Solution 5. Clear your Cache
If you’re in a hurry, delete programmes, images, and videos to free up some space. If you’re in a pinch, deleting your web browser cache can also help. If you go this way, keep in mind that you will be signed out of websites.
If you’re using Safari, clear your cache by going to Settings > Safari > Clear History and Website Data.
