The new flagships Xiaomi 14 and Xiaomi 14 Pro implement UltraSpace technology, which gives users more space to store files (e.g. photos and videos). Yes, the 256GB units actually have 264GB of flash memory, and the 512GB version has 528GB available.

How is it applied? Each flash memory chip has a dedicated area for Overprovisioning functions to increase memory speed and reliability. It performs Overprovisioning, Garbage Collection, Wear Leveling, and Bad Block Remapping. For Overprovisioning, 10 GB is reserved in the memory chip, so the real volume of such a chip with the declared 256 GB is 266 GB. Xiaomi engineers found a way to use the volume reserved for Overprovisioning without compromising the reliability or speed of the drive.

It is worth noting that UltraSpace is only available on HyperOS smartphones, but it is known that most existing MIUI devices will get HyperOS next year. Later, according to the idea, UltraSpace will be available in these models as well.
