Overview
- A Weibo leak from Instant Digital suggests the iPhone 17 Pro Max will house about a 5,000 mAh cell, the largest ever in an iPhone.
- That jump from the iPhone 16 Pro Max’s 4,676 mAh represents a roughly 7–10 percent capacity increase over its predecessor.
- Industry schematics indicate Apple will thicken and slightly weighten the chassis to fit the larger battery pack.
- Synergy between the new A19 Pro silicon and iOS 26 power-management features is expected to unlock up to 35 hours of runtime.
- The leak underscores Apple’s steady, year-over-year strategy of boosting Pro Max battery life since the 2019 iPhone 11 Pro Max.
