The storage version is not consistently reported: Gadgets 360 identifies UFS 4, while GSMArena specifies UFS 4.1. The available specifications do not resolve that difference, so neither version should be treated as definitive without confirmation from a complete official specification table.

Cooling fan and battery
The phone is reported to include a built-in active cooling fan. Gadgets 360 describes a Redmi claim that the fan can reduce temperature by approximately 10°C in 100 seconds. That figure is a reported brand claim, not an independent thermal test, and does not establish gaming performance or sustained temperatures.
