Leaker Instant Digital claims the iPhone 17 Pro Max will boast a massive 5,000mAh battery, a significant upgrade from the iPhone 16 Pro Max's 4,676mAh. This could potentially result in approximately 35 hours of battery life, exceeding the iPhone 16 Pro Max's 33 hours. Improved efficiency from the A19 Pro chip and Snapdragon X80 modem will also contribute. While Instant Digital's accuracy is inconsistent, their past successes lend credibility to this prediction.
