Price

Criticism

The Poco X3 Pro and maybe the Poco X3 NFC had a faulty PMIC, which eventually caused the phone to not charge and the memory chip to corrupt, rendering the phone bricked, as you need an authorized Mi account to flash using EDL. Unlike popular belief it affected both the Indian and the EEA variants. A temporary fix was rebooting the phone into fastboot, which caused a "recalibration" of the PMIC. Xiaomi confirmed the issue and gave another 6 months of warranty to the Indian version.

Lot of screens were defect, which caused ghost touch issues and random wake-ups. Sometimes it corresponded with a PMIC failure which caused some to believe that the PMIC caused these issues, although Xiaomi has not acknowledged it.
