What is other in iPhone usage on iTunes?

I have a 16gb iPhone 5s and recently 2.48 gbs of "other" has been added to my memory capacity on my phone. I've had my phone for only 2 months and i'm down to 4gb, so those extra 2gbs would be lovely to have back; but i don't know how to clear it? If anyone knows how to free up the extra space it would be much appreciated!

Well you can't gt it back. It problyy a Itunes updat or apps

Album art your Music stores, cache data from mobile Safari/Chrome, cookies, text messages, Facebook data, Apps' data and caches etc. It's huge. And this huge thing is what clogs up space in the form of "Other" data.

If you want to get rid of this "Other" data, here is detailed guide to help you
