What yours is worth
Our reading of the figures
Apple publishes no end date for the iPhone 17 Pro Max’s security updates, so support is not a reason to move until it is.
The iPhone 18 Pro Max clears our noticeable threshold on one row: claimed video playback. 3 more gaps are borderline, which most people would not notice. Nothing goes backwards.
At £1,299 new, less the £594 CeX was paying for a grade A iPhone 17 Pro Max on 2025-11-25, the move costs about £705.
