Final Thoughts: My Choice

If I were choosing between these two phones, I'd go with the Samsung Galaxy S21 FE 5G. While it is the older device and the battery isn't as big, the significant advantages in display quality, processing power, and camera capabilities are really important for me. As a tech journalist, I need a phone that can handle a variety of tasks from content creation to heavy usage, and the S21 FE is just better at everything. The sharper display makes a huge difference for day to day use and the 4K video is invaluable. The convenience of wireless charging is also something I use quite a lot.

While the Realme C65 is newer and has good value, it's too much of a compromise on overall performance, display, and camera for my needs. For users who primarily browse social media and need an affordable smartphone with reliable battery life, the C65 would be perfectly adequate. However, for a more demanding user like myself, the S21 FE's superior feature set and performance makes it well worth the cost, even though it's older. The S21 FE is the more "future-proof" and more aligned to my daily needs and my overall tech usage.
