While the Xiaomi Redmi 10 5G offers a larger battery and a more budget-friendly price, the Samsung Galaxy S21 5G provides a far superior overall user experience. The vastly superior performance due to the Exynos 2100 chipset makes a real difference in daily use, especially when multitasking and running more demanding apps or playing high end games. The AMOLED display, with its 120Hz refresh rate and high brightness, provides a much more enjoyable experience when viewing media.

The inclusion of wireless charging and superior build quality is an additional benefit.
While the larger battery of the Redmi 10 5G is appealing, the performance hit in other areas outweighs this. Given the choice, I would prioritize the significantly better screen, camera and performance of the Samsung Galaxy S21 5G, over the larger battery and lower price of the Xiaomi Redmi 10 5G. I am an enthusiast who would much rather have a better experience in everyday use over saving on cost.
