Ratings

The Samsung Galaxy A25 (2023) and the Samsung Galaxy S21 5G (2021) represent two different approaches to the smartphone experience. While the Galaxy A25 is a contemporary mid-range device designed for longevity and essential features, the Galaxy S21 5G was originally a flagship model, offering high-end capabilities that remain relevant today. Both devices operate on the Android ecosystem, but they differ significantly in their release timing and intended user base.

The Galaxy A25 focuses on modern software support and battery life, whereas the Galaxy S21 5G prioritises a compact form factor and advanced camera hardware. This comparison explores how these two generations of Samsung technology serve different user priorities in the current landscape.

Scores

Durability

The Galaxy A25 and Galaxy S21 5G offer different perspectives on longevity, influenced by their respective release dates and manufacturer support cycles.

  • Software Longevity: The Galaxy A25, released in late 2023, benefits from a much newer starting point for its operating system updates, meaning it will likely receive security patches and software features for several years longer than the S21.
  • Physical Resilience: While the Galaxy S21 5G features a metal frame and high-strength glass, the Galaxy A25 utilises a sturdy plastic construction that is less prone to shattering if dropped, though it lacks the official water resistance rating found on the older flagship.
  • Sustainable Lifecycle: Choosing a quality-assured refurbished option for either device helps extend the functional life of existing hardware, making it a more eco-friendly alternative to purchasing brand-new electronics.

Performance

Daily responsiveness and multitasking capabilities vary between these two models due to their different internal architectures and battery capacities.

  • System Responsiveness: The Galaxy S21 5G, despite its age, contains high-performance internals that allow it to handle demanding tasks like video editing or high-end gaming with greater ease than the more modest components found in the A25.
  • Battery Endurance: Users will find that the Galaxy A25 offers significantly longer runtimes between charges, as it houses a much larger physical battery and a processor designed for energy efficiency rather than raw power.
  • Storage Flexibility: The Galaxy A25 includes a slot for memory expansion, allowing users to add more space for photos and files, a feature that is absent on the Galaxy S21 5G which relies solely on its built-in internal storage.

Screen quality

Both smartphones utilise vibrant display technology, but they differ in size, brightness, and the overall smoothness of the visual experience.

  • Display Technology: The Galaxy S21 5G features a more advanced screen that can adjust its refresh rate dynamically to save power, while also reaching higher peak brightness levels which makes it easier to read under direct sunlight.
  • Viewing Area: The Galaxy A25 provides a larger canvas for watching videos or reading text, which may appeal to users who prefer a more immersive experience, even if the surrounding borders are slightly more noticeable than those on the S21.
  • Visual Fluidity: Both devices support a high refresh rate, ensuring that scrolling through social media feeds or navigating menus feels fluid and responsive to the touch.

Audiovisual

The camera systems on these devices are tailored for different types of photography, with the older flagship still holding an edge in versatility.

  • Zoom and Versatility: The Galaxy S21 5G includes a dedicated lens for zooming into distant subjects without losing significant detail, a feature the Galaxy A25 lacks, as it relies on digital cropping for closer shots.
  • Video Capabilities: For those who record a lot of footage, the Galaxy S21 5G offers higher resolution options and more advanced stabilisation, resulting in smoother videos when walking or moving the camera.
  • Everyday Photography: In bright daylight, both phones produce clear and colourful images suitable for social media, though the Galaxy S21 5G generally handles difficult lighting conditions and night-time shots with more balance and less visual noise.

Miscellaneous

Practical features like physical ports and biometric security play a significant role in how these devices integrate into a user's daily routine.

  • Physical Connectivity: The Galaxy A25 retains a traditional headphone jack, allowing for the use of wired audio without adapters, whereas the Galaxy S21 5G requires wireless headphones or a converter for its charging port.
  • Biometric Security: The Galaxy S21 5G uses a sensor hidden beneath the glass for fingerprint recognition, while the Galaxy A25 integrates its sensor into the power button on the side, which some users find more intuitive to reach.
  • Portability and Handling: The Galaxy S21 5G is noticeably more compact and lighter, making it easier to use with one hand, while the Galaxy A25 is larger and heavier, requiring a more deliberate grip.

User feedback from various online communities suggests that the Galaxy S21 5G remains a favourite for those who value a compact design and a high-quality camera system. Many users praise its snappy performance even years after its launch, though some express concerns about the battery life not lasting through a full day of heavy use. Conversely, the Galaxy A25 is frequently highlighted for its impressive battery endurance and the inclusion of a microSD slot, which provides peace of mind for those with large media libraries. Some users note that the A25 can feel slightly slower when switching between many open apps compared to flagship models.

When deciding between these two, users who prioritise long-term software support, expandable storage, and a battery that can easily clear a full day will find the Galaxy A25 to be a practical choice. On the other hand, users who prefer a smaller device that takes better photos and handles intensive tasks with more fluidity may lean toward the Galaxy S21 5G. Both devices are available as eco-friendly, quality-assured refurbished options, allowing consumers to access reliable technology while reducing electronic waste. Ultimately, the choice depends on whether one values the modern efficiency and longevity of a newer mid-range device or the refined features and power of an older flagship.
