• Scenario 3: If you use your phone for photography, watching a lot of videos, and want a phone that is more performant and has a premium feel: Choose the Samsung Galaxy S21 5G.

My Choice

If I had to choose between these two phones, I would choose the Samsung Galaxy S21 5G. While the Xiaomi Redmi 13 has a larger battery and newer Android version, the Galaxy S21 5G wins on almost every other important aspect. The superior display with AMOLED technology and a 120Hz refresh rate alone makes a huge difference in daily usage, making content appear clearer, more vibrant and making the phone feel much more responsive. The powerful chipset also offers a much more fluid experience overall. The additional camera capabilities such as the zoom lens and the wide angle lens, and better video quality are also a great selling point.

While the S21 5G may be older, it’s better for gaming, content creation, and everyday tasks. It offers a more premium experience overall. Though the battery life might be shorter, the benefits in performance, display, camera, build quality and extra features outweigh this trade off. The wireless charging capabilities also come in handy in certain situations. While the Xiaomi Redmi 13 may be appealing for those on a very tight budget, the Samsung Galaxy S21 5G delivers a better user experience overall and far more value for the slight price difference.
