Here are three practical questions to help you decide:

My Choice

If I were choosing between these two devices, I would pick the Samsung Galaxy Z Flip3 5G. While it has the older release date and does not provide a great battery life, the sheer difference in performance, screen quality, and the versatility of the camera and the overall experience far outweighs the benefit of the Realme C51. Additionally, the folding factor offers a different smartphone experience.

The Realme C51 offers a great bang for the buck, but for me, the ability to play high-fidelity games, enjoy content on a great display, and capture more meaningful photographs and videos is essential. I am also a tech enthusiast and love the innovative design of the Z Flip3. The slightly weaker battery is a compromise I am willing to make for the rest of the package.
