Solution 1: Connect your device to iTunes, backup, and then restore.

Our friends at the Apple Genius Bar gave us advice that sometimes our device stores our data until we backup our phones. To test this theory out, we have backed up our device and restored it after the iOS 12.4 update. We noticed a significant amount of storage space reduction and our phone was soft rebooted during the process.

Solution 2: Restart your device by holding the Power button or going to General > Shut Down then sliding the button to confirm.

One your device powers down, let it sit for 30-60 seconds. You may power back up your device by holding onto the Power button until the Apple logo appears on your screen. As a reminder, this is considered a soft reboot and you will not lose your data on your device when this is done properly.

Solution 3: Allow the device to connect to iCloud automatically.

To allow iCloud to start this process, your device must be plugged into a power source, connected to a stable Wi-Fi connection, and locked. Once your device detects all three statuses, it will connect to your iCloud account to back itself up.

Solution 4: Leave the device to self-maintain.


The iOS platform has self-management processes and usually will resolve almost all issues on its own. If you go with this solution, you should see that in approximately 4-7 days that the phone self-maintains without you taking action.
