What to check before buying outside China
- Confirm that Xiaomi or Redmi sells the exact model in your country and check the local price, warranty and availability; a global launch or current local retail listing is not established here.
- Check the supported network bands against your carrier before importing. Country-specific band compatibility is not established.
- Confirm the storage type and IP rating from the complete official specification for the exact regional model, since secondary listings differ.
- Compare the display, chipset, memory configuration, battery capacity, charging rates, cooling design and camera configuration as specifications only; these figures do not establish comparative performance, endurance, thermals or image quality.
Xiaomi’s official product page is available here, but the accessible page does not provide a readable detailed specification table to resolve the discrepancies above.
