Xiaomi 12 Lite NE

  • 67W fast charging for quick top-ups
  • More modern 4nm chipset fabrication
  • Lighter and potentially more ergonomic design

  • Potentially lower peak display brightness
  • Less powerful CPU compared to Snapdragon 888 S21 FE

Samsung Galaxy S21 FE 5G

  • Brighter and more vibrant display
  • Potentially more powerful Snapdragon 888 processor (version dependent)
  • Wireless and reverse wireless charging

  • Slower 25W wired charging
  • Potential for thermal throttling with Exynos 2100 variant

Display Comparison

The Samsung Galaxy S21 FE 5G clearly leads in display quality, achieving a measured peak brightness of 792 nits. This is significantly higher than what we’d expect from the 12 Lite NE, making the S21 FE far more usable in direct sunlight. While the 12 Lite NE’s panel specifications aren’t provided, Samsung’s display technology and brightness advantage are substantial. Both feature an 'Infinite' (nominal) contrast ratio, suggesting deep blacks, but the S21 FE’s higher brightness will translate to a more dynamic and visually appealing experience.

Camera Comparison

Both phones are listed as having 'Photo / Video' capabilities, lacking specific details. However, the S21 FE’s likely larger sensor size (based on Samsung’s flagship camera technology) and potentially wider aperture lenses will likely result in better low-light performance and dynamic range. The 12 Lite NE’s camera system is likely tuned for social media sharing, prioritizing vibrant colors and quick processing. The inclusion of OIS (Optical Image Stabilization) on the S21 FE is a significant advantage for video recording and reducing blur in low-light photos. We can safely assume the 2MP macro camera on both devices offers limited practical benefit.

Performance

The core difference lies in the chipsets. The Galaxy S21 FE 5G utilizes either the Qualcomm Snapdragon 888 5G (5nm) or the Exynos 2100 (5nm), while the Xiaomi 12 Lite NE features the Qualcomm Snapdragon 7 Gen 1 (4nm). The Snapdragon 888, particularly the 2.84GHz Cortex-X1 variant, offers a performance advantage in raw CPU power compared to the 12 Lite NE’s Cortex-A710 based CPU. However, the 4nm process of the Snapdragon 7 Gen 1 should offer better thermal efficiency, potentially mitigating throttling during sustained workloads. The S21 FE’s LPDDR5 RAM (spec not confirmed for 12 Lite NE) further contributes to faster data access. The Exynos 2100 version of the S21 FE is known to have thermal issues, so the Snapdragon variant is preferable.

Battery Life

The Galaxy S21 FE 5G boasts an endurance rating of 92 hours, indicating solid battery life. While the Xiaomi 12 Lite NE’s battery capacity isn’t specified, its 67W wired charging is a major advantage, achieving a 100% charge in just 40 minutes. The S21 FE’s 25W charging, taking 30 minutes to reach 50%, is considerably slower. The S21 FE also supports 15W wireless and reverse wireless charging, features absent on the 12 Lite NE. The faster charging of the 12 Lite NE partially offsets any potential battery capacity disadvantage.

Buying Guide

Buy the Xiaomi 12 Lite NE if you prioritize a lightweight design, extremely fast 67W charging, and a more modern chipset fabrication process (4nm). Buy the Samsung Galaxy S21 FE 5G if you value a brighter, more vibrant display, a potentially more powerful processor (especially the Snapdragon 888 version), and a more established brand ecosystem with a longer track record of software support.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in the S21 FE overheat during demanding tasks like gaming?
The Exynos 2100 variant of the S21 FE is known to be more prone to thermal throttling than the Snapdragon 888 version. Prolonged gaming sessions or intensive app usage can lead to performance drops as the chip heats up. The Xiaomi 12 Lite NE’s Snapdragon 7 Gen 1, built on a 4nm process, is generally more thermally efficient.
❓ Is the 2MP macro camera on either phone actually useful for taking detailed close-up photos?
Generally, 2MP macro cameras on smartphones offer limited detail and image quality. They are often included for marketing purposes but rarely deliver truly impressive macro photography. You'll likely get better results using the main camera in 'close-up' mode.
❓ Can the Samsung Galaxy S21 FE 5G reliably maintain 60fps in graphically intensive games like PUBG or Genshin Impact?
The Snapdragon 888 version of the S21 FE can generally maintain 60fps in PUBG and Genshin Impact at medium to high settings. However, the Exynos 2100 version may experience frame drops during extended gameplay due to thermal throttling. The Xiaomi 12 Lite NE will likely offer stable performance at lower settings.
❓ How does the software experience differ between Xiaomi's MIUI and Samsung's One UI?
Samsung's One UI is generally considered more polished and feature-rich, with a longer track record of software updates. Xiaomi's MIUI is known for its customization options but can sometimes include bloatware and aggressive battery management. Samsung typically offers longer software support for its devices.
