The battery capacities within the upcoming Apple iPhone 18 Pro and Pro Max have become a subject of considerable interest after a high-profile information theft from a Tata-controlled iPhone factory in India revealed a sizable bump in battery capacities for the Pro duo.
Well, just a few days later, we've now become privy to the official battery capacities that Apple's iPhone 18 Pro and Pro Max will sport, courtesy of a regulatory filing.
As we noted at the beginning of July, a Weibo-sourced screenshot of the iPhone 18 Pro duo-related documents - which were presumably stolen from a Tata-controlled factory in India - detailed that the eSIM variant of the Apple iPhone Pro Max was to sport a 5,425mAh battery, while its physical SIM card-bearing counterpart was presumably all set to go with a more modest 5,235mAh one.
Then, just a few days later, the tipster Ice Universe disclosed that the eSIM variant of the iPhone 18 Pro Max will, in fact, come equipped with an even larger 5,567mAh battery , which when combined with a dedicated vapor chamber and the A20 Pro chip's improved CPU scheduling, should allow the apex Pro variant to surpass its Android counterparts bearing ~7,000mAh silicon-carbon batteries.
Now, the tipster Digital Chat Station has disclosed China's C3 database filings that show:
- The iPhone 18 Pro in the US will sport a 4,288mAh battery.
- The iPhone 18 Pro in China will feature a 4,056mAh battery.
- The iPhone 18 Pro Max in the US will sport a 5,567mAh battery.
- The iPhone 18 Pro Max in China will feature a 5,391mAh battery.
Of course, the difference between the battery capacities in the two regions is likely due to the eSIM-only status of the iPhones sold in the US since the iPhone 14 lineup, where the removal of a physical SIM card tray provides more room for a bigger battery.
Also, do note that the iPhone 17 Pro Max's eSIM variant sports a battery capacity of 5,088mAh, which means that the next-gen Pro Max is coming with a nearly 10 percent bigger battery in the US.
