But Bob has suggested that MOST of 11.56 GB is used by iOS on his phone...definitely neither "normal" nor even "reasonable".
That is correct. In fact, since my last post, the Free memory has now dropped to 643.3MB and the Used memory is up to 12.16GB, with no new apps installed.
It seems that after deleting a bunch of things, much of the memory didn't really get freed up. I deleted all of my email messages, and the memory usage of the Mail app never changed.
I'll have a look at the Cleaner and File Manager apps and see what they can do. Though, I have a feeling that the simplest fix will be to reset back to factory settings. I don't have anything on the phone that hasn't been backed up anyway.
