Why does the 128gb iPhone 6+ only have 109gb?

That is the probably space available to you at this moment. The rest is taken by iOS (the operating system), the basic free apps and maps/sounds/games that come with it and of course any pictures video you may have done.

  • Why is my 128GB iPhone 6S so low on storage? My two most space-consuming apps or my music and photos, which combined take up exactly 11GB. All my other apps combined use up about 10GB total… So why does my phone say I only have 8GB of space available? About a month ago I checked and it said I had 80GB of available space. Also, its software is completely up-to-date if that may have anything to do with it.

  • Why does my 16GB iphone only have 13.25GB capacity? I think it's kind of strange that my 16GB iPhone only has a memory capacity of 13.25GB. Does anybody know why this is? I assume it's because that's how much memory is left after the operating system is installed, but I think it's rather bizarre to advertise it as 16GB when that's not what you'll actually be able to use.
