  • Wireless and reverse wireless charging

  • Slower charging speed (25W)
  • Exynos variant may exhibit more thermal throttling

Display Comparison

The Galaxy S21 FE boasts a measured peak brightness of 792 nits, providing excellent visibility in direct sunlight. While the iQOO 7’s display specifications aren’t detailed, it’s likely comparable in brightness. Both phones likely utilize AMOLED panels for vibrant colors and deep blacks. The S21 FE’s ‘Infinite’ contrast ratio (nominal) is typical of AMOLED technology. The iQOO 7’s display tech is unknown, but a high refresh rate is expected given its gaming focus. The S21 FE’s display is a known quantity, offering a reliable and visually pleasing experience.

Camera Comparison

Both phones feature capable camera systems, but details are limited to 'Photo / Video' for both. The iQOO 7’s camera specs are unknown, but its gaming-focused branding suggests a prioritization of fast capture speeds. The S21 FE likely benefits from Samsung’s advanced image processing algorithms, potentially delivering more consistent and visually appealing results. The presence of OIS (Optical Image Stabilization) is expected on both, but sensor sizes and lens apertures are crucial details missing from the provided data. The S21 FE’s camera is likely more versatile due to Samsung’s software features and potentially a wider range of shooting modes.

Performance

Both phones can be equipped with the Qualcomm Snapdragon 888 5G (5nm). However, the S21 FE also has a version with the Exynos 2100 (5nm). The Snapdragon 888’s Cortex-X1 prime core, coupled with A78 performance cores, delivers exceptional performance in both devices. The S21 FE’s Exynos variant may exhibit slightly different thermal characteristics, potentially leading to more throttling under sustained load. Both CPUs share the same core configuration (1x2.84 GHz Cortex-X1, 3x2.42 GHz Cortex-A78, 4x1.80 GHz Cortex-A55), but the S21 FE’s Exynos version has a slightly higher clocked X1 core at 2.9 GHz and A78 cores at 2.80 GHz, and faster A55 cores at 2.2 GHz. The iQOO 7’s focus on gaming suggests optimized thermal management to sustain peak performance for longer durations.

Battery Life

The Galaxy S21 FE has an endurance rating of 92 hours, indicating solid battery life. The iQOO 7’s battery capacity is not specified, but its 120W (China) or 66W (International) wired charging is a significant advantage. The S21 FE takes 30 minutes to reach 50% charge with its 25W charger, while the iQOO 7 can fully charge in just 15 minutes (China) or a still-impressive time with the 66W version. The S21 FE also offers 15W wireless charging and reverse wireless charging, features absent on the iQOO 7. The iQOO 7’s charging speed dramatically reduces downtime, making it ideal for users who frequently need to top up their battery.

Buying Guide

Buy the vivo iQOO 7 if you absolutely need the fastest charging available (120W in China, 66W internationally) and prioritize maximizing gaming performance without concern for software customization. Buy the Samsung Galaxy S21 FE 5G if you prefer a polished, feature-rich software experience, a more versatile camera system, and the convenience of wireless charging and reverse wireless charging, even if it means sacrificing some charging speed.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in the Galaxy S21 FE overheat during extended gaming sessions?
The Exynos 2100 variant of the Galaxy S21 FE has been reported to run warmer than the Snapdragon 888 version, potentially leading to thermal throttling during prolonged gaming. While not a deal-breaker, users prioritizing sustained performance may prefer the Snapdragon variant if available.
❓ Is the 120W charging on the iQOO 7 safe for the battery's long-term health?
vivo employs multiple safety mechanisms to mitigate the potential impact of 120W charging on battery health. While extremely fast charging can theoretically accelerate battery degradation over years of use, the iQOO 7’s charging system is designed to minimize this effect. The 66W international version also charges very quickly while being less aggressive.
❓ How does the software experience differ between the iQOO 7 and the Galaxy S21 FE?
The iQOO 7 likely runs vivo’s Funtouch OS, which is known for its customization options but can be less polished than Samsung’s One UI. The Galaxy S21 FE offers One UI, a mature and feature-rich software experience with a strong emphasis on usability and integration with Samsung’s ecosystem.
❓ Does the Galaxy S21 FE support 90fps or 120fps gaming?
The Galaxy S21 FE supports up to 120Hz refresh rate on its display, and many popular games can be configured to run at 60fps or higher. Whether a game reaches 90fps or 120fps depends on the game's optimization and the device's thermal conditions. The Snapdragon 888 is capable of pushing higher frame rates in many titles.
