Samsung describes that as a 35 per cent increase. The supplied material gives battery capacity rather than a runtime estimate, leaving endurance for measured testing.SpecificationSamsung Galaxy Watch Ultra 2Samsung Galaxy Watch UltraWhat changedLaunch year20262024Two-year gapCase size47mm47mmSame nominal sizeDimensions47.4 × 47.1 × 10.7mm47.4 × 47.4 × 12.1mm1.4mm thinner; width reduced by 0.3mmWeight61.5g60.5gUltra 2 is 1g heavierDisplay1.52-inch Super AMOLED, 498 × 498, up to 5,000 nits1.5-inch Super AMOLED, 480 × 480, up to 3,000 nitsLarger, higher resolution and 2,000 nits brighter at peakCoverSapphire CrystalSapphire CrystalRetainedProcessorQualcomm SDW6100, 3nm, penta-coreExynos W1000, 3nmQualcomm replaces ExynosMemory2GB RAM2GB RAMRetainedStorage64GB32GBDoubledBattery800mAh590mAhSamsung claims a 35 per cent increaseSoftwareWear OS 7, One UI 9 WatchWear OS, One UI WatchNew software generationGPSL1+L5 dual-frequencyL1+L5 dual-frequencyRetainedListed protection10ATM/10ATM+, IP69K, MIL-STD-810H, EN1331910ATM, IP68, MIL-STD-810HIP69K and EN13319 addedSpecificationSamsung Galaxy Watch Ultra 2Samsung Galaxy Watch UltraLaunch year20262024Case size47mm47mmDimensions47.4 × 47.1 × 10.7mm47.4 × 47.4 × 12.1mmWeight61.5g60.5gDisplay1.52-inch Super AMOLED, 498 × 498, up to 5,000 nits1.5-inch Super AMOLED, 480 × 480, up to 3,000 nitsCoverSapphire CrystalSapphire CrystalProcessorQualcomm SDW6100, 3nm, penta-coreExynos W1000, 3nmMemory2GB RAM2GB RAMStorage64GB32GBBattery800mAh590mAhSoftwareWear OS 7, One UI 9 WatchWear OS, One UI WatchGPSL1+L5 dual-frequencyL1+L5 dual-frequencyListed protection10ATM/10ATM+, IP69K, MIL-STD-810H, EN1331910ATM, IP68, MIL-STD-810HSensorsBioActive Sensor, temperature, accelerometer, barometer, gyro, geomagnetic and light sensorsBioActive Sensor, temperature, accelerometer, barometer, gyro and geomagnetic sensorsHow does Galaxy Watch Ultra 2 use AI for health tracking?Samsung says the Galaxy Watch Ultra 2 continuously collects biometric information and uses AI analysis to turn those measurements into personalised guidance and timely alerts. The mechanism described in the launch material is a sequence: sensors collect daily health readings, software interprets changes and the watch presents an alert or recommendation.The company places this approach within a move towards preventive wellness, where the watch builds a day-long record from repeated measurements.TM Roh, Samsung's CEO and head of the Device eXperience division, linked the new Galaxy Watch line with the company's wider connected-health work. The supplied material paraphrases his position and provides zero direct quotation, so this article retains it as an attributed company claim.More articles by AuthorTrending StoriesThe launch copy gives a broad description of continuous tracking and AI interpretation. It supplies more detail for the sport-specific functions, where the input and intended output are easier to identify.What does Trail Run track?Trail Run records elevation changes, climbing progress and the effect of terrain during a route. Samsung says those measurements help runners manage pace across climbs and changing ground.Nutrition Alert addresses hydration. It uses estimated sweat loss relative to body weight to suggest when and how much water the wearer may need during endurance activity. The function works with Samsung's existing Sweat Loss monitoring.The two tools solve different problems. Trail Run describes the route and effort. Nutrition Alert uses the body's estimated fluid loss to provide hydration guidance. Samsung presents both as planning and safety aids for prolonged outdoor exercise.How do the Galaxy Watch Ultra 2 diving features work?The Galaxy Watch Ultra 2 automatically tracks depth, dive duration and water temperature after the wearer enters the water. Samsung developed its diving functions with Mares, a company specialising in underwater equipment.Further functions will arrive through the Ultra 2 Diving app later in 2026. Samsung lists ascent speed, descent speed and safe dive limits among the coming additions. Their release timing is stated only as later this year in the supplied material.The watch carries IP69K protection, MIL-STD-810H and EN13319 listings. Samsung's launch copy describes 10ATM water resistance, while the supplied specification table lists 10ATM+. That discrepancy needs confirmation before publication; the comparison table above preserves both forms.These additions push the Ultra 2 beyond general workout logging into specialised trail and underwater use. The value depends on reliable measurements in conditions where depth, temperature, terrain and hydration can change quickly—an assessment that requires field testing.Why does the larger battery matter?An 800mAh battery gives Samsung 210mAh more capacity than the first Galaxy Watch Ultra. It supports a device intended for continuous health monitoring, GPS-tracked endurance exercise and diving.Capacity alone gives an incomplete endurance verdict because the Snapdragon processor, 5,000-nit display, radios, sensors and software all affect consumption. Samsung's supplied information provides the cell size and 35 per cent increase while leaving runtime and charging figures pending.The physical engineering is easier to measure. Ultra 2 thickness falls from 12.1mm to 10.7mm, a reduction of 1.4mm. Samsung rounds that change to 12 per cent. Weight rises from 60.5g to 61.5g, so the new watch is thinner and 1g heavier while carrying 210mAh more battery capacity.How bright is the Galaxy Watch Ultra 2 display?Samsung rates the 1.52-inch Super AMOLED Always-On Display at up to 5,000 nits. The original Galaxy Watch Ultra carried a claimed 3,000-nit peak, giving the Ultra 2 a 2,000-nit increase on the specification sheet.The new resolution is 498 × 498 pixels, up from 480 × 480. Sapphire Crystal protection remains. Samsung says the higher peak brightness is intended to improve visibility in strong outdoor sunlight; sustained brightness and real-world legibility await testing.Processor, storage and connectivityThe Galaxy Watch Ultra 2 uses Qualcomm's SDW6100, a 3nm penta-core processor, replacing Samsung's 3nm Exynos W1000 in the first Ultra. Both generations list 2GB of RAM, while storage doubles to 64GB.The watch runs Wear OS 7 Powered by Samsung with One UI 9 Watch. Connectivity includes LTE, Bluetooth 6.0, Wi-Fi, NFC and L1+L5 dual-frequency GPS.The sensor list covers Samsung's BioActive Sensor, temperature sensor, accelerometer, barometer, gyroscope, geomagnetic sensor and light sensor. The first-generation list in the supplied comparison omits the light sensor.Does the slimmer design change the watch's purpose?Samsung retains a titanium case and 47mm size, keeping the Ultra 2 aimed at outdoor exercise and continuous wear. The company has introduced lighter, softer bands to improve comfort across workouts, daily use and sleep tracking.Dimensions move from 47.4 × 47.4 × 12.1mm to 47.4 × 47.1 × 10.7mm. Samsung attributes the slimmer body to internal engineering changes. The stated aim is a watch that moves among outdoor activity, sport and daily health monitoring on the same wrist.Galaxy Watch Ultra 2 colours, availability and India priceSamsung launched the Galaxy Watch Ultra 2 globally on July 22. The 47mm model comes in Titanium Silver and Titanium Gray. Availability varies by market, carrier and retailer.The Ultra 2's strongest upgrade is the way its physical trade-offs fit together. Samsung adds 210mAh of battery, doubles storage and lifts claimed peak brightness by 2,000 nits while cutting 1.4mm from the case. The remaining test happens away from the specification table: battery endurance, sunlight visibility, biometric consistency and underwater performance across the conditions this watch is built to record.Frequently Asked QuestionsWhen did Samsung launch Galaxy Watch Ultra 2?Samsung launched the Galaxy Watch Ultra 2 globally on July 22, 2026.
