Display Comparison

The Samsung Galaxy S21 FE 5G boasts a significantly brighter display, reaching 792 nits compared to the Infinix Zero X Pro’s 515 nits. This translates to superior visibility outdoors under direct sunlight. While both feature similar resolutions, the S21 FE’s contrast ratio is listed as 'Infinite (nominal)', suggesting a superior OLED panel with deeper blacks. The Infinix Zero X Pro’s display, while adequate, will appear less vibrant and dynamic in comparison. The S21 FE’s higher brightness also benefits HDR content consumption.

Camera Comparison

Both phones offer photo and video capabilities, but the details matter. While specific sensor details for the Infinix Zero X Pro are missing, the S21 FE’s camera system benefits from Samsung’s advanced image processing algorithms. The S21 FE likely features a larger main sensor, enabling better low-light performance and dynamic range. The Zero X Pro’s camera is likely to be competitive in good lighting conditions, but will likely fall behind in challenging scenarios. The inclusion of OIS (Optical Image Stabilization) on the S21 FE is a significant advantage for video recording and reducing blur in low-light photos. We'd caution against relying heavily on the 2MP macro cameras found on many phones in this price range, including potentially the Zero X Pro.

Performance

The performance gap is substantial. The Samsung Galaxy S21 FE 5G, equipped with either the Qualcomm Snapdragon 888 (5nm) or Exynos 2100 (5nm), offers a considerable leap in processing power over the Infinix Zero X Pro’s MediaTek Helio G95 (12nm). The Snapdragon 888’s Cortex-X1 prime core and more efficient 5nm process provide a noticeable advantage in demanding applications and gaming. The G95, while capable for everyday tasks, will struggle with sustained heavy workloads, potentially leading to throttling. The S21 FE’s LPDDR5 RAM further enhances responsiveness. The two versions of the S21 FE have slightly different CPU clock speeds, but both are significantly faster than the Zero X Pro.

Battery Life

Despite having a smaller battery, the Samsung Galaxy S21 FE 5G’s endurance rating is 92 hours, compared to the Infinix Zero X Pro’s 119 hours. This is due to the more efficient chipset in the S21 FE. However, the Infinix Zero X Pro’s 45W wired charging is significantly faster than the S21 FE’s 25W charging, achieving 40% charge in just 15 minutes. The S21 FE takes 30 minutes to reach 50%. The S21 FE also offers 15W wireless charging and reverse wireless charging, features absent on the Zero X Pro.

Buying Guide

Buy the Infinix Zero X Pro if you need exceptional battery life and fast charging, and prioritize value over absolute performance. It’s perfect for users who frequently travel or rely heavily on their phone throughout the day. Buy the Samsung Galaxy S21 FE 5G if you prefer a brighter, more color-accurate display, a significantly faster processor for demanding tasks like gaming and video editing, and the broader ecosystem benefits of the Samsung brand.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in the S21 FE overheat during prolonged gaming sessions?
While the Exynos 2100 can get warm under sustained load, Samsung implemented thermal management solutions to mitigate overheating. The 5nm process and efficient design generally prevent significant throttling, but performance may slightly decrease after extended gaming. The Snapdragon 888 variant generally runs cooler.
❓ Is the 45W charging on the Infinix Zero X Pro compatible with Power Delivery (PD) chargers?
The Infinix Zero X Pro utilizes its own proprietary 45W charging protocol. While it may work with some PD chargers, it's best to use the included charger to ensure optimal charging speeds and safety. Using a non-compatible charger may result in slower charging or potential compatibility issues.
❓ How does the Helio G95 handle graphically intensive games like PUBG Mobile?
The Helio G95 can run PUBG Mobile, but you'll likely need to lower the graphics settings to achieve a consistently smooth frame rate. Expect some frame drops during intense firefights. The S21 FE's Snapdragon 888 or Exynos 2100 will provide a significantly smoother and more stable gaming experience at higher settings.
❓ What kind of video recording capabilities does the Infinix Zero X Pro offer?
While specific details are limited, the Infinix Zero X Pro supports video recording. However, it likely lacks the advanced features found on the S21 FE, such as 8K recording and advanced stabilization. Expect good results in well-lit conditions, but performance may suffer in low light.
