Apple has officially revealed the battery capacities of the iPhone 18 Pro and iPhone 18 Pro Max, providing details that the company typically does not include in its standard technical specifications.
The battery information has been disclosed through the European Union’s mandatory Energy Labels, which require manufacturers to provide specific information about smartphones and other electronic devices sold in the region.
According to the labels, the EU version of the iPhone 18 Pro features a 4,056mAh battery, while the larger iPhone 18 Pro Max comes with a 5,391mAh battery.
The difference between the two models is substantial, with the iPhone 18 Pro Max offering considerably more battery capacity than the standard Pro model. The larger battery is consistent with the Pro Max’s bigger overall design and display, giving Apple additional capacity to support demanding hardware and extended usage.
Apple traditionally focuses on battery life estimates rather than publishing exact battery capacities in its iPhone specification sheets. As a result, regulatory documents and certification databases often become the source of precise battery figures for Apple devices.
The newly disclosed capacities provide consumers with a clearer picture of the hardware inside Apple’s latest Pro models. Battery capacity is only one factor that determines real-world battery life, however, as efficiency depends on the processor, display technology, software optimization, connectivity and other components.
The 5,391mAh capacity of the iPhone 18 Pro Max stands out particularly because it gives the flagship model a significant capacity advantage over the iPhone 18 Pro. Users who prioritize longer battery endurance may therefore find the Pro Max particularly appealing.
The EU Energy Labels also represent an important source of standardized information for consumers. Beyond battery capacity, the European labeling system is designed to provide information that can help buyers compare the energy efficiency, durability and other characteristics of electronic devices.
For Apple fans and technology enthusiasts, the official battery figures remove some of the uncertainty that typically surrounds iPhone hardware specifications. While Apple may emphasize overall battery performance rather than raw capacity, the regulatory disclosures offer a precise measurement of the batteries powering the two Pro models.
With the iPhone 18 Pro listed at 4,056mAh and the iPhone 18 Pro Max at 5,391mAh, the latest disclosure gives users a direct comparison between Apple’s two premium smartphones.
