Is it still supported?
Apple publishes no end date, and this site does not guess one. The support card on the iPhone 18 Pro Max page says what is known and where it came from.endoflife.date — iPhone, retrieved 2026-09-10
What the iPhone Duo changes
This line has nothing newer on this site; the newest Apple phone within a year of it is the iPhone Duo at £1,999, released 23 October 2026. Judged row by row against our published thresholds; the full table is at iPhone Duo vs iPhone 18 Pro Max.
On the makers’ published figures, the iPhone Duo wins on display size (7.6 in against 6.9 in); the iPhone 18 Pro Max wins on claimed video playback (43 h against 31 h). The difference in weight is below the threshold you would notice. Both state the same refresh rate, peak brightness, typical brightness, HDR peak brightness, storage (base), RAM and wireless charging. The other 32 rows have no threshold or no direction to judge by, so nobody wins them.

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.
