Apple’s upcoming iPhone 17 Pro Max is generating significant buzz ahead of its expected September 2025 launch, largely due to its anticipated record-breaking battery capacity. According to multiple credible leaks and industry sources, the iPhone 17 Pro Max will feature the largest battery ever fitted to an iPhone, a move designed to deliver the longest battery life yet for Apple’s flagship device.
With a 4,800mAh battery, users can expect up to 28 hours of video playback—about 15% more than the previous generation. The device is engineered for all-day use, even with heavy multitasking, gaming, 8K video recording, and AI-powered features. Advanced power management, including a rumored AI-based battery optimization system, will further enhance efficiency and longevity.
Fast wired charging: Up to 35W USB-C Power Delivery, reaching 50% charge in about 20 minutes.
MagSafe wireless charging: 15W for convenient cable-free top-ups.
Reverse wireless charging: 5W, allowing users to charge accessories like AirPods or other compatible devices directly from the iPhone.
Apple’s pivot to a “battery-first” design philosophy for the iPhone 17 Pro Max is a direct response to user demand for longer endurance, particularly among power users who rely on their phones for intensive tasks throughout the day.
