Apple is expected to unveil the next-generation Apple iPhone 18 Pro and Apple iPhone 18 Pro Max in September 2026, and early leaks suggest the company could deliver major AI upgrades, a more powerful chipset, improved cameras and better battery life while keeping launch prices largely unchanged. According to multiple reports, Apple may absorb rising hardware and AI-related costs instead of passing them directly to buyers, although premium Apple Intelligence features could eventually come with subscription charges.Apple iPhone 18 Pro release date (Expected)Apple traditionally launches new iPhones during the first half of September, and the iPhone 18 Pro series is expected to follow the same pattern. Industry reports suggest the devices could debut during the first or second week of September 2026, with sales beginning shortly after the announcement.Apple iPhone 18 Pro price (Expected)Apple is reportedly aiming to maintain familiar pricing for its upcoming flagship lineup despite increasing manufacturing costs. According to reports, the Apple iPhone 18 Pro may cost about $1,099 or about Rs 1.05 lakh while the iPhone 18 Pro Max may be launched at $1,199 or about Rs 1.15 lakh. Do note that these prices are expected for the US market and hence it might be slightly high in India.For reference, the iPhone 17 Pro launched at Rs 1,34,900, while the iPhone 17 Pro Max debuted at Rs 1,49,900 in India. Reports suggest Apple may keep the iPhone 18 Pro lineup in a similar price bracket, though a minor increase cannot be completely ruled out.Apple iPhone 18 Pro design and displayThe iPhone 18 Pro series is expected to retain Apple's premium design language, including the triple-camera setup and flat-edge frame.Key display rumours include 6.3-inch display on the iPhone 18 Pro6.9-inch display on the iPhone 18 Pro MaxMore efficient LTPO+ display technologySmaller Dynamic IslandImproved screen-to-body ratioPopular tipster Ice Universe has claimed the Dynamic Island could become approximately 35 percent narrower than the current version, giving users more usable screen space.Apple iPhone 18 Pro processor and performancePowering the lineup could be Apple's next-generation A20 Pro processor.

The iPhone 18 Pro Max is rumoured to come with a 5,100 mAh to 5,200 mAh battery.The Pro Max could also become slightly thicker, allowing Apple to fit a larger battery.
