Galaxy S10 vs Galaxy S21 FE 5G

The Samsung Galaxy S10, released in March 2019, and the Samsung Galaxy S21 FE 5G, launched in January 2022, represent different generations within Samsung's smartphone lineup. While both devices run on the Android operating system, the S21 FE 5G benefits from a more recent release, bringing with it updated hardware and a longer software support window. The S10, as an older flagship, offers a more traditional smartphone experience with certain features no longer common in newer models.

The practical lifespan of a smartphone is heavily influenced by its release timeline and the duration of software support it receives.

• Release Timeline: The Galaxy S10 was released in March 2019, making it a significantly older device compared to the Galaxy S21 FE 5G, which launched in January 2022. This age difference directly impacts their remaining support cycles.
• OS Support: The Galaxy S10 received its last major Android operating system update with Android 12, which rolled out in late 2021. It no longer receives regular OS or security updates, though critical security flaws might still be addressed. In contrast, the Galaxy S21 FE 5G launched with Android 12 and is expected to receive major OS updates up to Android 16, extending its software longevity significantly.
• Repairability: Both devices feature glass and aluminum constructions, which generally offer a good balance of aesthetics and durability. User sentiment suggests that replacing components like the battery on the S10 can extend its usable life, indicating a degree of repairability.

Performance is a key differentiator, with the newer S21 FE 5G offering a more contemporary experience compared to the S10.

• Processing Power: The Galaxy S21 FE 5G features a more advanced processor, enabling smoother handling of demanding applications, faster app loading times, and a more fluid multitasking experience. Users engaging in mobile gaming or intensive productivity tasks will likely notice the performance gains. The S10, while still capable for everyday tasks like browsing and messaging, may show its age with more resource-intensive applications.
• Battery Behavior: The Galaxy S21 FE 5G is equipped with a larger 4500 mAh battery, compared to the S10's 3400 mAh battery. This generally translates to longer usage times for the S21 FE 5G, though some users have reported that its battery life can be average, especially with heavy use or 5G connectivity. The S10's battery, particularly in older units, may require more frequent charging or a replacement to last a full day.
• Storage and RAM: Both devices offer various storage configurations. The S10 typically comes with 8GB of RAM, while the S21 FE 5G is available with either 6GB or 8GB of RAM. For most users, both configurations provide sufficient memory for smooth multitasking, though the S10's consistent 8GB across its main models offers a slight edge in this specific aspect. The S10 also includes a microSD card slot for expandable storage, a feature absent in the S21 FE 5G.

Both devices offer high-quality displays, but the S21 FE 5G incorporates newer display technology for a more modern viewing experience.

• Display Technology and Resolution: The Galaxy S10 features a 6.1-inch Dynamic AMOLED display with a resolution of 1440 x 3040 pixels, providing sharp and vibrant visuals. The Galaxy S21 FE 5G has a slightly larger 6.4-inch Dynamic AMOLED 2X display with a resolution of 1080 x 2340 pixels. While the S10 has a higher pixel density, the S21 FE 5G's display is still clear and vibrant for typical viewing.
• Refresh Rate and Brightness: A key difference is the refresh rate; the S21 FE 5G offers a 120Hz refresh rate, resulting in smoother scrolling and more fluid animations compared to the S10's standard 60Hz refresh rate. The S21 FE 5G also boasts a higher peak brightness of 1200 nits, making it more visible in bright outdoor conditions than the S10's 800 nits.
• Screen Protection: The S10 uses Gorilla Glass 6 for screen protection, while the S21 FE 5G features the more robust Gorilla Glass Victus.

Both smartphones provide capable camera systems, with the S21 FE 5G offering some advancements due to its newer hardware.

• Rear Camera System: The Galaxy S10 features a triple-camera setup with a 12 MP wide, 12 MP telephoto (2x optical zoom), and 16 MP ultrawide lens. The Galaxy S21 FE 5G also has a triple-camera system, consisting of a 12 MP wide, 8 MP telephoto (3x optical zoom), and 12 MP ultrawide lens. The S21 FE 5G offers a greater optical zoom capability.
• Photography Performance: The S21 FE 5G generally delivers strong camera performance in various conditions, including low light, with good color accuracy. The S10's camera still takes solid photos in good lighting, but its low-light performance may not match newer devices.
• Video Recording and Front Camera: Both devices are capable of recording 4K video. The S21 FE 5G features a higher resolution 32 MP front camera, compared to the S10's 10 MP front camera, which can be beneficial for selfies and video calls.
