Typical value tested under third party laboratory condition. Typical value is the estimated average value considering the deviation in battery capacity among the battery samples tested under IEC 61960 standard. Typical capacity is 800 mAh for Galaxy Watch Ultra2 (35 % increase compared to previous Galaxy Watch Ultra) and typical capacity for Galaxy Watch Ultra is 590mAh. Actual battery life may vary depending on network environment, usage patterns and other factors.

The 5,000-nit specification refers to the localised peak brightness achieved under high ambient light, and full-screen brightness may differ. Actual brightness may vary or be limited depending on environmental factors, device temperature, and usage conditions.

Galaxy Watch Ultra2 has a water resistance rating of 100 meters according to the ISO22810 standard. The test was conducted in 5 % salt water and 4 ppm chlorine water. Galaxy Watch Ultra2 is also water resistant with an IPX8 rating based on the lab test conditions for submersion in up to 1.5 meters of freshwater for up to 30 minutes and an IPX9K rating based on the lab test conditions for water resistance against powerful water jets. Galaxy Watch Ultra2 has obtained EN13319, which is a standard applicable to instruments measuring water depth by the environmental pressure as used by divers and also the dive time in certain condition. Water resistance is not a permanent condition and can diminish over time. If it's been exposed to seawater, rinse it in freshwater and dry after use. Refer to the user manual for further information, including care/use instructions. Galaxy Watch Ultra2 is dust resistant with an IP6X rating based on the lab test conditions by a third party: 2 kg of talc powder (max. diameter of 0.05 mm) per cubic meter was blown into a test chamber housing the device (air pressure within device kept below surrounding air) for 2 hours. Dust resistance may vary by actual usage conditions. Galaxy Watch Ultra2 has obtained MIL-STD-810H Certification: high/low temperature, altitude, humidity, immersion, salt fog, dust, vibration, drop, etc. MIL-STD-810H is a standardised form of testing designed by the U.S. Military to accurately assess device limitations. Real world usage may vary by specific environmental conditions used in the testing. Extreme conditions not guaranteed. Galaxy Watch Ultra2 withstands temperatures ranging from -20°C to 55°C while being worn on the wrist, based on results from internal lab tests conducted by Samsung. Actual performance may vary depending on the environment where it is used. In very high or low temperatures, charging may be blocked, certain functions may be automatically terminated or unavailable, or the watch may shut down automatically for safety. Additionally, battery performance can be adversely affected at low temperatures.
