My Choice
If I were choosing between these two phones, I would choose the Samsung Galaxy S21 5G.
Explanation:
My primary use case involves heavy multitasking, mobile gaming, and photography. The S21's superior performance with the Exynos 2100 chipset is crucial for smooth operation and seamless gaming experiences. The AMOLED display with 120Hz is a major advantage, providing a much more enjoyable viewing experience when watching videos and browsing content. The S21 camera system, with its telephoto lens and high-quality video recording, fits well with my desire for good camera performance. While the S21's battery is smaller than the Xiaomi's, the enhanced charging capabilities (25W wired and 15W wireless) and overall power efficiency of the chipset are acceptable trade-offs. I also value build quality and better protection for the display, the superior screen protection is a plus. Although the price is higher than the Xiaomi, the premium features are well worth the investment for my specific needs.
While the Xiaomi Redmi 10 is a good budget device, the gap in performance and screen quality makes it a less suitable option for my use case. The inclusion of the wide and macro lens are appealing; however, the overall camera performance is lower. The larger battery capacity is a good feature; however, the significantly slower processor and lower quality screen make this a compromise I am unwilling to make. Therefore, I value the Samsung Galaxy S21 5G's performance and display capabilities significantly more than the Xiaomi’s advantages.
