Samsung Galaxy S21 FE 5G

  • Powerful Snapdragon 888 or Exynos 2100 chipset
  • Brighter and more vibrant display (792 nits)
  • Faster charging with wireless and reverse wireless options

  • Higher price point
  • Battery life is comparable to the M33 despite a more powerful processor
  • Potential for thermal throttling under sustained load

Display Comparison

The S21 FE 5G boasts a significantly brighter display, reaching a measured 792 nits, compared to an unspecified brightness for the M33. While both utilize AMOLED technology, the S21 FE’s higher peak brightness translates to better visibility outdoors. The S21 FE’s ‘Infinite’ contrast ratio (nominal) suggests deeper blacks and more vivid colors. The M33’s display specifications are less detailed, suggesting a more basic panel aimed at cost savings. The lack of LTPO on either device means refresh rate scaling isn't as efficient as on higher-end models.

Camera Comparison

Both phones feature a 'Photo / Video' camera system, but details are sparse. The S21 FE likely benefits from more advanced image processing algorithms and potentially larger sensor sizes, typical of flagship devices. While the M33 may offer a competitive camera in its price range, the S21 FE’s superior processing power and potentially better optics will result in sharper, more detailed images, especially in low-light conditions. The presence of OIS (Optical Image Stabilization) is likely on the S21 FE, further enhancing image quality and video stabilization. We can assume the M33 includes lower-resolution auxiliary cameras, while the S21 FE will have more capable supporting lenses.

Performance

The core difference lies in the chipsets. The S21 FE 5G comes in two variants: one with the Qualcomm Snapdragon 888 5G (5nm) and another with the Exynos 2100 (5nm). Both are significantly more powerful than the M33’s Exynos 1280 (5nm). The Snapdragon 888’s Cortex-X1 prime core (2.84 GHz or 2.9 GHz depending on the version) provides a substantial performance boost over the M33’s Cortex-A78 cores (2.4 GHz). The S21 FE also benefits from potentially faster RAM, though the specific LPDDR version isn’t specified. This translates to smoother multitasking, faster app loading times, and superior gaming performance on the S21 FE. The Exynos 1280 is capable, but will show its limitations in demanding tasks.

Battery Life

Both devices achieve an impressive Endurance rating of 92h, suggesting similar real-world battery life despite the M33’s unspecified mAh capacity. However, the S21 FE offers faster charging at 25W with PD3.0, claiming 50% charge in 30 minutes, and adds 15W wireless charging and reverse wireless charging – features absent on the M33. The M33’s 25W wired charging and 4.5W reverse wired charging are slower and less versatile. The S21 FE’s charging flexibility provides a more convenient user experience.

Buying Guide

Buy the Samsung Galaxy M33 if you need a long-lasting battery and prioritize affordability above all else. It’s ideal for users who primarily browse, use social media, and occasionally game. Buy the Samsung Galaxy S21 FE 5G if you prefer a faster, more responsive experience with a brighter, more vibrant display, and are willing to spend a bit more for flagship-level performance and a more versatile camera system.

Frequently Asked Questions

❓ Does the Exynos 1280 in the Galaxy M33 overheat during prolonged gaming sessions?
While the Exynos 1280 is a capable chip, it's less thermally efficient than the Snapdragon 888 or Exynos 2100 found in the S21 FE. Expect some throttling during extended gaming, potentially leading to reduced frame rates. The M33 is best suited for casual gaming rather than demanding titles at maximum settings.
❓ Is the 25W charging on the S21 FE truly faster than the M33's 25W charging, and what's the real-world difference?
Yes, the S21 FE’s 25W charging with PD3.0 is more efficient. While both are rated at 25W, PD3.0 allows for dynamic voltage adjustment, resulting in faster charging times. The S21 FE claims 50% charge in 30 minutes, while the M33 will likely take longer to reach the same level.
❓ Does the S21 FE support high frame rate gaming (90fps or higher) in popular titles like PUBG Mobile?
The S21 FE, with its Snapdragon 888 or Exynos 2100, is capable of running PUBG Mobile at high frame rates (60fps or higher) depending on the graphics settings. Achieving 90fps may require lowering the graphics settings, but the hardware is certainly capable of delivering a smooth gaming experience.
❓ How significant is the difference in display quality between the two phones for everyday use like watching videos and browsing the web?
The difference is noticeable. The S21 FE’s brighter display makes content more vibrant and easier to see outdoors. Colors will appear more accurate and blacks will be deeper. While the M33’s display is adequate, the S21 FE provides a more immersive and enjoyable viewing experience.
