How does Apple's mobile phone transmit data to the new mobile phone?

1. Use Apple's own iCloud synchronization service for replication and synchronization. Just sign in to iCloud in the settings of your old phone, then check all options, and then sign in to the same Apple ID account in iCloud on your new iphone.

2. If the network conditions are not good, you can use a third-party transmission tool. Both iphone download software such as eggplant fast transmission or tooth fast transmission in Apple Store, and then select transmission according to the prompts.

First, use iTunes to transfer personal data to the new iPhone:

1. Open iTunes and find the "Device-Backup" command through the file drop-down menu. After clicking, iTunes will implement backup tools for personal data such as iPhone address books and memos. Connect the new iPhone device after the backup is completed, and then click "Restore from Backup" under the menu bar to transfer to the new iPhone.

2. Switch to the iPhone device management window. In the summary interface, you can choose to back up iPhone data to "iCloud", and then click the synchronization button in the lower right corner to realize the backup. In this way, you only need to log in with the same Apple ID account in the new iPhone settings, and then restore from the cloud iCloud backup.

Second, use the sync assistant to transfer personal data to the new iPhone:

1. In the Synchronization Assistant, you can perform a full backup like iTunes and then restore it to the new iPhone, or export a separate backup for each small project and then restore it to the new iPhone. For example, to make an overall backup, you can click the "Backup Recovery" function icon in the "More Functions" interface.

2. It is suggested that you can back up the SMS, camera pictures, contacts and other information of the original iPhone, and click the "Next" button to continue.

3. Click the Create Backup button at the top of the window that appears.

4. In the Create Backup dialog box, select New Backup for the first backup, set the save path, and then click the Backup button to start the backup. The second backup can be done by "incremental backup", which only backs up the newly added data, and the original data will not be backed up again, saving time.

5. After the backup is completed, return to the "Backup Recovery" window, under which the backed-up items will be displayed, and the specific backup time will be displayed for later selection. At this point, connect the new iPhone, re-enter the interface, select the corresponding backup file, and then click the "Restore from Backup" button to quickly transfer personal data to the new iPhone.
