A fresh leak claims Apple’s iPhone 17 Pro Max, launching this September, may feature a record-breaking 5,000mAh battery—surpassing the iPhone 16 Pro Max’s 4,676mAh. The rumor, shared by Chinese leaker Instant Digital on Weibo, aligns with earlier reports of a slightly thicker design (8.725mm vs. 8.25mm) to accommodate the larger cell.
If accurate, the ~10% capacity boost could translate to 35+ hours of usage, up from the iPhone 16 Pro Max’s 33 hours. Apple has steadily improved endurance, with the iPhone 14 Pro Max lasting 29 hours and the iPhone 15 Pro Max hitting 32 hours. However, outlets like 9to5Mac warn that capacity alone doesn’t guarantee longer life, as software and hardware efficiency play key roles.
Analysts note that while new features like vapor chamber cooling may not drain power, other advancements (e.g., brighter displays or AI-driven tasks) could offset gains. Apple Insider’s William Gallagher emphasized that real-world performance hinges on how Apple optimizes the device’s overall design.
With battery life remaining a top user demand, the iPhone 17 Pro Max’s rumored upgrade could be a major selling point. If Apple delivers, it might set a new benchmark for flagship smartphones—just as competitors push their own battery innovations. Stay tuned for official details this fall!
