iPhone 11 Pro vs iPhone X

When evaluating the longevity of these devices, their respective release timelines and ongoing software support are key considerations.

• Software Support: The iPhone X, having been released in 2017, received major iOS updates up to iOS 16, which was released in March 2026. The iPhone 11 Pro, released in 2019, benefits from a later launch date and is expected to receive major iOS updates for a longer duration, with support extending to iOS 26 as of March 2026. This difference means the iPhone 11 Pro will continue to receive security updates and new features for a longer period.
• Physical Durability: Both devices feature a construction of glass and stainless steel. The iPhone X carries an IP67 rating for water and dust resistance, indicating it can withstand submersion in up to 1 meter of water for 30 minutes. The iPhone 11 Pro improves upon this with an IP68 rating, allowing for submersion in up to 4 meters of water for 30 minutes. While early reports suggested the iPhone X's glass back could be prone to breakage, the iPhone 11 Pro incorporated what Apple described as tougher glass, showing improved resilience in some tests.
• Expected Practical Lifespan: Users can anticipate a longer practical lifespan from the iPhone 11 Pro due to its newer components and extended software update cycle, which contributes to sustained performance and access to the latest features and security enhancements.

The internal components of these two iPhone models offer a clear progression in processing power and efficiency, impacting overall user experience.

• Processing Capabilities: The iPhone X is powered by an A11 Bionic chip, which capably handles everyday applications and multitasking. The iPhone 11 Pro features a more advanced A13 Bionic chip, providing faster CPU and GPU speeds. This translates to smoother performance for demanding applications, more fluid gaming experiences, and quicker processing of complex tasks.
• System Responsiveness and Multitasking: The iPhone X comes with 3GB of RAM, which was sufficient for its time. The iPhone 11 Pro includes 4GB of RAM, contributing to improved multitasking capabilities and allowing more applications to remain active in the background without needing to reload.
• Battery Behavior: The iPhone X has a 2716 mAh battery, while the iPhone 11 Pro features a larger 3046 mAh battery. In real-world usage, the iPhone 11 Pro offers significantly longer battery life, typically lasting around 4 to 5 hours more on a single charge compared to the iPhone X, due to both the larger battery and the more power-efficient processor.

Both the iPhone X and iPhone 11 Pro feature high-quality OLED displays, though the newer model brings enhancements in brightness and color accuracy.

• Display Technology and Resolution: Both devices are equipped with 5.8-inch OLED displays, offering deep blacks and vibrant colors. They share the same resolution of 2436 x 1125 pixels, resulting in a pixel density of 458 pixels per inch, providing sharp and clear visuals.
• Brightness Levels: The iPhone X features a Super Retina HD display with a typical maximum brightness of 625 nits. The iPhone 11 Pro upgrades to a Super Retina XDR display, offering a higher typical maximum brightness of 800 nits and a peak brightness of 1200 nits when viewing HDR content. This increased brightness improves visibility in bright outdoor conditions and enhances the viewing experience for HDR media.
• Color and Refresh Rate: Both models support True Tone technology, which adjusts the display's white balance to match the ambient light, and a wide color gamut (P3) for accurate color reproduction. Both displays operate at a standard 60Hz refresh rate.

The camera systems are a primary differentiator between these two iPhone models, with the iPhone 11 Pro introducing a more versatile setup and advanced computational photography features.

• Rear Camera System: The iPhone X features a dual 12-megapixel camera system, comprising a wide-angle lens and a telephoto lens, both with optical image stabilization. The iPhone 11 Pro elevates this with a triple 12-megapixel camera array, adding an Ultra Wide lens to the wide-angle and an improved telephoto lens. This provides greater flexibility for capturing expansive landscapes and improved zoom capabilities.
• Photography Features: Both support Portrait mode and Portrait Lighting, though the iPhone 11 Pro offers more advanced effects and Depth Control. The iPhone 11 Pro introduces significant advancements like Night mode for improved low-light photography, Deep Fusion for enhanced texture and detail, and next-generation Smart HDR for better exposure in challenging lighting conditions. The iPhone X's low-light performance is less capable in comparison.
• Video and Front Camera: Both phones can record 4K video at up to 60 frames per second, with the iPhone 11 Pro offering extended dynamic range for video and audio zoom during recording. For the front-facing camera, the iPhone X has a 7-megapixel TrueDepth camera, while the iPhone 11 Pro features an upgraded 12-megapixel TrueDepth camera capable of 4K video recording and slow-motion selfies.

Beyond core performance and display, several other features contribute to the overall user experience and differentiate these two iPhone models.

• Connectivity Options: Both devices support Bluetooth 5.0 and offer Qi wireless charging. The iPhone X supports Wi-Fi 802.11ac (Wi-Fi 5). The iPhone 11 Pro features Wi-Fi 802.11ax (Wi-Fi 6), which offers faster speeds and improved performance in congested network environments. The iPhone 11 Pro also includes an Ultra Wideband (U1) chip for enhanced spatial awareness.
• Ports and Biometrics: Both the iPhone X and iPhone 11 Pro utilize the Lightning port for charging and data transfer. Both models rely on Face ID for secure facial recognition and authentication.
• Physical Characteristics: The iPhone X measures 143.6 x 70.9 x 7.7 mm and weighs 174 grams. The iPhone 11 Pro is slightly larger and heavier at 144 x 71.4 x 8.1 mm and 188 grams. Both devices feature a glass front and back with a stainless steel frame.
