My Choice
If I had to choose between these two, I would choose the Apple iPhone 15 Plus. While it is significantly more expensive, the vast difference in performance, display quality, and camera capabilities make it the clear winner. As someone who uses their phone for heavy daily use, and values the quality of both the screen and the camera I value, the better user experience of the iPhone far outweighs the price difference. The A16 Bionic chip ensures smooth performance, and the OLED display provides a superior visual experience. While the Redmi Note 9T offers a more affordable option and better battery, the compromises in other areas are too significant for my use case. However, for someone with a tighter budget who wants a functional phone for everyday tasks and don't care about having the best display/camera, the Redmi Note 9T is a practical option.
