I just did this. There is a good article on it here: http://www.kare11.com/story/tech/2015/02/24/tips-to-increase-the-storage-on-your-iphone/23956123/ I learned that my HDR photos were taking up a bunch of space and I also had wayyyy too many old text messages saved with my family group chats and BFFs. Your phone saves all of these indefinitely by default so I would start with swiping left on the "messages" menu on any long text message chains and pressing "delete". That and deleting photos I had taken 3 different versions of freed up a lot of my space.
