Camera Comparison

The Z Flip3 has a dual-camera system (12MP wide, 12MP ultrawide) that delivers good quality photos and videos. The S21 FE 5G features a more versatile triple-camera system (12MP wide, 12MP ultrawide, 8MP telephoto) with optical zoom, providing more creative options. The S21 FE generally produces more detailed and vibrant images.

Performance

Both phones are powered by the Snapdragon 888 5G, ensuring smooth performance for most tasks. The S21 FE 5G potentially has a slight edge due to the possibility of an Exynos 2100 variant, which can sometimes offer slightly better efficiency. However, both offer excellent performance for everyday use and gaming.

The S21 FE 5G significantly outperforms the Z Flip3 5G in battery life, offering an endurance rating of 92 hours compared to the Z Flip3's 69 hours. The S21 FE also supports 25W fast charging, while the Z Flip3 is limited to 15W. This makes the S21 FE a much better choice for users who need all-day battery life.

Buying Guide

The Samsung Galaxy Z Flip3 5G is ideal for fashion-conscious users who want a unique and compact phone and don't mind sacrificing some battery life. The Galaxy S21 FE 5G is a better choice for users who prioritize battery life, faster charging, and a more conventional smartphone experience at a competitive price.
