  • Wireless Charging: Includes wireless charging and reverse wireless charging, which is a premium feature not present in Redmi 12.

Xiaomi Redmi 12 Strengths:

  • Bigger Battery: The 5000mAh battery is larger and likely to offer better battery endurance on paper.
  • More recent Android OS: Comes with Android 13 out of the box, but this is offset by software update commitment of the S21FE.
  • Lower price: The Xiaomi Redmi 12 is in a lower price tier and would appeal to users on a lower budget.
  • Additional Lenses: The Xiaomi Redmi 12 offers a Wide Angle and Macro lens, which the S21 FE does not have.

Trade-offs and Limitations:

  • S21 FE: The absence of expandable storage and a smaller battery than the Redmi 12, as well as charging brick, could be a drawback for some users.
  • Redmi 12: The performance is significantly lower, and the display and camera features aren't as advanced as the S21 FE. Also missing wireless charging and a lower brightness screen.

3. User Profiles and Recommendations

  • Samsung Galaxy S21 FE 5G: Ideal for users who prioritize performance, display quality, a more advanced camera experience, and premium features. It's well-suited for gamers, social media enthusiasts, and those who want a smoother, more versatile smartphone experience.
  • Xiaomi Redmi 12: Best for budget-conscious users who prefer a larger screen and longer battery life. It is suitable for everyday tasks, casual media consumption, and users who don’t need high-end performance or advanced camera capabilities.

4. Buying Decision Framework

To decide between these phones, ask yourself the following:

  1. How important is performance to you? If you need a snappy, lag-free experience and enjoy gaming, the S21 FE is the clear choice. If you only use basic apps and casual games, then the Redmi 12 is sufficient.
  2. How crucial is display quality and outdoor visibility? If you spend a lot of time outdoors or value a vibrant, high-contrast screen, the S21 FE’s AMOLED display will be significantly better.
  3. What are your photography priorities? If you want versatile cameras with good quality, OIS, optical zoom, and excellent video capabilities, the S21 FE wins. But if you need a wide angle and macro lens at the cost of other features, then the Redmi 12 might be a better option.

Scenario-Based Recommendations:

  • The Power User: If you need a phone for gaming, multitasking, and demanding apps, the Samsung Galaxy S21 FE 5G is the right choice.
  • The Casual User: If you want a budget-friendly phone for everyday use, with a bigger screen and battery life, the Xiaomi Redmi 12 will suffice.
  • The Photography Enthusiast: If you want a versatile camera with better video quality and low-light capabilities, the Samsung Galaxy S21 FE 5G is the better option, while if you need the extra wide angle and macro lens in the rear, then the Xiaomi Redmi 12 is a better fit.

My Choice

If I were choosing between these two phones, I would opt for the Samsung Galaxy S21 FE 5G. My decision is driven by a few key factors:

  1. Performance: As someone who uses my phone for a variety of tasks, including app testing and gaming, the significantly superior performance of the Snapdragon 888 chipset is a must-have.
  2. Display Quality: The AMOLED display with its 120Hz refresh rate is critical for my daily use. The brightness is also paramount as I'm often outdoors, and the S21 FE's screen has very high peak brightness.
  3. Camera Versatility: While the Redmi 12 has its merits, the S21 FE’s camera with Optical Image Stabilisation, better video quality and low-light performance, coupled with telephoto lens are more crucial for my creative work and content creation.
  4. Audio quality: I watch a lot of movies on the go, so having a Dolby Atmos supported and a stereo speaker setup is important to me.

The absence of expandable storage doesn't bother me that much as I can use cloud storage, and the slightly smaller battery is a trade-off I am willing to make for the performance, camera and other superior features.
