- Performance: As someone who uses their phone heavily for browsing, social media, and gaming, the Snapdragon 888 and 8GB of RAM would provide a smoother experience and be more future-proof.

The larger battery in the Redmi Note 9T does not outweigh the much better features and experience offered by the Xperia 5 III.
