Notes

1. The battery life may vary according to the settings, operation conditions and other factors. So the actual result may differ from the laboratory data.

Typical usage scenario: Heart rate monitoring is always on and measures at 10-minute intervals, sleep monitoring enabled; 150 pushed messages a day; receive 3 call notifications per day; raise wrist to see watch time 100 times; test blood-oxygen 5 times per day; bright screen operations for 5 minutes per day; exercise 3 times a week with GPS running for 30 minutes each time.

Battery Saver Mode: Engage the Battery Saver Mode on the watch, which turns off the Bluetooth connection, heart rate and other functions, and only records steps and basic sleep information.

Heavy usage scenario: Heart rate monitoring is always on and measures at 1-minute intervals, sleep monitoring enabled with 8 hours of sleep breathing quality monitoring, stress monitoring enabled; 150 pushed messages a day lighting up the screen display; receive 3 call notifications per day; raise wrist to see watch time 100 times; test blood-oxygen 5 times per day; bright screen operations for 15 minutes per day; exercise 3 times a week with GPS running for 30 minutes each time.

2. Always-on Display: When the screen is illuminated, it displays system content. When the screen is in standby mode, it displays the time. This function requires users to manually set "Always-on Display". The user can switch on or off this feature through the watch or Zepp App.

3. The accuracy and sensitivity of the workout recognition feature varies from person to person, and are related to the posture and proficiency of the user during their workout. Short workout duration or frequent changes in posture may not trigger the automatic recognition feature. When you are driving a car or taking a bus, or taking part in other such activities, accidental recognition may be triggered if these activities are particularly similar to the selected workout mode. When you are conducting outdoor activities, if the GPS signal is poor or the AGPS data information has not been synchronized with the mobile phone for an extended period, these outdoor activities may be assessed as indoor activities.

4. The Virtual Pacer is only compatible with Outdoor Running and Treadmill sports modes.

5. According to the ISO 22810-2010 standard, the Amazfit GTS 4 Mini achieves a rating of 5 ATM, for a water-resistance of up to 50 meters, and is therefore suitable for splashes, snow, showering, swimming, or some high-speed water sports. It has passed third-party testing conducted by SGS, and the report number is SWT2205-06. Remove the watch when taking a hot shower or trip to the sauna, since too much steam can affect the seal and make it less water-resistant in future. Do not wear the watch with a leather or metal strap when swimming - when preparing to swim, change to a fluoroelastomer strap or other suitable type. For more information, please visit the support page at: support.amazfit.com

6. Indoor positioning services are not supported. Positioning speed and accuracy may be affected by the surrounding environment. The number of satellites connected to simultaneously, and specific satellite connections, may depend on your location.

7. This product and the Zepp App are not medical devices and cannot be used for medical purposes, or as basis for diagnosis of any medical condition. Detection results are provided for reference only. Please consult professional medical institutions if you feel unwell.

8. 24-hour monitoring of heart rate and blood-oxygen saturation (SpO₂) need to be enabled in the Zepp App. For heart rate monitoring, the user must enable Auto Heart Rate Monitor in the Zepp App, and the minimum value can be set to 1 minute. Abnormal heart rate alerts and the preset value need to be set in the Zepp App. To measure blood-oxygen saturation (SpO₂), please wear the watch tightly at one finger-width from the wrist, and keep your arm still for best results. SpO₂ alerts are sent if the detected rate is too low compared to the preset value, which needs to be set in the Zepp App, at a minimum of 80%. Movement, and environmental and physical characteristics can affect speed and accuracy of monitoring and measurement. The 24-hour stress level monitoring needs to be enabled on the watch or in the Zepp App. Alerts for high stress levels are based on the preset value, and prompts for the breathing exercise need to be enabled on the watch.

9. To process the one-tap measurement and other manual metric measurements, please wear the watch tightly at one finger-width from the wrist, and keep your arm still for best results. Movement, and environmental and physical characteristics can affect speed and accuracy of monitoring and measurement.

10. Alerts and reminders need to be enabled in the watch settings or Zepp App.

11. Sleep monitoring can record night sleep and naps that last more than 20 minutes. Sleep Breathing Quality tracking needs to be enabled in the Zepp App or in the settings of the watch's Sleep feature.

12. The HUNT Fitness Study indicates that people who maintain a PAI score of 100 or higher show lower risk of hypertension, heart disease, and type-2 diabetes. HUNT Fitness Study: This study was conducted by Professor Ulrik Wisloff of the Faculty of Medicine, Norwegian University of Science and Technology. It lasted for more than 35 years and had more than 230,000 participants. To use this function, all-day heart rate monitoring must be enabled.

13. Alexa will be available via OTA update. To see the full list of 15 countries/regions and 14 languages supported, as well as how to activate and use Alexa on your Amazfit GTS 4 Mini, please visit support.amazfit.com.

14. This feature is only supported by Android devices with Zepp App version 6.10.0 or higher version installed.
