  1. When compared to Galaxy Watch4 battery capacity. The typical capacity has been tested under third party laboratory conditions. The typical capacity is the estimated average capacity considering the deviation in battery capacity among the battery samples tested under the IEC 61960-3 standard. The rated capacity is 573mAh for Galaxy Watch5 Pro, 398mAh for Galaxy Watch5 Large, and 276mAh for Galaxy Watch5 Small. Actual battery life may vary depending on the network environment, usage patterns, and other factors.
  2. Requires Samsung Health application version 6.22.1 or later. The Galaxy Watch5 must be paired with a Samsung Galaxy phone with Android 8.0 and minimum 1.5GB RAM.
  3. Intended for general wellness and fitness purposes only. Not intended for use in detection, diagnosis, treatment of any medical condition or sleep disorder. The measurements are for your personal reference only. Please consult a medical professional for advice. DO NOT measure your body composition if you are pregnant, have an implanted pacemaker or other implanted medical devices. Due to country restrictions in obtaining approval/registration as a medical device for certain services, those sensor(s) and their relevant service(s) may not be available for use.
  4. ECG feature is not intended for users under 22 years old and not intended to replace traditional methods of diagnosis or treatment. Users should not interpret or take clinical action based on the device output without consultation of a qualified healthcare professional. Requires a Galaxy smartphone running Android 7.0 or above. ECG availability may vary by country or region. Due to country restrictions in obtaining approval/registration as a medical device, ECG only works on watches and smartphones purchased in the countries where service is currently available (however, service may be restricted when users travel to non-service countries).For accurate BP readings, a calibration is required every 4 weeks by BP monitor & arm cuff. Users should measure their blood pressure when at rest, as they would do with a traditional cuff, and refrain from measuring when they are working out, smoking, or drinking. The BP app is not intended for any diagnostic purposes regarding hypertension or other heart conditions.
  5. Testing conducted by Samsung in June 2022 using pre-released version of Galaxy Watch 5 (BT & LTE), each paired to a Samsung phone; all devices tested with prerelease software, Galaxy Watch Magnetic Fast Charging USB C Cable (EP-OR900), and Samsung 25W USB C Power Adapter (EP-TA800). Charge time varies with region, settings, usage pattern and environmental factors; actual results may vary. Additionally, in order to experience faster charging, you need the wireless charger (EP-OR900) and TA(EP-TA800, EP-TA845, EP-TA45E, EP-TA210, EP-T1510) that supports 5V/2A or higher and PD supports faster charging.
  6. Samsung 25W USB C Power Adapter (EP-TA800) is sold separately.

It is not suitable for diving or high-pressure water activities. If the device or your hands are wet, they must be dried thoroughly prior to handling.
  8. Google Assistant for watch is a downloadable app. Default voice assistant is Bixby.
  9. Requires an internet connection. Compatible with Galaxy Watch in Wear OS powered by Samsung.
  10. Bands are sold separately.
  11. BP availability may vary by country or region. Due to country restrictions in obtaining approval/registration as a medical device, BP only works on watches and smartphones purchased in the countries where service is currently available (however, service may be restricted when users travel to non-service countries). Check out https://www.samsung.com/apps/samsung-health-monitor for more information and latest update on service countries.
