Do new iPhones have all 8GB or is some already used up?

Updating my iPhone always takes up a lot of space… When you get a new iPhone do you have all 8 gigs (or whatever it is), or is some space already used? (like for the apps you can't get rid of or whatever? My iPhone is 8GB but I only have 6.5 possible to use in usage… (I've already used 6.5/6.5 lol)

Yes, the system uses about 2 GB. Get an iphone of 32 GB. That'll give you plenty of space

All phones would not come with the advertised space available to the user. Just the nature of the product.
