How does Apple 6 clean the disk?

1, using the Dose option.

Open settings-> General->; Dose. The list shows the storage space occupied by each project. Click the button on the right side of the list to see the details, where you can delete some unnecessary items.

2. View other iTunes projects.

The category that takes up the most space here is "Other", including cache, backup, some downloaded files and some data of iOS 7 built-in applications, such as SMS and email. Select useless delete.

3. Delete the Web browser cache:

Open the settings, click the Safari button, and then click Clear History and Clear Cookie and Data.

4. Delete mail:

You can delete a message or an entire conversation. Usually, some short messages will contain some pictures, audio or video files, and some space will be recovered after deletion.

5. Delete the email attachment:

Set up mail, address book, calendar iCloud, then scroll down to the end and click Delete Account. Delete it and then add it back.
