iPhone 12 • Unlocked vs iPhone 14 • Locked AT&T

The iPhone 12, released in October 2020, and the iPhone 14, launched in September 2022, represent different generations within Apple's smartphone lineup. While both devices offer a consistent iOS experience, the iPhone 14 introduces advancements in camera technology, internal design, and safety features. This comparison will explore the practical differences between these two models to help users make an informed decision, considering that both are available as quality-assured refurbished options.

When considering the longevity of these devices, their release timelines and software support are key factors. The iPhone 14, being a newer model, generally offers a longer period of software updates and security patches compared to the iPhone 12.

• Release Timeline: The iPhone 12 was introduced in October 2020, while the iPhone 14 followed almost two years later in September 2022. This difference in release date directly impacts the duration of future iOS support, with the iPhone 14 expected to receive updates for a longer period.
• Software Longevity: Users can anticipate the iPhone 14 to maintain software compatibility and receive new features for at least an additional year or two beyond the iPhone 12, extending its practical lifespan for those who prioritize the latest software experience.
• Repairability: The iPhone 12 received an initial repairability score of 6 out of 10 from iFixit, indicating that many parts could be replaced. However, the iPhone 14 initially received a higher score due to an internal redesign that made it easier to access components like the back glass. This initial positive assessment for the iPhone 14 was later revised to a lower score of 4 out of 10 by iFixit, due to software limitations and part-pairing procedures that complicate unauthorized repairs.

Both the iPhone 12 and iPhone 14 deliver capable performance for everyday tasks, but the newer model benefits from a more advanced internal architecture, leading to smoother operation in demanding scenarios.

• Overall Responsiveness: The iPhone 14 features a more efficient processor, which translates to slightly faster app loading times and a more fluid user experience, especially when navigating between multiple applications.
• Multitasking and Demanding Apps: While both devices handle multitasking well, the iPhone 14's enhanced processing power and increased RAM allow it to manage more intensive applications and complex tasks with greater ease, reducing potential slowdowns during heavy usage.
• Battery Behavior: The iPhone 14 generally offers improved battery life compared to the iPhone 12, providing more usage time on a single charge. The iPhone 12's battery life was noted to be impacted by 5G usage, lasting around 8 hours and 25 minutes on a 5G network in some tests, while the iPhone 14 typically lasts longer, with some tests showing around 9 hours and 28 minutes.

Both smartphones feature high-quality displays, offering vibrant visuals, but the iPhone 14 includes minor enhancements that contribute to a slightly improved viewing experience.

• Display Technology and Clarity: Both the iPhone 12 and iPhone 14 utilize a 6.1-inch Super Retina XDR OLED display, providing deep blacks, excellent contrast, and sharp 2532 x 1170 pixel resolution at approximately 460 pixels per inch.
• Brightness Levels: The iPhone 14 offers a slightly higher typical maximum brightness of 800 nits compared to the iPhone 12's 625 nits, making content a bit more visible in bright outdoor conditions, though both reach a peak brightness of 1200 nits for HDR content.
• Refresh Rate: Both models maintain a standard 60Hz refresh rate, which provides a smooth experience for most users. However, neither device offers the higher refresh rates found in some other smartphones, which can provide an even smoother scrolling and gaming experience.

The camera systems on both the iPhone 12 and iPhone 14 are capable of capturing high-quality photos and videos, but the iPhone 14 introduces several advancements for improved image processing and low-light performance.

• Photography Performance: The iPhone 14 features an upgraded main camera with a larger sensor and a wider aperture (f/1.5 compared to iPhone 12's f/1.6), allowing it to capture more light and produce better results in challenging lighting conditions. It also benefits from the Photonic Engine, which enhances mid-to-low light performance across all cameras.
• Video Recording Capabilities: Both phones support 4K Dolby Vision HDR video recording. The iPhone 14 introduces Action mode for smoother video capture during movement and an improved Cinematic mode, offering more creative control over depth of field in videos.
• Front Camera and Audio: The iPhone 14's front-facing camera includes autofocus for clearer selfies and video calls, a feature not present on the iPhone 12. Both devices offer good microphone quality for calls and recordings, and deliver clear speaker output for media consumption.
