How much usable space is on a 16 & 32 GB iPhone 5s out of the box before anything is installed on it? Just cruious, thanks! :)
 
why would they not make it with that much more capacity for software? I don't get the 16GB but only 13-14GB is available because of iOS.

The storage chips come in sizes that are multiples of 2. Given that the size of the iOS varies from one release to the next, and for each device type (iPod/iPad/iPhone) it would be impossible to ensure a precise amount of available storage on every device.
 
32GB is not actually 32GB that we have been trained to know. It is based off of 1GB being 1000MB instead of 1GB being 1024MB.

32GB would normally be 32,768MB, but in this case it is actually 31,250MB. So right off the back you lose about 1.5GB of storage based off the calculations of what is actually a GB. Then you will lose about 1-2GB on the iOS install.

My 32GB iPhone 5S has 27.9GB capacity.

Let's say I have a bag of rocks. I want to know how much it weighs, so I put it on a scale. Oh look, it's 10lbs! But one of my crazy friends uses the metric (?) system. According to him, it's 5 kilos. Now did I actually lose 5lbs there or is it just in the way we're measuring it? Since it's clearly labeled on the box I'd say it's more lack of customer knowledge and understanding causing the problem rather than the way the storage capacity is actually being measured, that or apparently no one has used any type of storage drive in the past 15 years.

Well, if you go onto Apple's iPhone website, or even iPad for that matter. (http://store.apple.com/us/buy-iphone/iphone5c) Scroll to the bottom and it says 1GB is 1 billion bytes. Technically 1GB is 1,073,741,824 bytes. 73.7 million bytes per GB makes up a lot of lost space.
 
Actually you can't see the box in stores until you buy the phone. And they never give you the box to open, they open it for you, so at that point, you are pressured to buy the phone.

Except that it is the way how storage capacity is being measured

It should technically be MiB (mebibyte) or GiB (gibibyte). Bi meaning binary. For whatever reason, they use MB instead of MiB, likewise GB instead of GB on all OS systems

Advertised storage is in base 10 while calculated storage by the computer is base 2

As said above, the advertised storage is less than actual storage

10^6 = 1,000,000 bytes or 1 MB
10^9 = 1,000,000,000 bytes or 1GB
2^30= 1,073,741,824 bytes or 1024 MiB (look below for conversion rates) or 1 GiB

2^10 = 1024 bytes = 1 KiB
2^20 = 1,048,576 bytes = 1 MiB

They advertise in terms of base 10 instead of base 2 most likely because it gives the impression of "more space" and also to simplify things.

Easier to advertise 1000GB instead of 931.32GB

why would they not make it with that much more capacity for software? I don't get the 16GB but only 13-14GB is available because of iOS.
