Display Comparison

The Samsung Galaxy S21 FE 5G boasts a vibrant AMOLED display with a 120Hz refresh rate and a peak brightness of 792 nits, offering exceptional clarity and smoothness. The Realme 3i's LCD display is adequate for everyday use but lacks the color accuracy and responsiveness of the S21 FE. The S21 FE's infinite contrast ratio is a significant advantage.

Camera Comparison

The Samsung Galaxy S21 FE 5G's camera system is a major upgrade, offering better image quality, more features (like optical image stabilization), and improved low-light performance. While the Realme 3i's camera is functional, it struggles in challenging conditions and lacks the versatility of the S21 FE.

Performance

The Snapdragon 888 (or Exynos 2100) in the S21 FE 5G delivers significantly faster performance than the Helio P60 in the Realme 3i. Expect smoother multitasking, quicker app loading times, and a much better gaming experience on the S21 FE. The S21 FE's CPU architecture is far more advanced.

Battery Life

Both phones offer impressive battery life. The Realme 3i, with its smaller display and less demanding chipset, can often achieve the advertised 92h endurance rating. The S21 FE 5G also provides excellent battery life, especially considering its more powerful hardware. The S21 FE's 25W wired and 15W wireless charging are also significant advantages over the Realme 3i's 10W wired charging.

Buying Guide

The Realme 3i is ideal for students, first-time smartphone users, or anyone needing a reliable device for calls, texts, and basic apps without breaking the bank. The Samsung Galaxy S21 FE 5G is perfect for power users, mobile gamers, photography enthusiasts, and those who demand a premium experience.
