Sep 18, 2015 12:34 AM in response to Kilgore-Troutby dmtrchr,i add my apps and i get ca. 7.4gb. plus the 1.4 maximum of ios9 it's 8.8, as it's stated in my iphone6. plus another 2.8 free the total storage is 11.6. apart from that, in the "settings"-> "information" i read 11.8gb capacity. i cnt figure out where.s the rest 4.4...

Sep 18, 2015 12:40 AM in response to David Shanahanby dmtrchr,4.4 "missing" gb's in mine is too much, i think! regarding the fact that the ios9 is only ab 1.4. well, "info" says 11.8gb capacity. i add my apps and i get ca 7.4 from the used 8.8 and i guess that ios9 is included in that 8.8. plus another 2.8 free here is the 11.8. what ab the rest 4.4, which is tooooo much???

Sep 18, 2015 12:49 AM in response to dmtrchrby Ingo2711,If you have a 16GB iPhone, the usable space has always been around 12GB, the reason for that is the different calculation of the storage capacity:
How OS X and iOS report storage capacity - Apple Support
And other devices have the same capacity issue:
size of usable space in base model iPhones following larger iOS 8 updates

This solved my question Solvedby Axeman1020 on Sep 25, 2014 10:13 PM
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.

Sep 20, 2015 5:36 AM in response to Resurrect Steveby David Shanahan,Where on earth did you hear that this is how it works? This is not true, iOS does not "reserve" any space for future updates. It never has and certainly does not now with iOS 9. Once an upgrade is finished any temporary work space used by the update process is freed and made available for general use.
iOS 9 updates require much less free space than previous releases (about 1.3GB vs around 4.5GB in 8.0). If your device still does not have enough free space to download and install the upgrade it will offer to delete installed apps until enough space is freed up to perform the update and once the upgrade is finished it will automatically reinstall the deleted apps from the app store.

Dec 4, 2015 5:33 PM in response to Germanmaccariby GroovyMotion,Hi. I had the same problem and i just fixed deleting all the stuff i found in the system/downloads directory on the iphone. You can get to that folder by using some file manager for iphone. I used AnyTrans. Hope that helps. The iOS 9.1 then shows as 2,8 gb. I guess that's still better than having another 5 GB of Others on the list left out of all installation files and other things.

Mar 9, 2016 8:19 AM in response to Germanmaccariby dp111271,I have deleted several apps over the last few days. My iPhone shows 11.3 of data used with 371 mb available. Why is IOS taking up 4gb of data on my phone? I did not have storage problems until recently. I have about 100 pictures and less than 25 apps with 2gb of music. I never had this problem before on any other phone. My phone is running terrible and apps force close constantly. Please help!!

Mar 9, 2016 8:23 AM in response to dp111271by deggie,iOS doesn't take up 4GB, it has to do with how the space available is measured by the OS compared to drive manufacturer descriptions.
Do you have WhatsApp on your iPhone?

Aug 12, 2016 11:06 AM in response to Germanmaccariby kevinkendall,Regarding general hard drive and iPhone and what have you storage devices showing less than their manufacturer-stated capacity, the reason for the difference in the numbers is very, very simple. The reason has to do with marketing, and with simplicity in storage device manufacturers labeling their products. Here it is:
All computer devices are manufactured for, & operate using, the binary numbering system; i.e., the Base 2 numbering system; i.e., 1's and 0's. However, for simplicity's sake more than for any other reason I suppose, manufacturers *report and advertise* their storage devices' capacities in the "normal" everyday-use decimal numbering system; i.e., the Base 10 numbering system.
So when a memory storage manufacturer builds an iPhone's memory for 32GB, or a desktop or laptop hard drive for, say, 1TB, then the resulting Base 10/Base 2 storage capacity calculates out to, for the 32GB iPhone, as 32,000,000GB total stated Base 10 amount ÷ 1,048,576GB of similarly close Base 2 amount per Gigabyte = 30.517578125GB. For the 1TB hard drive, that'd be 1,000,000,000GB (Base 10) ÷ 1,048,576 (Base 2) = 953.67431640625GB real, actual storage space amount.
Partitioning and formatting reduces that "real, actual storage space amount" just a bit more.
So there it is..... Marketing, a difference in the Base 10 "human" numbering system and in the "computer" numbering system, and simplicity in labeling.

Aug 13, 2016 7:43 PM in response to Germanmaccariby alec.t238,The capacity is telling you how much space you have when the ios operating system is installed. The original capacity is 16 but the ios system takes up some space.
