Q: 64gb actual capacity
Just got the new iPhone 64gb in size, and while i do realise that you never get the full capacity due to the operating system size, and other software on the phone etc, i don't understand why my last iPhone, which was 16gb in capacity actually had about 13gb to play with.
last iphone 5 = had 3gb missing.
New iPhone 6 = 8gb missing.
this can't be to do with iOS 8, because you don't lose that vast amount from updating to it on older devices.
Any thoughts on this?
Many thanks
iMac, OS X Mavericks (10.9.2)

Manufactures measure using 1000 MB per GB, but the actual conversion is 1024 MB per GB.
They consider 1 KB to consist of 1000 bytes. A byte being 8 bits or 8 1's and 0's of actual information. As drives increase in size, this inaccurate form of measurement becomes more and more noticeable.
For example:
1GB is supposed to consist of 1,073,741,824 Bytes
a 1GB HDD consists of only 1,000,000,000 Bytes
1TB should consist of 1,099,511,627,776 Bytes
1TB HDD only contain 1,000,000,000,000 Bytes
That is 10% of the advertised space.
To calculate the actual space:
True size (64,000,000,000 Bytes) / Advertised size (68,719,476,736 Bytes) = .931
.931 * 64GB = 59.6GB
Now subtract about 2GB for the OS.
As for your 16GB iPhone 5:
True size (16,000,000,000 Bytes) / Advertised size (17,179,869,184 Bytes) = .931
.931 * 16GB = 14.9GB
Now subtract about 2GB for the OS.
