My Choice

If I were choosing between these two phones, I would pick the iPhone 12 Pro Max. Although the Realme 9i offers a larger battery and faster charging, the iPhone's superiority in performance, display quality, and camera versatility significantly outweighs these advantages for my needs. I value a smooth and fast user experience, and I heavily rely on the camera capabilities of my phone for both personal and professional use. The premium build quality and access to Apple's ecosystem also appeal to me. While the higher cost is a drawback, the overall quality and longevity make it a worthwhile investment, for me. However, I acknowledge that for many users, the Realme 9i offers a more than adequate experience at a far more affordable price.
