What is wrong with iPhone storage?

I'm only getting to use 1.923gb of storage of my 16gb I have no music at all, about 100 pictures, almost no messages, 20 emails which they all get deleted daily. I only use my iPhone for games and the occasional few other things. I added up everything in my storage to get 1.923gb including the available that was left over after I added everything else up. I don't know what is going on if iPhone just has that much stuff on it that it takes up almost all that storage. Any help at all would be nice.

So I've smashed my phone 3 times now, twice to the point it was unresponsive which is what happened the other night.
