Sell your iPhone 17 Pro Max
1 TB.
The 1 TB is the third of four sizes the iPhone 17 Pro Max came in: worth more than the 512 GB and less than the 2 TB. All three prices below are for the 1 TB and confirmed before you post anything.
iPhone 17 Pro Max, September 2025, 6.9 inch Super Retina XDR OLED at 120 Hz. This page is the 1 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 1 TB worth checking?
Working, the 256 GB pays £79 less, the 512 GB pays £45 less and the 2 TB pays £25 more. At the same capacity, the iPhone 17 Pro pays £80 less and the iPhone 18 Pro pays £79 more.
Smash the glass on a 1 TB and keep the picture, and it still pays £560; lose the picture or fit a replacement screen and it is £423. The glass is worth £125 at this size.
The same 1 TB in the models either side: iPhone 17 Pro 1 TB, iPhone 18 Pro 1 TB.
If Settings, General, About shows a Capacity other than 1 TB, use one of these instead: 256 GB, 512 GB, 2 TB.
A terabyte, in human units
Call it 980 GB once iOS has taken its share. At the 170 MB a minute iOS quotes for 4K, that is roughly four days of continuous footage, and in photographs it is a number with no practical meaning, several hundred thousand of them. Which is the point of the size: a terabyte is not bought to be filled, it is bought so its owner never has to think about space again.
For the send, the advice is the same as for any big phone, only more so. Start the backup early, and use a cable rather than Wi-Fi if you can, because moving anywhere near a terabyte wirelessly is an overnight job at best. The erase at our end is the quick part. And before planning an overnight job at all, look at the iPhone Storage screen in Settings: it tells you how much of the terabyte ever got used, which on a size bought for peace of mind is often the smaller share.
One step from the very top
This is the only page on the site where 1 TB is not the end of a ladder: the 2 TB above it pays £25 more at Working grade, and the 512 GB below sits £45 back. Steps this high up a range are thin air by normal standards, and the gaps reflect how few phones ever occupy them.
Which rung is yours takes one look at the About screen to settle, and at these prices that look is worth taking twice: £70 separates the 512 GB from the 2 TB, with this page sitting between them.
Almost the top
On any other iPhone a terabyte is the ceiling. On the iPhone 17 Pro Max there is a 2 TB above it, which makes this the first phone where 1 TB reads as the sensible option rather than the extravagant one. It is still a genuinely scarce configuration, and scarce still pays.
The iPhone 17 Pro Max in one paragraph
The largest screen in the range until the 18 Pro Max matched it, and the first iPhone with 2 TB of storage.
Worth knowing before you send it
No known weak point yet on a phone this new. The thing actually worth doing before you send it is checking the capacity in Settings, because this model spans 256 GB to 2 TB and that spread moves the price further here than on anything else we buy.
iPhone 17 Pro Max prices by size

| 2 TB | £710 | £560 | £443 |
£685 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.
How to tell it from the model next to it is on the iPhone 17 Pro Max page.

The 1 TB question
What is an iPhone 17 Pro Max 1 TB worth right now?
The size half of it is settled by the page you are on: the 1 TB sits between the 512 GB and the 2 TB, so it pays more than the one and less than the other. Everything after that is condition. Glass and picture are graded separately here, so a cracked 1 TB whose picture is still perfect prices in the middle rather than at the bottom, and only a display faulty in itself goes lower. A battery under 80 per cent lands in that same middle grade. Whichever of the three figures above turns out to be yours is locked for 10 days once you order.
Cracked screens, battery health, Find My and how fast you are paid are answered on the iPhone 17 Pro Max page.
