Weeks before its anticipated September launch, details regarding the iPhone 18 Pro Max battery capacity have reportedly leaked, suggesting a substantial upgrade. An alleged photo of a battery pack, purportedly for the Chinese market, indicates a capacity of 5,391mAh.
Significant Battery Capacity Increase
This 5,391mAh figure marks an 11.8% increase compared to the iPhone 17 Pro Max, which features a 4,823mAh battery. The information, initially shared on Weibo in China and then reposted on South Korean platform Naver, gains further credibility as the same 5,391mAh capacity reportedly appeared in a regulatory database last month.
Other iPhone 18 Models and Regional Differences
While the focus is on the Pro Max, the standard iPhone 18 Pro model is also expected to receive a battery upgrade, with a rumored capacity of 4,056mAh. This is an increase from the iPhone 17 Pro's 4,288mAh battery, correcting an earlier typo in the source material where it stated 4,056mAh was higher than 4,288mAh.
Interestingly, the US version of the iPhone 18 Pro Max could potentially feature an even larger battery. This is attributed to the absence of a physical SIM card tray, which frees up internal space. Apple has already removed physical SIM trays from iPhone 17 Pro models in several regions, including Canada, Japan, Mexico, Saudi Arabia, and the UAE, suggesting a trend towards regional battery capacity variations.
It is important to note that Apple has not officially confirmed any of these specifications. Consumers will need to await the official launch event for definitive details on the iPhone 18 Pro Max battery and other upgrades.
