Ratings

The Samsung Galaxy S21 Ultra 5G, launched in early 2021, and the iPhone 12 Pro Max, released in late 2020, represent the most advanced offerings from their respective manufacturers during that era. These smartphones were designed to provide the largest screens and most capable camera systems available to consumers at the time of their debut. While the Galaxy S21 Ultra operates on the Android platform with Samsung's custom interface, the iPhone 12 Pro Max runs Apple's iOS operating system. Both devices continue to be highly relevant for users seeking high-performance mobile technology today, offering distinct approaches to design and functionality.

Scores

Durability

The timeline for software support and physical resilience is a key factor when comparing these two flagship models, as both were built to last for several years of intensive use.

  • Software Longevity: The iPhone 12 Pro Max is expected to receive official software updates for a significant period, often reaching six or seven years from its original release date, ensuring access to new features.
  • Update Frequency: Samsung has committed to an extended update schedule for the Galaxy S21 Ultra, providing regular security patches and several major version upgrades to keep the interface modern and secure.
  • Physical Build: Both phones utilise high-quality glass and metal frames, though the iPhone's flat stainless steel edges offer a different grip and impact resistance compared to the Galaxy's curved aluminium and glass construction.

Performance

In daily use, both smartphones provide a responsive experience, though they handle multitasking and high-demand applications in different ways based on their internal optimisations.

  • System Responsiveness: The Galaxy S21 Ultra feels incredibly fluid when navigating through the interface, especially when using the split-screen feature to manage two applications at once without any noticeable slowdown.
  • App Performance: The iPhone 12 Pro Max is highly efficient at running demanding software, such as high-definition video editors or complex mobile games, maintaining consistent frame rates and stability.

Screen quality

The display is perhaps the most noticeable difference between these two devices, as they use different technologies to achieve visual clarity and motion smoothness.

  • Motion and Fluidity: The Galaxy S21 Ultra features a screen that can refresh its image twice as fast as the iPhone 12 Pro Max, resulting in much smoother scrolling through text and more lifelike animations.
  • Brightness and Outdoor Use: Both devices use advanced display technology for deep blacks and vibrant colours, but the Galaxy S21 Ultra can achieve higher peak brightness, which is helpful when viewing the screen in bright outdoor environments.
  • Viewing Experience: The iPhone 12 Pro Max offers a large, flat 6.7-inch viewing area that is excellent for watching movies, while the Galaxy S21 Ultra provides a slightly larger 6.8-inch screen with a higher pixel density for sharper text.

Miscellaneous

Beyond the main specifications, several practical features influence the daily handling and utility of these smartphones, from connectivity to unique input methods.

  • Connectivity and Ports: Both devices are compatible with 5G networks for high-speed internet, but they differ in their charging ports; the Galaxy uses the widely available USB-C standard, while the iPhone uses a proprietary connector.

Public sentiment from user forums and long-term reviews suggests that both the Galaxy S21 Ultra and the iPhone 12 Pro Max have aged gracefully. Galaxy users frequently highlight the versatility of the zoom camera and the smoothness of the high-refresh-rate screen as their favourite features. On the other hand, iPhone users often point to the reliability of the software ecosystem and the consistent quality of the video recording as the primary reasons they stay with the device. Some criticisms for the Galaxy include its large physical footprint, while some iPhone users mention the slower charging speeds compared to more recent standards.

When deciding between the two, the choice often comes down to specific user priorities. Users who prioritise a versatile camera with powerful zoom and a screen that feels exceptionally fluid will likely find the Galaxy S21 Ultra to be the better fit for their needs. Conversely, users who value a straightforward, reliable software experience and top-tier video performance may prefer the iPhone 12 Pro Max. For those interested in a sustainable choice, opting for a quality-assured refurbished version of either device is an excellent way to enjoy flagship features while being eco-friendly. Ultimately, both phones represent a high standard of mobile engineering that continues to deliver a premium experience. Choosing a refurbished model is a practical way to support a more circular economy without compromising on the technology required for modern life.
