Overview
- Multiple regulatory listings and repeated Weibo leaks report the iPhone 18 Pro Max could carry roughly 5,391–5,567mAh of battery capacity, a near 500mAh jump over the current model, but these figures remain unconfirmed.
- A prominent leaker has claimed the Pro Max will measure about 9mm thick and weigh around 240 grams, though other tips disagree on whether that extra depth applies to the whole chassis or only an enlarged rear camera plateau.
- Reports tie the larger cell to internal design changes such as a stainless‑steel vapor chamber for cooling, retention of an aluminum alloy frame, and a bigger camera assembly with a possible variable‑aperture lens, all of which would add bulk.
- Counterpoint Research estimates the bill of materials for high‑end Pro Max configurations could rise by nearly $300 because of surging NAND and DRAM prices plus a move to a 2nm A20 Pro chip, which raises the likelihood of retail price increases and constrained early supply.
- Apple has not confirmed any specs and still plans a customary September unveiling, so buyers should expect a trade‑off between noticeably longer runtime and a slightly thicker, heavier, and likely more expensive Pro Max.
