IPhone 18 Pro Max leak indicates biggest battery in Apple history
New leaks revealed real images of the iPhone 18 Pro Max battery, indicating that the model is already in the assembly phase in China and with the launch getting closer.
The information shows that the variant of the device with an operator chip, destined for the Chinese market, will have a capacity of 5,391 mAh.

For the model with exclusive connection via eSIM, the battery capacity promises to be even greater, reaching 5,567 mAh, a figure that had already been anticipated in previous leaks.
These revelations reinforce the visual nature of the leaks that emerge before Apple’s official announcements.
Discreet battery growth on iPhone 18 Pro
In contrast to the significant advancement of the Pro Max model, the iPhone 18 Pro may not present such a significant increase in its battery capacity, which may frustrate some users.
The same source as the images indicates that the version with a physical chip slot of the iPhone 18 Pro will have 4,056 mAh. The model that only operates with eSIM will have 4,288 mAh.

Possible delays in the delivery of iPhones 18 due to lack of memory chips
Apple traditionally does not comment on leaks, but the company continues working to launch the iPhone 18 Pro line in September, even in the face of a challenging market scenario.
However, recent information indicates that shipping of new devices may be delayed. Furthermore, although a possible folding model could be presented in the same month, its sales are only expected by the end of the year.
