My Choice
If I had to choose between these two phones, I would choose the OnePlus 9 Pro. Here's why:
While the Xiaomi Redmi Note 12 has a good battery and an AMOLED screen, the OnePlus 9 Pro is superior in areas that are more critical for my use case. The Snapdragon 888 chip offers significantly more power for multitasking and resource-intensive applications, which I value. The vastly superior camera system, with its telephoto and wide-angle lenses, and ability to shoot higher-quality video, is very appealing for photography and content creation. Although battery life is slightly lower, the much faster charging speeds and wireless charging features offset this. Also, its slightly smaller size makes it a bit more comfortable for handling and its superior screen brightness is a must for better outdoor visibility. Finally, the newer Bluetooth and Wi-Fi technologies are a big plus.
