Display Comparison

Both phones feature excellent displays, but the iQOO 3 5G edges out the S21 FE with a slightly higher peak brightness of 848 nits versus 792 nits. While both have 'infinite' contrast ratios (likely referring to AMOLED technology), the iQOO 3's brighter screen offers better visibility in direct sunlight. Both offer vibrant colors and smooth scrolling.

Camera Comparison

The S21 FE generally offers a more versatile camera system with multiple lenses (wide, ultrawide, telephoto). The iQOO 3 5G's camera is capable, but lacks the same level of flexibility. Image processing and software features are also typically stronger on the S21 FE, resulting in more consistent and pleasing results across different shooting scenarios. Low-light performance is generally better on the S21 FE.

Performance

The iQOO 3 5G utilizes the Snapdragon 865, a proven powerhouse. The S21 FE's performance varies depending on the chipset – Snapdragon 888 or Exynos 2100. While both are capable, the Snapdragon 888 generally offers a slight edge in raw performance and efficiency. The iQOO 3's CPU configuration is also well-balanced for sustained performance.

Battery Life

This is where the iQOO 3 5G truly shines. Its endurance rating of 118h significantly surpasses the S21 FE's 92h. Coupled with its 55W fast charging (reaching 50% in just 15 minutes), the iQOO 3 5G offers exceptional battery life and quick top-ups.

Buying Guide

The vivo iQOO 3 5G is ideal for gamers and power users who prioritize battery life and raw performance. The Samsung Galaxy S21 FE 5G is a better choice for those who value a streamlined software experience, a more compact design, and a well-rounded camera system, especially if they prefer Samsung's ecosystem.
