Not sure which one is yours? Picture fine means the picture is perfect however the glass looks. Picture faulty means the display itself is faulty or has been replaced. Hidden faults, battery to Face ID, are accepted in both. Our three grades, explained properly.
Is the 512 GB worth checking?
Working, the 256 GB pays £34 less and the 1 TB pays £48 more. At the same capacity, the iPhone Air pays £176 less and the iPhone 17 Pro Max pays £83 more.
At 512 GB, Picture fine pays £501 and Picture faulty pays £352: smashed glass over a good screen takes £56 off, not the phone's whole value.
The same 512 GB in the models either side: iPhone Air 512 GB, iPhone 17 Pro Max 512 GB.
If Settings, General, About shows a Capacity other than 512 GB, use one of these instead: 256 GB, 1 TB.
Half a terabyte of phone
Even after iOS helps itself you keep roughly 490 GB, and the arithmetic turns absurd: two full days of continuous 4K at 170 MB a minute, or around 160,000 photos, or getting on for five thousand downloaded albums. Nobody fills this by accident.
Which tells you who owns one. A 512 GB phone belongs to somebody who films, records, archives or simply never deletes, and if that is you, the backup before the wipe is the one part of selling worth planning. Copying half a terabyte of originals off a phone can take the better part of a day over Wi-Fi, so a cable to a computer is the kinder route. Before you assume the worst, check the iPhone Storage screen in Settings: it shows exactly how much of the half terabyte you actually used, and the answer is often less frightening than the capacity suggests.
What the terabyte would have paid
At Working grade this page sits £34 above the 256 GB and £48 short of the 1 TB. The upper gap is the interesting one. Apple charged roughly two hundred pounds for it new, and the used step is a fraction of that, because a buyer who genuinely needs a terabyte is rare and everyone else prices room they will never use at close to nothing.
None of which you can change now, but it is the reason we quote each size exactly instead of folding them into one hopeful figure: on this model the sizes really are different money.
The filmer's size
On the iPhone 17 Pro the 512 GB sits above the sizes most people bought and below the terabyte almost nobody did. It is a deliberate choice, made by people who shoot a lot of video or simply never delete, and it behaves that way second hand too: fewer of them in circulation, met by a steady trickle of buyers who specifically want the room. Rare but wanted is a comfortable place for a price to sit. Do confirm the Capacity line before you settle on this page, because from the outside a 512 GB phone is identical to its smaller siblings and only one of them earns this number.
Is this the iPhone 17 Pro you have?
6.3 inches, three rear cameras, and an aluminium body after two years of titanium Pros. The plain 17 is the same screen size with two lenses. The 17 Pro Max is this phone at 6.9 inches.
The iPhone 17 Pro in one paragraph
The Pro moved back to an aluminium body with this generation, having been titanium for two years.

The 512 GB question
What is an iPhone 17 Pro 512 GB worth right now?
The size half of it is settled by the page you are on: the 512 GB sits between the 256 GB and the 1 TB, so it pays more than the one and less than the other. What is left is condition, and the three prices at the top of this page have already worked it out for the 512 GB: sound and working at the top, cracked glass with a good picture underneath in the middle, and a display with a fault of its own at the bottom. A battery under 80 per cent belongs in that middle one as well. Ordering holds your figure for 10 days.
Cracked screens, battery health, Find My and how fast you are paid are answered on the iPhone 17 Pro page.
