Galaxy A23 5G Vs Galaxy S21 FE 5G

The Samsung Galaxy A23 5G, released in August 2022, and the Samsung Galaxy S21 FE 5G, launched in January 2022, are both Android smartphones from Samsung. While both offer 5G connectivity and run on the Android operating system, they cater to different user expectations, with the S21 FE 5G providing a more premium experience in display and performance, and the A23 5G focusing on core functionality and battery longevity.

When considering the long-term usability of these devices, their release timelines and software support policies are key factors.

• Release Timeline: The Galaxy S21 FE 5G was released earlier in January 2022, while the Galaxy A23 5G followed in August 2022. This difference in launch date impacts their respective software support cycles. [6, 11]
• Software Longevity: The Galaxy A23 5G typically receives two major Android OS upgrades and four years of security updates from its release. [6, 24] The Galaxy S21 FE 5G, being part of a higher-tier series, generally benefits from a longer support period, often receiving three major Android OS updates and four years of security updates. [21, 33] As of early 2026, the A23 5G has been updated to Android 15, while the S21 FE 5G is on Android 14. [13, 18, 36]
• Build and Durability: The Galaxy S21 FE 5G features Gorilla Glass Victus for screen protection and an IP68 rating for dust and water resistance, indicating a higher level of physical durability. [11, 35, 36] The Galaxy A23 5G uses Gorilla Glass 5 and lacks an official IP rating, suggesting it is less resistant to environmental elements. [4, 29]

The performance capabilities of these two smartphones vary significantly, influencing how smoothly they handle daily tasks and demanding applications.

• Processing Power: The Galaxy S21 FE 5G is equipped with a high-performance processor, enabling it to manage demanding applications, intensive multitasking, and graphic-heavy games with considerable fluidity. [11, 15, 20, 39] The Galaxy A23 5G features a processor that provides capable performance for everyday use, including browsing, social media, and lighter gaming, though it may show some slowdowns with more intensive tasks or extensive multitasking, particularly in variants with less RAM. [2, 29, 34]
• Storage and RAM: The Galaxy S21 FE 5G offers configurations with 6GB or 8GB of RAM and 128GB or 256GB of internal storage, without expandable storage. [11, 35] The Galaxy A23 5G comes with 4GB, 6GB, or 8GB of RAM and 64GB or 128GB of internal storage, with the added flexibility of a microSD card slot for storage expansion up to 1TB. [2, 6, 34]
• Battery Behavior: The Galaxy A23 5G houses a larger 5000mAh battery, which generally translates to extended usage times for many users. [1, 22] The Galaxy S21 FE 5G has a 4500mAh battery, which, combined with its more powerful components, typically provides a full day of moderate use but may require more frequent charging with heavy usage. [11, 23, 40]

The visual experience on these devices is a key differentiator, primarily due to their display technologies and features.

• Display Technology and Clarity: The Galaxy S21 FE 5G features a 6.4-inch Dynamic AMOLED 2X display, known for its vibrant colors, deep blacks, and excellent contrast. [11, 15, 26, 33] The Galaxy A23 5G has a larger 6.6-inch PLS LCD screen, which offers good clarity and color reproduction for its category, though it does not match the contrast levels of an AMOLED panel. [6, 10, 29, 34]
• Brightness and Refresh Rate: Both phones offer a 120Hz refresh rate for smoother scrolling and animations. [1, 15, 29, 33] The S21 FE 5G's display is capable of reaching higher peak brightness levels, making it more comfortable to view in bright outdoor conditions. [19] The A23 5G's brightness is suitable for most indoor and outdoor scenarios but may struggle in direct sunlight. [29]
• Viewing Experience: The S21 FE 5G's adaptive refresh rate and HDR10+ support contribute to a more immersive and responsive viewing experience, particularly for media consumption and gaming. [15, 35] The A23 5G provides a large screen area that is well-suited for general content viewing. [34]

Both smartphones offer versatile camera systems, but they differ in their capabilities for various photography and videography scenarios.

• Rear Camera System: The Galaxy S21 FE 5G features a triple camera setup with a 12MP main lens (with optical image stabilization), a 12MP ultrawide lens, and an 8MP telephoto lens offering 3x optical zoom. [3, 8, 33] This configuration provides flexibility for different shot types, including zoomed-in subjects. The Galaxy A23 5G has a quad-camera system, including a 50MP main sensor (with optical image stabilization), a 5MP ultrawide, a 2MP macro, and a 2MP depth sensor. [1, 6, 9]
• Photography Performance: The S21 FE 5G generally delivers strong image quality in good lighting conditions, with consistent color profiles across its main and ultrawide lenses. Its telephoto lens is effective for capturing distant details. [3, 32, 37] The A23 5G's 50MP main camera can capture detailed photos in well-lit environments, but its ultrawide and other auxiliary lenses may show limitations in detail and color consistency. [4, 5, 25] Both struggle more in low-light conditions, though the S21 FE 5G tends to perform better. [27, 32]
• Video Recording: The Galaxy S21 FE 5G supports 4K video recording at 60 frames per second from both its front and rear cameras, offering higher resolution and smoother footage. [3, 8, 26] The Galaxy A23 5G records video at up to 1080p at 30 frames per second, which is suitable for casual use but less capable for high-quality video capture. [5, 9]
