More free RAM after a Restore

[sliberty]

I had a problem with my iPad Mini. A Magazine that I read using Bookshelf became corrupt during an update. I couldn't fix it or delete it, so I decided on brute force. I did a Backup / Restore, and the Magazine is fixed now (YEA!). What surprised me though is that I have 10GB more free space than I did before the Backup / Restore. All of my apps, photos and music are back in place, so what caused extra free space? Is there app data missing that I don't know about yet? Or is this just a case of garbage collection?

Some apps are prone to cache a lot of data, FaceBook is notorious for this, and the only way to get rid of the data is to delete the app in question and reinstall it. A full restore of the iPad did the same for every app on your iPad.

So will all that caching be visible in the space usage numbers? Just wondering how to know which apps might be the ones needing maint....

If you look at the apps in the usage list I mentioned in my previous post, the size of the app and the size of the cached data are both present.
