The UnboxingTN Verdict

out of 100

A powerful Snapdragon 855 and vibrant AMOLED display remain appealing, but the small battery and aging Android 9 software limit this otherwise capable phone.

What is good

  • Snapdragon 855 delivers strong everyday performance.
  • 6.39-inch Super AMOLED display is vibrant and sharp.
  • Up to 256GB storage offers useful capacity.

What is not

  • 4000 mAh battery is a clear weakness.
  • Android 9.0 and MIUI 11 feel dated.
  • The 191g body feels relatively heavy.

How the score breaks down

  • Performance 65
  • Display 75
  • Battery 13
  • Connectivity 60
  • Build 63
  • Software 34
