Details that surfaced today from Chinese regulatory filings and posts by longtime leaker Ice Universe point to a meaningful jump in battery capacity for the upcoming iPhone 18 Pro Max. The device could ship with a 5,567mAh cell in its U.S. version. That figure sits nearly 500mAh above the capacity of the iPhone 17 Pro Max and marks one of the largest single-year gains Apple has targeted in recent memory.



A different filing reference mentions a slightly lower battery capacity, roughly 5,391mAh, on a non-US variant, while several reports round the headline figure to around 5,500mAh. In any case, the increase marks the biggest capacity Apple has ever placed into an iPhone. Ice Universe ignited a social media debate: if the device requires a 240-gram body and a thickness of nearly 9mm to accommodate the larger battery, will buyers be satisfied? The post drew a lot of attention because the dimensions contradict the recent trend of lighter, smaller Pro Max models.
