  2. What do you value most in a display? If you want a vibrant screen with great outdoor visibility, the AMOLED on the S21 FE is significantly better.
  3. What is your budget and what do you value most? If you prioritize the latest android and longer battery life on a budget the Poco M6 is a better option

Scenario-Based Recommendations:

  • Gaming: The S21 FE, with its Snapdragon 888 and better GPU, will provide a smoother, more enjoyable gaming experience.

Personal Choice

If I were choosing between these two, I'd go with the Samsung Galaxy S21 FE 5G. While it's older and might not have the absolute latest Android version out of the box, the combination of the superior AMOLED display, significantly more powerful processor, and versatile camera system makes it a better all-around package for my needs. The wireless charging and better build quality are just added perks. I often find myself using my phone for resource intensive tasks and value a display that looks great in any condition. While the Poco M6 is a fine budget option, the sacrifices in performance, display, and camera quality are significant and not something I'd be willing to trade.
