4. Buying Decision Framework
Here are three questions to help guide the buying decision:
- How important is performance to you? If you need smooth multitasking, gaming, and a fast experience, the S21 FE 5G is the only choice. The Redmi A3 will feel slow in comparison.
- What is your budget? The A3 is far more budget-friendly, but you will be sacrificing almost all features and performance.
- What will you be using your phone for? The A3 suffices for basic use, but if you plan on doing any content creation, gaming, or general multitasking, the S21 FE 5G is miles ahead.
Scenario-Based Recommendations:
- For the Power User: If you are a power user who values high performance, premium display, excellent camera, and extra features, choose the Samsung Galaxy S21 FE 5G.
- For the Casual User: If budget is your primary concern and you use your phone for basic tasks, the Xiaomi Redmi A3 may suffice.
- For the User on a Budget who still Wants More: If you have some room in the budget, the Samsung Galaxy S21 FE 5G is significantly better and will last much longer and provide a vastly better experience.
My Choice
If it were up to me, I would choose the Samsung Galaxy S21 FE 5G. Although it is an older phone, it is still very competitive. The superior display alone is enough to win me over, but combined with the flagship processor, outstanding camera capabilities, much faster charging, wireless charging, reverse wireless charging, great audio, and more advanced features, it is a far more complete package and much better experience overall. The extra investment is more than worth it for the vastly superior experience, as it will be smooth, responsive, and will not leave you wanting for more. While the Xiaomi Redmi A3 is certainly more affordable, it sacrifices far too many key areas. The user experience will feel slower and lackluster, and the features are very basic, and will likely feel dated very quickly. For anyone who relies on their phone for anything beyond very basic calls and texts, the S21 FE 5G is the better option by a large margin.
