iPhone 6s • Unlocked vs iPhone SE (2016) • Unlocked

The iPhone 6S, released in September 2015, and the iPhone SE (2016), launched in March 2016, represent two distinct approaches to Apple's smartphone offerings from the same generation. While both devices share the same core processing power and operate on the iOS platform, they cater to different user preferences primarily through their physical design and screen size. The iPhone 6S offers a larger display and introduces a pressure-sensing screen technology, whereas the iPhone SE (2016) provides a more compact form factor reminiscent of earlier iPhone models.

Considering their release timelines, both the iPhone 6S and the iPhone SE (2016) have reached the end of their major software update cycles, having received support up to iOS 15. This means their practical software longevity is now limited, as they will not receive future iOS versions. Users should consider this when evaluating their long-term usability for applications that require newer operating system features.

• Software Support: Both models concluded their major iOS update cycle with iOS 15, meaning they no longer receive the latest operating system features or security updates.
• Practical Lifespan: While still functional for basic tasks, the absence of current software updates means these devices may encounter compatibility issues with newer applications and services over time.
• Repairability: Both devices feature designs that allow for component replacement, though the availability of parts and professional repair services may vary due to their age.

Both the iPhone 6S and the iPhone SE (2016) are equipped with the same internal processing unit and memory, offering comparable performance for their time. They were designed to handle everyday tasks, app usage, and light gaming smoothly when they were current devices.

• Processor Capabilities: Both phones utilize a processor that, at their release, provided a significant performance boost over previous generations, enabling smooth navigation and app launching.
• Multitasking: With 2GB of RAM, both devices can manage several applications running simultaneously, though performance may degrade with more demanding or numerous background processes.
• Storage Options: Both models were available with various storage capacities, including 16GB, 32GB, 64GB, and 128GB, allowing users to choose based on their storage needs for apps, photos, and media.

The primary distinction in screen quality between these two models lies in their physical dimensions and a unique display technology present in one. Both utilize similar display technology, offering clear visuals suitable for general use.

• Display Technology and Size: The iPhone 6S features a 4.7-inch Retina HD IPS LCD display, providing a larger viewing area, while the iPhone SE (2016) has a more compact 4.0-inch Retina IPS LCD display. Both offer a pixel density of 326 pixels per inch, resulting in sharp text and images.
• Brightness and Clarity: Both displays offer a typical maximum brightness of 500 cd/m2, ensuring adequate visibility in various indoor lighting conditions.
• Unique Feature: The iPhone 6S includes 3D Touch, a pressure-sensing technology that allows for new interactions based on how firmly the screen is pressed, a feature absent on the iPhone SE (2016).

Both the iPhone 6S and iPhone SE (2016) share a capable main camera system for their generation, delivering solid performance in good lighting. However, there are differences in their front-facing cameras and some specific features.

• Rear Camera System: Both devices are equipped with a 12-megapixel rear camera capable of recording 4K video at 30 frames per second, offering good detail for photos and videos. They also support Live Photos, capturing short video clips alongside still images.
• Front Camera Performance: The iPhone 6S features a 5-megapixel front-facing camera, which provides more detailed selfies and better video call quality compared to the iPhone SE (2016)'s 1.2-megapixel front camera. Both include Retina Flash, utilizing the display to illuminate selfies in low light.
• Video Capabilities: Beyond 4K recording, both phones offer slow-motion video at 1080p at 120 fps and 720p at 240 fps, along with cinematic video stabilization for smoother footage.
