Overview
- The leak, which surfaced on Monday, includes multiple photos and a prior regulatory entry showing a 5,391 mAh battery for the China model of the iPhone 18 Pro Max and reports of a ~5,567 mAh eSIM‑only U.S. variant.
- Reports say the capacity gap is explained by regional SIM‑tray differences because removing a physical SIM frees internal room for a larger cell.
- Industry research from TrendForce says rising memory and chip costs have pushed the iPhone 18 Pro bill of materials sharply higher and may keep base storage at 256GB while making retail price increases of roughly $200–$300 likely.
- Newsrooms stress the materials remain unverified because images and database entries can be forged, and final confirmation of battery sizes and prices will come only from Apple at its September launch.
- If the reported numbers are accurate, buyers could see noticeably longer Pro Max battery life but also small increases in device thickness or weight and higher purchase prices for some storage tiers.
