iPhone 16 GB = 9.5 GB Actual
I just did a complete reset of my 6S to factory settings and have found upon checking available storage immediately after wiping, that 5.5 GB of my 16 GB phone is taken up by "System" storage (known elsewhere as "Other" storage).
I would like someone from Apple to confirm that it is expected (and accepted) that a phone marketed as having 16 GB of space, in fact only offers 9.5 GB of space when running iOS.
