Apple’s upcoming iPhone 17 Pro Max is rumored to feature the largest battery ever in an iPhone, with a capacity of approximately 5,000mAh according to Chinese leaker ‘Instant Digital’ on Weibo. This would represent a significant 10% increase from the iPhone 16 Pro Max’s 4,676mAh battery. The larger battery comes as part of rumors suggesting the iPhone 17 Pro Max will be slightly thicker and heavier than its predecessor to accommodate the increased capacity. The device is expected to launch in September 2025 with other significant upgrades including new MagSafe magnet layouts and a redesigned camera system. While battery capacity doesn’t have a 1:1 correlation with battery life improvements, this upgrade could substantially improve the device’s endurance for power users.
