Sell Your iPhone 18 Pro Max
A3473, A3716, A3717, A3718
We pay up to £813, paid the same day.
Ask us for an iPhone 18 Pro Max figure today and you will get the 17 Pro Max value, marked as a stand-in rather than dressed up as something it is not. Apple confirmed the handset on 9 September 2026 and it goes on sale on 18 September, but a trade-in price comes from what used handsets actually change hands for, and none have yet. We take the real one in trade from release day.

Once we send your offer it will not drop, so you have time to decide.
We repair, so faulty still pays
Cracked screen or worn battery is a job on our bench, not a write-off.
Not the iPhone 18 Pro Max storage or condition you were looking for?
We buy a lot more than we list here. Older iPhones, Samsung and Pixel handsets, iPads, Apple Watches, MacBooks and games consoles all get a real offer, and a cracked or faulty device is still worth something to us because we repair them in house. Tell us what you have and we will come back with a firm price.
No obligation, and nothing to pay. We will not give you a number we cannot honour, so if we need to see it first we will say so.
Three steps
How selling your iPhone 18 Pro Max works
No haggling, no waiting on a callback, and no offer that quietly drops when you arrive.
Get your price
Pick your iPhone 18 Pro Max storage and condition above and the price we pay appears straight away, no waiting for a callback.
Get it to us, three ways
Walk into the shop, book a free collection from your door within 5 miles, or post it free from anywhere in mainland UK.
Paid the same day
Accept the offer and you are paid there and then, by bank transfer, or store credit towards an upgrade or downgrade.
Your price
What your iPhone 18 Pro Max is worth depends on
Storage
Bigger storage means a better price. Tell the finder above which iPhone 18 Pro Max you have and it prices that exact variant.
The top storage tiers on Pro Max handsets are usually the ones that hold value best, and that pattern has repeated across several generations. The 18 Pro Max adds a 2TB option above the familiar 256GB, 512GB and 1TB, so if you tend to buy the biggest capacity, that is worth knowing before you decide when to sell.
Screen condition
A cracked screen does not drop you to a faulty price. You keep the condition the phone is otherwise in and we simply take off what the glass costs us to replace, because we replace them ourselves.
Body and connector
Dents, scuffs and cracks to the casing are graded as part of the overall condition. A cracked back or a bent frame lowers the offer but rarely rules a device out.
This page is deliberately anchored to the outgoing iPhone 17 Pro Max rather than to the 18 Pro Max headline specification. A launch tells you what a phone is; it tells you nothing about what a used one is worth six months in, and we would rather anchor to a real handset with a real resale history.
If your current Pro Max is still under you, there is no penalty for checking a quote today and deciding later. The figure holds for the window we quote, so timing your sale around the 18 Pro Max is entirely your call.
Battery health
Our cut off is 90 per cent, so at or above that there is no deduction at all. Below it we take off what a genuine replacement costs us rather than calling the iPhone 18 Pro Max faulty. Apple's own 80 per cent mark is a repair threshold, not a resale one.
Apple has not published a battery capacity for the 18 Pro Max. Every Pro Max release so far has crept upward thanks to the bigger chassis, and we expect this one continues that, but until there is a published figure it stays an expectation rather than something we state as fact.
Whether it powers on
A device that boots and passes our checks is worth more than one that does not, but a dead handset is still worth telling us about rather than binning.
A Pro Max that has sat unused for a long stretch often will not wake up at all when someone finally digs it out. That does not put us off buying it, but it does change how you get a figure: our online quote needs the phone to switch on so its condition can be graded, so for a completely dead handset send photos over and we will give you a rough estimate, then confirm it properly once we have had a look at it.
iCloud or Google account lock
We can only buy your iPhone 18 Pro Max once it is signed out of iCloud, with Find My switched off.
Pro Max handsets often sit as a spare for months before anyone gets round to selling them, and by then it is easy to forget which Apple Account the thing is on, or whether Find My is still switched on. Worth checking before you send it, because we cannot test or resell a device that is still signed in, and sorting it out remotely once it is here is the slowest way to do it.
Original parts matter to the price: an aftermarket screen, battery or camera fitted by someone else changes what we can pay. If you are not sure what is in your iPhone 18 Pro Max, our guide on how to check a refurbished phone walks through what to look for.
Five minutes
Before you sell: five minutes that protect you
Do these before you hand the device over and the sale goes through without a hitch.
-
1.Back up what you want to keep
Photos, contacts and anything else you would not want to lose. If an upgrade is replacing it, here is our guide to moving everything to your new phone.
-
2.Sign out of iCloud or your Google account
Turn off Find My before you hand over the iPhone 18 Pro Max. A device still signed in cannot be bought from you.
-
3.Take out the SIM and any memory card
These are yours to keep and are not part of the sale.
-
4.Note down the IMEI
Dial *#06# or check Settings to find it, in case you want a record for your own files.

No surprises
Ownership, ID and your data
Three things worth knowing before you sell anything to anyone, not just to us.
The device has to be yours to sell
We cannot buy a device that is still under contract or on finance, because until it is paid off you are not yet its legal owner. We also cannot buy a device that is part of an ongoing insurance claim, or that has been reported lost or stolen.
"This device is not under contract or finance, is not part of an insurance claim, and has not been reported lost or stolen - I own it outright."
We record name, address and ID on every purchase
We record the name and address of everyone we buy from, and check them against photo ID and proof of address. HMRC requires it: buying from a private seller, we have to raise the purchase invoice ourselves and it must carry your details. Bring the documents into the shop and show us, or send a photo if the device is reaching us another way.
It protects you as much as us: the purchase can always be traced back to a genuine sale rather than an anonymous one. A photocard driving licence showing your current address covers both documents on its own.
GOV.UK: VAT margin schemes, section 6.2Your data is wiped at our shop
Once your device is checked in, it is fully wiped and factory reset at our shop before it goes anywhere else. Nothing of yours is left behind on it.
Locked in
Your price is held for 14 days
Once we send you an offer for your iPhone 18 Pro Max, it is held for 14 days. That gives you time to compare us against the online recyclers before deciding, without the price moving under you.

Selling your iPhone 18 Pro Max
When does the iPhone 18 Pro Max come out?
It was announced on 9 September 2026 and reaches customers on 18 September, the same day as the iPhone 18 Pro.
How much will an iPhone 18 Pro Max trade in for?
Your quote is currently anchored to the iPhone 17 Pro Max value. A trade-in figure reflects what a used handset sells for, and no 18 Pro Max has been used yet, so the number updates once we have assessed real ones.
Do the higher-capacity Pro Max versions sell for more?
Yes, the larger capacities have generally been worth more to us than the entry one, and we expect that split to carry over. The 18 Pro Max runs 256GB, 512GB, 1TB and 2TB, with the 2TB new this generation.
Do you buy the 2TB iPhone 18 Pro Max?
We do. There was no 2TB Pro Max last year, so there is no equivalent handset for us to anchor a price against, which is why no separate figure appears for it on this page yet. Message us and we will quote that capacity directly.
Is a repair the better move for the Pro Max I have now?
It can be, and you get a real choice here, because mendmyi runs a repair workshop alongside the buying side. A Pro Max you will keep another year, or pass down to someone in the family, is usually worth putting right. One you are only hanging on to until the 18 Pro Max arrives is usually better sold while interest in it is still strong.
How long does a confirmed offer stay open?
For 14 days, and the clock does not start when you first see a number on screen. It starts once we have had the handset in front of us and confirmed the offer, which is the point the figure becomes ours to stand behind.
