Galaxy S21 FE 5G Vs Xiaomi 12T

The Samsung Galaxy S21 FE 5G, released in January 2022, and the Xiaomi 12T, launched in October 2022, are both Android smartphones designed to offer a balanced experience for everyday users. While the Galaxy S21 FE 5G integrates Samsung's established ecosystem and a versatile camera setup, the Xiaomi 12T focuses on rapid charging capabilities and a high-resolution main camera. Both devices run on the Android operating system, though they feature distinct user interfaces: Samsung's One UI and Xiaomi's MIUI.

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

• Software Longevity: The Samsung Galaxy S21 FE 5G was launched with Android 12 and was promised four years of Android OS updates and five years of security updates from its release. This means it is expected to receive major Android updates up to Android 16 and security patches until January 2027. In contrast, the Xiaomi 12T, also launched with Android 12, was initially slated for three major Android OS updates and four years of security updates. However, as of March 2026, Xiaomi has announced the end of software support for its 12 series, including the 12T, meaning it will no longer receive HyperOS updates or security patches.
• Physical Durability: The Galaxy S21 FE 5G features a Gorilla Glass Victus front and an IP68 rating for dust and water resistance, indicating a higher level of protection against environmental elements. The Xiaomi 12T comes with Gorilla Glass 5 on the front and has an IP53 rating, offering splash and dust resistance but not full submersion protection.
• Repairability: While specific repairability scores can vary by region and repair service, both devices are generally designed with modern smartphone construction, which can present challenges for user-level repairs. Professional repair services are typically recommended for both models.

Both smartphones deliver capable performance for daily tasks, though they achieve this with different internal components.

• Processing Power: The Galaxy S21 FE 5G is powered by either a Qualcomm Snapdragon 888 or an Exynos 2100 processor, depending on the region. These processors handle demanding applications and multitasking smoothly, providing a responsive user experience. The Xiaomi 12T features a MediaTek Dimensity 8100-Ultra processor, which is also designed to offer strong performance for gaming and intensive applications, with users reporting good thermal management.
• Multitasking and Storage: Both devices typically come with 8GB of RAM, allowing for efficient multitasking and app switching. Storage options for both models include 128GB and 256GB, providing ample space for apps, photos, and media. Neither phone offers expandable storage via a microSD card.
• Battery Behavior: The Xiaomi 12T is equipped with a larger 5000mAh battery, which generally provides a full day or more of use for many users. The Galaxy S21 FE 5G has a 4500mAh battery, which typically lasts a full day with moderate usage, though heavy users might find themselves needing to charge it by the evening. Some users of the S21 FE have noted that battery life can be less consistent, particularly when using the 120Hz display and 5G connectivity.

The visual experience on both devices is vibrant and clear, catering to media consumption and everyday interactions.

• Display Technology and Clarity: The Samsung Galaxy S21 FE 5G features a 6.4-inch Dynamic AMOLED 2X display with a resolution of 1080 x 2340 pixels, offering sharp images and deep blacks. The Xiaomi 12T sports a slightly larger 6.67-inch AMOLED display with a higher resolution of 1220 x 2712 pixels, providing a crisp viewing experience. Both displays support HDR10+ for enhanced contrast and color.
• Smoothness and Brightness: Both phones offer a 120Hz refresh rate, contributing to smooth scrolling and fluid animations. For outdoor visibility, the Galaxy S21 FE 5G can reach a peak brightness of 800 nits, making it suitable for use in bright conditions. The Xiaomi 12T has a typical brightness of 500 nits and can reach a peak of 900 nits, also ensuring good visibility outdoors.
• Viewing Experience: The slightly larger screen of the Xiaomi 12T might offer a more expansive viewing area for media, while the S21 FE's display is known for its excellent color accuracy.

Both smartphones offer capable camera systems, each with distinct strengths in photography and videography.

• Rear Camera Systems: The Samsung Galaxy S21 FE 5G features a versatile triple-camera setup, including a 12MP main sensor with optical image stabilization (OIS), a 12MP ultrawide lens, and an 8MP telephoto lens with 3x optical zoom and OIS. This dedicated telephoto lens allows for clear zoomed-in shots. The Xiaomi 12T also has a triple-camera system, highlighted by a high-resolution 108MP main sensor with OIS, an 8MP ultrawide lens, and a 2MP macro lens. The 108MP sensor uses pixel-binning technology to produce detailed 12MP photos.
• Photography Performance: In daylight, both phones capture vibrant and detailed images. The Galaxy S21 FE 5G is known for its consistent color science across its main and ultrawide lenses, though some users report the ultrawide can have inconsistent color profiles. The Xiaomi 12T's main camera delivers sharp photos with good dynamic range, but its ultrawide and macro lenses are generally considered less capable. For low-light conditions, the S21 FE performs well with ambient light, but may struggle in very dark environments, while the Xiaomi 12T offers decent low-light performance with its main sensor.
• Video Recording and Front Camera: The S21 FE 5G supports 4K video recording at 60 frames per second (fps) on both its main and front cameras, and can record super slow-motion video. The Xiaomi 12T records 4K video at 30fps with its main camera and 1080p at 60fps with its front camera. Both devices feature capable front-facing cameras for selfies and video calls, with the S21 FE having a 32MP sensor and the Xiaomi 12T a 20MP sensor.
