While the Redmi Note 10 Pro offers a larger battery, faster charging, and a more versatile camera system, the sheer performance difference of the S21+ makes it a more compelling option.

The S21+ also has superior features like wireless charging, better screen protection, and enhanced connectivity options such as Wi-Fi 6. Additionally, the better video capabilities of the S21+ and more advanced Bluetooth features are key factors for me. I prefer a streamlined, focused camera experience over a versatile one, so the telephoto and main lenses on the S21+ are very appealing. I also prefer a more up-to-date experience, and the extended software support is also a big bonus.

For my personal usage, the extra cost of the S21+ is worth the performance and feature upgrade.
