Apple Introduced the iPhone Air and iPhone 17

The new iPhone lineup includes four new phones: the iPhone Air, 17, 17 Pro, and 17 Pro Max.

Apple revealed its highly anticipated $999 iPhone Air, the "thinnest iPhone ever" — at 5.6 millimeters, it's the slimmest iPhone yet. Apple also claims that the 6.5-inch phone is the most durable of all iPhones and benefits from an improved internal chip. It's the most power-efficient iPhone ever made, with a powerful camera and an all-day battery life.

Meanwhile, the $1,099 iPhone 17 Pro is "the most powerful iPhone yet, by far," according to Apple. The phone has a unified outer body that uniformly dissipates heat from the battery, preventing overheating. Apple also said that the phone offers "the best battery life ever in an iPhone," with 39 hours of video playback.

Apple said the event was filmed with an iPhone 17 Pro, demonstrating the capabilities of the phone in real time. The $1,199 iPhone 17 Pro Max has a larger screen than the Pro, but features the same capabilities, including increased power and battery life.

The standard iPhone 17 features a 6.3-inch display with thinner borders for a wider screen. The display is more readable in direct sunlight, and the phone has twice the scratch resistance. Charging is now faster than ever: Ten minutes of charge can result in 8 hours of video playback.

iPhone cameras are also improving, with better resolution and a wide field of view for the front-facing camera. Apple noted that users took 500 billion selfies last year, more than any other smartphone.

Pre-orders for the new iPhone lineup start Sept. 12. The new phones will be available starting Sept. 19.

What's New With the AirPods Pro 3

Cook said that this year, Apple was building on innovations with AirPods Pro, including the hearing aid function introduced last year that transformed the buds into assistive devices for people experiencing mild to moderate hearing loss.

At the event, Julz Arney, senior director of fitness technologies at Apple, introduced heart rate sensing for AirPods. Custom sensors on the AirPods allow the earbuds to track heart rate independently of a smartwatch, Arney explained.

The AirPods Pro 3 also deliver twice the active noise cancellation of previous generations. Apple claimed that the AirPods deliver the world's best active noise cancellation of any in-ear headphones.

The earbuds also offer live translation, transforming words from one language into another in real-time. For example, if someone speaks a different language, the AirPods will lower their voice and deliver a real-time translation.

The AirPods Pro 3 cost $249 and will be available on Sept. 19. Preorders begin Tuesday.

Here's How the Apple Watch Is Changing

Apple introduced the $399 Apple Watch Series 11, which comes with a thorough list of health features, including state-of-mind tracking for mental health.

In a new development, Apple is taking on hypertension, or high blood pressure, with a new feature that tracks irregularities in blood pressure over time. Apple expects to notify one million people of hypertension within the first year alone.

The company is also introducing a new sleep score based on duration of sleep, how many times a user wakes up throughout the night, and regularity of sleep over time. The new sleep score function applies to the budget-friendly $249 Apple Watch SE 3.

The $799 Apple Watch Ultra 3 is also packed with new features, including satellite connectivity. Even when a user is off the grid, they can use their Apple Watch to get help in case of an emergency. The watch features 42 hours of battery life and also has hypertension notifications.
