2 TB.
The 2 TB is the largest iPhone 18 Pro Max Apple made, which makes this the highest price on the model. All three prices below are for the 2 TB and confirmed before you post anything.
iPhone 18 Pro Max, September 2026, 6.9 inch Super Retina XDR OLED at 120 Hz. This page is the 2 TB one.

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 2 TB worth checking?
Working, the 256 GB pays £150 less, the 512 GB pays £90 less and the 1 TB pays £40 less. At the same capacity, the iPhone 18 Pro pays £100 less.
With cracked glass and a good picture the same 2 TB is £894, and with a bad LCD or a replacement screen it is £624, so the cracked glass costs you £10 at this size rather than the whole value of the phone.
The same 2 TB in the models either side: iPhone 18 Pro 2 TB.
If Settings, General, About shows a Capacity other than 2 TB, use one of these instead: 256 GB, 512 GB, 1 TB.
What 2 TB even means in a phone
It means about eight days of continuous 4K video, going by the 170 MB a minute iOS estimates on its own settings screen, or a photo library with no realistic ceiling. Ordinary use cannot fill 2 TB. It exists for professional video, ProRes files and people who treat the phone as the archive itself rather than a window onto one.
If yours really is carrying serious footage, plan the transfer like the job it is: a cable, a computer with room to receive it, and a spare evening. Our side of the process is unchanged by the size. Yours is the slow half, so it is the half worth starting first.
£904 and nothing above it
There is no bigger iPhone to weigh this against, on our list or anybody's. The 1 TB below pays £40 less at Working grade, and the gap exists because a 2 TB phone is barely competing with other iPhones at all: the buyer who wants one has no substitute to haggle with, and neither do we when we come to sell it on.
Unique does not mean specially treated, though. The number comes off the same price list as everything else here, holds for the same ten days, and splits into the same three grades, so a cracked screen on a 2 TB phone is a known cost rather than a negotiation.
Worth a second look at the About screen
At this price the ten second check earns its keep twice over. Capacity is the one part of the quote you can verify to the letter before posting anything: open Settings, General, About, and the Capacity line either reads 2 TB or it does not. If it turns out to read 1 TB, the smaller page is yours, and the number there is still among the largest on the site.
One thing about the sizes
256 GB to 2 TB, the same spread as the 17 Pro Max before it. The capacity is in Settings, General, About, and it is worth a look before you send it.
Worth knowing before you send it
No known weak point on a phone this new. It went on sale on 18 September 2026. The 6.9 inch 120 Hz display is the dearest screen we buy, so even with the glass gone it keeps a proper price here.
Is this the iPhone 18 Pro Max you have?
6.9 inches with three cameras, the largest iPhone of 2026. The 17 Pro Max is the same size and shape, so if the box has gone, Settings, General, About is the quickest way to be sure which you have.
The iPhone 18 Pro Max in one paragraph
The biggest and newest iPhone we buy, with the variable aperture main camera that arrived with this generation. Finishes: Black, Silver, Glacier and Burgundy.

The 2 TB question
What is an iPhone 18 Pro Max 2 TB worth right now?
The size half of it is settled by the page you are on: the 2 TB is the top rung of this model's ladder, and nothing on this phone pays more. 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 2 TB, 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 18 Pro Max page.
