The dirty little not-so-secret of smartphones is that you'll never get the full amount of memory marked on the case. Operating systems take up space! But different phones leave you with different amounts of storage. Here, from Which?, are the most and least generous.

Among 16GB smartphones, the iPhone 5C ends up leaving the most space open for the user at 79%. Bottom of the barrel? Samsung's Galaxy S4, which is so loaded down with bloatware that only 54% of the 16GB promised is actually there. Head on over to Which? for analysis on what's going on with each phone, and remember: the number on the box ain't always the number you get. [Which? via AppleInsider]
