods, it achieved an IP67 rating under IEC standard 60529. This meant the device was protected against dust ingress and could withstand immersion in water up to 1 meter for 30 minutes. This was a significant practical improvement, offering greater peace of mind for users in everyday scenarios, such as accidental spills or exposure to light rain. Visually, this integration was achieved without adding bulk, demonstrating Apple’s commitment to maintaining a slim form factor while enhancing durability.
Display Technology: Sharper, Brighter, and More Responsive
The display remained a focal point of the iPhone 7’s design, offering a visual experience that was both familiar and improved. Apple continued to utilize its Retina HD display technology, providing excellent color accuracy and sharp text.
Screen Size and Resolution
The iPhone 7 featured a 4.7-inch display with a resolution of 1334 x 750 pixels, resulting in a pixel density of 326 pixels per inch (ppi). This resolution was standard for many smartphones at the time and delivered crisp visuals for most common tasks, including browsing, app usage, and media consumption. The larger iPhone 7 Plus model featured a 5.5-inch display with a 1920 x 1080 pixel resolution, offering a higher pixel density of 401 ppi for even greater sharpness.
Color Accuracy and Brightness
A key improvement in the iPhone 7’s display was its enhanced color gamut and brightness. Apple introduced wide color support, bringing P3 cinema-standard color to the iPhone. This meant a broader spectrum of colors could be displayed, resulting in more vibrant and lifelike images and videos. The display was also brighter, reaching up to 625 nits of maximum brightness, which significantly improved outdoor visibility and made content easier to see in direct sunlight. This enhanced visual fidelity contributed to a more immersive and enjoyable user experience.
The Absence of the Headphone Jack
One of the most significant design changes that impacted the visual and functional aspect of the iPhone 7 was the removal of the 3.5mm headphone jack. This decision, while controversial, allowed Apple to achieve a slimmer profile and improve water resistance. Visually, this meant the bottom edge of the phone had a cleaner appearance, with only the Lightning port and speaker grilles. Users now had to rely on the Lightning port for wired audio or utilize Bluetooth wireless headphones, such as Apple’s own AirPods, which were introduced concurrently. This removal was a bold move that signaled a shift in how users would interact with their devices for audio output.
Camera Integration: Enhanced Imaging Capabilities
The iPhone 7’s camera system saw notable advancements, particularly in its ability to capture higher-quality photos and videos. The design integration of the camera module was also refined.
Rear Camera: Optical Image Stabilization and Larger Aperture
The rear camera on the iPhone 7 was a 12-megapixel sensor. A key improvement was the inclusion of optical image stabilization (OIS), a feature previously reserved for the larger iPhone Plus models. OIS works by physically moving the camera lens to counteract hand-shake, resulting in sharper photos and smoother videos, especially in low-light conditions. This was a significant upgrade that directly impacted the visual output of the camera.
Furthermore, the iPhone 7 featured a new, faster ƒ/1.8 aperture. A larger aperture allows more light to enter the camera sensor, which is crucial for low-light photography. This improved aperture, combined with the improved sensor and OIS, meant the iPhone 7 could capture more detailed and less noisy images in challenging lighting environments. The camera bump, while still present, was subtly redesigned to integrate more smoothly with the device’s unibody construction, minimizing its visual protrusion.
Front Camera: Improved Selfies
The front-facing FaceTime HD camera also received an upgrade. It boasted a 7-megapixel sensor with a wider color capture and the ability to record 1080p video. This enhancement allowed for sharper and more vibrant selfies and video calls, contributing to a better overall visual communication experience. The integration of this improved front camera continued Apple’s focus on enhancing the user’s ability to capture and share their experiences.
The iPhone 7 Plus: Dual Cameras and Portrait Mode
The iPhone 7 Plus introduced a dual-camera system, a feature that significantly distinguished it from its smaller sibling and offered advanced photographic capabilities. This dual-lens setup had a profound impact on the device’s visual appeal and functionality.
Dual-Lens System: Wide and Telephoto
The iPhone 7 Plus featured two 12-megapixel cameras on the rear: a wide-angle lens (similar to the one on the iPhone 7) and a telephoto lens. The telephoto lens provided 2x optical zoom, allowing users to get closer to their subjects without sacrificing image quality. This optical zoom capability was a significant step forward for smartphone photography, offering greater creative control over framing and composition. Visually, the dual-lens system was immediately recognizable, with two distinct circular lenses housed within a slightly larger camera module.
Portrait Mode and Depth Effects
The most celebrated feature enabled by the dual-camera system was Portrait Mode. This mode utilized computational photography to simulate the shallow depth-of-field effect commonly achieved by professional cameras with large-aperture lenses. By analyzing the scene and distinguishing between the subject and the background, Portrait Mode could intelligently blur the background, making the subject stand out. This created a professional-looking, artistic effect that was highly sought after. The ability to achieve this visually striking depth-of-field effect directly from a smartphone was a major technological and design achievement for the iPhone 7 Plus.
In conclusion, the iPhone 7, while building upon the established design language of its predecessors, presented a series of thoughtful refinements. From the sleeker antenna bands and enhanced water resistance to the improved display technology and the significant advancements in its camera systems, particularly the dual-lens setup on the Plus model, the iPhone 7 offered a visually compelling and functionally superior experience.
