For a long time I’ve used the usage data from my Audiobooks
app as a indication of what typical iOS usage looks like. It is an
old enough app with a wide enough userbase that its data has
generally been pretty reflective of what I see reported overall.
So while not perfect they should give a good general idea of what
customer choices. […]
So amongst customers with 16 GB devices 37% of them have less than
1 GB of space available, compared to just 1% with 64 GB [devices].
I’d say it is pretty fair to say that if you have less than 1GB of
data available on your iPhone you are in imminent danger of
running out and ruining your day. Taking the 43% of customers with
these devices and the 37% of them who fall in that range we have
17% of customers walking around each day with a damoclean
sword dangling over their heads.
Apple surely has better data, but according to Smith’s numbers, one out of six iPhone 6 users have less than 1 GB of free space.
