What is the other category on my iPhone storage?

When I connect my iPhone to my computer I see nearly 5.0GB of "other" in the storage. I only have a 16 GB iPhone so it's clearly a problem. What is this "other" and how can I fix the issue?

Probably files inside your iPhone. The files that run the system and such maybe that's it.

Temp files, cache, downloads, game data, etc. You can clear the files in the other category if you restore your phone.

  • What's with the Other: Category on my iPhone? Everytime I plug it into iTunes it goes up a little.yesterrday it was at 0.95 MB now its at 1.01 GB. Is there a way to make it go down other then having it restored? And also what makes up the "other" category on the iPhone?
  • What to do about my iphone storage saying I'm using up way more photo storage than I actually am? My storage says I have 132 photos that's using up most of my storage; almost 3 GB. I have only 52 photos and 15 videos in my phone. It seems like it may be using storage from pictures I deleted, but apparently they're still using space? ? Has this happened to anyone else. I've taken my phone to an apple store, and I didn't get any answers.
  • What is in the Other category on my iPhone storage? I have an iPhone 4 (not 4s), and when i plug it into my computer, it says there's 3.5gb of Other, but i don't know what's in this "Other" category. I cleared all my web history/cache/cookies, and deleted tons and tons of emails along with all my text conversations and recent calls, but that barely did anything. What else can i do to reduce the size of this category?
