How to track the exact location when Apple's mobile phone is lost and turned off?

If Apple's mobile phone is lost and turned off, you can try the following methods to track its exact location:

1. Use the "Find My iPhone" function: log in to iCloud official website, enter the account number and password of the lost device in "Find My iPhone", and locate the device after completing double authentication.

2. Positioning through another Apple phone: You can locate by looking up my iPhone function. Turn on the function of finding my iPhone on another Apple phone, enter the login account and password of the lost phone to log in, and you can locate the lost phone.

3. Positioning through Apple's after-sales service center: If the "Find My iPhone" function is not enabled for your lost mobile phone, you can contact Apple's after-sales service center for positioning.
