answer:This would depend on which size memory you chose in the first place: 16, 64, or 128GB. Then the iOS and the pre-installed apps take up memory, so there will be about 8–10GB less than what is listed. From Apple’s Knowledge Base: ”The storage media in your Apple product, like all storage devices, uses some of its capacity for formatting, so actual capacity available for applications and files will be less. In addition, other factors, such as pre-installed systems or other software and media, will also use part of the available storage capacity.”
