The Amazfit GTR 4 adheres to the ISO 22810-2010 standard, featuring a water resistance rating of 5 ATM, which translates to 50 meters. It is ideal for exposure to splashes, snow, showers, and swimming, having undergone testing by SGS (report number: SWT2206-12). To maintain its water resistance, avoid wearing it during hot showers or sauna sessions, as excessive steam may compromise the seal. When swimming, opt for a fluoroelastomer strap or another appropriate type instead of leather or metal. For further details, please visit the support page: support.amazfit.com.

Live Sports Data Broadcast offers voice broadcasts in both English and Chinese.

The music storage capacity reaches up to 2.3GB; with songs averaging between 5-10MB, it can hold around 270-470 MP3 tracks, considering the usage of system space.

The precision and responsiveness of the workout recognition feature hinge on the user's posture and proficiency during exercise. Brief workout sessions or frequent shifts in positioning may prevent the feature from activating. Activities like driving or riding a bus could inadvertently trigger recognition if they mimic the chosen workout mode. Insufficient GPS signals or unsynchronized AGPS data may lead to outdoor activities being inaccurately identified as indoor ones.

Smart recognition for strength training exercises is exclusive to the Strength Training sports mode and supports 25 exercises, including Bodyweight squats, Barbell squats, Tricep pushdowns, Bent over rows, and more. If an exercise isn't automatically recognized, the Zepp App offers a selection of muscle groups or exercise names for you to choose from.

Indoor positioning services may be limited. The speed and accuracy of positioning can be influenced by the surrounding environment. The number and type of connected satellites can vary based on your location.

The straight path back to the origin serves as a guide, though it may not always be feasible due to environmental factors. This feature is designed to help you maintain your position in relation to the starting point during your journey. The navigation functions cater to these 18 sports modes: Outdoor running, Walking, Outdoor cycling, Climbing, Hiking, Cross-country skiing, Mountain biking, BMX, Outdoor boating, Bobsleigh and tobogganing, Sledding, Ski orienteering, Biathlon, Race walking, Snowshoeing, Trail running, Orienteering, and Open water swimming.

Run mode and Smart Trajectory Correction are only compatible with running tracks that measure 200 meters or 400 meters in length.

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

The Always-on Display showcases system content while the screen is lit and displays the time during standby. To enable this feature, users must manually configure it. They can toggle it on or off using either the watch or the Zepp App.

Battery life may vary based on settings, operating conditions, and other factors, potentially leading to discrepancies from laboratory data. Various usage scenarios can influence battery drain, such as standard use with specific activities enabled, Battery Saver Mode which limits functions for efficiency, Clock Mode for basic tracking, and Heavy Usage Scenario that enhances features for demanding applications. Different GPS modes, including Accuracy GPS Mode, Balanced GPS Mode, and Power Saving GPS Mode, offer differing levels of performance and energy consumption.

To enrich the Zepp App experience for users, please enable 24-hour monitoring of heart rate and blood oxygen saturation (SpO2). Activate the Auto Heart Rate Monitor with a minimum interval of 1 minute for effective tracking. Set up alerts for abnormal heart rates and establish the SpO2 threshold in the app settings. Wear the watch snugly, approximately one finger-width from the wrist, to ensure precise SpO2 readings, and keep your arm steady. Configure SpO2 alerts for levels dropping below the preset value (minimum 80%). Be aware that external factors may influence monitoring accuracy. Activate 24-hour stress level monitoring in the app or on the watch, set alerts based on the stress threshold, and enable prompts for breathing exercises.

This product and the Zepp App are not medical devices and should not be used for medical purposes or as a basis for diagnosing any health condition. The detection results are provided for reference only. If you experience any discomfort, please consult professional medical institutions.

To obtain accurate results with the one-tap measurement and manual metric readings, wear the watch snugly, about one finger's width from your wrist, and keep your arm still. Movement, environmental factors, and personal physical characteristics can affect the precision of monitoring and measurements.

The sleep monitoring feature of the Zepp App can record nightly rest and naps longer than 20 minutes. To enable Sleep Breathing Quality tracking, adjust the settings either in the app or directly on the watch.

Morning updates can be configured via the Zepp App or through the watch settings. The available content encompasses weather, battery status, sleep data, schedule, PAI score, menstrual cycle tracking, and activities from the previous day.

The HUNT Fitness Study showed that individuals with a PAI score of 100 or more have a lower risk of hypertension, heart disease, and type-2 diabetes. This comprehensive research, led by Professor Ulrik Wisloff from the Faculty of Medicine at the Norwegian University of Science and Technology, lasted over 35 years and included more than 230,000 participants. Ongoing heart rate monitoring throughout the day is crucial to benefit from this feature.

The account can accommodate a maximum of 20 membership cards due to storage constraints. It supports codes such as Code 128, Code 39, and QR codes.
