The Amazfit GTS 4 watch meets the ISO 22810-2010 standard, featuring a water resistance rating of 5 ATM, allowing it to withstand depths of up to 50 meters. It is suitable for exposure to water splashes, snow, showering, and swimming, and has been tested by a third party, SGS, under report number SWT2206-14. It is advised to avoid wearing the watch in hot baths or saunas as excessive steam can affect its water resistance. When swimming, it is preferable to use a strap made of fluoroelastomer instead of leather or metal. For more details, you can visit support.amazfit.com.

The live sports data streaming service offers audio broadcasting support in both English and Chinese.

The music storage capacity reaches 2.3GB; this can hold approximately 270-470 songs in MP3 format, considering that each song's size ranges between 5-10MB, with some space allocated for system use.

The reliability of the exercise recognition feature depends on individual differences in posture and skill level during workouts. Rapid or varied movements may not consistently activate the feature. Interaction with activities such as driving or taking a bus could unintentionally trigger recognition if they resemble the specified exercise. Additionally, weak GPS signals or unsynchronized AGPS data during outdoor activities may be misclassified as indoor activities.

Smart recognition of strength training exercises is exclusively available in strength training mode. It supports 25 exercises, including bodyweight and weighted exercises like squats, presses, pulls, push-ups, and curls. If an exercise is not automatically detected by the watch, the Zepp app provides a list of muscle groups or exercise names to choose from.

Indoor positioning services are not available. The speed and accuracy of location determination may be affected by the surrounding environment. The number and type of satellites used may vary depending on your location.

The straight lines leading back to the starting point of the journey may not be a viable path due to environmental conditions; rather, they indicate your location in relation to the starting point. The navigation features support 18 following sports modes: outdoor running, walking, outdoor cycling, climbing, hiking, cross-country skiing, mountain biking, BMX, outdoor boating, bobsledding and sledding, skiing, snowboarding, biathlon, race walking, snowshoeing, trail running, navigation, and open water swimming.

The track operation mode and smart track correction are compatible only with running track lengths of 200 meters and 400 meters.

Interval training templates can be utilized in: outdoor running, treadmill running, outdoor cycling, indoor cycling, jumping rope, rowing machine, indoor fitness exercises, strength training, core muscle training, and stair climbing.

Always-On Display: The system content is shown when the screen is lit, while the time is displayed in standby mode. Users need to manually activate the "Always-On Display" feature, which can be toggled on or off using the watch or the Zepp app.

To enhance heart rate and blood oxygen monitoring in the Zepp app: - Activate 24-hour heart rate and oxygen level monitoring. - Set the heart rate monitor to a minimum tracking time of 1 minute. - Configure alerts for abnormal heart rates with predefined values. - Ensure accurate oxygen measurements by wearing the watch snugly, one finger's width away from the wrist, and keeping your arm steady. - Set alerts for oxygen levels below the specified threshold (minimum 80%). - Consider factors such as movement and environment that may affect monitoring accuracy. - Activate 24-hour stress level monitoring on the watch or app. - Customize alerts for high-stress levels based on predefined values. - Enable breathing exercise notifications on the watch.

This product and the Zepp app are not medical devices and should not be used for medical purposes or as the sole basis for diagnosing any medical conditions. The detection results are for reference only. If you have any health concerns, please consult professional medical institutions.

To achieve accurate results when using manual meter measurements or with a single click, make sure to wear the watch snugly, one finger's breadth away from your wrist. Keep your arm steady to enhance monitoring accuracy, as movement and environmental factors can affect speed and precision.

Sleep tracking can monitor nighttime sleep and naps lasting longer than 20 minutes. To enable tracking of breathing quality during sleep, you can access the Zepp app or adjust the settings within the sleep feature on the watch.

Morning updates must be configured in the Zepp app or watch settings. Supported contents include weather status, battery level, sleep data, schedule, PAI score, menstrual cycle tracking, and yesterday's activity.

The HUNT study on fitness indicates that individuals with a PAI score of 100 or more have a lower likelihood of developing high blood pressure, heart disease, and type 2 diabetes. This research was led by Professor Ulrik Wisløff from the Norwegian University of Science and Technology’s medical school, spanning over 35 years and involving more than 230,000 participants. To take advantage of this benefit, be sure to enable heart rate tracking throughout the day.

To comply with the storage limit, up to 20 membership cards can be added to a single account. The supported codes are Code 128, Code 39, and QR codes.

For the complete list of 15 supported countries/regions and 14 languages, along with instructions on how to activate and use Alexa on your Amazfit GTS 4 device, please visit support.amazfit.com.

This feature is exclusively compatible with Android devices running version 6.10.0 or newer of the Zepp app.

The battery life may vary based on settings, operating conditions, and other factors. Therefore, actual results may differ from laboratory data. In a typical usage scenario: heart rate is monitored every 10 minutes, sleep tracking is activated, a static watch face is selected, the default screen brightness is used, 15 minutes of Bluetooth calls weekly, 30 minutes of music playback, 150 compact messages daily, 3 call notifications daily, wrist raise to check the time 100 times a day, blood oxygen level tested 5 times a day, bright screen on for 5 minutes daily, and GPS activated for 90 minutes weekly.

In battery saver mode, only specific features are available, such as manual heart rate measurement, blood oxygen levels, stress measurement, sports modes, personal activity index (PAI), daily activity, alarm, calendar, task list, and settings. Health monitoring functions like heart rate, blood oxygen level, and stress monitoring are disabled. Basic sleep monitoring is activated, Bluetooth is set to BLE, wrist raise screen lighting is turned off, and GPS is disabled.

Clock mode: Heart rate is monitored throughout the day, Bluetooth connection to the phone, and additional features are disabled; it only records step count and basic sleep data.

Intensive use case: continuous heart rate monitoring every minute, sleep tracking activated along with advanced sleep monitoring for 8 hours, stress tracking enabled; selection of a dynamic watch interface; weekly Bluetooth calls lasting 60 minutes, and 60 minutes of music playback; voice assistant activated; 150 daily notifications lighting up the screen; 3 call alerts each day; checking the time by raising the wrist 100 times a day; testing blood oxygen levels 5 times daily; bright screen activity for 15 minutes each day; GPS usage for running for 90 minutes a week.

Activating GPS mode: Enable dual-frequency GPS movement and heart rate monitoring with all satellites.

Enable balanced GPS mode to activate heart rate monitoring and location tracking using a single frequency (GPS + Beidou).

Activate the power-saving mode for the GPS system to enable heart rate monitoring and GPS tracking while reducing energy consumption (single frequency, low power consumption for the GPS).

The availability of models depends on your location.
