Ratings

The Samsung Galaxy A33 5G (2022) and the Samsung Galaxy S21 5G (2021) represent two distinct tiers within the Samsung smartphone lineup, catering to different user priorities. While the Galaxy A33 5G is a mid-range device designed for longevity and everyday reliability, the Galaxy S21 5G was launched as a flagship model, prioritising high-end processing and advanced photography. Both devices run on the Android operating system with Samsung's One UI interface, ensuring a familiar software experience, though their hardware capabilities lead to different practical outcomes for the user.

Scores

Durability

The two devices offer different expectations for long-term use based on their release dates and build standards.

  • Software Longevity: The Galaxy A33 5G was released a year after the Galaxy S21 5G, which typically grants it an extra year of software updates. Users can expect the A33 to receive security patches slightly longer than the S21, making it a viable option for those seeking software longevity.
  • Physical Resilience: The Galaxy S21 5G features a higher water and dust resistance rating (IP68) compared to the Galaxy A33 5G (IP67). Both devices utilise reinforced glass on the front and plastic materials on the back, providing a balance between weight and resistance to cracks.
  • Repairability: Both models follow modern design trends with integrated batteries, resulting in moderate repairability scores. Professional technicians can replace screens and batteries, though the process requires specific tools to maintain the water-resistant seals.

Performance

Performance differences between these two models are most noticeable during intensive tasks and throughout a full day of heavy usage.

  • System Responsiveness: The Galaxy S21 5G is equipped with high-performance internal hardware that ensures smooth multitasking and rapid app switching. In contrast, the Galaxy A33 5G is designed for consistent everyday performance, handling social media and streaming efficiently, though it may show slight pauses under heavy load.
  • Battery Endurance: The Galaxy A33 5G houses a larger battery capacity than the S21 5G, which often results in longer usage times. Users who spend long days away from a power outlet will find the A33 more reliable for extended periods, whereas the S21 may require more frequent charging.
  • Storage and Memory: Both devices offer various storage configurations, typically starting at 128GB. The S21 generally includes more temporary memory (RAM), which assists in keeping more applications open in the background without needing to reload them.

Screen quality

The display experience differs in terms of smoothness and peak brightness, impacting how users consume media and interact with the interface.

  • Display Technology and Smoothness: The Galaxy S21 5G features a display with a 120Hz refresh rate, which makes scrolling through menus appear fluid. The Galaxy A33 5G offers a 90Hz refresh rate, which is smoother than standard screens but does not match the seamless feel of the flagship model.
  • Outdoor Visibility: While both devices use vibrant AMOLED technology, the Galaxy S21 5G can reach higher peak brightness levels. This makes the screen easier to read under bright sunlight compared to the Galaxy A33 5G, which remains clear but may require more shading.
  • Viewing Experience: The Galaxy A33 5G provides a slightly larger 16.2-centimetre (6.4-inch) screen area, beneficial for watching videos. The S21 5G is more compact at 15.7-centimetres (6.2-inches), making it easier to navigate with one hand while maintaining high resolution.

Audiovisual

Camera capabilities and media playback are areas where the flagship heritage of the S21 5G becomes most apparent.

  • Photography Versatility: The Galaxy S21 5G includes a dedicated telephoto lens, allowing users to capture clear photos from a distance with optical-quality zoom. The Galaxy A33 5G relies on a high-resolution main sensor and a macro lens for close-up shots, which is useful for different photography styles but lacks long-range clarity.
  • Video and Low Light: For video enthusiasts, the Galaxy S21 5G supports higher resolution recording and better stabilisation, resulting in consistent footage. It also performs more reliably in low-light environments, capturing more detail in evening photos compared to the A33 5G.
  • Audio Output: Both smartphones feature stereo speakers that provide a clear and balanced sound. The microphones on both devices are well-suited for clear voice calls, though the S21 5G offers more advanced software processing to reduce background noise during video capture.

Miscellaneous

Practical handling and connectivity features play a significant role in the daily user experience of these two smartphones.

  • Biometric Security: The Galaxy S21 5G utilises an ultrasonic fingerprint sensor located under the display, which is fast and reliable even if fingers are slightly damp. The Galaxy A33 5G uses an optical sensor, which is also integrated into the screen but may be slightly slower to register.
  • Connectivity and Ports: Both devices support 5G connectivity for fast mobile data and use a USB-C port for charging. Neither device includes a traditional headphone jack, so users will need to use wireless headphones or a compatible adapter for wired audio.
  • Physical Handling: The Galaxy S21 5G is noticeably lighter and narrower, making it a preferred choice for users who value portability. The Galaxy A33 5G is larger and heavier, which accommodates its bigger screen and battery but may feel more substantial in a pocket.

User feedback from various online communities highlights the distinct strengths of each device. The Galaxy S21 5G is frequently praised for its compact form factor and its ability to handle intensive applications without lag, though some users note that the battery life can be shorter during busy days. On the other hand, the Galaxy A33 5G receives positive remarks for its battery endurance and the value of its long-term software support, while some users mention that the camera performance in dark settings is less consistent.

Choosing between these two models depends largely on individual needs. Users who prioritise a high-performance camera, a smooth screen, and a compact design will find the Galaxy S21 5G to be a well-suited choice for their lifestyle. Conversely, those who value a larger display, extended battery life for long commutes, and a longer window of software updates may prefer the Galaxy A33 5G. For those looking to make a sustainable choice, the Galaxy S21 5G remains a powerful option when purchased as a quality-assured refurbished option. Both devices offer a robust Samsung experience, and selecting a refurbished model allows users to access these features while supporting a more circular economy. Ultimately, the decision rests on whether one values flagship-tier photography and speed or mid-range reliability and battery longevity.
