The UnboxingTN Verdict

out of 100

The Xiaomi 12S combines strong performance, a capable 120Hz display and broad connectivity, but its modest battery and aging software limit its appeal.

What is good

  • Snapdragon 8+ Gen 1 delivers powerful processing.
  • 6.28-inch AMOLED display supports 120Hz, Dolby Vision and HDR10+.
  • 5G, Wi-Fi 6E, NFC and dual-SIM connectivity are well covered.

What is not

  • The 4500 mAh battery is modest for this category.
  • Android 12 with MIUI 13 feels dated.
  • IP53 protection is limited against dust and water.
