  • Redmi A1+: Users will sacrifice in nearly every area except battery and physical size. Its performance is very basic, the display isn't great, and the camera is quite limited. It's best suited for users on a tight budget who need basic functionality.

    • Power users: Gamers, content creators, and heavy multitaskers will love the raw performance and vibrant display.

4. Buying Decision Framework

Here are three questions to help you decide:

  1. What is your budget? If you have a tight budget, the Redmi A1+ is an obvious choice. If you can spend more, the S21 FE is a massive upgrade.
  2. How important is performance and quality? If you care about smooth performance, gaming, and a vibrant display, the S21 FE is the only real choice. The A1+ isn't great for anything performance intensive.
  3. What are your main use cases? If you only need basic calling and messaging, and have a low budget, then the A1+ can suffice. If you're going to be taking pictures, watching videos, using apps or gaming, you will want to go with the S21 FE.

  • Scenario 4: A user on a very tight budget who would like a phone with a long lasting battery.

What Would I Choose?

Personally, I'd go with the Samsung Galaxy S21 FE 5G without hesitation. As a tech journalist and someone who uses their smartphone heavily, the massive differences in display quality, performance, and camera capabilities are simply too significant to ignore. Yes, it's more expensive than the Xiaomi Redmi A1+, but the leap in overall experience is well worth the extra investment. The 120Hz AMOLED display is noticeably smoother and more vibrant, the Snapdragon 888 processor can handle anything I throw at it, and the camera system lets me capture high-quality photos and videos without any issues. These advantages add up to a much more satisfying and enjoyable daily usage experience, which is what I value most. While the A1+ is a great budget option, it simply doesn't compare in terms of functionality. For me, the S21 FE offers the performance and experience I value.
