Apple debuts new iPhones, updates Apple Watch

As expected, Apple revamped its high-end phone line with a new iPhone Xs and a larger-screen iPhone Xs Max as well as a colorful new lower-cost model, the iPhone Xr. It also updated the Apple Watch featuring a larger screen, fall detection and the ability to take an electrocardiogram.

Why it matters: Apple is the world's most valuable company and the iPhone its most important product. While the phone updates were modest and largely expected, they could be enough to drive many people to upgrade. Meanwhile, new health features could make Apple Watch more compelling.

What's been announced so far:

iPhone Xs and Xs Max

• New A12 bionic processor featuring 6-core processor, 4-core graphics chip and an improved 8-core neural engine. Thinner 7-nanometer wiring means better performance with improved battery life.
• Improved rear and front cameras, including larger sensor on the main camera.
• Ability to adjust depth of field after photo was taken.
• Up to 30 minutes more battery life for iPhone Xs over iPhone X and iPhone Xs Max has an hour and a half more battery life.

Apple Watch Series 4

• The Series 4 has 30% larger screens and a thinner case
• Speaker is 50% louder
• New dual-core, 64-bit S4 chip (i.e. more processing power for up to two times better performance.)

• An improved accelerometer and gyroscope allows the Series 4 watch to identify falls and summon help.
• A new electrical heart sensor allows the Apple Watch to perform an electrocardiogram (ECG). (Feature has FDA approval and coming to US customers later this year)
• Same "all-day" battery life rated by Apple at 18-hours.
• Will be available in three aluminum features as well as stainless steel options, starting at $399, ($499 for the cellular-equipped model).

Also:

• Software updates to Apple TV and Homepod coming on Monday

The bottom line: Adding health features like fall detection and improved heart monitoring is probably the best way for Apple to turn the Apple Watch from a nice-to-have product into a must-wear. The phone updates were largely as rumored, but still take the iPhone X approach to more segments of the market.
