Clearing app cache?

I noticed that certain apps, like Facebook, Pinterest and Instagram, are starting to hog up a bunch of memory on my device. When checking the usage details, I don't have the option to clear out the 'documents & data' within the app. I've been reading a few things online which advised that deleting and reinstalling the app is the only way to clear it out on the phone. It seems to be a bit of an inconvenience, especially if I use the apps often and they start accumulating new data all over again after they are reinstalled. Any suggestions or tips? Thanks! 🙂

iPhone 4, iOS 5.1

Can I jump in here?

I have the same problem.

Facebook has 90mb cached, but Real Racing 3 which is a 22mb app, has 1.3GB cached!!

I hardly use the game, but don't want rid of it.


How do I clear that large cache then? If I uninstall it uninstalls and deletes all data so I use my way in the game.


Dropbox is the same. 350mb of data and I don't see how to clear it.

If I unlink, and then link again, does it then go to try to add my pics again?

It's indeed odd that Apple doesn't come up with a solution (let's hope in the next iOS update) where it automatically clears this cache for all apps to have more storage space. Or that you can delete this cache per app within Settings or directly in the settings of an app (which is possible in some apps already).


I hated that i needed to do this on Android because the phone became too slow. In the case of my iPhone it isn't a matter of speed but storage space which is used up.
