Disadvantages of Xiaomi Redmi 9

  • The device is relatively heavy, weighing 198g, which might be uncomfortable for some users.
  • The build quality consists of a plastic back and frame, which may not feel as premium as devices with metal or glass bodies.
  • The IPS LCD screen, while decent, lacks the vibrant colors and contrasts of AMOLED displays.
  • The charging speed, limited to 18W, might be considered slow compared to devices with faster-charging capabilities.
  • The main camera setup, although a quad configuration, lacks higher resolution sensors that are common in more recent devices.
  • The processor, MediaTek Helio G80, may not perform as efficiently with resource-intensive apps compared to more advanced processors.
  • Limited video capabilities, with recording maxed at 1080p@30fps, missing out on 4K video support.
  • Market-dependent NFC availability can be inconvenient for users relying on contactless payment.
