I have a 32 GB iPhone, but the actual usable capacity is 29.33 GB, or 91.6%
You're confusing decimal math with binary math.
In binary notation, your 32gb iPhone has 32,000,000,000 bytes. In decimal math, one gigabyte is 1024x1024x1024 (1,073,741,824 bytes). Divide 32,000,000,000 by 1,073,741,824 and you're answer is 29.8gb of usable capacity in the decimal system. You have not lost 9.4% of your capacity.
