A new report<\/a> from Macworld based on social media leaks claims to know iPhone 18 Pro Max\u2019s exact battery capacity, and it seems impressive.<\/p>\n Here is the alleged iPhone 18 Pro Max battery capacity<\/p>\n Rumors have long indicated<\/a> that iPhone 18 Pro and iPhone 18 Pro Max will have larger batteries than their predecessors. Though recent reporting suggests it might not be by very much.<\/p>\n But today, Macworld shared<\/a> the following alleged iPhone 18 Pro Max battery capacities:<\/p>\n iPhone 18 Pro Max with eSIM: 5,425 mAh<\/p>\n iPhone 18 Pro Max with physical SIM: 5,235 mAh<\/p>\n These are fairly significant increases from iPhone 17 Pro Max\u2019s battery, which is 5,088 mAh and 4,823 mAh for eSIM and physical SIM models, respectively.<\/p>\n iPhone 17 Pro Max already has impressive battery life. And iPhone 18 Pro Max is expected to best it not only with a physically larger battery, but also efficiency gains provided by the A20 Pro chip<\/a>.<\/p>\n This report, however, has questionable sourcing.<\/p>\n It points to a variety of social media posts that are hard to trace to their original source.<\/p>\n The best argument for these battery numbers being accurate is that their timing coincides with the very real data breach<\/a> that Apple supplier Tata Electronics recently experienced. Leaks related to that breach show all signs of being legitimate.<\/p>\n We don\u2019t know if these battery numbers originated with the Tata breach, but their timing and questionable origins make that a possibility worth considering. And if they prove true, iPhone 18 Pro Max should last impressively long between charges.<\/p>\n Is a larger battery on your feature wish list? Or do you think iPhone 17 Pro Max is good enough?
