IPhone says I don't have enough storage available to update?

Added (1). To make room I can delete items in Usage Settings. However, I only have 5 downloaded apps… Facebook, Hay Day, Pinterest, Messenger, and Alarm Clock.

Am I missing something or is my phone really that small? If nothing else how can I ignore the update? Like remove the "1" next to Settings.

I've heard that if you connect your phone to iTunes and do the update through your computer it takes up less storage.

Your 5 apps should take up very little storage space. Could your pictures/videos/other files be responsible?
