If the update doesn't complete

If you're installing the update, the progress bar might appear to move slowly. The time an update takes depends on the size of the update and the number of files on your device.

When you're updating over the air, keep your device connected to a power source. If your device runs out of power, connect it to a power source and turn on the device to let the update or restore complete.

Learn what to do if your iPhone or iPad appears frozen or won't start.

Let us know if that's able to help.

Have a great day!
