New reports suggest the iPhone 18 Pro Max will pack significantly larger batteries, potentially offering extended usage between charges. Leaked figures indicate the e SIM model could house a 5,425 mAh cell, with the physical SIM version at 5,235 mAh. These represent a notable upgrade over the iPhone 17 Pro Max's existing battery capacities.

These battery figures, if accurate, would build upon the iPhone 17 Pro Max's already strong battery performance. Apple's upcoming A20 Pro chip is also expected to contribute to overall efficiency gains. The source of these leaks is somewhat murky, pointing to social media posts with unclear origins.

However, the timing of these leaks coincides with a reported data breach at Apple supplier Tata Electronics. While a direct link isn't confirmed, the possibility that these battery specifications emerged from that breach lends them some plausible credibility. Should these numbers hold true, the iPhone 18 Pro Max could offer impressive longevity.
