About the Samsung Galaxy Watch4

Ken Nail

Better in every way

Samsung's Galaxy Watch4 builds off the success of the Galaxy Watch3 by rolling out the entirely new Wear OS™ platform. Developed in conjunction with Google™, it supports the intuitive One UI Watch interface for easy operation. Supported by speedier internal hardware, it makes the Galaxy Watch4 one of the most seamless and best-connected smartwatch options available. With a variety of finishes and bands and almost infinitely customizable watch faces, you'll look good whether you're hitting the gym or out on the town. 

Samsung Galaxy Watch4

The slim design is packed full of features

Maximum portability

This LTE-equipped Galaxy Watch4 connects to cellular networks independent of your smartphone, providing continual contact for messaging, streaming services, and more. So if you're heading out for a run and don't want to lug your phone along it may be just what you need. A separate data plan is required for your watch to enable LTE.

Get your workout on

Galaxy Watch4 automatically tracks activities like running, cycling, and swimming, so you'll have a comprehensive record of all of your workouts. You'll experience a variety of guided workout options, along with group challenge options you can experience with your workout buddies. And if you have a compatible Samsung Smart TV, you can connect Watch4 for a big-screen workout experience. 

Track your health

Watch4 boasts Samsung's BioAcive Sensor which measures heart rate, monitors blood pressure, detects irregular heartbeats, tracks blood oxygen levels, and even measures body composition. This smartwatch monitors your sleep in detail, including tracking snoring and providing you with a detailed sleep score.

Fitness apps and more

There are many outstanding third-party apps dedicated to helping you improve your fitness and wellness. With Galaxy Watch4 you'll enjoy seamless support for apps like Strava and Calm. And with apps like Google Maps and Samsung Pay, you'll enjoy even more convenience when you're out and about. Thanks to the One UI Watch interface, compatible apps are automatically installed on Watch4 when you download them to your phone.

Stay connected

Samsung Galaxy Watch4 connects seamlessly to your phone via Bluetooth or Wi-Fi for easy access to apps and notifications. You can stream music to your Bluetooth® headphones from streaming services like Spotify, or from music files you store in the 16 GB internal memory. This Samsung's powerful battery will last up to 40 hours on a charge, and you can even top off the power from a compatible Galaxy phone when you're on the go. At the end of the day, put your watch on the included wireless charger and you'll be ready to go tomorrow.

    Product Research


    Overview: The Samsung Galaxy Watch4 is a sleek smartwatch that does much more than tell you the time. It can help you track and reach fitness and health goals by monitoring your activity, sleep, and heart rate. The device has built-in 4G LTE wireless service. It also connects to your smartphone via Bluetooth or Wi-Fi for enhanced functionality through the Galaxy Wearable app. The built-in rechargeable battery lasts approximately 40 hours on a full charge. The Galaxy Watch4 comes with a magnetic wireless charging pad, and is covered by a 1-year warranty.

    Design: The Galaxy Watch4 uses the Wear operating system and user interface with an Exynos W920 processor, 1.5GB RAM and 16GB internal memory. It has a 1.36" Super AMOLED color display with a resolution of 450 x 450 pixels (330 pixels per inch). The device features a silver 44mm aluminum case and a Gorilla Glass DX+ crystal lens, with a silver 20mm (medium/large) sports band. It fits wrists between 5-11/16" and 8-1/16" in circumference. On the back of the unit is a heart rate sensor with eight photodiodes that monitors your heart rate during exercise or for calculating your stress level. The watch also has an accelerometer, gyro, barometer, and ambient light sensor. The Watch4 is water-resistant down to 5 meters depth (ATM5), so you can workout in bad weather or even wear the watch while swimming. The touchscreen responds best to a light touch from the pad of your finger, and recognizes tap, swipe (vertically or horizontally), rotate, and drag actions. Dimensions: Case: Diameter-1.752", Depth-0.466"; Band: Width-0.784" Length-10.1"; Weight-2 ounces.

    Rechargeable Battery: The built-in 361mAh rechargeable battery gives you approximately 40 hours of battery life with typical use. The Watch4 charges wirelessly on the included magnetic charging pad, which can be plugged into a USB port (Type A). No charging time data was given.

    Wireless PowerShare: The Galaxy Watch4 is compatible with Wireless PowerShare, which lets you charge the watch by placing it on the back of select Samsung smartphones. When the watch needs charging, it can charge wirelessly on the back of a Galaxy S20, S20+, S20 Ultra, Z Flip, and other Samsung smartphones. Wireless PowerShare is also possible with other Qi-enabled wireless charging devices.

    4G LTE: This 4G LTE Galaxy Watch4 comes with eSIM that allows you to stay connected when you're not near your phone or Wi-Fi. With 4G LTE, you can make and receive phone calls without your phone, plus install watch faces, apps, and reply to notifications without being connected to your phone via Bluetooth or to a local Wi-Fi network. LTE service is supported by the following carriers: AT&T, T-Mobile, US Cellular, and Verizon. A separate qualifying wireless plan may also be required.

    Bluetooth / Wi-Fi / NFC: The Samsung Galaxy Watch4 is equipped with Bluetooth version 5.0 for connecting the device to your smartphone, or to an optional headset for playing music. It also has Wi-Fi (2.4GHz and 5GHz) for connecting to a local wireless network. The watch can communicate with another device through Near Field Communication (NFC) without connecting to a network. This allows you to make payments or purchases through certain apps, like Samsung Pay.

    Galaxy Wearable App: The Watch4 works hand-in-hand with the Galaxy Wearable app on your smartphone. Using the app you can customize the look of the Watch4 with over 50,000 watch faces with different colors, styles, and the amount of information displayed. The app also helps you locate your Watch4 by making it light up and vibrate. The Galaxy Wearable app is compatible with Android devices 4.3 and up. For iPhone (iOS 9.0 or later), you should download the Galaxy Watch app.

    Wear OS: The Samsung Galaxy Watch4 is the first smartwatch powered by the Wear Operating System by Samsung, which gives you access to all of your favorite apps on your wrist. This includes Google services and apps, a wide selection of music streaming app, and a huge library of health and fitness apps. Wear OS by Samsung also pulls all of your Samsung Galaxy devices together, including Galaxy Buds2.

    Health & Fitness: The Galaxy Watch4 helps you to reach your health and fitness goals by tracking your body composition data and coordinate your workouts. Samsung's new BioActive Sensor gives you a BIA (Bio-electrical Impedance Analysis) measurement which analyzes your body composition--the amount of body fat to lean body mass--to help you manage your health goals. The BioActive Sensor can also measure your ECG in real time so you can detect abnormal heart rates or rhythms. The data can be sent directly to a compatible Galaxy phone and shared with your doctor, if needed. The watch also helps you track your activities, count your steps, check your calories. More than 90 exercises are supported and analyzed to provide fitness scores at the end of your workout. Some activities can be tracked with other individuals so that you can compete with them in the same activity, and send encouraging messages. Galaxy Watch4 also adds Advanced Run Coaching and VO2 Max readings to help you track your cardio levels.

    Sleep Management: The watch can track and analyze your sleep cycles to help you get a better night's rest. While you sleep, the watch tracks how long it takes you to fall asleep, how long you spend in the various sleep stages, and the overall sleep time. Galaxy Watch4 can check your blood oxygen levels, and detect whether or not you are snoring.
