A fresh set of photographs has added another layer to speculation around the iPhone 18 Pro Max, with an alleged battery cell carrying a 5,391mAh capacity marking that matches a figure leaked more than a month earlier.
The images, shared on Naver by Yeuz1122, show what is claimed to be an iPhone 18 Pro Max battery from multiple angles. The component appears to carry Apple branding, regulatory information and markings near the connector, while the capacity printed on the cell is said to read 5,391mAh.
What makes the photographs more interesting is not simply the size of the claimed battery. It is the fact that the number has appeared before.
A separate leak dated July 6 had also listed a 5,391mAh battery capacity for the US version of the iPhone 18 Pro Max. The new photographs surfaced on August 10, placing the same unusually precise figure back in circulation 35 days later.
That repetition gives the rumor more weight, although it still stops well short of confirmation.
The exact number is the key detail
Battery rumors often arrive as broad claims about improved endurance or larger cells. Here, the detail drawing attention is much more specific.
The alleged component is not simply being described as having a battery larger than its predecessor. It reportedly carries a precise 5,391mAh figure within its regulatory text.
That matters because an exact capacity appearing across separate leaks is harder to dismiss as a vague prediction. At the same time, matching numbers do not establish authenticity on their own.
The photographs show the front and rear of the alleged battery as well as its upper section. Apple branding and regulatory text are visible, including a smaller printed area close to the connector.
There is still no confirmation from Apple that the part belongs to the iPhone 18 Pro Max.
A stronger clue, but still a leak
The appearance of a photographed component changes the character of the rumor, but not its status.
Until now, the 5,391mAh figure existed as a claimed specification. The new images appear to give that number a physical reference point, with the same capacity reportedly printed on a battery said to be intended for the upcoming Pro Max model.
That is useful supporting evidence, but photographs alone cannot settle the question.
Images of unreleased hardware can be misidentified, altered or originate from prototype and test components that never reach retail devices. With the iPhone 18 Pro lineup reportedly approaching its introduction, more component leaks are also likely to surface before Apple confirms the final specifications.
The available information itself leaves room for caution, noting that even photographs and video cannot automatically be treated as genuine and that definitive confirmation will come only when the product is launched.
What the latest leak actually tells us
For now, there are three points that can be stated without stretching beyond the evidence.
Photographs have surfaced of a battery claimed to be for the iPhone 18 Pro Max. The cell is said to carry a 5,391mAh capacity marking. And that figure matches the capacity previously attributed to the US model in a July 6 leak.
What cannot yet be said is that 5,391mAh is the confirmed battery capacity of the final iPhone 18 Pro Max.
Apple has not announced the specification, and the authenticity of the photographed component remains unverified.
Still, the second appearance of exactly the same capacity figure makes this more notable than a standalone battery rumor. If the component proves genuine, the 5,391mAh marking could offer an early look at one of the more closely watched hardware changes in Apple’s next Pro Max model.
Until then, the number is best treated as a increasingly consistent leak, not an official specification.
