Samsung Galaxy Watch Ultra2 47mm LTE Smartwatch – 800mAh Battery

Product Description

The Samsung Galaxy Watch Ultra2 47mm LTE is built for trail running, cycling, open-water activities and users who need longer battery life from an Android smartwatch. Its shock-resistant titanium case combines a distinctive cushion-shaped design with a large circular display, three separated side buttons and a programmable Quick Button.

A 1.52-inch Super AMOLED display delivers a sharp 498 × 498 resolution and brightness of up to 5,000 nits. Workout statistics, routes, heart-rate zones and notifications remain easier to read in direct sunlight and underwater. Sapphire Crystal protects the screen against everyday scratches and outdoor wear.

The watch is powered by the Snapdragon Wear Elite 3nm processor with 2GB RAM and 64GB storage. This combination supports responsive app performance, detailed workout tracking, offline music and Wear OS applications.

Product Specifications

800mAh Battery with Fast Charging

The Galaxy Watch Ultra2 contains the largest battery currently offered in a Galaxy Watch. Its 800mAh battery provides up to 60 hours of use with the Always-On Display enabled.

Fast Charging can restore approximately 40% battery in 30 minutes, while a complete charge takes around 90 minutes under Samsung’s test conditions. Actual battery life depends on LTE, GPS, display brightness, health monitoring and application use.

Trail Running and Route Guidance

Galaxy Watch Ultra2 is designed to provide more than basic step and distance tracking. Users can load compatible GPX routes and follow turn-by-turn directions while built-in GPS monitors their location.

Climb Guidance shows upcoming elevation gain and average gradient, helping runners manage their effort before reaching steep sections. Water Intake Alarm provides hydration reminders during longer trail sessions, while Track Back can guide users along their previous route.

Dual-frequency L1 and L5 GPS improves positioning for runs, hikes and cycling routes in areas where buildings, trees or difficult terrain can interfere with standard GPS signals.

Cycling Performance Tools

Cyclists can view speed, cadence, power and heart-rate information from the wrist. The watch can connect directly to compatible cycling sensors without requiring the phone between the watch and sensor.

Users can also compare a current ride against a previous performance, follow GPX cycling routes and monitor personalized heart-rate zones during training.

Diving and Water Resistance

The Galaxy Watch Ultra2 carries 10ATM, IP69K, MIL-STD-810H and EN13319 certifications. It can automatically display selected underwater information, including current depth, water temperature and elapsed dive time.

Samsung states that the watch supports recreational underwater use down to 40 metres under applicable conditions. Water resistance is not permanent, so the watch should be rinsed and dried after exposure to seawater or chlorinated water.

Health and Fitness Tracking

Samsung’s BioActive Sensor supports heart-rate monitoring, electrical heart-signal measurements and bioelectrical impedance analysis. The watch also includes temperature, barometer, accelerometer, gyroscope and light sensors.

Samsung Health provides access to more than 100 workout programs. Fitness Index evaluates selected fitness information, while Daily Cardio Load helps users compare training effort with recovery needs.

Sleep tracking monitors sleep patterns and heart signals, while Energy Score combines recent sleep, activity and heart data to provide a daily readiness estimate. Sleep Coaching uses several nights of information to suggest more consistent sleep habits.

Some ECG, sleep-apnea, blood-pressure and heart-health functions depend on country approval and a compatible Samsung phone. Health features are intended for general wellness and do not replace medical diagnosis.

LTE, Smart Apps and Safety Features

Built-in LTE allows compatible calls, messages and mobile services to work without keeping the paired smartphone nearby. Carrier activation and eSIM availability vary by region.

The watch also supports Bluetooth 6.0, dual-band Wi-Fi, NFC and dual-frequency GPS. Wear OS 7 with One UI 9 Watch provides access to compatible applications such as Google Maps, Spotify, Gmail, Google Messages, YouTube Music, Strava and Samsung Health.

Outdoor safety tools include Fall Detection, Emergency SOS and an 86-decibel siren designed to be heard from up to 180 metres under suitable conditions.
