Apple's iPhone 18 Pro Max is on course to carry the biggest battery ever fitted to an iPhone, and US buyers will get more capacity than customers in China. Filings in China's 3C regulatory database list a 5,567mAh cell for the American model, first shared by Weibo leaker Digital Chat Station on Monday.
The timing matters because September upgrade decisions start now, and the numbers change the calculation. The Pro Max gains nearly 10% over last year's model while the smaller iPhone 18 Pro barely moves at all. Battery life is the upgrade ordinary buyers actually notice, and the split between the two Pro models could decide which one is worth the money.
