Display Comparison

The Galaxy S21 5G’s display is a clear winner. It boasts a higher peak brightness (856 nits vs A71’s estimated 600 nits), an infinite contrast ratio, and likely a more vibrant color reproduction thanks to its AMOLED technology. While the A71 5G UW has a large 6.7-inch display, the S21 5G’s smaller, but superior panel provides a more immersive and visually appealing experience.

Camera Comparison

The Galaxy S21 5G’s camera system is more versatile and capable. While both phones offer decent image quality, the S21 5G’s larger sensor, improved image processing, and additional features (like Director's View and Single Take) give it a significant edge. Expect better low-light performance and more detailed photos and videos from the S21 5G.

Performance

Performance is where the S21 5G truly shines. Its Exynos 2100 (or Snapdragon 888 in the US/China version) chipset is significantly faster than the A71 5G UW’s Snapdragon 765G. This translates to smoother multitasking, faster app loading times, and a better gaming experience. The S21 5G handles demanding tasks with ease, while the A71 5G UW may show some lag when pushed.

Battery Life

The A71 5G UW has a larger battery capacity (likely 4500mAh, though not explicitly stated) and an endurance rating of 93h, suggesting excellent battery life. The S21 5G, while also offering good battery life (93h endurance rating), may not last quite as long under heavy use due to its more powerful processor and brighter display.

Buying Guide

The Samsung Galaxy A71 5G UW is ideal for users seeking a large display, long battery life, and 5G connectivity without breaking the bank. It's a great choice for media consumption and everyday tasks. The Samsung Galaxy S21 5G is perfect for power users, photographers, and gamers who demand top-tier performance, a stunning display, and a versatile camera system, and are willing to pay a premium.
