Samsung Galaxy S21 Ultra 5G

  • Superior display brightness and quality
  • More versatile and advanced camera system
  • Longer battery life and endurance

  • Significantly higher price
  • Larger and heavier form factor

Samsung Galaxy S21 FE 5G

  • More affordable price point
  • Excellent performance for the price
  • Compact and manageable size

  • Less bright display
  • Less capable camera system

Display Comparison

The S21 Ultra’s display is a clear standout, achieving a measured peak brightness of 1023 nits compared to the S21 FE’s 792 nits. This translates to significantly better visibility in direct sunlight. Both feature 'Infinite' contrast ratios, but the Ultra’s larger size and higher resolution (not specified in data, but known to be higher) contribute to a more immersive viewing experience. While both likely utilize AMOLED technology, the S21 Ultra’s panel is expected to have a more sophisticated LTPO implementation, enabling a wider range of variable refresh rates for improved power efficiency. The S21 FE’s display, while still excellent, is a noticeable step down in brightness and potentially color accuracy.

Camera Comparison

The S21 Ultra’s camera system is significantly more advanced. While both phones offer photo and video capabilities, the S21 Ultra’s larger sensors and additional telephoto lenses provide superior image quality, particularly in low-light conditions and at longer zoom ranges. The S21 Ultra’s ability to capture detailed images at higher zoom levels is a key differentiator. The S21 FE’s camera is still capable, but lacks the versatility and advanced features of the Ultra. The inclusion of a 2MP macro camera on the S21 FE is largely inconsequential, offering minimal benefit over the main sensor.

Performance

Both phones are available in Exynos 2100 and Snapdragon 888 5G variants, creating a complex performance landscape. The S21 Ultra’s international version features a slightly lower clocked Cortex-X1 core (2.9 GHz vs 2.84 GHz in the S21 FE Version 1), but the USA/China version of the S21 Ultra has a higher clocked X1 (2.84 GHz vs 2.9 GHz in S21 FE Version 2). This suggests minimal real-world performance differences between the chipsets. However, the S21 Ultra’s superior thermal design, due to its larger size, likely allows for sustained peak performance for longer durations, minimizing throttling during demanding tasks. Both utilize LPDDR5 RAM, but the S21 Ultra’s 12GB configuration (available in multiple storage options) provides a slight edge in multitasking.

Battery Life

The S21 Ultra boasts an endurance rating of 114 hours, significantly exceeding the S21 FE’s 92 hours. This translates to a noticeable difference in real-world battery life, especially for power users. Both support 25W wired charging with PD3.0 and 15W wireless charging, but the Ultra’s larger battery capacity means it takes longer to fully charge. The S21 FE’s 50% charge in 30 minutes claim is a useful metric, but the overall endurance advantage remains with the S21 Ultra.

Buying Guide

Buy the Samsung Galaxy S21 Ultra 5G if you demand the absolute best display quality, require the most versatile camera system with superior zoom capabilities, and prioritize maximum battery endurance. Buy the Samsung Galaxy S21 FE 5G if you prioritize value, want a flagship-level experience without the premium price tag, and are comfortable with slightly less advanced camera features and a less bright display.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in either phone suffer from significant overheating during prolonged gaming sessions?
While both the Snapdragon 888 and Exynos 2100 variants can generate heat, the S21 Ultra’s larger chassis and improved thermal design generally mitigate overheating better than the S21 FE. Users have reported slightly more throttling on the Exynos 2100 version of the S21 FE during extended gaming, but it’s not a deal-breaker.
❓ Is the 2MP macro camera on the S21 FE actually useful for taking detailed close-up photos?
The 2MP macro camera on the S21 FE is largely a marketing feature. Its low resolution and lack of optical image stabilization result in images that are often soft and lack detail. The main sensor can produce better close-up shots with digital zoom.
❓ Can the S21 FE reliably maintain 60fps in demanding games like PUBG or Genshin Impact?
Yes, the S21 FE can generally maintain 60fps in PUBG and Genshin Impact at medium to high settings. However, users may experience occasional frame drops during intense scenes, particularly on the Exynos variant. The S21 Ultra offers a smoother and more consistent gaming experience.
❓ What is the real-world difference in charging speed between the two phones, considering both support 25W wired charging?
While both support 25W charging, the S21 Ultra’s larger battery takes longer to fully charge. The S21 FE’s claim of 50% charge in 30 minutes is accurate, but a full charge will still take considerably longer than on the S21 Ultra, despite the same wattage.
