iPhone 8 Vs iPhone X

When considering the practical lifespan of these devices, both the iPhone 8 and iPhone X offer similar longevity in terms of software support and physical resilience.

• Software Updates: Both models were released with iOS 11 and, as of March 2026, continue to receive updates, currently running iOS 16.7.15. This indicates a comparable duration of ongoing software support from the manufacturer.
• Repairability: Both the iPhone 8 and iPhone X received a repairability score of 6 out of 10 from iFixit, suggesting a moderate ease of repair for common components. While the display and battery are generally considered straightforward to replace on both, the glass back on both models is noted as being particularly challenging to repair due to strong adhesive.
• Durability Features: Both devices feature glass on the front and back, with the iPhone 8 utilizing an aluminum frame and the iPhone X a stainless steel frame. Both are rated IP67 for water and dust resistance, meaning they can withstand immersion in up to 1 meter of water for up to 30 minutes.

Both the iPhone 8 and iPhone X share the same core processing power, leading to comparable performance in many daily tasks, though differences in RAM and display technology can influence overall user experience.

• Processing Capabilities: Both smartphones are equipped with the same advanced processor, which was recognized for its robust performance at the time of their release. This allows both devices to handle demanding applications, multitasking, and graphic-intensive games smoothly.
• Multitasking and Responsiveness: The iPhone X features 3GB of RAM, while the iPhone 8 has 2GB of RAM. This additional memory in the iPhone X can contribute to slightly smoother transitions between multiple open applications and a more responsive experience during heavy multitasking.
• Battery Performance: The iPhone 8, with its 1821 mAh battery, generally provides a full day of use for many users. The iPhone X, featuring a larger 2716 mAh battery, also aims for all-day power. However, the iPhone X's larger, higher-resolution OLED display and Face ID system can consume more power, leading to real-world battery life that is sometimes comparable to or slightly less than the iPhone 8 in certain usage scenarios.

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

• Display Technology and Size: The iPhone 8 features a 4.7-inch Retina HD IPS LCD display, offering consistent color reproduction and good viewing angles. In contrast, the iPhone X boasts a larger 5.8-inch Super Retina HD OLED display, which extends closer to the edges of the device, providing a more immersive viewing experience.
• Resolution and Clarity: The iPhone 8 has a resolution of 1334x750 pixels at 326 pixels per inch (ppi). The iPhone X offers a higher resolution of 2436x1125 pixels at 458 ppi, resulting in sharper text and more detailed images. The OLED technology in the iPhone X also delivers deeper blacks and a higher contrast ratio of 1,000,000:1 compared to the iPhone 8's 1400:1, enhancing visual depth.
• Brightness and Features: Both displays offer a typical maximum brightness of 625 nits and support True Tone technology, which adjusts the display's white balance to match ambient light. The iPhone X's OLED panel also supports High Dynamic Range (HDR) content, providing a broader range of colors and improved contrast for compatible media.

While both devices are capable of capturing quality images, the iPhone X introduces a more versatile camera system, particularly for advanced photography techniques.

• Rear Camera System: The iPhone 8 is equipped with a single 12-megapixel wide-angle camera with an f/1.8 aperture and optical image stabilization. The iPhone X features a dual 12-megapixel 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 optical zoom and allows for Portrait Mode, which creates a depth-of-field effect.
• Photography Features: Both phones can record 4K video at up to 60 frames per second. The iPhone X's dual-camera setup enhances its capabilities for capturing detailed zoomed-in shots and offers Portrait Lighting, which applies studio-quality lighting effects to portraits.
• Front Camera: Both devices have a 7-megapixel front-facing camera with an f/2.2 aperture. However, the iPhone X's TrueDepth camera system allows for Portrait Mode and Portrait Lighting on the front camera, providing more creative options for selfies.

Beyond core features, several practical elements distinguish the iPhone 8 and iPhone X, influencing daily interaction and overall user experience.

• Biometric Authentication: The iPhone 8 relies on Touch ID, a fingerprint sensor integrated into the home button, for secure authentication. The iPhone X, due to its all-screen design, replaces Touch ID with Face ID, an advanced facial recognition system.
• Physical Design and Handling: The iPhone 8 maintains a more compact form factor, weighing 148 grams and measuring 138.4 x 67.3 x 7.3 mm. The iPhone X is slightly larger and heavier at 174 grams and 143.6 x 70.9 x 7.7 mm, accommodating its larger display. The iPhone 8 features an aluminum frame, while the iPhone X uses a more durable stainless steel frame.
• Connectivity and Charging: Both models support Qi wireless charging and utilize the Lightning port for wired charging and data transfer. They also share similar connectivity options, including LTE, Wi-Fi (802.11 a/b/g/n/ac), and Bluetooth 5.0.
