Here are three practical questions to help users decide:

  1. How important is peak performance and fast charging? If top-tier speed and super-fast charging are essential, the Xiaomi 12 Pro is the better choice.
  2. What are your priorities for the display? If you want the highest possible sharpness and brightness, the Xiaomi 12 Pro's display is significantly superior.

Conclusion

The Xiaomi 12 Pro is clearly the superior phone in terms of performance, display, camera, and charging capabilities. The only advantage of the Samsung is the slightly lighter design and macro lens, which is not a crucial thing for most people.

My Choice:

If I were in the market for a new phone today, I would choose the Xiaomi 12 Pro without hesitation. Here's why:

  • Performance is King: As someone who constantly uses my phone for heavy multitasking, research, and content consumption, the Snapdragon 8 Gen 1 is essential. I need the extra power for demanding apps and games, and the 12 Pro delivers that in spades.
  • Display Matters: The sharper, brighter display is a must-have for me. I spend a lot of time reading articles, watching videos, and reviewing images, so I can't compromise on quality.
  • Camera Versatility: I often find myself needing a dependable camera for both work and personal projects. The Xiaomi's high-resolution sensors, wide-angle capabilities, and 8K video are invaluable.
  • Speedy Charging: As a very busy tech journalist, I constantly use my phone, so the 120W fast charging is a godsend!

While the Samsung Galaxy M55 is a solid option for budget-conscious users, it simply doesn't offer the same level of experience in performance, display and camera quality that I need for my daily requirements. The Xiaomi 12 Pro may be the older phone, but it is still a phenomenal all-around device.

I hope this helps! Let me know if you have any further questions.
