iPhone 12 vs iPhone 15 Pro

The iPhone 12, released in October 2020, and the iPhone 15 Pro, launched in September 2023, represent different generations within Apple's smartphone lineup. While both operate on the iOS platform, the iPhone 15 Pro introduces significant advancements in processing power, camera technology, display features, and design materials. This comparison aims to highlight the practical differences between these two devices to assist in making an informed decision.

The longevity of a smartphone is influenced by its physical durability and the duration of software support it receives.

• Release Timeline: The iPhone 12, released in October 2020, is an older model compared to the iPhone 15 Pro, which debuted in September 2023. This age difference directly impacts their remaining software support lifespan.
• Software Support: The iPhone 12 is expected to receive major iOS updates until approximately 2027, with security updates potentially extending a bit further. The iPhone 15 Pro, being a much newer device, is anticipated to receive major software updates until at least 2028, and potentially up to 2030 or 2031, offering a longer period of access to new features and security enhancements.
• Physical Durability: Both models feature a Ceramic Shield front cover, which provides enhanced drop performance. The iPhone 12 has an aluminum frame, while the iPhone 15 Pro utilizes a more robust and lighter aerospace-grade titanium frame. Both devices carry an IP68 rating for water and dust resistance, allowing submersion up to 6 meters for 30 minutes. The iPhone 15 Pro also features a more repairable internal design.

Performance differences between these two models are notable, primarily due to the generational leap in internal components.

• Processing Power: The iPhone 12 is equipped with a capable processor that handles everyday applications and multitasking smoothly. For its time, it offered strong performance. The iPhone 15 Pro, however, features a significantly more advanced processor, delivering substantially faster CPU and GPU speeds. This translates to quicker app loading, smoother multitasking, and a more fluid experience with demanding applications and graphics-intensive games.
• Multitasking and Responsiveness: The iPhone 12 comes with 4GB of RAM, which is sufficient for typical daily use. The iPhone 15 Pro doubles this to 8GB of RAM, allowing for more applications to run simultaneously in the background without needing to reload, enhancing overall system responsiveness, especially for power users.
• Battery Behavior: The iPhone 12 generally offers average battery life, with heavy usage, particularly with 5G connectivity, often requiring a charge before the end of a full day. The iPhone 15 Pro provides improved battery endurance, typically lasting a full day even with medium to heavy usage, and performing better in web browsing tests compared to its immediate predecessor.

The visual experience on both devices is delivered through high-quality displays, though the iPhone 15 Pro introduces several enhancements.

• Display Technology and Size: Both the iPhone 12 and iPhone 15 Pro feature a 6.1-inch Super Retina XDR OLED display, offering deep blacks and vibrant colors.
• Resolution and Clarity: The iPhone 12 has a resolution of 2532x1170 pixels at 460 pixels per inch (ppi). The iPhone 15 Pro offers a slightly higher resolution of 2556x1179 pixels, maintaining a similar pixel density of 460 ppi, resulting in comparable sharpness for typical viewing distances.
• Brightness and Smoothness: The iPhone 12's display reaches a typical brightness of 625 nits and a peak HDR brightness of 1200 nits. The iPhone 15 Pro significantly increases these figures, offering 1000 nits typical brightness, 1600 nits peak HDR brightness, and an impressive 2000 nits peak brightness for outdoor use, making content more visible in bright sunlight. Additionally, the iPhone 15 Pro features a 120Hz ProMotion refresh rate, providing a noticeably smoother scrolling experience and more fluid animations compared to the iPhone 12's standard 60Hz refresh rate.
• Design Elements: The iPhone 12 features a traditional notch at the top of its display. The iPhone 15 Pro replaces this with the Dynamic Island, a pill-shaped cutout that intelligently adapts to display alerts and background activities, alongside thinner display bezels for a more expansive viewing area.

The camera systems on these two iPhones reflect a significant evolution in mobile photography and videography.

• Rear Camera System: The iPhone 12 features a dual 12MP camera setup, including a wide and an ultrawide lens, capable of capturing good quality photos and 4K video. The iPhone 15 Pro boasts a more advanced triple camera system, comprising a 48MP main sensor, a 12MP ultrawide lens, and a 12MP telephoto lens with 3x optical zoom. This allows for greater detail, improved low-light performance, and more versatile zoom capabilities.
• Photography Features: The iPhone 15 Pro offers substantial upgrades in computational photography, including enhanced Night mode, more advanced Portrait mode with focus and depth control, and the ability to capture 48MP HEIF images. It also supports features like Action mode for stabilized video and Cinematic mode for video with shallow depth of field, which are not present on the iPhone 12. The iPhone 15 Pro's larger main sensor contributes to better light gathering and overall image quality.
• Front Camera: Both devices include a 12MP front-facing camera. However, the iPhone 15 Pro's front camera has a wider aperture (f/1.9 compared to f/2.2 on the iPhone 12), which theoretically allows for better low-light selfies and improved depth sensing.
• Audio Experience: Both models provide stereo speaker output for media consumption. While the iPhone 12 offers clear audio, the iPhone 15 Pro benefits from newer audio processing technologies, potentially delivering a richer sound experience and improved microphone quality for calls and video recordings.
