4. Buying Decision Framework

Here are three questions to help you choose:

  1. Performance or Novelty? Do you prioritize top-tier performance and camera quality above all else (Xiaomi 12), or does the compact and stylish foldable design of the Razr 40 appeal to you more?
  2. Screen Quality or Size? Do you prefer a high-quality, vibrant AMOLED display (Xiaomi 12) or a larger, brighter screen with a higher refresh rate (Razr 40)?
  3. Daily Use? Do you need a phone that charges quickly and excels in demanding tasks, or are you looking for a phone that is stylish, compact, and just meets basic needs?

Final Recommendation

It provides a flagship experience with top-of-the-line processing, camera quality, and a vibrant AMOLED display. It’s the right choice for power users and those who value performance above all.

However, if you're drawn to the unique form factor of a foldable phone, appreciate the larger screen for media consumption, and are willing to compromise on raw performance and camera quality for the sake of portability, the Motorola Razr 40 is a compelling choice. It offers a modern design, compact form factor when folded, and a solid experience for daily use, especially for style-conscious users.

My Choice

For me, I'd choose the Xiaomi 12 without hesitation. As a tech journalist who loves a smooth experience and appreciates a powerful camera, the Snapdragon 8 Gen 1 and the superb Sony IMX766 sensor are too good to pass up. While the foldable design of the Razr 40 is cool, I prefer raw performance, superior camera quality and a great display for my daily work and personal use. The Xiaomi 12 fits my needs perfectly, and it's hard to argue with the value it offers for the price.
