  2. How much do you prioritize performance and storage? If you plan on heavy multitasking and gaming, the Redmi 12's slightly better chip and storage options will be beneficial.
  3. How do you prioritize battery charging speed? The Redmi 12 is a better choice if quick charge-ups are a priority.

My Choice and Why

If I were choosing between these two devices for myself, I would lean towards the Xiaomi Redmi 12. As a tech enthusiast who’s constantly jumping between apps and occasionally needs a burst of power for light gaming, the smoother 90Hz display and better performance edge it out. The faster charging is a huge plus for my on-the-go lifestyle. While I appreciate the Motorola's AMOLED display and advanced camera features, I find the Redmi’s overall balance of modern features more compelling for my needs. Furthermore, I do prefer a bigger screen and don't mind the added weight. The Android 13 is just icing on the cake.
