What the iPhone 18 Pro changes
This line has nothing newer on this site; the newest Apple phone within a year of it is the iPhone 18 Pro at £1,199, released 18 September 2026. Judged row by row against our published thresholds; the full table is at iPhone 18 Pro vs iPhone 17.
On the makers’ published figures, the iPhone 17 wins on weight (177 g against 211 g). 4 gaps are borderline, differences most people would not notice: HDR peak brightness (1,600 nits against 1,200 nits) for the iPhone 18 Pro, RAM (12 GB against 8 GB, both from GSMArena) for the iPhone 18 Pro, claimed video playback (34 h against 30 h) for the iPhone 18 Pro and fast charging (60 W against 40 W) for the iPhone 18 Pro. The difference in battery capacity is below the threshold you would notice. Both state the same display size, refresh rate, peak brightness, typical brightness, storage (base) and wireless charging. The other 37 rows have no threshold or no direction to judge by, so nobody wins them.
- HDR peak brightness: 1,200 nits → 1,600 nits borderline; marginal — most people won’t notice.
- RAM: 8 GB → 12 GB borderline; marginal — most people won’t notice.

What yours is worth
Our reading of the figures
Apple publishes no end date for the iPhone 17’s security updates, so support is not a reason to move until it is.
On the published figures, the iPhone 18 Pro does not win a single row by a gap you would notice; the differences are below our thresholds or have no direction to judge.
At £1,199 new, less the £405 CeX was paying for a grade A iPhone 17 on 2025-09-18, the move costs about £794.
Every sentence above is built from the figures on this page by a rule, not written for this phone: a support date, the rows that clear a published threshold, a price and a trade-in. There is no score and no recommendation. The methodology page has the thresholds and where they come from. Every phone’s version of this page is listed at All upgrade questions.
