Why is 'other' on my iphone and why is it taking up so much?

When I sync my iphone on my mac it shows me what's being used at the bottom in a bar (music, apps, photos, other). My 'other' is taking up 2/3 of the bar and I don't know what that data is from? What do I do to make that 'other' bar go down so that I can free up some room on my phone

Its data from apps like games saves

  • Why is the Other data taking up 5 GB in my iphone? I have 1 picture and 4 apps. I continuously have to delete everything because I have only less than 3 GB for everything. I did everything to deleting cookies to resetting my iPhone but it isn't working.
  • Why is other taking up so much space on my iPhone? - 1 And more importantly, what can I get rid of to get more space? I've deleted texts, calls, voicemails, emails, photos, songs, safari cookies & data, AND notes. What is going on? It's taking up around 3 GBs (or whatever) and it's killing me.
  • Why is other taking up 6.8 of my memory space on my iphone 5? On my iphone 5 "other" is taking up 6.8 of my data… What is this other and how do i reclaim my space? I've tried like resetting my phone and rebacking it up and stuff but nothing happened…
  • Why is other taking up 3.32 GB on my iphone? What is it? I got no calendar events. No reminders. Hardly any texts messages. No apps. No notes. No photos. No music. No "world clock". I have one alarm for when I get up in the morning. I literally have nothing on my phone, since I just updated it to iOS 7.0.4. Is there anything I can do to get rid of all this "other"?
