4. Buying Decision Framework

To make the best choice for your needs, ask yourself:

  1. How important is size and weight to me? If you value a more compact, lightweight device, the Xiaomi 12X is the clear winner. If a large screen is important, the ROG Phone 6 might be a better choice.
  2. What are my primary use cases? If gaming and performance are paramount, the ROG Phone 6’s superior power and battery will be invaluable. If your needs are more general, the Xiaomi 12X will do fine.
  3. How much do I value battery life? If you need a device to last a full day or more with heavy usage, the ROG Phone 6’s larger battery is crucial. The Xiaomi 12X's battery will be sufficient for light to medium users.

What Would I Choose?

Personally, I would choose the Asus ROG Phone 6. Here's why:

As a tech journalist and someone who appreciates a device that can handle anything I throw at it, the ROG Phone 6's raw power and battery life are too compelling to pass up. While I understand the appeal of the Xiaomi 12X's compact design, my primary needs revolve around performance, running multiple apps, long gaming sessions, and working on the go.

The ROG Phone 6's enhanced display with the higher refresh rate and brighter screen, coupled with the extra battery features and better connectivity options, make it a better fit for my needs. The larger size doesn't bother me, as I tend to use my devices primarily at my desk or at home, and I'm willing to trade a little portability for the major performance gains. The audio enhancement and better microphones are also useful for my use.

Ultimately, the best phone depends on individual needs and preferences. If you are not a power user, the Xiaomi 12X will suffice. But for anyone needing the maximum performance available, the ROG Phone 6 is the better choice.
