To import the data of the Mi 13 to the iPhone, you first need to back up the data in the Mi 13, which can be backed up using the backup function of the Xiaomi or third-party backup software.
Then, download and install a data transfer tool, such as the Move to iOS app, on your iPhone.
Open the app and follow the instructions to connect your Mi 13 to your iPhone, select the type of data you want to import, and then start transferring.
During transmission, make sure both phones are connected and fully charged.
After the transfer is completed, the data of the Mi 13 can be viewed and used on the iPhone. After data import is complete, backup data on the Mi 13 can be deleted to free up space.
