Ratings

The iPhone 12 (2020) and the iPhone 15 Pro Max (2023) represent two distinct generations of Apple's smartphone evolution. While the iPhone 12 introduced the modern flat-edge design and 5G connectivity to the standard lineup, the iPhone 15 Pro Max pushes the boundaries of mobile technology with a larger display, advanced materials, and a more versatile camera system. Both devices run the latest iOS software, but the three-year gap between their release dates results in significant differences in processing power, physical dimensions, and charging standards. This comparison explores how these differences impact daily usage for different types of users.

Scores

Durability

The age difference between these two models significantly impacts their expected software support and physical longevity in a modern ecosystem.

  • Software Support: The iPhone 12, launched in 2020, is closer to the end of its official update cycle, whereas the iPhone 15 Pro Max is expected to receive the latest software features and security patches for several more years, ensuring better future readiness.
  • Build Materials: The iPhone 15 Pro Max features a titanium frame, which offers a high strength-to-weight ratio and excellent resistance to daily wear, while the iPhone 12 uses a traditional aluminum frame and Ceramic Shield glass for screen protection.
  • Repairability: Both devices are designed with internal structures that allow for screen and battery replacements, though the newer model's internal layout has been updated to facilitate easier access for technicians, potentially extending its practical lifespan.

Performance

While both phones handle daily tasks with ease, the iPhone 15 Pro Max is built for more demanding workloads and intensive multitasking scenarios.

  • System Responsiveness: The iPhone 15 Pro Max handles high-end gaming and professional video editing apps with greater fluidity, whereas the iPhone 12 remains snappy for social media, web browsing, and standard productivity tasks.
  • Battery Endurance: Due to its larger physical size, the iPhone 15 Pro Max houses a significantly larger battery, providing much longer runtimes between charges compared to the more compact iPhone 12, which may require a midday top-up for heavy users.
  • Storage and Multitasking: With higher base storage options and more internal memory, the iPhone 15 Pro Max can keep more apps open in the background without needing to refresh them, making it better suited for power users who juggle multiple demanding applications.

Screen quality

The viewing experience differs greatly between these models, primarily due to advancements in display technology and physical screen real estate.

  • Display Smoothness: The iPhone 15 Pro Max features a high refresh rate display, making scrolling through feeds and system animations appear much smoother than the standard 60Hz screen found on the iPhone 12.
  • Outdoor Visibility: The newer model can reach much higher brightness levels, making the screen significantly easier to read under direct sunlight or in bright outdoor environments compared to the more modest peak brightness of the iPhone 12.
  • Screen Real Estate: The 6.7-inch display of the iPhone 15 Pro Max offers a more immersive experience for watching videos or reading long documents, while the 6.1-inch iPhone 12 is more manageable for users who prefer one-handed operation.

Audiovisual

The camera systems represent one of the most substantial leaps between these two generations, catering to different levels of photography and videography needs.

  • Zoom Capabilities: The iPhone 15 Pro Max includes a dedicated telephoto lens with 5x optical zoom, allowing for clear close-ups from a distance, a feature entirely absent on the dual-camera system of the iPhone 12.
  • Detail and Resolution: With a much higher resolution main sensor, the iPhone 15 Pro Max captures significantly more detail in photos, which is particularly noticeable when cropping into images or printing them in larger formats.
  • Low-Light Performance: Improvements in sensor size and image processing allow the iPhone 15 Pro Max to capture brighter, clearer photos in dark environments with less visual noise and better colour accuracy than the iPhone 12.

Miscellaneous

Practical differences in connectivity and physical design change how these devices integrate into your daily routine and existing accessory ecosystem.

  • Charging and Connectivity: The iPhone 15 Pro Max uses a universal USB-C port, allowing for faster data transfer and compatibility with standard cables, while the iPhone 12 relies on the older Lightning connector.
  • Physical Controls: The iPhone 15 Pro Max replaces the traditional mute switch with a customisable Action Button, which can be programmed to launch the camera, torch, or other shortcuts instantly.
  • Weight and Handling: The iPhone 12 is considerably lighter and smaller, making it easier to carry in a pocket, whereas the iPhone 15 Pro Max is a substantial device that offers a more premium feel but requires more effort to handle.

User feedback from various forums highlights the iPhone 12 as a reliable, straightforward device that still performs well for essential tasks, though some users note that its battery life shows its age during heavy use. In contrast, the iPhone 15 Pro Max receives consistent praise for its expansive screen and exceptional camera versatility, though its large size and weight can be a drawback for those with smaller hands or those who prefer portability.

Users who prefer a compact, lightweight phone for everyday communication, social media, and casual photography will find the iPhone 12 to be a practical and capable choice. On the other hand, those who prioritise professional-grade photography, long-lasting battery life, and the latest display technology for media consumption will likely lean toward the iPhone 15 Pro Max. Choosing a quality-assured refurbished option for either model is a sustainable choice that helps reduce electronic waste while providing a reliable device that has been thoroughly tested. Ultimately, the decision depends on whether you need a high-performance tool for creative work or a dependable daily companion for standard smartphone tasks. Both devices remain relevant in 2026, offering different balances of portability and power to suit diverse user profiles.
