Display Comparison

Both the A52 5G and S21 5G feature displays with an 'Infinite' contrast ratio, indicating excellent black levels. However, the S21 5G edges out the A52 5G in peak brightness, reaching 856 nits compared to the A52 5G’s 787 nits. This translates to slightly better visibility in direct sunlight. While both offer smooth scrolling, the S21 5G’s display technology is likely superior, though not explicitly stated in the provided data, given its flagship status. The A52 5G’s display is still very good, offering a pleasant viewing experience for everyday use.

Camera Comparison

Both phones offer photo and video capabilities, but the S21 5G likely has an advantage in image processing and low-light performance, though specific sensor details are missing. The S21 5G’s flagship status suggests a more sophisticated camera system with potentially larger sensors and better optical image stabilization (OIS). While both phones likely capture good quality images, the S21 5G will likely offer more detail and dynamic range, especially in challenging lighting conditions. The A52 5G provides a solid camera experience for the price, but won’t match the S21 5G’s capabilities.

Performance

The performance gap between these two devices is significant. The S21 5G, equipped with either the Exynos 2100 (International) or Snapdragon 888 5G (USA/China) on a 5nm process, boasts a considerably more powerful CPU and GPU than the A52 5G’s Snapdragon 750G (8nm). The S21 5G’s Cortex-X1 prime core (2.9 GHz or 2.84 GHz depending on region) provides a substantial boost in single-core performance, crucial for responsive app launching and multitasking. The 5nm fabrication process also contributes to better thermal efficiency, potentially reducing throttling during sustained workloads. The A52 5G’s Snapdragon 750G is capable for everyday tasks, but will struggle with graphically intensive games at higher settings.

Battery Life

The Samsung Galaxy A52 5G demonstrates a clear advantage in battery endurance, achieving a measured 111 hours compared to the S21 5G’s 93 hours. This difference is likely due to the more efficient Snapdragon 750G chipset and potentially a larger battery capacity (not specified in the data). Both phones support 25W wired charging, with the A52 5G reaching 50% charge in 30 minutes. The S21 5G adds 15W wireless charging and 4.5W reverse wireless charging, offering greater convenience, but these features come at the cost of overall battery life.

Buying Guide

Buy the Samsung Galaxy A52 5G if you prioritize all-day battery life, a vibrant display for media consumption, and a capable camera system without breaking the bank. Buy the Samsung Galaxy S21 5G if you demand the fastest possible performance for gaming and demanding applications, and appreciate features like faster charging and a more premium build quality, and are willing to pay a premium.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in the S21 5G overheat during prolonged gaming sessions?
While the Exynos 2100 is a powerful chip, it has been known to exhibit some thermal throttling under sustained heavy loads, particularly in the international variant. The 5nm process helps, but demanding games may lead to reduced performance over extended periods. The Snapdragon 888 variant generally handles heat better.
❓ Is the 2MP macro camera on the A52 5G actually useful for taking detailed close-up photos?
Generally, 2MP macro cameras on phones in this price range offer limited detail and image quality. While it can capture close-up shots, don't expect professional-level results. It's more of a novelty feature than a truly useful camera tool.
❓ Can the Samsung Galaxy A52 5G handle graphically intensive games like PUBG at high frame rates?
The A52 5G’s Snapdragon 750G can run PUBG, but you’ll likely need to compromise on graphics settings to achieve consistently smooth frame rates. Expect to play at medium settings for a balanced experience. High settings may result in noticeable lag or stuttering.
❓ What is the real-world difference in charging speed between the 25W charging on both phones?
While both support 25W charging, the S21 5G’s inclusion of Power Delivery 3.0 (PD3.0) may result in slightly faster and more efficient charging with compatible chargers. However, the difference is unlikely to be substantial in most scenarios.
