My Choice and Why

If I were choosing between these two phones, I would pick the Samsung Galaxy S21 5G. Here’s why:

While the Xiaomi Redmi Note 13 Pro 4G has significant advantages in battery life, charging speed, and storage capacity, my personal use case leans heavily towards performance and camera quality. The S21 5G's Exynos 2100 chipset provides a much smoother experience for gaming, multitasking, and demanding applications, which are areas where I frequently use my phone. Additionally, I value the superior camera capabilities of the S21 5G, particularly the optical zoom and 8K video. While the newer version of Android on the Xiaomi is attractive, I am more concerned about the core performance for what I am using the device for. I am also very drawn to the additional benefits of wireless charging and reverse wireless charging.

The significantly better performance of the S21 5G coupled with its more advanced camera system outweigh the advantages that the Xiaomi offers for my specific needs. Therefore, I would pick the Samsung.
