Apple iPhone 12 mini

  • Extremely compact and pocketable design
  • Powerful A14 Bionic chip for smooth performance
  • MagSafe wireless charging ecosystem

  • Significantly shorter battery life
  • Smaller display may feel cramped
  • Limited charging options compared to S21 FE

Samsung Galaxy S21 FE 5G

  • Longer battery life for all-day use
  • Brighter and larger display for better viewing
  • Faster wired charging and wireless/reverse wireless options

  • Larger size may not suit all users
  • Potential for thermal throttling (especially Exynos variant)
  • Samsung’s software can be polarizing

Display Comparison

The Samsung Galaxy S21 FE 5G boasts a notably brighter display, reaching 792 nits compared to the iPhone 12 mini’s 627 nits. This translates to better outdoor visibility. Both displays share an 'Infinite' (nominal) contrast ratio, typical of OLED panels. While neither specifies refresh rate, the S21 FE’s larger 6.4-inch panel offers more screen real estate. The iPhone 12 mini’s 5.4-inch display is ideal for single-handed use, but the smaller size may feel cramped for media consumption.

Camera Comparison

Both phones offer capable photo and video recording, but details matter. While both are listed as having 'Photo / Video' capabilities, specifics are lacking. The S21 FE’s larger sensor size (likely, though not specified) generally translates to better low-light performance. The iPhone 12 mini’s image processing prioritizes natural colors, while Samsung’s tends towards more saturated and vibrant results. The absence of detailed camera specs makes a definitive judgment difficult, but the S21 FE’s versatility, potentially including a wider range of focal lengths, gives it an edge.

Performance

The iPhone 12 mini’s Apple A14 Bionic (5nm) features a hexa-core CPU with a split core design (2x3.1 GHz Firestorm + 4x1.8 GHz Icestorm), optimized for both performance and efficiency. The Galaxy S21 FE 5G comes in two variants: one with the Qualcomm Snapdragon 888 5G (5nm) and another with the Exynos 2100 (5nm). The Snapdragon 888’s octa-core configuration (1x2.84 GHz Cortex-X1, 3x2.42 GHz Cortex-A78, 4x1.80 GHz Cortex-A55) and the Exynos 2100’s (1x2.9 GHz Cortex-X1, 3x2.80 GHz Cortex-A78, 4x2.2 GHz Cortex-A55) offer more cores, but real-world performance differences are often nuanced. The A14 Bionic generally excels in single-core tasks, while the Snapdragon 888/Exynos 2100 can shine in multi-threaded workloads. Thermal management is a potential concern for the S21 FE, particularly the Exynos variant, which has been reported to throttle under sustained load.

Battery Life

Battery life is where the Galaxy S21 FE 5G decisively wins. Its endurance rating of 92 hours significantly surpasses the iPhone 12 mini’s 69 hours. Both phones support 50% charging in 30 minutes with wired charging (PD2.0/PD3.0). The S21 FE offers 25W wired charging, while the iPhone 12 mini is limited to 20W. The S21 FE also includes 15W wireless charging and reverse wireless charging, features absent on the iPhone 12 mini without the MagSafe/Qi2 ecosystem. While the iPhone 12 mini supports 15W wireless charging via MagSafe and Qi2 (with iOS 17.4), the S21 FE’s overall charging flexibility is superior.

Buying Guide

Buy the Apple iPhone 12 mini if you absolutely prioritize a truly pocketable, one-handed experience and are deeply embedded in the Apple ecosystem. Its A14 Bionic chip still delivers excellent performance for everyday tasks. Buy the Samsung Galaxy S21 FE 5G if you value battery life, a brighter and more vibrant display, and the flexibility of the Android operating system, all without sacrificing significant performance.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in the 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 complete deal-breaker, it can lead to reduced performance over time. The Snapdragon 888 variant generally handles heat more effectively.
❓ Is the 2MP macro camera on the Galaxy S21 FE 5G actually useful?
The 2MP macro camera on the S21 FE is a relatively low-resolution sensor. While it can capture close-up shots, the image quality is often lacking in detail and sharpness compared to the main sensor. It's a nice-to-have feature, but not a primary reason to choose this phone.
❓ Does the Galaxy S21 FE 5G support 90fps in PUBG Mobile?
Yes, the Galaxy S21 FE 5G supports 90fps gameplay in PUBG Mobile with the appropriate graphics settings enabled. This provides a smoother and more responsive gaming experience compared to the standard 60fps.
❓ How does MagSafe on the iPhone 12 mini compare to the wireless charging on the S21 FE?
MagSafe offers a secure magnetic attachment for wireless charging and accessories, providing a more stable connection. The S21 FE’s wireless charging is standard Qi, lacking the magnetic alignment. However, the S21 FE also supports reverse wireless charging, allowing it to charge other devices, a feature absent on the iPhone 12 mini.
