Apple is set to unveil its iPhone 17 series at an event scheduled for September 9, 2025, according to leaked internal documents from German wireless carriers and multiple industry sources. The new lineup is expected to include the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and the iPhone 17 Air, which is anticipated to be Apple's thinnest phone to date with a remarkably slim battery measuring approximately 2.49mm in thickness—about half the thickness of the iPhone 17 Pro's battery. The iPhone 17 Air's battery capacity is rumored to be around 2,800 to 2,900mAh, similar to that of the iPhone 13, raising questions about its endurance. The iPhone 17 Pro Max is expected to feature a 6.9-inch immersive display, enhanced battery life, and an 8x zoom camera. Additionally, rumors suggest a redesign for the iPhone 17 Pro with a new orange color option and upgraded camera capabilities. Pre-orders for the iPhone 17 series are expected to begin on September 12, with a general market release anticipated on September 19. Alongside the iPhone 17 series, Apple is also preparing to launch the Apple Watch Ultra 3, which will feature a slightly larger 1.98-inch display with slimmer bezels and other major upgrades, as revealed by the iOS 26 beta 5 developer release. Apple has also seeded the fifth developer betas for its milestone operating systems, including iOS 26, iPadOS 26, macOS 26 Tahoe, watchOS 26, tvOS 26, and visionOS 26, ahead of the new product launches.
