The UnboxingTN Verdict

out of 100

The Xiaomi 12 delivers strong performance, capable cameras and excellent connectivity, but its modest battery and aging software hold back this compact flagship.

What is good

  • Snapdragon 8 Gen 1 and 12GB RAM provide strong performance.
  • 50MP OIS main camera and 2x telephoto support versatile photography.
  • 5G and Wi-Fi 6E deliver modern, fast connectivity.

What is not

  • The 4500mAh battery is modest for this performance-focused hardware.
  • Android 12 limits software longevity.
  • IP53 protection and USB-C 2.0 provide limited durability and transfer speeds.
