Samsung Galaxy Watch8 LTE 44mm

The Samsung Galaxy Watch8 is built around a 46 x 43.7 mm case that measures just 8.6 mm thick and weighs 34 g, giving it a slim and lightweight profile on the wrist. Its 1.47″ OLED/AMOLED touchscreen delivers a 480 x 480 px resolution at 327 ppi, protected by sapphire glass and equipped with an always-on display mode. The watch band is replaceable and measures 20 mm in width, while the case volume sits at 17.28 cm³. Water resistance is rated at 5 ATM and IP68, covering a waterproof depth of 50 m, making it suitable for swimming and similar water exposure. The watch does not feature branded damage-resistant glass such as Gorilla Glass. Operating temperatures range from 0 °C at the lower end to a maximum of 35 °C.

The Samsung Galaxy Watch8 carries a thorough sensor suite designed to support both health monitoring and physical activity tracking. Core biometric sensors include a heart rate monitor, a pulse oximeter for blood oxygenation readings, and a body temperature sensor. Motion and orientation are handled by an accelerometer, gyroscope, and compass, while a barometer adds environmental pressure readings useful for elevation-based activities. Built-in GPS enables location tracking without relying on a paired phone. The watch does not include a cadence sensor or a perspiration monitor.

The Samsung Galaxy Watch8 covers a wide range of everyday activity tracking, recording steps, distance, pace, and elevation, while a route tracker logs the path taken during outdoor sessions. Automatic activity detection identifies workouts without manual input, and exercise tagging allows users to label specific sessions for easier review. Sleep tracking is supported alongside detailed sleep reports, giving a clearer picture of rest patterns over time. For water-based activities, the watch includes a swim stroke counter and also tracks calorie intake as part of its broader health monitoring. It does not include a dedicated multi-sport mode and is not designed for diving or golf.

The Samsung Galaxy Watch8 includes a cellular module with a single eSIM, allowing it to operate independently from a paired phone for calls and data. It is compatible with Android devices only and does not support iOS. Wireless connectivity is handled through Bluetooth 5.3 and Wi-Fi 4 (802.11n), while NFC is also present for contactless interactions. Satellite navigation extends to Galileo support alongside the built-in GPS. ANT+ is not supported on this model.

The Samsung Galaxy Watch8 is powered by a built-in 435 mAh rechargeable battery rated for up to 2 days of use on a single charge. It supports wireless charging, removing the need for a physical cable connection. The battery is not removable and the watch does not offer solar charging as an alternative power source.

The Samsung Galaxy Watch8 offers an extensive set of health and smart features centered around cardiac monitoring, including ECG technology, HRV tracking, VO2 max measurement, resting heart rate tracking, and alerts for fast, slow, or irregular heart rhythms. A readiness and recovery indicator gives users a daily snapshot of their overall physical state, while fall detection adds a layer of personal safety. On the communication side, the watch can answer calls directly from the wrist, handle call control, deliver wrist notifications, and respond to voice commands. Practical utilities include a stopwatch, silent alarm, vibrating alerts, a phone-finding function, and a remote camera shutter trigger. Fast GPS lock reduces the time needed to acquire a satellite signal before outdoor sessions. The watch is backed by 2 GB of RAM and 32 GB of internal storage, though it does not feature a smart alarm.

The companion app for the Samsung Galaxy Watch8 is available free of charge and operates without advertisements. It covers a broad range of health and lifestyle logging tools, including a food diary, water intake tracking, weight tracking, and BMI monitoring, alongside calorie burn counting and temperature tracking. Activity-focused features include an exercise diary, activity reports, route support with maps, inactivity alerts, goal setting, and voice feedback during workouts, with music playback also supported. Menstrual health is addressed through period notifications and cycle start date prediction. The app supports widgets, personalisation, and achievements to encourage ongoing engagement. Coaching guidance is built in, and the experience can be tailored to individual preferences. A barcode scanner for food logging is not included.

The Samsung Galaxy Watch8 includes a battery level indicator, auto pause for workout sessions, and passcode protection for added security. It is compatible with smart scales and external heart rate monitors, allowing it to integrate with a broader ecosystem of health peripherals. The watch does not support Windows or Mac OS X, has no external memory slot, and does not include a 3.5 mm audio jack.
