iPhone 6s • Unlocked vs iPhone SE (2020) • Unlocked

The iPhone 6S, released in September 2015, and the iPhone SE (2020), launched in April 2020, represent different generations of Apple's smartphone lineup. While they share a similar compact form factor and the familiar Home button with Touch ID, the iPhone SE (2020) incorporates significantly newer internal components, leading to substantial differences in performance, camera capabilities, and software longevity. Both devices run on Apple's iOS operating system, but their respective release dates dictate their current and future software support.

When considering the practical lifespan of these devices, their release timelines and subsequent software support are key factors. The iPhone 6S, being an older model, has reached the end of its major iOS update cycle, supporting up to iOS 15.8.7 as of March 2026. In contrast, the iPhone SE (2020) benefits from a more recent release, supporting newer iOS versions, including iOS 18.x, which extends its software longevity significantly.

• Software Longevity: The iPhone SE (2020) offers a considerably longer period of software updates, ensuring access to the latest features, security patches, and app compatibility for several more years compared to the iPhone 6S.
• Repairability: The iPhone SE (2020) has an iFixit repairability score of 6 out of 10, indicating it is moderately repairable, with some components being interchangeable with the iPhone 8. The iPhone 6S, while also featuring a design that allows for some component replacement, does not carry an official modern repairability score, but its older design can sometimes simplify certain repairs.
• Durability Features: The iPhone SE (2020) includes an IP67 rating for water and dust resistance, offering protection against splashes and brief immersion. The iPhone 6S does not have an official IP rating, making it more susceptible to liquid damage.

The performance gap between the iPhone 6S and the iPhone SE (2020) is a primary differentiator, stemming from their respective internal hardware generations. The iPhone SE (2020) features a much more advanced internal processing unit and increased memory, which translates to a noticeably smoother and faster user experience across various tasks.

• System Responsiveness: The iPhone SE (2020) handles demanding applications, complex games, and general navigation with greater speed and fluidity. Users will experience quicker app loading times and more immediate responses to touch input.
• Multitasking Capabilities: With 3GB of RAM, the iPhone SE (2020) manages multiple open applications more efficiently, allowing for smoother transitions and less frequent app reloading compared to the iPhone 6S, which has 2GB of RAM.
• Storage Options: The iPhone SE (2020) offers starting storage at 64GB, with options up to 256GB, providing more space for apps, photos, and videos. The iPhone 6S was available with 16GB, 64GB, and 128GB storage configurations.
• Battery Behavior: The iPhone SE (2020) has a slightly larger battery capacity (1821 mAh) compared to the iPhone 6S (1715 mAh). In real-world usage, the more efficient internal components of the iPhone SE (2020) generally contribute to better power management and extended usage times for many users.

Both the iPhone 6S and iPhone SE (2020) feature a 4.7-inch Retina HD display, offering a consistent viewing experience in terms of size and resolution. However, the newer iPhone SE (2020) incorporates display enhancements that provide a more refined visual output.

• Display Technology: Both devices utilize an IPS LCD panel with a resolution of 1334 by 750 pixels at 326 pixels per inch (ppi), resulting in clear and sharp images for everyday use.
• Color Accuracy and Brightness: The iPhone SE (2020) benefits from True Tone technology, which adjusts the display's white balance to match the ambient light, and supports Wide Color (P3), offering a broader range of colors for more vibrant and accurate visuals. Both displays offer a typical maximum brightness of 500 nits.
• Unique Interaction: The iPhone 6S introduced 3D Touch, a pressure-sensing technology that allowed for new ways to interact with the interface by distinguishing between light and firm presses. This feature is not present on the iPhone SE (2020).

While both the iPhone 6S and iPhone SE (2020) feature 12-megapixel rear cameras, the generational leap in internal processing and software capabilities on the iPhone SE (2020) results in a significantly enhanced photography and videography experience.

• Rear Camera Performance: The iPhone SE (2020) boasts a 12-megapixel wide camera with a wider f/1.8 aperture and optical image stabilization, which improves low-light performance and overall image clarity. It also benefits from advanced computational photography features like Smart HDR and Portrait mode, which are not available on the iPhone 6S's 12-megapixel f/2.2 camera.
• Front Camera and Video: The iPhone SE (2020) features a 7-megapixel front camera with Portrait mode and Retina Flash, capable of 1080p HD video recording. The iPhone 6S has a 5-megapixel front camera with Retina Flash and 720p HD video recording. For video, the iPhone SE (2020) supports 4K recording at up to 60 frames per second (fps) and extended dynamic range, while the iPhone 6S supports 4K at 30 fps.
• Audio Experience: Both devices offer a mono speaker output for media consumption. The microphone quality on both is suitable for calls and basic recording, but the newer processing in the SE (2020) can offer slight improvements in noise reduction during calls.
