iPhone 18 Pro Max rumor roundup: bigger battery, brighter display, and higher prices

Early rumors for the iPhone 18 Pro Max describe a bigger 5,567 mAh battery on eSIM models, a Samsung M16 OLED display for brighter, more efficient visuals, and an energy-efficient A20 Pro chip, all boosting endurance; despite display-cost savings, production costs are expected to rise up to 38%, potentially lifting prices by $100–$300. The design gets minor refinements with a thicker chassis and a new dark cherry color, plus increased trade‑in incentives. Launch is slated for September 9 with pre-orders likely on September 12, and camera/AI enhancements including Siri improvements aim to justify the upgrade.
