  2. What's your budget? If you need a budget-friendly option, the A05s is the way to go. If you are willing to spend more for a better experience, the S21 FE delivers on it.
  3. How much do you value display quality, camera quality and extra features? The S21 FE has a much better display (with AMOLED, higher brightness, and a higher refresh rate), better cameras (with OIS and more versatility), wireless charging and a larger array of sensors. If these are valuable features for you, the S21 FE is better suited for you.

Scenario-Based Recommendations:

Which Phone Would I Choose?

Personally, I would go for the Samsung Galaxy S21 FE 5G. While it might be older, and it comes with a premium price tag compared to the A05s, the sheer leap in performance, display quality, camera capabilities and wireless charging capabilities makes it a much more compelling device for me. As someone who appreciates a smooth user experience, good image quality, and enjoys mobile gaming on the side, the S21 FE is much better suited for my needs. The superior AMOLED display, combined with the advanced camera system and powerful chipset, provides the best possible experience. The additional sensors, better sound system, and wireless charging are features I find valuable and use on a daily basis, so it's an easy choice to make. While the A05s has great value for a budget phone, its limitations are too significant for a power user like me. The S21 FE’s capabilities justify the premium.

Ultimately, the "better" phone depends on your needs and priorities. If you just need a cheap phone that can last you a long time and you don't require advanced features, the A05s is a great option. However, for those who want a smoother experience and better features, the S21 FE is the better choice.
