My Choice
If I had to choose between these two phones, I would personally choose the OnePlus 9. While the Xiaomi 11T Pro has a larger battery and much faster charging, I find the smaller size of the OnePlus 9 more appealing for everyday use. The superior wide-angle camera is a significant factor for me as I enjoy taking landscape shots, and having wireless charging gives me more flexibility. Although Xiaomi provides the benefits of an extra macro lens and better screen protection, I feel these features are outweighed by my personal preferences of compactness, camera quality, and wireless charging.
