Why does my Apple phone backup always fail?

Automatic cloud backup using icloud requires four conditions:

1. If you have an Apple account, open the contents to be backed up in Settings -icloud and open Settings -icloud- Storage and Backup -I Cloud Cloud Backup. I bought my mobile phone in official website, so it is the account of apple store. Icloud's account and Apple's account are one;

2. the 2.iphone is connected to the power supply, that is, it is connected to the power supply through the charger;

3, lock the screen, that is, press the power button, black screen state;

4. Connect the wireless local area network, namely WIFI.

Only when these four conditions are met can automatic backup be performed.

Manual steps for using icloud: Go to "Settings -I cloud- Save and Back Up-Back Up Now" to back up iPhone information manually.

ICloud recovery data

The operation steps are as follows:

1. Connect the mobile phone to the computer and open ituns；;

2. Select "Device-iphone of XX-Version-Restore" and prompt "Do you want to back up the settings of iPhone before updating the software?". This should be the backup of ituns, which does not affect the cloud backup, and is determined according to personal needs;

3. Prompt "Are you sure you want to restore the iphone to factory settings? This will erase all your media and other data. In this case, the audio and video files are backed up in the computer, and it is the address book that needs to be restored urgently, so I chose "restore";

At this time, it takes about ten minutes to half an hour for ituns to download the system again. Don't unplug the data cable of the mobile phone all the time. After the download is completed, the initial setting interface appears on the mobile phone.

5. Follow the prompts one by one until "New iphone", "icloud Backup" and "ituns Backup" appear, and select "icloud Backup-Earlier Backup". At this time, the last three backup records appear, so choose one time when the mobile phone works normally to restore, and the rest wait;

6. The recovery was very successful, and no data was lost in photos, address books and software.
