Samsung Galaxy S21 FE 5G

  • Potentially newer processor version (Exynos 2100 v2)
  • Slightly more affordable price point (depending on retailer)
  • Access to the latest Samsung software features

  • Significantly shorter battery life
  • Less bright display
  • Potential for chipset variation (Snapdragon vs Exynos)

Samsung Galaxy S21+ 5G

  • Superior battery life (114h endurance)
  • Brighter display for better outdoor visibility
  • More consistent performance due to better thermal management

  • Older processor generation
  • Potentially higher price (depending on retailer)
  • Chipset variation (Snapdragon vs Exynos)

Display Comparison

The S21+ boasts a noticeably brighter display, reaching 883 nits compared to the S21 FE’s 792 nits. This translates to better outdoor visibility, particularly in direct sunlight. Both displays share an 'Infinite' contrast ratio, indicating excellent black levels typical of Samsung’s AMOLED panels. While both likely utilize a 120Hz refresh rate, neither specification explicitly states LTPO technology, meaning adaptive refresh rate functionality may be limited compared to newer Samsung models. The S21+'s higher peak brightness is a tangible benefit for media consumption and everyday use.

Camera Comparison

Both phones share a similar camera setup, focusing on photo and video capabilities. The key difference lies in image processing and potential sensor calibration. While detailed sensor specs are absent, the S21+’s consistent image quality reputation suggests refined software algorithms. The inclusion of OIS (Optical Image Stabilization) on the main sensor is standard for both. The 2MP macro cameras on both devices are largely a marketing feature, offering limited practical benefit due to their small sensor size and fixed focus. The S21+'s image processing is likely more mature, resulting in more consistent results.

Performance

The chipset situation is complex. The S21 FE comes in two versions: a Snapdragon 888 and an Exynos 2100. The S21+ also has both variants, but geographically separated – Snapdragon for USA/China, Exynos for International markets. The S21 FE’s Version 2 (Exynos) features a slightly faster Cortex-X1 core (2.9 GHz vs 2.84 GHz in the S21+’s US/China Snapdragon version). However, the core architecture is fundamentally the same. Both phones utilize LPDDR5 RAM, but the S21+'s thermal management, benefiting from a slightly larger chassis, may allow for sustained performance under heavy load. The real-world performance difference will be minimal for most users.

Battery Life

Battery life is where the S21+ truly shines. Its endurance rating of 114 hours significantly surpasses the S21 FE’s 92 hours. This translates to a full day of heavy use, while the S21 FE may require a top-up for power users. Both phones support 25W wired charging, achieving 50% charge in approximately 30 minutes with PD3.0 compatibility. Both also offer 15W wireless charging and reverse wireless charging, though the S21+ offers a slightly more efficient 4.5W reverse wireless compared to the S21 FE’s unspecified rate. The larger battery capacity in the S21+ is the primary driver of its superior endurance.

Buying Guide

Buy the Samsung Galaxy S21 FE 5G if you prioritize the latest processor generation and are comfortable with slightly shorter battery life. It’s ideal for users who frequently engage in demanding tasks like mobile gaming and benefit from the potential performance edge of the Cortex-X1 core. Buy the Samsung Galaxy S21+ 5G if you value all-day battery life, a brighter and more visible display, and a consistently smooth experience, even if it means sacrificing the absolute latest chipset iteration.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in the S21 FE overheat during prolonged gaming sessions?
While the Exynos 2100 is a capable chip, it's known to run slightly warmer than the Snapdragon 888. The S21 FE's thermal design is adequate, but extended gaming at maximum settings may lead to some throttling. The S21+'s slightly larger chassis and potentially more efficient thermal solution may mitigate this issue.
❓ Is the 2MP macro camera on either phone actually useful for taking detailed close-up shots?
Unfortunately, the 2MP macro cameras on both the S21 FE and S21+ are largely a marketing gimmick. Their small sensor size and fixed focus limit their ability to capture truly detailed macro shots. Results are often soft and lack clarity. Relying on the main sensor with digital zoom will generally yield better results.
❓ Can the S21 FE reliably maintain 60fps in demanding games like PUBG or Genshin Impact?
The S21 FE, regardless of the chipset variant, can generally maintain 60fps in PUBG and Genshin Impact at medium to high settings. However, prolonged gaming sessions may lead to frame drops due to thermal throttling. The S21+ offers a more consistent experience due to its better thermal management.
❓ What is the difference between the reverse wireless charging capabilities of the S21 FE and S21+?
The S21+ offers 4.5W reverse wireless charging, while the S21 FE’s reverse wireless charging wattage is not explicitly specified. This means the S21+ can charge accessories like earbuds or smartwatches slightly faster than the S21 FE, though both are relatively slow compared to wired charging.
