Galaxy S21+ 5G vs Google Pixel 6a

The Samsung Galaxy S21 Plus 5G, released in January 2021, and the Google Pixel 6a, launched in July 2022, are both Android smartphones offering distinct user experiences. While the Galaxy S21 Plus 5G provides a larger display and a more comprehensive camera hardware setup, the Pixel 6a emphasizes Google's integrated software features and a more compact design.

The longevity and support for these devices vary, influenced by their release timelines and manufacturer update policies.

• Software Support: The Galaxy S21 Plus 5G, released in early 2021, received four major Android OS updates, with its final major OS update (Android 15) in May 2025 and security updates concluding in January 2026. The Google Pixel 6a, launched in mid-2022, was initially promised three years of OS updates and five years of security updates. This was later extended, with OS updates expected until at least July 2025 and security updates until at least July 2027.
• Physical Durability: The Galaxy S21 Plus 5G features an IP68 rating for water and dust resistance, along with Gorilla Glass Victus on both the front and back for enhanced protection. The Pixel 6a has an IP67 rating and uses Gorilla Glass 3 on its display, complemented by a durable plastic back.
• Repairability: The Pixel 6a generally offers a more straightforward repair experience, with a repairability score of 7 out of 10, partly due to its display being attached with clips and an easily removable battery. The Galaxy S21 Plus 5G, while having a modular design, can be more challenging to repair, particularly concerning battery removal and certain internal components.

Both devices deliver capable performance for daily tasks, though they approach processing power and memory management with different philosophies.

• Processing Capabilities: The Galaxy S21 Plus 5G is equipped with a processor designed for high-end performance, enabling smooth operation across demanding applications and graphically intensive games. Users may experience warmth during prolonged heavy use, which can occasionally lead to reduced performance. The Pixel 6a features a processor optimized for artificial intelligence and machine learning tasks, contributing to a fluid and responsive experience for everyday applications and Google's software features.
• Memory and Storage: The Galaxy S21 Plus 5G comes with 8GB of RAM and offers storage options of 128GB or 256GB. The Pixel 6a includes 6GB of RAM and 128GB of internal storage. The difference in RAM may be noticeable during extensive multitasking or when running many applications simultaneously, where the Galaxy S21 Plus 5G may offer a slight advantage.
• Battery Behavior: The Galaxy S21 Plus 5G houses a 4800 mAh battery, generally providing sufficient power for a full day of moderate use, though heavy usage, especially with 5G, can lead to more frequent charging. The Pixel 6a has a 4410 mAh battery, with Google touting up to 24 hours of typical use. Some Pixel 6a users have reported varying battery life experiences, with some noting the need for more frequent charging under heavy use.

The visual experience on these smartphones is a key differentiator, primarily due to variations in display technology and size.

• Display Technology and Size: The Galaxy S21 Plus 5G features a larger 6.7-inch Dynamic AMOLED 2X display, offering vibrant colors, deep blacks, and excellent contrast. The Pixel 6a has a more compact 6.1-inch OLED display, which also provides good color reproduction and contrast.
• Resolution and Clarity: Both devices share a similar 1080 x 2400 pixel resolution, ensuring sharp text and clear images for typical viewing distances.
• Refresh Rate and Brightness: A notable difference is the refresh rate; the Galaxy S21 Plus 5G offers a smoother 120Hz adaptive refresh rate, which enhances scrolling and animation fluidity. The Pixel 6a maintains a standard 60Hz refresh rate. In terms of brightness, the Galaxy S21 Plus 5G can reach up to 1300 nits peak brightness, providing better visibility in bright outdoor conditions compared to the Pixel 6a.

Both smartphones offer capable camera systems, but they excel in different areas of photography and videography.

• Rear Camera System: The Galaxy S21 Plus 5G features a versatile triple-camera setup, including a 12MP wide-angle lens, a 12MP ultra-wide lens, and a 64MP telephoto lens with 3x hybrid optical zoom. This configuration provides flexibility for various shooting scenarios. The Pixel 6a employs a dual-camera system with a 12.2MP main lens (with optical image stabilization) and a 12MP ultra-wide lens, relying heavily on computational photography for image enhancement.
• Photography Performance: The Pixel 6a is often praised for its consistent image quality, particularly in challenging lighting conditions, leveraging its software processing for features like Night Sight and Magic Eraser. The Galaxy S21 Plus 5G offers strong performance in well-lit conditions and the added benefit of a dedicated telephoto lens for zoomed shots. Some Galaxy S21 Plus 5G users have reported occasional camera app stuttering or heating during extended video recording.
• Video Recording and Front Camera: The Galaxy S21 Plus 5G supports up to 8K video recording and features a 10MP front camera. The Pixel 6a can record 4K video at up to 60 frames per second and includes an 8MP front camera.
