In recent times, the top-tier iPhone 15 Pro Max from Apple's iPhone 15 series is expected to be available only in November, which some interpret as a sign of strong demand. However, it is more likely due to production bottlenecks, particularly related to technologies like CIS, which have resulted in limited shipments of the iPhone 15 Pro Max. Overall, the estimated shipment volume for the iPhone 15 series may still reach up to 80 million units.
