Introducing a revolutionary Blood Oxygen feature, Apple announced Apple Watch Series 6, which gives users even more insight into their overall wellness. In addition to its colorful lineup, Apple Watch Series 6 delivers many notable hardware improvements including faster S6 System in Package (SiP) and a new generation altimeter with a wide range of new finishes and bands. watchOS 7 provides Family Setup, sleep tracking, automatic detection of hand-wash, new types of workouts, curating and sharing of watches, encouraging customers to be more active, connected, and better health management.
“Apple Watch Series 6 completely redefines what a watch can do,” said Jeff Williams, Apple’s chief operating officer. “With powerful new features, including a Blood Oxygen sensor and app,1 Apple Watch becomes even more indispensable by providing further insight into overall well-being.”
Series 6 expands Apple Watch’s health skills to include a new feature that conveniently measures the oxygen saturation of the user’s blood and enhances their general fitness and wellness. Oxygen saturation, or SpO2, represents the oxygen portion of the red blood cells transmitted from the lungs to the rest of the body and shows how well this oxygenated blood is delivered throughout the body.
In order to compensate for natural skin changes and increase accuracy, the Blood Oxygen Sensor uses four clusters of green, red, and infrared LEDs together with four photodiodes on the Apple Watch rear crystal for measuring light from the blood reflected back. The advanced customized algorithm included in the Blood Oxygen app is then used by Apple Watch to measure blood oxygen between 70 and 100 percent. Measurements on demand may be taken while the user is still in operation and regular background measurements occur when inactive even while sleeping. All data are seen in the health app and over time the user will be able to monitor trends in their blood oxygen levels.
Apple is working with researchers to conduct health studies using Apple Watch to investigate how the levels of blood oxygen can be used in future health applications. This year, Apple will work with the University of California, Irvine, and Anthem to examine how longitudinal blood oxygen and other physiological signals can help manage and control asthma.
Apple Watch Series 6 improves performance in terms of redesigned hardware that packages even more functionality and power into an impressively small design. The upgraded S6 SiP runs up to 20 percent faster using a new dual-core processor based on the iPhone A13 Bionic, which enables apps to also run 20% faster while maintaining the same battery life throughout the day. Additionally, the 6 Series features the U1 chip and the Ultra-Wideband antennas, which provide short-range wireless location support for new experiences, for example, next-generation digital car key. Apple Watch Series 6 provides faster charging, completing a full charge of fewer than 1.5 hours, and improving battery life to track certain training courses, such as indoor and outdoor runs.
An improved Always-On Retina display in the Apple Watch Series 6 is up to 2.5 times brighter when the user has a wrist down, making it much easier to view the watch face in bright sunlight. When the wrist is down, the user can now also access the Notification Center and the Control Center, click on the complications, and swipe faces without waking the display.
The always-on altimeter offers real-time elevation throughout the day, together with GPS and Wi-Fi, with a new, efficient barometric altimeter. This feature detects small changes in height above ground level up to 1 foot and shows a new watch face complication or workout metric.
