Apple's upcoming iPhone 17 Pro Max is rumored to feature a massive 5000 mAh battery, a 7% increase over its predecessor and the largest ever in an iPhone. This contrasts with the slimmer iPhone 17 Air, expected to have a smaller 2800 mAh battery. The larger battery will likely result in increased thickness and weight, but promises significantly improved battery life. The iPhone 17 series is anticipated for release in September.
