New information about the iPhone 18 Pro Max was revealed this Tuesday, August 11, 2026, with the release of real images of the device’s battery. The model, which is already being assembled in China, promises to bring record energy capacity to Apple’s smartphone line.
According to the leak, the iPhone 18 Pro Max variant that will use a carrier chip in China will feature a 5,391 mAh battery. However, for the exclusive model with eSIM connection, the capacity reaches an impressive 5,567 mAh. This number had already been indicated in previous rumors and represents a significant leap in the device’s autonomy. For context, the current iPhone 15 Pro Max has a 4,422 mAh battery, which means that the new model with eSIM will have an increase of approximately 25% in capacity. In practice, this can translate into more hours of intense use and less worry about recharging throughout the day for users.

iPhone 18 Pro battery records smaller improvement
While the Pro Max version surprises with its autonomy, the iPhone 18 Pro may not present such a significant advance. The same source that released information about the most expensive model points out that the iPhone 18 Pro, with a physical chip, will have a 4,056 mAh battery. The variant with eSIM will hit the market with 4,288 mAh.
This increase represents only a 1% to 2% growth compared to previous models, a notably smaller difference than that of the iPhone 18 Pro Max, which can have between 9% and 12% more capacity. Perhaps the smaller model preserves size for the consumer experience.
Production faces challenges and may delay delivery
Apple, as usual, does not comment on leaks. However, the technology giant is working hard to launch the iPhone 18 Pro series in September 2026, despite a market scenario considered challenging. Sources close to production indicate that shipping of new iPhones may be delayed, mainly due to the global shortage of memory chips.
In addition to production challenges, there are expectations that an Apple foldable model could be presented in September, although sales should only begin at the end of the year. These market and component conditions can influence not only deadlines but also final values.
Expected prices and specifications of the new devices
It is widely expected that the prices of new devices will rise considerably, reflecting production costs and technological appreciation. As the launch approaches, more details should emerge about the values.
