Final Decision
If I had to choose between these two phones, I would choose the OnePlus 9.
Reasoning:
My primary use cases for a phone involve a smooth user experience, quick app loading, and high-quality photography, particularly in low-light scenarios. The OnePlus 9 excels in all of these areas with its significantly faster chipset, the 120Hz display, and the much more capable camera. While the Xiaomi Redmi Note 10S offers a larger battery and a lower price tag, those benefits do not outweigh the importance of the OnePlus 9's performance and display smoothness for me. Additionally, the 65W fast charging mitigates the battery capacity difference by allowing for quick top-ups. The better quality screen, wifi and bluetooth connectivity are a bonus.
Although I would find the macro capabilities of the Xiaomi useful, they are not a necessity and therefore I would favour a better overall camera.
Ultimately, while the Xiaomi Redmi Note 10S is a capable phone for a lower price point, the user experience and performance offered by the OnePlus 9 would be worth the higher cost to me.
