iPhone 12 • Unlocked vs iPhone SE (2016) • Unlocked

The iPhone 12, released in October 2020, and the iPhone SE (1st generation), launched in March 2016, represent distinct eras in smartphone design and technology. While both devices operate on Apple's iOS platform, they cater to different user preferences, primarily due to their significant age difference and resulting variations in size, display technology, and processing power. The iPhone 12 offers a more contemporary experience with advanced features, whereas the iPhone SE 2016 provides a compact form factor with foundational smartphone capabilities.

The practical lifespan and software support differ considerably between these two models due to their release dates.

• Release Timeline and Software Longevity: The iPhone SE 2016, released in March 2016, received major iOS updates until iOS 15, which was released in 2021. As of March 2026, it no longer receives significant feature updates, though security updates for older iOS versions might still be provided. The iPhone 12, launched in October 2020, is expected to receive major iOS updates until approximately 2027-2028, potentially supporting iOS 28. This means the iPhone 12 offers several more years of access to the latest software features and improvements.
• Durability and Repairability: The iPhone 12 features a Ceramic Shield front cover, designed for enhanced drop performance, and boasts an IP68 rating for water and dust resistance. The iPhone SE 2016 does not have an official water resistance rating. For repairability, the iPhone 12 received an iFixit score of 6 out of 10, indicating that while many parts are replaceable, certain component replacements (like the camera or screen) may trigger software warnings if not performed by authorized technicians. The iPhone SE 2016, being an older device, generally has simpler internal components, which could make some repairs more straightforward, though parts availability might be a consideration due to its age.
• Expected Practical Lifespan: Users prioritizing the latest software features and robust protection will find the iPhone 12 offers a longer practical lifespan. The iPhone SE 2016 is better suited for users who require a basic smartphone for essential tasks and are comfortable with an older software environment.

The performance capabilities of these two iPhones reflect the technological advancements made over several years.

• Processing Power and Responsiveness: The iPhone SE 2016 is equipped with a processor that handles everyday tasks such as web browsing, messaging, and light app usage. While it was considered powerful at its release, modern demanding applications and intensive multitasking may lead to noticeable slowdowns. The iPhone 12 features a significantly more advanced processor, providing a fluid and responsive experience across all applications, including graphically intensive games and complex productivity tools. This allows for smoother app loading, seamless multitasking, and greater efficiency.
• Storage Options and Multitasking: The iPhone SE 2016 was available with storage options up to 128GB, with some models starting at 16GB. Its internal memory capacity supports basic multitasking, but switching between numerous active applications may require apps to reload more frequently. The iPhone 12 offers larger base storage options, starting at 64GB and going up to 256GB, providing more space for apps, photos, and videos. Its greater internal memory capacity allows for more efficient multitasking, keeping more applications active in the background without performance degradation.
• Connectivity and Battery Behavior: The iPhone SE 2016 supports 4G LTE connectivity. Its smaller screen and efficient processor contributed to what was considered good battery life at the time of its release, though current users report around 4 hours of screen-on time with typical usage. The iPhone 12 introduces 5G connectivity, offering faster download and upload speeds in supported areas. However, utilizing 5G can consume more power, potentially impacting battery duration compared to 4G usage.

The visual experience is a primary differentiator, with significant advancements in display technology between the two models.

• Display Technology and Clarity: The iPhone SE 2016 features a 4.0-inch Retina IPS LCD display, offering good color accuracy and viewing angles for its time. Its resolution of 1136x640 pixels at 326 pixels per inch (ppi) provides a clear image on its compact screen. The iPhone 12 boasts a 6.1-inch Super Retina XDR OLED display, which delivers deeper blacks, higher contrast, and more vibrant colors compared to LCD technology. Its higher resolution of 2532x1170 pixels at 460 ppi results in a sharper and more detailed visual experience.
• Brightness and Viewing Experience: The iPhone SE 2016 has a typical maximum brightness of 500 nits, which is adequate for indoor use but can be challenging to view clearly in bright outdoor conditions. The iPhone 12 offers a typical maximum brightness of 625 nits and can reach up to 1200 nits for HDR content, providing superior visibility in various lighting environments, including direct sunlight. The larger, edge-to-edge display of the iPhone 12 also offers a more immersive viewing experience for media consumption and gaming compared to the smaller screen with prominent bezels on the iPhone SE 2016.
• Refresh Rate and Features: Both devices feature a standard 60Hz refresh rate, meaning the screen updates 60 times per second. The iPhone 12 includes additional display technologies like HDR, True Tone, and Wide Color (P3), which enhance the visual fidelity by automatically adjusting color and intensity to match ambient light and displaying a broader range of colors. The iPhone SE 2016 lacks these more advanced display features.

The camera systems reflect a significant generational leap, offering different capabilities for photography and videography.

• Rear Camera System: The iPhone SE 2016 features a single 12-megapixel rear camera with an ƒ/2.2 aperture, capable of capturing detailed photos in good lighting conditions. It supports features like Live Photos and 4K video recording at 30 frames per second. The iPhone 12 comes with a dual 12-megapixel camera system, including a Wide camera with a larger ƒ/1.6 aperture and an Ultra Wide camera with an ƒ/2.4 aperture. This setup allows for more versatile shooting, including wider landscape shots and improved low-light performance.
• Advanced Photography and Video Features: The iPhone 12 introduces advanced computational photography features such as Night mode, Deep Fusion, and Smart HDR 3, which significantly enhance image quality in challenging lighting conditions and improve detail and dynamic range. It also supports HDR video recording with Dolby Vision at up to 30 frames per second, providing richer colors and contrast in videos. The iPhone SE 2016 lacks these advanced features, meaning its low-light performance and dynamic range in photos and videos are more limited.
• Front Camera and Audio: The iPhone SE 2016 has a 1.2-megapixel front camera with an ƒ/2.4 aperture, suitable for basic video calls and selfies. The iPhone 12 features a 12-megapixel TrueDepth front camera with an ƒ/2.2 aperture, offering much higher resolution, improved low-light performance with Night mode, and support for Portrait mode selfies. Both devices offer decent microphone quality for calls and video recording, and their built-in speakers provide clear audio for media consumption, though the iPhone 12 generally offers a fuller sound experience.
