Third-party reviews

What customers like about Xiaomi Redmi K20 (8GB + 256GB)

  • Stunning full-screen AMOLED display with no notch, offering immersive viewing experience and vivid colors.
  • Sleek, stylish design and premium, solid build quality with Gorilla Glass 5 on front and back.
  • Great battery life, easily lasting a full day or more with moderate usage.
  • Lag-free and smooth performance for daily tasks and gaming, thanks to the Snapdragon 730 processor.
  • Impressive camera hardware and good photo quality in well-lit conditions, with the flexibility of a triple-lens setup (wide, ultra-wide, telephoto).
  • The inclusion of a 3.5mm headphone jack is appreciated by users.
  • Fast and accurate in-display fingerprint sensor.
  • Comes with useful in-box accessories like a hard protective case and an 18W fast charger.

What customers don't like about Xiaomi Redmi K20 (8GB + 256GB)

  • No expandable storage (no microSD card slot), which is a significant drawback for some users.
  • Underwhelming camera performance in low-light conditions, often lacking detail and colors.
  • The motorized pop-up camera, while enabling the full-screen display, can be a nuance, making face unlock slow and potentially feeling less durable over time.
  • The phone is quite slippery due to the glass back and prone to smudges.
  • The software (MIUI) includes ads and some minor bugs/glitches, which can be a major con for some users.
  • Lack of stereo speakers (it has a single mono speaker).
  • Does not support 4K video recording at 60fps.
  • No official IP rating for water or dust resistance.

Verdict

The Xiaomi Redmi K20 (8GB + 256GB variant) is a compelling former flagship killer, notable for its immersive, uninterrupted 6.39-inch Full HD+ AMOLED display thanks to a unique pop-up 20MP selfie camera. It is powered by the capable Qualcomm Snapdragon 730 processor, paired with a generous 8GB of RAM and 256GB of non-expandable internal storage, offering smooth performance and ample space. A versatile 48MP triple-rear camera system captures detailed photos, while the substantial 4,000mAh battery supports 18W fast charging for all-day use. Key pros include the edge-to-edge screen, premium glass build, and the inclusion of a 3.5mm headphone jack and in-display fingerprint sensor; however, cons involve the lack of official IP water resistance and the absence of OIS (Optical Image Stabilization) on the camera system.
