Getting an iTunes error “iTunes Could Not Backup / Restore iPhone Because the iPhone Disconnected” while restoring or backing up iDevices means that the backup or restore process stopped when iTunes did NOT expect it to. This message occurs while restoring or backing up iDevices (iPhone, iPad, iPod Touch) running all iOS versions. The cause of this problem may be different. It depends on various factors like the lightning cable, USB port used, or backup files. That’s why there are different ways how to fix it. In this article, we will focus on providing all the working solutions for fixing this error. Now jump down to the next section and start troubleshooting.
Before trying the first method, you need to do the following things.
- Check if you are using the original (or MFi-certified) USB lightning cable.
- Make sure your iDevice is connected to the computer.
- Make sure you’re not using a jailbroken iDevice.

Try using another USB cable while backing up your iDevice. Make sure it an MFi-certified one. (You can borrow one from your family members or friends to try out.)
iTunes Could Not Backup/Restore Fix #2
Remove any USB hubs (or keyboard with USB slots) between your iDevice and your computer. (Connect your USB cable directly to your computer).
iTunes Could Not Backup/Restore Fix #3
Try switching the USB ports on the computer. One of them may be the problem.
iTunes Could Not Backup/Restore Fix #4
Restart the computer you are using for the restore. This will fix the potential USB connection failures.

Reset your iDevice’s Network Settings. Open Settings and go to General > Reset > Reset Network Settings. Resetting these settings will NOT delete any data from your iDevice. However, it will remove the network settings (Wi-Fi passwords and adjustments).

Turn OFF Background App Refresh on your iDevice. Go to Settings > General > Background App Refresh > OFF. (Do not forget to turn it back on after you finish with the backup procedure.)
