The Amazfit GTS 4 watch adheres to the ISO 22810-2010 standard, boasting a water resistance of 5 ATM, enabling it to endure depths of up to 50 meters. It is designed to withstand splashes, snow, showers, and swimming, having been tested by a third party, SGS, under report number SWT2206-14. It is recommended to avoid wearing the watch in hot baths or saunas, as excessive steam may compromise its water resistance. When swimming, it is advisable to opt for a strap made of fluoroelastomer rather than leather or metal. For further information, you can visit support.amazfit.com.

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

The music storage capacity reaches 2.3GB, allowing for approximately 270 to 470 songs in MP3 format, depending on each song's size of 5 to 10MB, while reserving some space for system functions.

The effectiveness of the exercise recognition feature varies based on personal differences in posture and skill level during workouts. Quick or diverse movements may not reliably engage the feature. Activities like driving or riding a bus could unintentionally activate recognition if they resemble the designated exercise. Furthermore, weak GPS signals or unsynchronized AGPS data during outdoor activities might be mistakenly identified as indoor activities.

Smart recognition of strength training exercises is solely offered in strength training mode. It accommodates 25 exercises, encompassing both bodyweight and weighted activities such as squats, presses, pulls, push-ups, and curls. If an exercise is not automatically identified by the watch, the Zepp app presents a selection of muscle groups or exercise names for you to choose from.

Indoor positioning services are unavailable. The speed and accuracy of location determination may be influenced by the surrounding environment. The number and type of satellites utilized may differ based on your location.

The direct routes returning to the journey's origin may not be feasible because of environmental factors; instead, they signify your position relative to the starting point. The navigation features accommodate 18 distinct 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 operating mode and smart track correction are compatible exclusively with running track lengths of 200 meters and 400 meters.

Interval training templates can be applied to: outdoor running, treadmill workouts, outdoor cycling, indoor cycling, jump rope sessions, rowing machine exercises, indoor fitness routines, strength training, core muscle conditioning, and stair climbing.

Always-On Display: The system content appears when the screen is illuminated, while the time is shown in standby mode. Users must manually enable the "Always-On Display" feature, which can be switched on or off using either the watch or the Zepp app.

To improve heart rate and blood oxygen monitoring in the Zepp app: - Turn on 24-hour heart rate and oxygen level tracking. - Set the heart rate monitor to track for a minimum of 1 minute. - Configure alerts for abnormal heart rates using predefined values. - Ensure accurate oxygen readings by wearing the watch snugly, about one finger's width from the wrist, and keeping your arm steady. - Set alerts for oxygen levels falling below the specified threshold (minimum 80%). - Take into account factors like movement and environment that may influence monitoring accuracy. - Activate 24-hour stress level monitoring on the watch or app. - Customize alerts for high-stress levels based on predefined values. - Enable notifications for breathing exercises on the watch.

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

To ensure precise outcomes when taking manual meter readings or with a single click, be sure to wear the watch comfortably, with it resting one finger's breadth from your wrist. Maintain a steady arm to improve monitoring accuracy, as both movement and surrounding factors can influence speed and precision.

Sleep tracking can monitor nighttime rest and naps exceeding 20 minutes. To track breathing quality during sleep, you can use the Zepp app or modify the settings within the watch's sleep feature.

Morning updates need to be set up in the Zepp app or the watch settings. The supported information includes weather conditions, battery status, sleep data, schedule, PAI score, menstrual cycle tracking, and yesterday's activities.

The HUNT study on fitness reveals that individuals with a PAI score of 100 or above have a reduced risk of developing high blood pressure, heart disease, and type 2 diabetes. This research, conducted by Professor Ulrik Wisløff from the Norwegian University of Science and Technology’s medical school, has spanned over 35 years and included more than 230,000 participants. To harness this advantage, ensure that heart rate tracking is activated throughout the day.

To adhere to the storage limit, a maximum of 20 membership cards may be added to one account. The accepted codes are Code 128, Code 39, and QR codes.

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

This feature is solely compatible with Android devices operating on version 6.10.0 or later of the Zepp app.

Battery life may fluctuate depending on settings, operating conditions, and various factors. Consequently, actual outcomes may vary from laboratory data. In a typical usage scenario: heart rate is monitored every 10 minutes, sleep tracking is enabled, a static watch face is chosen, the default screen brightness is applied, there are 15 minutes of Bluetooth calls weekly, 30 minutes of music playback, 150 brief messages daily, 3 call notifications daily, wrist raises to check the time 100 times a day, blood oxygen levels tested 5 times a day, the bright screen remains on for 5 minutes daily, and GPS is activated for 90 minutes weekly.

In battery saver mode, only certain features are accessible, including manual heart rate measurement, blood oxygen levels, stress assessment, sports modes, personal activity index (PAI), daily activity, alarm, calendar, task list, and settings. Health monitoring functions such as heart rate, blood oxygen level, and stress monitoring are turned off. Basic sleep tracking is enabled, Bluetooth is configured to BLE, wrist raise screen illumination is disabled, and GPS is turned off.

Clock mode: Heart rate is continuously monitored during the day, Bluetooth connectivity with the phone is active, and additional features are turned off; it solely tracks step count and basic sleep information.

Intensive use case: continuous heart rate monitoring every minute, sleep tracking activated with advanced 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 daily; testing blood oxygen levels 5 times a day; bright screen activity for 15 minutes each day; GPS usage for running for 90 minutes a week.

Activating GPS mode: Enable dual-frequency GPS tracking 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 facilitate heart rate monitoring and GPS tracking while minimizing energy usage (single frequency, low energy consumption for the GPS).

The availability of models is contingent upon your location.
