  • Wireless and reverse wireless charging

  • Slower charging speed
  • Potential for thermal throttling (Exynos variant)
  • Higher price

Display Comparison

The Samsung Galaxy S21 FE 5G boasts a significantly brighter display, reaching 792 nits compared to the Realme 9 Pro+'s 613 nits. This translates to better visibility outdoors under direct sunlight. While both utilize AMOLED technology, the S21 FE’s higher peak brightness and likely superior color calibration (though not specified in the data) provide a more immersive viewing experience. The S21 FE also benefits from an 'Infinite' contrast ratio, suggesting deeper blacks and more dynamic visuals. The Realme 9 Pro+ lacks specific contrast ratio data, suggesting it may not match the S21 FE's visual punch.

Camera Comparison

Both phones feature capable photo and video capabilities, but detailed sensor information is lacking. Without specifics, it’s difficult to make a definitive judgment. However, the market positioning of the S21 FE suggests a more refined image processing pipeline and potentially better low-light performance. The Realme 9 Pro+ likely focuses on delivering vibrant, social media-ready images. The absence of details regarding sensor size and OIS on both devices makes a precise comparison impossible, but the S21 FE’s brand reputation suggests a more consistent and versatile camera system.

Performance

The performance landscape is more complex. The Samsung Galaxy S21 FE 5G comes in two variants: one with the Qualcomm Snapdragon 888 (5nm) and another with the Exynos 2100 (5nm). Both chips are built on a 5nm process, offering greater efficiency than the Realme 9 Pro+'s Mediatek Dimensity 920 (6nm). The Snapdragon 888, particularly the 2.9 GHz Cortex-X1 variant, offers a performance edge in CPU-intensive tasks. However, the Dimensity 920’s Cortex-A78 cores provide strong multi-core performance. The 5nm process of the S21 FE’s chips *should* translate to better thermal management, though the Exynos variant has been known to throttle under sustained load. The Realme 9 Pro+ may offer a more consistent experience under prolonged gaming due to its larger node size, but will likely fall behind in peak performance.

Battery Life

The Realme 9 Pro+ compensates for its smaller endurance rating (117h) with significantly faster charging. Its 60W wired charging, supporting PD3.0, can fully charge the device in just 44 minutes. The Samsung Galaxy S21 FE 5G, with a 25W wired charging speed, takes considerably longer, reaching only 50% in 30 minutes. The S21 FE also offers 15W wireless and reverse wireless charging, features absent on the Realme 9 Pro+. While the S21 FE’s endurance rating is 92h, the Realme 9 Pro+'s faster charging mitigates concerns about battery life for many users.

Buying Guide

Buy the Realme 9 Pro+ if you need blazing-fast 60W charging and prioritize a phone that can quickly top up between uses. It's ideal for users who frequently travel or have limited access to power outlets. Buy the Samsung Galaxy S21 FE 5G if you prefer a brighter, more vibrant display, potentially faster processing speeds (depending on the version), and the established ecosystem and software support of Samsung.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in the Samsung Galaxy S21 FE 5G overheat during gaming?
The Exynos 2100 variant of the S21 FE has been reported to experience thermal throttling under sustained heavy loads, such as prolonged gaming sessions. While not a universal issue, users should be aware that performance may decrease over time to manage heat. The Snapdragon 888 variant generally performs better in this regard.
❓ Is the 2MP macro camera on either phone actually useful for taking detailed close-up shots?
Generally, 2MP macro cameras on phones in this price range offer limited detail and image quality. They are often included for marketing purposes but rarely deliver truly impressive macro photography. Expect soft images and limited dynamic range.
❓ Does the Samsung Galaxy S21 FE 5G support 90fps gameplay in popular titles like PUBG Mobile?
The Samsung Galaxy S21 FE 5G *can* support 90fps gameplay in PUBG Mobile, but it requires enabling the 'Extreme' graphics setting and frame rate option within the game. Performance will depend on the specific chipset (Snapdragon or Exynos) and the device's thermal conditions.
❓ How does the Realme 9 Pro+'s 60W charging compare to other fast charging technologies?
60W charging is considered very fast and significantly quicker than the 25W charging on the S21 FE. It's comparable to some 65W or 67W charging solutions found on other Realme and Oppo devices, and substantially faster than standard 18W or 30W charging.
