4. Buying Decision Framework

Here are three questions to guide your decision:

  1. What is your priority for screen size and form factor? Do you prefer a standard compact phone (Xiaomi 12X), or a large, foldable display (Huawei Mate X3)?
  2. How important is the camera system, and do you need optical zoom or 8k recording? If optical zoom is a must, Mate X3 is your choice. For the highest video quality with 8k capabilities, the Xiaomi 12X is better.
  3. What is your typical usage and storage needs? For those that need a lot of storage and a large display, the Mate X3 should be considered. For everyday use, the Xiaomi 12X shines with its compactness.

Scenario-Based Recommendations:

  • The Minimalist: If you value a lightweight, easily pocketable device with a very bright screen for outdoor visibility, choose the Xiaomi 12X.
  • The Multitasker/Media Buff: If you need a large display for productivity and entertainment with top performance, you should choose the Mate X3.
  • The Mobile Photographer: If you value more lenses, especially telephoto for zoom photography, and wireless charging, the Mate X3 is for you. If you care about video quality, the Xiaomi 12X is the better option.

My Pick and Why

Given my preference for a device that balances performance, size, and camera versatility without compromising too much on the price, I would choose the Xiaomi 12X.

Here's why:

  • Practicality: Its compact size makes it easy to handle and carry around, which is important for me as a tech journalist always on the go.
  • Excellent Display: The AMOLED screen with 1100 nits is a joy to use. I work outdoors a lot, so a bright and clear display is very important for me.
  • Comprehensive Feature Set: The combination of a solid main camera, wide-angle lens, macro, and high-quality audio features, 8K video capabilities, makes it more than adequate for my everyday needs.
  • Price to performance: The price to performance ratio is amazing, I am able to get a great experience without paying a premium price.

While the Huawei Mate X3 is an impressive piece of engineering with its foldable design and cutting-edge performance, it is overkill for my needs. I prefer the practicality and balance the Xiaomi 12X offers for everyday use. If I needed to have a tablet like experience I would opt for an actual tablet rather than a smartphone/tablet hybrid.

I hope this in-depth analysis helps you make an informed decision!
