iPad usage does not seem accurate I have a 16GB iPad Air 2. I realize the OS takes up some space (on my iPad, "Used" + "Available" only equals 11.9GB), but looking at this screenshot, even my iPad can't accurately explain what's taking up 8.2 GB. I know it's not the OS because Used + Available is already lower than 16. And I added up all the apps underneath and only came to a little under 800MB. What on earth is taking up the remaining 7.5GB?!



My drawing to illustrate my question:
These could be some temporary files - usually, after a restart they get deleted freeing precious space.

When you connect iOS device to iTunes, these often show as "other" in Summary tab.
