iPhone 8 • Unlocked vs iPhone X • Unlocked

The iPhone 8 and iPhone X, both released in 2017, represent distinct approaches to Apple's smartphone design and technology. While the iPhone 8 maintained the classic iPhone aesthetic with a physical home button, the iPhone X introduced a radical redesign with an edge-to-edge display and facial recognition. Both devices run on the iOS operating system, offering a consistent software experience, but they diverge significantly in their user interaction and display technologies.

When considering the practical lifespan of these devices, several factors come into play, including their release timeline, software support, and physical resilience.

• Release Timeline and Software Support: Both the iPhone 8 and iPhone X were released in 2017, with the iPhone 8 launching in September and the iPhone X following in November. Both models received major iOS updates up to iOS 16.7.15, released in March 2026, indicating a similar software longevity expectation.
• Repairability: The iPhone 8 received a repairability score of 6 out of 10 from iFixit, with the screen and battery being relatively straightforward to replace. However, the glass back was noted as difficult to replace due to strong adhesive. The iPhone X also scored 6 out of 10, with its display and battery being considered repairable without affecting the Face ID hardware.
• Expected Practical Lifespan: Users can expect both devices to continue functioning for everyday tasks, though the lack of future major iOS updates means they will eventually miss out on new software features and security enhancements. The physical durability, particularly the glass back on both models, means careful handling is advisable.

Both the iPhone 8 and iPhone X share the same core processing power, but differences in RAM and display technology can subtly influence their real-world performance for various tasks.

• Processor Capabilities: Both devices are powered by the A11 Bionic chip, which provides smooth performance for everyday applications, multitasking, and gaming. This chip was designed to handle demanding tasks efficiently.
• RAM and Multitasking: The iPhone 8 comes with 2GB of RAM, while the iPhone X features 3GB of RAM. This additional RAM in the iPhone X can allow for more applications to remain open in the background without needing to reload, potentially offering a slightly smoother multitasking experience for heavy users.
• Storage Options: Both models were available with 64GB and 256GB storage capacities, providing ample space for apps, photos, and videos for most users. The iPhone 8 also had a 128GB option.

The display is one of the most significant differentiators between the iPhone 8 and iPhone X, impacting visual experience and overall device interaction.

• Display Technology and Clarity: The iPhone 8 features a 4.7-inch Retina HD LCD display with a resolution of 1334x750 pixels, resulting in a pixel density of 326 ppi. In contrast, the iPhone X introduced a 5.8-inch Super Retina HD OLED display with a higher resolution of 2436x1125 pixels and a pixel density of 458 ppi. The OLED technology in the iPhone X provides deeper blacks and a significantly higher contrast ratio (1,000,000:1) compared to the iPhone 8's LCD (1,400:1).
• Brightness and Color: Both displays offer True Tone technology, which adjusts the white balance to match ambient light for a more natural viewing experience. Both also support wide color (P3) and have a typical maximum brightness of 625 nits, ensuring good visibility in various lighting conditions.
• Viewing Experience: The iPhone X's larger, edge-to-edge OLED screen provides a more immersive viewing experience, especially for media consumption, despite the device being only marginally larger than the iPhone 8.

The camera systems on the iPhone 8 and iPhone X offer different capabilities, particularly in terms of hardware and advanced features.

• Rear Camera System: The iPhone 8 features a single 12-megapixel wide-angle camera with an f/1.8 aperture and optical image stabilization. The iPhone X, however, boasts a dual 12-megapixel rear camera system, including a wide-angle lens (f/1.8) and a telephoto lens (f/2.4), both with optical image stabilization. This telephoto lens enables 2x optical zoom and enhances Portrait Mode capabilities.
• Photography Performance: Both phones capture clear photos in good lighting. The iPhone X's dual camera system provides more versatility, particularly for zoomed shots and portraits with depth effects, especially in challenging lighting conditions. Both can record 4K video at up to 60 frames per second.
• Front Camera and Features: Both devices have a 7-megapixel front-facing camera with an f/2.2 aperture. The iPhone X's TrueDepth camera system, however, enables advanced features like Portrait Mode selfies and Animoji, which are not available on the iPhone 8.
