If your iPhone is no longer as quick as it used to be, you may need to check whether iPhone system storage is high. To see the details, go to “Settings”, “General” and “iPhone Storage”. After the calculation is finished, scroll all the way down to the button and then, you can see “System”.


How to Clear System storage on iPhone with iTunes

When it comes to iTunes, it’s often about backup and file transfer. But you know what, iTunes can also be used to shrink the size of system storage on your iPhone and it’s extremely easy.

The only things you need are a set of computer with the latest version of iTunes installed and a USB cable.

Now, let’s see how this trick works.

Step 1 Launch iTunes on the computer and connect your iPhone to it via a USB cable.

Step 2 Unlock your iPhone by entering the passcodes. If you have never connected your iPhone to this computer before, you will be prompted to trust this computer. When you see the notification on the display, tap on “Trust” to proceed.

Step 3 Leave the iPhone and the computer alone for several minutes during which you don’t need to do anything like syncing them.

Step 4 Disconnect them and go to the setting App again to see whether the size of the system storage is reduced.

We have no ideas why this trick works in most cases, but we’re pretty sure that when your iPhone is connected with iTunes, some sort of procedure is going on to remove extra cache, temp, and cookie files from system storage.
