Ratings

The Samsung Galaxy S21 Ultra 5G and the iPhone 13, both released in 2021, represent two distinct philosophies in the smartphone market. While the Galaxy S21 Ultra 5G serves as a feature-rich, large-format device designed for power users, the iPhone 13 offers a more compact and streamlined experience. The primary difference lies in their operating systems, with Samsung utilising the flexible Android platform and Apple employing its proprietary iOS ecosystem. These devices cater to different priorities, from advanced photography to long-term software reliability.

Scores

Durability

The Galaxy S21 Ultra 5G and iPhone 13 differ significantly in their expected software lifespans and physical resilience.

  • Software Longevity: The iPhone 13 generally benefits from Apple's extended support cycle, often receiving major updates for six to seven years, whereas the Galaxy S21 Ultra 5G follows a structured four-year OS update policy. By 2026, the iPhone remains more current with the latest operating system features and security patches.
  • Build and Repairability: Both devices feature glass and metal constructions that require careful handling, though the iPhone 13's flat-edge design and specialised glass are noted for their impact resistance. The Samsung model's curved screen can be more complex to repair if damaged.
  • Practical Lifespan: Users can expect both phones to remain functional for several years, but the iPhone 13 is likely to remain compatible with the latest applications for a longer period due to its later release and software commitment.

Performance

While both devices handle modern applications with ease, they manage resources and battery life in different ways.

  • Multitasking and Memory: The Galaxy S21 Ultra 5G is equipped with a high amount of temporary memory, allowing it to keep numerous demanding apps open simultaneously without slowing down. This makes it well-suited for users who switch between heavy tasks frequently.
  • Battery Endurance: With a significantly larger battery capacity, the Galaxy S21 Ultra 5G is better suited for users who spend long days away from a charger, while the iPhone 13 relies on software efficiency to provide a full day of standard use.
  • System Responsiveness: The iPhone 13 is frequently praised for its consistent smoothness during navigation and app launches, whereas the Galaxy S21 Ultra 5G offers a highly responsive experience that excels in productivity-heavy tasks and mobile gaming.

Screen quality

The viewing experience is one of the most noticeable differences between these two 2021 flagships.

  • Display Technology and Smoothness: The Galaxy S21 Ultra 5G features a high refresh rate that makes scrolling and animations appear exceptionally fluid, a feature absent on the standard iPhone 13, which uses a standard refresh rate.
  • Size and Clarity: Users who enjoy watching videos or reading will appreciate the Galaxy S21 Ultra 5G's expansive 6.8-inch screen and high pixel density, while the iPhone 13's 6.1-inch display offers a more manageable size for one-handed use and pocketability.
  • Outdoor Visibility: Both screens use advanced light-emitting diode technology to produce vibrant colours and deep blacks, ensuring they remain legible even under direct sunlight, though the Samsung model can reach higher peak brightness levels in extreme conditions.

Audiovisual

Photography and media consumption are handled with different hardware configurations on each model.

  • Zoom and Versatility: The Galaxy S21 Ultra 5G includes a sophisticated multi-lens system that allows for a high level of detail when photographing distant objects, a capability the dual-lens iPhone 13 cannot match with its more basic setup.
  • Video and Colour Accuracy: The iPhone 13 is often preferred for video recording due to its natural colour reproduction and widely recognised stabilisation features that make handheld filming look professional and steady.
  • Audio Experience: Both devices provide clear, loud stereo sound, though the larger frame of the Galaxy S21 Ultra 5G allows for a slightly more immersive audio stage during media playback and video calls.

Miscellaneous

Beyond the core specs, the physical design and connectivity options influence daily convenience.

  • Biometrics and Security: The iPhone 13 utilises facial recognition for secure unlocking, while the Galaxy S21 Ultra 5G uses an ultrasonic fingerprint sensor located beneath the glass of the display for quick access.
  • Connectivity and Ports: The Galaxy S21 Ultra 5G uses the universal USB-C standard for charging and data, whereas the iPhone 13 uses the proprietary Lightning port, which may require specific cables for those moving from other brands.
  • Handling and Weight: The iPhone 13 is considerably lighter and easier to pocket, making it a better fit for travellers, while the Galaxy S21 Ultra 5G's weight reflects its more substantial build and larger internal components.

According to user discussions on various tech forums, the Galaxy S21 Ultra 5G is frequently lauded for its versatile camera system and the clarity of its large display. Many users appreciate the ability to use a stylus for note-taking, though some find the device's size cumbersome for daily carry. Conversely, the iPhone 13 receives praise for its reliable software performance and the simplicity of its user interface. A common point of discussion among owners is the iPhone's consistent video quality and its ability to remain functional over time through regular updates. Some users do note the lack of a high refresh rate on the iPhone 13 as a point of comparison with other flagship models.

Users prioritising a large screen for media consumption and advanced photography features may find the Galaxy S21 Ultra 5G aligns best with their needs. Meanwhile, those who prefer a compact, easy-to-use smartphone with a long software support window might lean toward the iPhone 13. Choosing a quality-assured refurbished option for either of these models allows consumers to access advanced technology while making a sustainable choice. Both devices remain highly capable in 2026, offering a balance of modern features and reliable build quality for different types of mobile users.
