Galaxy S21 5G vs Galaxy S22 5G

The Samsung Galaxy S21 5G, released in January 2021, and the Samsung Galaxy S22 5G, launched in February 2022, represent two consecutive generations of Samsung's flagship smartphone line. Both devices offer a premium Android experience with Samsung's One UI, providing a consistent software experience with access to a vast ecosystem of applications. The S22 introduces refinements in camera technology and a more compact design, while the S21 offers a larger battery capacity.

When considering the long-term usability of these devices, their release timelines and software support are key factors. The Galaxy S21 5G, having been released earlier, has reached the end of its major Android OS updates as of February 2026, with security updates concluding after its fifth anniversary. The Galaxy S22 5G, being a year newer, is expected to receive major Android OS updates until 2025 and security updates until February 2027, offering a slightly longer period of official support.

• Software Longevity: The Galaxy S22 5G benefits from an additional year of major Android OS updates and security patches compared to the Galaxy S21 5G, extending its functional lifespan for users who prioritize the latest software features and security.
• Repairability: The Galaxy S21 5G generally received higher repairability scores (7.5-8.2 out of 10) from some assessments, partly due to its plastic back on the base model which can make disassembly easier. In contrast, the Galaxy S22 5G received a lower repairability score (3 out of 10) from iFixit, citing strong adhesive use for the battery and display, making repairs more challenging.
• Build Materials: The Galaxy S21 features a 'Glasstic' (plastic) back on its base model, while the Galaxy S22 upgrades to a glass back (Gorilla Glass Victus+) and an Armor Aluminum frame, contributing to a more premium feel. Both devices carry an IP68 rating for dust and water resistance.

Both the Galaxy S21 5G and Galaxy S22 5G deliver robust performance suitable for demanding applications and multitasking, though the newer model features an updated internal architecture. The choice between them often comes down to specific usage patterns and expectations for sustained high performance.

• Everyday Responsiveness: The Galaxy S21 5G, powered by its 5-nanometer processor, handles daily tasks, app launches, and general navigation smoothly. The Galaxy S22 5G features a newer generation processor, offering marginally better CPU performance, though this difference may not be significantly noticeable in typical daily use.
• Graphics Performance: For graphics-intensive tasks like gaming, the Galaxy S22 5G's newer processor provides a more substantial improvement, with up to 35% faster graphics performance and improved power efficiency compared to the S21's processor.
• Battery Behavior: The Galaxy S21 5G is equipped with a 4000 mAh battery, generally providing sufficient power for a full day of use for most users. The Galaxy S22 5G has a smaller 3700 mAh battery, which can result in shorter battery life, potentially requiring a charge before the end of a heavy usage day.

The display experience on both the Galaxy S21 5G and Galaxy S22 5G is vibrant and responsive, featuring Samsung's Dynamic AMOLED 2X technology. However, there are subtle differences in size and adaptive refresh rate capabilities.

• Display Technology and Clarity: Both phones feature Dynamic AMOLED 2X displays with HDR10+ support, offering rich colors, deep blacks, and excellent contrast. Both maintain a Full HD+ resolution, ensuring sharp visuals for everyday viewing.
• Brightness and Refresh Rate: Both devices achieve a peak brightness of 1300 nits, providing good visibility even in bright outdoor conditions. While both offer a 120Hz adaptive refresh rate for smooth scrolling and responsiveness, the Galaxy S22 5G can dynamically scale down to 10Hz, which can contribute to better power efficiency compared to the S21's minimum of 48Hz.
• Screen Size: The Galaxy S21 5G features a 6.2-inch display, offering a slightly larger viewing area. The Galaxy S22 5G has a marginally more compact 6.1-inch display, which contributes to its overall smaller footprint.

Both the Galaxy S21 5G and Galaxy S22 5G feature versatile triple-camera systems designed to capture a wide range of photos and videos. The S22 introduces an updated main sensor and improved low-light capabilities.

• Main Camera Performance: The Galaxy S21 5G features a 12MP main camera, which delivers good quality photos in various conditions. The Galaxy S22 5G upgrades to a 50MP main sensor, which, combined with improved processing, often results in more detailed images and enhanced low-light performance.
• Telephoto and Ultrawide: The S21 uses a 64MP telephoto lens with 3x hybrid zoom, while the S22 features a 10MP telephoto lens with 3x optical zoom, providing clearer zoomed-in shots due to true optical magnification. Both phones include a 12MP ultrawide camera, offering similar performance in capturing wider scenes.
• Video Recording and Audio: Both devices are capable of recording video at up to 8K resolution at 24fps and 4K at 30/60fps. The S22 often produces more detailed and smoother video recordings. Both phones feature stereo speakers for media consumption, but neither includes a 3.5mm headphone jack.
