No local storage space to update apps?

When I try to update my apps from my iPhone, it says there isn't enough local storage space. However, when I go on my computer I still have storage space left. Is there like a certain amount needed to update apps or what?

The update you are trying to download could be quite large. Consider deleting apps that you really don't use that much.

  • Why is my iPhone storage space used so high? I have a 16GB iPhone 4s. I have no songs or videos on it. I have about 32 apps and 500 pictures. My storage space used is at 13.2 GB. Why is that so high? That is almost all of my available data? How can I bring this down? I have a friend with the same phone, same number of pictures and about the same number of apps (maybe a few less) and his storage is only about 4GB used.
  • Why does my iPhone say that I have no storage space? I deleted so many apps and it still says that I have no space. I can't take pictures, download apps, nothing. I've tried turning it off and on and it says the same thing. What can I do to fix it? I'm trying to do everything I can't to restore it.
  • My iPhone suddenly went from having 9.4 gb of free space to 7.5 gb of free space? I didn't download any apps or anything, or record any videos or take pictures. I didn't do anything, it just all of a sudden happened today. How can I fix it? I have a 16gb iPhone 5
  • IPhone used space and available space are far from adding up? On my phone it says 12gb used space and 1.5gb available but I have a 16gb phone, while leaves a 2.5 gb space gap. Does iOS take up that much space on its own or is something wrong?
