I have an IPad 2. I have 9.2GB of 57gb capacity How do I delete things to increase storage?

Hi. You can see which apps are using storage this way:

Go to Settings > General > Storage & iCloud Usage > STORAGE Manage Storage. Note that this is the first Manage Storage. Wait for the list to populate and tap on the entry for the app. You can delete an app directly from there and it will remove all its data. Otherwise, you can enter the app and use its controls to remove individual files. You can clean out Safari data under Settings > Safari. For Chrome, it's under the ... menu in the app. You can delete a mail account to remove the data for that account.

Delete any apps you no longer need or or use infrequently.

Thin out delete any stored music, movies and video.

Thin out/delete images/photos from the Photos app.

Thin out/delete emails.

Thin out/delete any saved iBooks, PDFs stored in iBooks or any other eBooks or eMagazines.

Good Luck!
