The UnboxingTN Verdict

out of 100

The Redmi K20 pairs a vivid AMOLED display and capable cameras with aging software and disappointing battery endurance.

What is good

  • 48 MP triple-camera system provides versatile photography.
  • Snapdragon 730 and 8 GB RAM support smooth everyday performance.

What is not

  • 4000 mAh battery delivers disappointing endurance.
  • Android 9 software, upgradeable only to Android 10, feels outdated.
  • USB 2.0 limits wired data-transfer speeds.
