Apple may not launch the iPhone 18 Pro and 18 Pro Max until September, but regulatory filings offer more details about its next-generation smartphones. Documents submitted to the Chinese certification authority include details on the battery capacity of the upcoming iPhones. While the models are not specifically named, the timescales and details align with supply chain details and the wider community expectations.
What Are The iPhone 18 Pro Battery Specifications?
Apple’s iPhone 18 Pro battery architecture offers more capacity in US and Chinese models, a strategic increase necessitated by the heightened power draw of local on-device AI processing via the A20 chipset.
Two capacities are listed for the iPhone 18 Pro, one for a Chinese model and one for a US-bound model. The former is rated for 4.065 mAh, and the latter 4,288 mAh. That is a rise of 77 mAh and 36 mAh from the iPhone 17 Pro’s listed specifications. The iPhone 18 Pro has a slightly higher increase. The iPhone 18 Pro Max will be lifted up by 568 mAh to 5,391 mAh in China, and by 479 mAh to 5,567 mAh in the US.
