iPhone 12 Pro • Unlocked vs iPhone 8 • Unlocked

The iPhone 12 Pro, released in October 2020, and the iPhone 8, launched in September 2017, represent different generations of Apple's smartphone evolution. While both devices operate on Apple's iOS ecosystem, the iPhone 12 Pro introduces significant advancements in display technology, camera capabilities, and overall processing power compared to the iPhone 8.

The practical lifespan of a smartphone is often influenced by its release timeline, software support, and physical durability.

• Release Timeline and Software Support: The iPhone 8, released in 2017, launched with iOS 11 and received updates up to iOS 16. However, it is no longer supported by iOS 17 or iOS 18, meaning it will not receive the latest features, security patches, or bug fixes. In contrast, the iPhone 12 Pro, released in 2020, launched with iOS 14 and is currently supported by iOS 26.4 as of March 2026, indicating a longer period of ongoing software support.
• Durability Features: The iPhone 8 features a glass front and back with an aluminum band, and is rated IP67 for water and dust resistance, allowing submersion up to 1 meter for 30 minutes. The iPhone 12 Pro enhances this with a Ceramic Shield front cover, a glass back, and a stainless steel frame, offering IP68 water and dust resistance for depths up to 6 meters for 30 minutes.
• Repairability: Both devices received an iFixit repairability score of 6 out of 10. For the iPhone 8, the screen and battery are relatively straightforward to replace, but the glass back is difficult to remove due to strong adhesive. The iPhone 12 Pro also has modular components that are generally accessible, but proprietary screws and enhanced waterproofing measures can complicate repairs.

Performance differences between these two models are notable, impacting daily usage from app responsiveness to multitasking capabilities.

• Processing Power: The iPhone 8 is powered by the A11 Bionic chip, while the iPhone 12 Pro features the A14 Bionic chip. This generational difference means the iPhone 12 Pro handles demanding applications and complex tasks with greater efficiency and speed. Users will experience faster app loading times and smoother transitions between applications on the newer device.
• Multitasking and Responsiveness: The iPhone 8 comes with 2GB of RAM, which is sufficient for general use but can show limitations with numerous apps open simultaneously. The iPhone 12 Pro, with 6GB of RAM, offers significantly more capacity for multitasking, allowing users to switch between heavy applications and games without noticeable slowdowns.
• Storage Options: The iPhone 8 was available with 64GB, 128GB, or 256GB of internal storage. The iPhone 12 Pro starts with 128GB and also offers 256GB and 512GB options, providing more space for apps, photos, and videos, especially for users who store large media files.

The display technology and characteristics vary significantly between the iPhone 8 and iPhone 12 Pro, influencing the visual experience.

• Display Technology and Resolution: The iPhone 8 features a 4.7-inch Retina HD LCD IPS display with a resolution of 1334x750 pixels, resulting in a pixel density of 326 ppi. The iPhone 12 Pro upgrades to a 6.1-inch Super Retina XDR OLED display, offering a higher resolution of 2532x1170 pixels and a pixel density of 460 ppi. The OLED technology on the 12 Pro provides deeper blacks and more vibrant colors compared to the LCD panel of the iPhone 8.
• Brightness and Color Accuracy: Both devices support True Tone technology, which adjusts the screen's white balance to match ambient lighting, and Wide Color (P3) for accurate color reproduction. However, the iPhone 8 has a typical maximum brightness of 625 nits, while the iPhone 12 Pro reaches 800 nits typically and up to 1200 nits for HDR content, offering better visibility in bright outdoor conditions and a more dynamic viewing experience for HDR media.
• Screen Size and Features: The iPhone 8 has a smaller 4.7-inch screen with a traditional bezel design and includes 3D Touch. The iPhone 12 Pro offers a larger 6.1-inch edge-to-edge display, providing a more immersive viewing experience, and replaces 3D Touch with Haptic Touch.

The camera systems of the iPhone 8 and iPhone 12 Pro show substantial advancements, particularly in versatility and low-light performance.

• Rear Camera System: The iPhone 8 features a single 12MP wide-angle camera with optical image stabilization (OIS) and an f/1.8 aperture, capable of 4K video recording at up to 60 frames per second. The iPhone 12 Pro boasts a triple-camera system, including a 12MP wide (f/1.6), 12MP ultra-wide (f/2.4), and 12MP telephoto (f/2.0) lens, along with a LiDAR Scanner. This setup provides greater photographic flexibility, including optical zoom capabilities and improved depth sensing.
• Low-Light and Computational Photography: A key differentiator is the iPhone 12 Pro's enhanced low-light performance, featuring Night mode and Deep Fusion, which are absent on the iPhone 8. These technologies allow the 12 Pro to capture significantly brighter and more detailed images in challenging lighting conditions. The LiDAR Scanner also aids in faster autofocus in low light and enables Night mode portraits.
• Video Recording and Front Camera: Both phones support 4K video recording, but the iPhone 12 Pro elevates video quality with 4K Dolby Vision HDR recording at up to 60fps, offering richer colors and improved contrast. For selfies, the iPhone 8 has a 7MP front camera, while the iPhone 12 Pro features a 12MP TrueDepth front camera with Night mode and 4K video recording, providing sharper and more detailed self-portraits, even in dim environments.
