Leaked information indicates that the upcoming iPhone 17 Pro Max will feature a 5000 mAh battery, marking the largest battery capacity ever included in an Apple iPhone. This represents an increase from the 4676 mAh battery found in the iPhone 16 Pro Max. The enhanced battery capacity is expected to provide a battery life of at least 35 hours, surpassing previous iPhone models.
