Ratings

The Samsung Galaxy S21 5G, released in early 2021, and the Sony Xperia 5 IV, launched in late 2022, represent two distinct approaches to the compact smartphone market. While the Galaxy S21 focuses on providing a streamlined, mainstream experience with a flat display and a robust software ecosystem, the Xperia 5 IV targets multimedia enthusiasts with its unique tall aspect ratio and professional-grade camera tools. Both devices run on the Android operating system, though they offer distinct user interfaces that influence how you manage notifications, customisation, and navigation.

Scores

Durability

The Galaxy S21 and Xperia 5 IV offer different expectations regarding software longevity and physical resilience based on their release dates and manufacturer policies.

  • Software Longevity: The Galaxy S21 was released earlier but benefited from an industry-standard update policy that provided several years of operating system and security patches. By 2026, it is approaching the end of its major update cycle. The Xperia 5 IV, being a year newer, launched with a more recent version of Android, though its manufacturer typically provides a shorter window of major software support compared to Samsung.
  • Repairability and Build: The Galaxy S21 features a reinforced polycarbonate back that is highly resistant to cracking, while the Xperia 5 IV uses glass on both sides for a traditional aesthetic. Replacement parts for the Galaxy series are generally more accessible at independent repair shops, which can help extend the device's practical lifespan.
  • Environmental Impact: Choosing a quality-assured refurbished option for either of these models is an effective way to help reduce electronic waste.

Performance

Both smartphones deliver a responsive experience for everyday tasks, though their internal designs lead to different outcomes for battery endurance and storage flexibility.

  • Multitasking and Speed: Both devices handle demanding applications and frequent task-switching with ease, ensuring smooth daily use. The Galaxy S21 is well-regarded for its consistent system stability, while the Xperia 5 IV maintains high performance during intensive multimedia tasks thanks to its current-generation processor.
  • Battery Life: The Xperia 5 IV contains a significantly larger battery capacity relative to its compact size. In real-world usage, this provides more headroom for users who spend long periods away from a power source, whereas the Galaxy S21 may require more frequent charging for those with high screen-on time.
  • Storage Flexibility: While the Galaxy S21 relies entirely on its internal storage capacity, the Xperia 5 IV includes a physical slot for memory expansion. This allows users to increase their available space for high-resolution photos and videos without needing to rely on cloud-based subscription services.

Screen quality

The viewing experience on these two devices is defined by their contrasting physical dimensions and display technologies.

  • Display Shape and Utility: The Xperia 5 IV features a distinct 21:9 aspect ratio, making it taller and narrower than the Galaxy S21. This design is particularly well-suited for watching cinematic films without black bars and allows for more vertical content when scrolling through social feeds. The Galaxy S21 uses a more traditional 20:9 ratio that feels familiar to most users.
  • Visual Fluidity: Both screens offer high refresh rates, ensuring that animations and scrolling appear smooth and fluid. The Galaxy S21's display is known for its high peak brightness, which improves legibility when used under direct sunlight during outdoor activities.
  • Clarity and Colour: Each device utilises OLED technology, providing deep blacks and high contrast. The Xperia 5 IV avoids any screen cutouts for the front camera by placing it in a slim top bezel, offering an uninterrupted view for gaming and media consumption.

Photography and video capabilities are a major point of difference, with one device focusing on automation and the other on manual creative control.

  • Everyday Photography: The Galaxy S21 is designed for efficient photography, using intelligent software to automatically adjust colours and lighting for a vibrant look. Its high-resolution secondary sensor allows for clear zoomed-in shots of distant subjects.
  • Creative Control: The Xperia 5 IV is designed for users who prefer a more natural look and precise manual adjustments. It includes dedicated applications that mimic the interface of professional cameras, allowing for control over focus and exposure. It also features a physical shutter button for a tactile photography experience.
  • Video and Audio: Both devices record high-quality video, but the Xperia 5 IV prioritises audio fidelity with advanced microphone settings and a focus on natural sound reproduction. The Galaxy S21 offers excellent software-based stabilisation, which is helpful for capturing steady footage while on the move.

Miscellaneous

Beyond the core specifications, the physical handling and connectivity options define the daily user experience for these two smartphones.

  • Physical Handling: The Xperia 5 IV is exceptionally narrow, making it very easy to grip with one hand, though its height might require some adjustment when reaching for the top of the screen. The Galaxy S21 is slightly wider but shorter, offering a balanced feel that fits comfortably in most pockets and hands.
  • Connectivity and Ports: A significant differentiator is the inclusion of a 3.5mm headphone jack on the Xperia 5 IV, allowing for the use of wired headphones without an adapter. The Galaxy S21 relies on the USB-C port or wireless Bluetooth connections for all audio output.
  • Security Features: The Galaxy S21 uses an ultrasonic fingerprint sensor located under the display glass, which remains responsive for quick access. The Xperia 5 IV places its fingerprint sensor on the side-mounted power button, which many users find intuitive for unlocking the device as they pick it up.

User feedback on community forums often highlights the Galaxy S21 for its reliability and the polished nature of its software interface. Many owners appreciate the flat screen and the consistent performance of the camera in various lighting conditions. However, some long-term users note that the battery life can be a limiting factor during days of heavy usage. Conversely, the Sony Xperia 5 IV is frequently praised for its impressive battery longevity and the inclusion of enthusiast features like the headphone jack and expandable storage. Some criticisms of the Sony device focus on its tendency to become warm during intensive video recording and the steeper learning curve of its professional camera applications.

Users who prioritise a straightforward, reliable smartphone with long-term software support and a bright, easy-to-read screen will likely find the Galaxy S21 5G to be a suitable choice for daily use. It offers a balanced experience that fits well into a standard mobile ecosystem. On the other hand, users who value high-quality audio through wired connections, extensive battery life, and manual control over their photography may prefer the Sony Xperia 5 IV. Its unique dimensions and specialised features cater to those with specific creative or technical requirements. Choosing an eco-friendly alternative like a quality-assured refurbished device is a practical way to access these features while supporting a more sustainable electronics cycle.
