Personal Choice

If I were choosing between these two phones, I would personally go with the Xiaomi 12X.

Here's why:

As a tech journalist and analyst, I prioritize performance, camera quality, and display fidelity above all else. The 12X’s superior processor and GPU make it more versatile, handling everything from heavy multitasking to demanding games. The significantly better screen and camera quality also play a huge role in my decision. Although it has a smaller battery, the significantly faster charging allows me to use the phone to its full extent.

Ultimately, the "better" phone depends on the user. But for my specific use cases and priorities, the Xiaomi 12X takes the lead, showcasing the benefits of opting for a device that's a power-packed option over a generalist.
