Ratings

The Samsung Galaxy S21 5G, released in early 2021, and the Sony Xperia 1 IV, launched in mid-2022, represent two distinct philosophies in the Android smartphone market. While the Galaxy S21 focuses on providing a streamlined, user-friendly experience in a compact form factor, the Xperia 1 IV targets enthusiasts with its unique display and professional-grade camera features. Both devices operate on the Android platform, though they offer different software skins that change the visual interface and available customisation options for the user. These smartphones cater to different needs, from the casual social media user to the dedicated mobile photographer.

Scores

Durability

The Galaxy S21 5G arrived in 2021, making it the older of the two devices by over a year, which impacts its long-term software outlook. In terms of software longevity, Samsung has historically provided four years of major operating system updates and five years of security patches. By 2026, the S21 is approaching the end of its official support window, which may influence users looking for a device to last several more years. In contrast, the Sony Xperia 1 IV was released in 2022. While it is newer, Sony typically offers a shorter support cycle, often providing two to three years of major updates. This means both phones may find themselves on similar footing regarding software relevance in the current year.

  • Software Support: The Galaxy S21 benefits from a more predictable update schedule, whereas the Xperia 1 IV may stop receiving major Android versions sooner despite its later release date.
  • Physical Resilience: The S21 features a reinforced polycarbonate back that resists cracks from drops, while the Xperia 1 IV uses glass on both sides, offering a different tactile feel but requiring more care.
  • Repair Accessibility: Finding replacement parts and qualified technicians is generally more straightforward for the Galaxy S21 due to its higher market presence compared to the more specialised Sony model.

Performance

The Galaxy S21 5G and Sony Xperia 1 IV handle modern applications with ease, though they cater to different levels of multitasking intensity and power requirements. Both devices ensure that everyday tasks like browsing, messaging, and streaming remain fluid and responsive for the average user.

  • Multitasking and Memory: With a higher amount of internal memory, the Xperia 1 IV is better equipped to keep multiple demanding apps open in the background without refreshing, whereas the S21 may close background tasks more frequently during heavy use.
  • Battery Endurance: The Xperia 1 IV houses a significantly larger battery capacity, which helps it sustain a full day of use even with its high-resolution screen, while the S21's smaller physical size limits its battery life for power users.
  • Daily Responsiveness: Both devices provide a fluid experience when scrolling through social media or browsing the web, but the Xperia 1 IV maintains its speed more effectively during intensive tasks like high-definition video editing.

Screen quality

The display is perhaps the most significant point of divergence between these two smartphones, affecting everything from ergonomics to media consumption. While both offer high refresh rates for smooth motion, the visual presentation differs greatly in shape and clarity.

  • Display Technology and Shape: The Xperia 1 IV features a unique 21:9 aspect ratio, making it taller and narrower than the S21, which is ideal for watching cinematic films without black bars.
  • Resolution and Detail: Sony provides a 4K resolution display, offering incredible sharpness for close-up viewing, while the S21 uses a standard high-definition panel that is more than adequate for everyday tasks and helps preserve battery life.
  • Outdoor Visibility: The Galaxy S21 is known for its high peak brightness, making the screen easy to read even under direct sunlight, whereas the Xperia 1 IV prioritises colour accuracy and a natural look for creative professionals.

Both manufacturers have taken different approaches to photography and sound, with Sony leaning into professional tools and Samsung focusing on accessibility and ease of use. This makes the choice between them a matter of how much control the user wants over their media.

  • Camera Versatility: The Xperia 1 IV stands out with its continuous optical zoom lens, allowing for smooth transitions between focal lengths without losing detail, while the S21 relies on a high-resolution sensor to crop into images for its zoom effect.
  • User Interface: Samsung’s camera software is designed for quick, automated results that look great instantly, whereas Sony provides manual controls that mimic professional cameras, requiring more input from the user to get the best results.
  • Audio Experience: The Xperia 1 IV includes a traditional headphone jack and front-facing stereo speakers, making it a preferred choice for those who use wired audio equipment or watch videos without headphones.

Miscellaneous

Practical features and physical dimensions often dictate how a phone fits into a user's daily routine, especially regarding connectivity and storage. These small differences can have a large impact on the overall convenience of the device.

  • Expandable Storage: The Xperia 1 IV includes a microSD card slot, allowing users to easily increase their storage space for photos and videos, a feature that is absent on the Galaxy S21.
  • Biometric Security: The S21 uses an ultrasonic fingerprint sensor hidden under the display for quick access, while the Xperia 1 IV integrates its fingerprint scanner into the power button on the side of the frame.
  • Portability and Handling: Because of its smaller screen and lighter materials, the Galaxy S21 is much easier to use with one hand, whereas the Xperia 1 IV’s tall design may require two hands for certain tasks but offers more screen real estate.

User feedback from various community forums highlights the distinct reputations of these two devices. The Samsung Galaxy S21 5G is frequently praised for its manageable size and the reliability of its software, with many users appreciating how it fits comfortably in a pocket while still delivering a flagship experience. However, some users have noted that the plastic back, while durable, doesn't feel the same as glass, and the lack of expandable storage is a common point of contention. On the other hand, the Sony Xperia 1 IV receives high marks from enthusiasts for its "no-compromise" approach to features like the headphone jack and the stunning 4K display. The primary criticism directed at the Sony model involves its tendency to become warm during long video recording sessions or intensive gaming.

Choosing between these two depends heavily on individual priorities. Users who want a compact, reliable device for everyday communication and social media will likely find the Galaxy S21 5G fits their lifestyle perfectly. Conversely, those who prioritise media creation, cinematic viewing, and professional-grade camera controls will lean toward the Sony Xperia 1 IV. Choosing a quality-assured refurbished option allows users to access these high-end features while supporting a more circular economy. Ultimately, both phones remain capable choices in 2026, with the S21 serving as a practical daily companion and the Xperia 1 IV acting as a specialised tool for creators, making it a more sustainable choice for the environmentally conscious consumer.
