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 128 GB pays £25 less and the 256 GB pays £5 less. At the same capacity, the iPhone 14 Pro Max pays £50 more and the iPhone 15 Plus pays £13 more.
Smash the glass on a 512 GB and keep the picture, and it still pays £195; lose the picture or fit a replacement screen and it is £115. The glass is worth £20 at this size.
The same 512 GB in the models either side: iPhone 14 Pro Max 512 GB, iPhone 15 Plus 512 GB.
If Settings, General, About shows a Capacity other than 512 GB, use one of these instead: 128 GB, 256 GB.
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.
Top of the ladder
£5 separates this page from the 256 GB at Working grade, and there is nothing above it on this model. The premium is real but finite. Apple has typically asked around two hundred pounds for this step when its phones were new; the used market keeps part of that because big configurations are scarce, and hands the rest back because scarcity only pays when a buyer genuinely needs the room.
A rarer phone can wait a little longer for its buyer, which we plan for rather than punish. The figure above is the offer, not an opening position, and it holds for the same ten days as every other size on the site.
The rare one
The dearest configuration of any phone sells in the smallest numbers, and on the iPhone 15 that is the 512 GB. Scarcity mostly works for you here: when one does reach the used market it faces little competition, which is why the biggest number on this model lives on this page. The trade off sits at our end, in patience, and the price already accounts for it. Scarce cuts the other way if you plan to replace it like for like, mind: the used market will not be brimming with half terabyte options either. Above it there is nothing. No iPhone 15 was made bigger than 512 GB, so a listing offering one is describing a different phone.
The iPhone 15 in one paragraph
The first iPhone with USB-C, and the first non Pro model with the Dynamic Island. Both make it noticeably easier to sell on than the 14 next to it.
Worth knowing before you send it
The USB-C port is the newest part of this phone and the one that gets used most. A port that has stopped charging reliably is a repair, not a write off, and we price it as one.
iPhone 15 prices by size

| 512 GB this page | £215 | £195 | £115 |
£215 is locked for 10 days. Postage and the postage pack are free, and a phone that does not match its grade gets a revised offer you can turn down.

The 512 GB question
What is an iPhone 15 512 GB worth right now?
The size half of it is settled by the page you are on: the 512 GB is the top rung of this model's ladder, and nothing on this phone pays more. 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 15 page.
