Samsung Galaxy Watch4, Watch4 Classic are First to Feature the New Wear OS

Samsung has added a pair of new smartwatches to its line-up, the Galaxy Watch4 and Galaxy Watch4 Classic, both of which are the first to feature the new Wear OS powered by Samsung, which was built in collaboration with Google, and come equipped with One UI for a more intuitive interface.

The Galaxy Watch4 is equipped with Samsung’s BioActive Sensor, which boasts a smaller and more compact design that doesn’t detract from measurement accuracy. This new sensor uses a single chip to run sensors such as Optical Heart Rate and Bioelectrical Impedance Analysis so wearers can monitor their heart rate, blood oxygen level, and for the first time, calculate body mass composition.

The new Body Composition measurement tool gives users a deeper understanding of their general wellness and fitness, with key measurements like skeletal muscle mass, basal metabolic rate, body water, and body fat percentage. To check body composition, just place two fingers on the device while it’s on your wrist and in about 15 seconds, the sensor will capture 2,400 data points.

Choose from a wide range of guided workouts, enjoy Group Challenges with your friends and family, or set up a home gym by connecting your Galaxy Watch4 to a compatible Samsung Smart TV, where calorie counts and heart rate metrics appear on screen for easier tracking. At night, the Galaxy Watch4 also tracks detailed sleep with Sleep Score as well as blood oxygen level.

With One UI Watch, settings like do not disturb hours and blocked callers are synced instantly. Auto Switch ensures your earbuds can toggle audio between your phone and watch, depending on usage. You can also control your mobile experience with Bixby voice, bezel, and Gesture Controls. Move your forearm up and down twice to receive calls and rotate your wrist twice to reject them, or to dismiss notifications and alarms.

The Galaxy Watch4 series is also the first generation of smartwatches to feature Wear OS Powered by Samsung, which affords access to popular Google apps like Google Maps and Galaxy services like Samsung Pay, SmartThings, and Bixby. The new platform also includes support for third-party apps, like Adidas Running, Calm, Strava, and Spotify, available from Google Play. An enhanced built-in compass that works in tandem with Google Maps to make it easy to explore a new area is one example of many seamless experiences with the new OS.

Galaxy Watch4 lifestyle

Galaxy Watch4 series boasts the first 5nm processor in a Galaxy Watch with 20% faster CPU and 50% more RAM, and a GPU 10 times faster than the previous generation of Samsung smartwatches, says the company. The display resolution is up to 450 x 450 pixels. With 16GB of memory, there’s enough storage to download and store apps, music, and photos with the Samsung Knox security platform.

The Watch4 lasts for up to 40 hours per charge, which means you’ll need to charge it daily, or even two days or so. You can, however, do a quick 30-minute charge to get an extra 10 hours of battery life when needed in a pinch.

“We have seen an incredible amount of growth for the Galaxy Watch series as consumers have discovered the health benefits and convenience of wearables,” says Dr. TM Roh, President and Head of Mobile Communication Business, Samsung Electronics. “We understand the path to health is different for everyone, so we built a robust suite of health and wellness features to give people a deeper and more helpful understanding of their overall fitness.”
