Ratings

The Samsung Galaxy A54 (2023) and the Samsung Galaxy S21 5G (2021) represent two distinct paths within the Samsung smartphone ecosystem. While the Galaxy A54 is a modern mid-range device designed for longevity and endurance, the Galaxy S21 5G was originally released as a flagship model, offering premium features and high-end performance in a more compact form factor. Both devices operate on the Android platform with Samsung’s custom One UI interface, ensuring a familiar and customisable user experience across both models despite their different release years and original market positions.

Scores

Durability

The primary difference in longevity between these two devices stems from their respective release dates and Samsung's software support commitments for different product tiers.

  • Software Longevity: Because the Galaxy A54 was released in 2023, it benefits from a much longer future update cycle, with official software support expected to continue several years beyond that of the Galaxy S21.
  • Build Resilience: The Galaxy S21 features a metal frame that provides excellent structural rigidity, while the Galaxy A54 uses a glass front and back which, while modern and sleek, may require more careful handling to avoid cracks during accidental drops.
  • Repairability: Both devices are designed with standard internal layouts, making common repairs like screen or battery replacements straightforward for qualified technicians, though the A54's newer internal design is slightly more modular for certain components.

Performance

While the Galaxy S21 is the older of the two, its original flagship-grade internals allow it to maintain a high level of responsiveness that competes closely with newer mid-range models.

  • System Responsiveness: The Galaxy S21 excels at handling demanding applications and intensive multitasking without lag, whereas the Galaxy A54 is optimised for efficiency and smooth performance during everyday tasks like browsing, social media, and streaming.
  • Battery Endurance: The Galaxy A54 features a significantly larger battery capacity, which typically allows it to last through a full day of heavy use with plenty of charge remaining, comfortably outperforming the smaller battery found in the S21.
  • Storage Flexibility: Users who require large amounts of local storage for photos and offline media will appreciate the Galaxy A54's inclusion of a memory card slot, a practical feature that is absent on the Galaxy S21.

Screen quality

Both smartphones feature high-quality displays that offer smooth scrolling and vibrant colours, though they use slightly different technologies to achieve these visual results.

  • Display Technology: The Galaxy S21 utilises a more advanced screen type that can dynamically adjust its refresh rate to save power, while the Galaxy A54 offers a bright and clear panel that remains highly legible even in direct sunlight.
  • Viewing Experience: With a 6.4-inch screen, the Galaxy A54 provides a slightly larger canvas for watching videos and playing games compared to the more pocket-friendly 6.2-inch display of the Galaxy S21.
  • Visual Clarity: Both devices offer sharp resolutions that make text easy to read and images appear detailed, ensuring a high-quality experience for media consumption and general navigation through the interface.

The camera systems on these devices reflect their original design goals, with one focusing on modern sensor resolution and the other on versatile lens options for different scenarios.

  • Photography Versatility: The Galaxy S21 includes a dedicated telephoto lens that allows for clearer photos of distant subjects, a feature the Galaxy A54 lacks, as it relies instead on digital cropping for zoomed images.
  • Image Detail: In standard lighting, the Galaxy A54 captures very detailed images thanks to its high-resolution main sensor, making it a strong performer for everyday photography and social sharing.
  • Video and Audio: The Galaxy S21 supports higher-resolution video recording and features microphones that are particularly effective at isolating voices and reducing background noise during calls or recordings.

Miscellaneous

Beyond the core specifications, the physical design and connectivity options play a significant role in how these devices feel and function in daily use.

  • Portability and Handling: The Galaxy S21 is notably lighter and narrower, making it much easier to use with one hand, whereas the Galaxy A54 has a more substantial presence and weight that some users may find more secure.
  • Biometric Security: Both phones utilise under-display fingerprint sensors for secure access, providing a seamless and modern way to unlock the device and authorise secure payments.
  • Modern Connectivity: Each model supports 5G networks for fast mobile data, though the Galaxy A54 includes support for slightly newer Wi-Fi standards, which can improve connection stability on modern home routers.

User feedback from various online communities highlights distinct strengths for both devices. Owners of the Galaxy S21 frequently praise its compact size and the quality of its zoom camera, though some note that the battery requires more frequent charging as the device ages. Conversely, Galaxy A54 users often report high satisfaction with the exceptional battery life and the peace of mind provided by the extended software support. Some users have mentioned that the A54 feels slightly bulkier in the pocket compared to the sleek profile of the S series.

Choosing between these two depends largely on individual priorities. Users who prioritise a compact design, superior camera versatility, and a more premium feel will likely find the Galaxy S21 to be the better fit for their lifestyle. On the other hand, those who value long-term software updates, expandable storage, and a battery that can easily last a full day should lean toward the Galaxy A54. For those looking to make a sustainable choice, opting for a quality-assured refurbished option is an excellent way to get these features while reducing environmental impact. Ultimately, both smartphones offer a reliable experience, and choosing an eco-friendly alternative like a refurbished model ensures you receive a high-performing device that has been thoroughly tested for quality.
