1, click iPhone Settings-General-Dosage.

2. Wait a few seconds (or 10 seconds), and all the applications and the space occupied by each application will be listed on the screen.

3. If you find that some applications occupy a lot of space (such as some games), but don't use them often, you can click on the application directly, and there will be a big "Delete Application" button on the next page, just delete it directly.

4. In addition, you may find that some applications "documents and data" will take up a lot of space, but the application size will not.

In this case, it is often created by an application, and some things will take up space. For example, the space occupied by the Camera ++ application in the mobile phone is actually the photos taken through this application. Just go directly to the application and delete the photos.
