Sell your iPhone 15
256 GB.
The 256 GB is the second of three sizes the iPhone 15 came in: worth more than the 128 GB and less than the 512 GB. All three prices below are for the 256 GB and confirmed before you post anything.
iPhone 15, September 2023, 6.1 inch Super Retina XDR OLED. This page is the 256 GB one.

Storage
Battery health 80% or more?
Settings, Battery, Battery Health. Ten seconds. Under 80 counts as Picture fine. Not sure is fine, we test it here.

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 256 GB worth checking?
Working, the 128 GB pays £20 less and the 512 GB pays £5 more. At the same capacity, the iPhone 14 Pro Max pays £50 more and the iPhone 15 Plus pays £18 more.
At 256 GB, Picture fine pays £190 and Picture faulty pays £115: smashed glass over a good screen takes £20 off, not the phone's whole value.
The same 256 GB in the models either side: iPhone 14 Pro Max 256 GB, iPhone 15 Plus 256 GB.
If Settings, General, About shows a Capacity other than 256 GB, use one of these instead: 128 GB, 512 GB.
256 GB, translated into things you own
After the operating system takes its cut you are looking at roughly 230 GB of usable room. Filling that takes commitment: about 22 hours of 4K footage at Apple's estimated 170 MB a minute, or a photo library well past seventy thousand pictures. Apps stop being part of the sum altogether, since even a heavy handful of games disappears into headroom like this. Plenty of 256 GB phones go their whole first life without coming near the ceiling.
Where the size does bite is on sending day. If yours actually is loaded, budget hours rather than minutes for the backup: a couple of hundred gigabytes over home Wi-Fi is a slow crawl, so set it going when the postage pack arrives rather than when you want to head to the post office.
£20 up from the 128 GB, £5 short of the 512 GB
Those two gaps, both at Working grade, are the honest shape of the used market: capacity earns its premium because it cannot be added later, but the model and the condition do the heavy lifting on price. Whatever Apple charged for those steps at the till, the second hand market keeps only the slice a real buyer will actually pay for.
If you are weighing what to tell us about damage, do not let the size distract you. A cracked screen moves this price a great deal further than either storage step does, and it moves it the same way on every size.
Bought on purpose
Nobody drifted into a 256 GB iPhone 15. It cost meaningfully more at the till, and the people who paid that mostly knew why. Used, the same logic holds: fewer of them about than the entry size, and a steady supply of buyers who specifically want the room, which keeps its premium honest rather than hopeful. Do glance at the About screen before settling on this page, because a memory of which size you bought years ago is less reliable than the Capacity line is.
Is this the iPhone 15 you have?
6.1 inches, USB-C, a Dynamic Island and two rear cameras in a square bump. The 14 before it has the same two lenses but a notch and a Lightning port. The 16 after it moved those two lenses into a tall pill shaped bump.
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.
iPhone 15 prices by size
| Size | Working | Faulty / Damaged - Screen Fine | Faulty / Damaged - Screen Bad |
|---|---|---|---|
| 128 GB | £190 | £170 | £98 |
| 256 GB this page | £210 | £190 | £115 |
| 512 GB | £215 | £195 | £115 |
£210 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 256 GB question
What is an iPhone 15 256 GB worth right now?
The size half of it is settled by the page you are on: the 256 GB sits between the 128 GB and the 512 GB, so it pays more than the one and less than the other. Condition does the rest, and we judge the glass and the picture apart from each other: cracked glass, or battery health below 80 per cent, is our middle grade, and a fault in the picture itself is the bottom one. The three figures at the top of this page are all for the 256 GB, and whichever one you order at holds for 10 days.
Cracked screens, battery health, Find My and how fast you are paid are answered on the iPhone 15 page.
