A separate first-week estimate
A separate market estimate put combined first-week sales of iPhone 18 Pro and iPhone 18 Pro Max in China near 1.3 million units, about 15% above the combined first-week total for iPhone 17 Pro and iPhone 17 Pro Max. The same estimate put the Pro Max at 55.5% of the newer pair’s combined first-week sales. This comparison uses a full first week for each pair, unlike the 12% figure’s three-day-to-full-week comparison.
