1. 1,000nit brightness is not supported by the Low Temperature mode or if battery life is below 30%. Depending on your environment, the watch can reach up to 1,000nit brightness after automatic brightness has been enabled in the watch settings.
2. The relevant data on this topic comes from the following report: H202109248524-01EN. Prolonged exposure is not recommended as it may damage the watch and its components.
3. The low temperature mode is turned off by default and needs to be enabled in the watch settings. After being enabled, whenever the temperature of the watch surface is lower than -10°C, the watch automatically enters low temperature mode, and only limited functions can be engaged at this time. Due to the physical characteristics of lithium batteries, the endurance of watches in low temperature environments will be affected to a certain extent. The battery life while in ultra-low temperature environments may vary according to the settings, operation conditions and other factors, so the actual result may differ from the laboratory data.
Ultra-low temperature operation with GPS on (-10℃ to -30℃): Wear the watch all day with low temperature mode and GPS enabled; raise wrist to see watch time 100 times; 150 pushed messages a day; bright screen operation for 5 minutes per day.
Ultra-low temperature operation with GPS off (-10℃ to -30℃): Wear the watch all day with low temperature mode enabled and GPS disabled; raise wrist to see watch time 100 times; 150 pushed messages a day; bright screen operation for 5 minutes per day.
4. 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.
5. The Amazfit T-Rex Ultra can be used as a map browsing tool to import OSM map files. Display of offline maps is only compatible with sports modes which support GPS positioning. The downloaded offline map must match your real location to be displayed, and a route file must be imported for navigation – it's not possible to choose a point on the offline map for navigation.
6. The shown straight line back to the start of a journey may not be a practical route to follow due to environmental factors; this is only intended to help you keep track of your position in relation to the start point of the journey. Navigation functions are compatible with 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, Open water swimming.
7. 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.
8. This feature needs to be enabled in the watch settings or Zepp App.
9. Corresponding sports modes include: Outdoor Running, Treadmill, Walking, Indoor Walking, Outdoor Cycling, Pool Swimming, Rowing Machine, Elliptical. 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.
10. Suitability for, and resistance to, diving is according to the EN13319 standard (report number is: S20221228846301) and the ISO 6245 standard (report number is: SHER230100000471).
11. According to the ISO 22810:2010 standard, the Amazfit T-Rex Ultra achieves a rating of 10 ATM, for a water-resistance of up to 100 meters, and is therefore suitable for splashes, snow, showering, swimming, and some high-speed water sports. It has passed third-party testing conducted by SWQC (SGS certification), and the report number is SWT2301-17. 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
12. Smart recognition of strength training exercises can only be engaged within the Strength Training sports mode. 25 exercises are able to be recognized at time of product release, including: Bodyweight squats, Bodyweight straight arm front squats, Barbell squats, Tricep pushdowns, Bent over rows, Barbell bench press, Sit-up holds, Knee-touch sit-ups, Dumbbell flys, Burpees, Burpee jumps, Overhead tricep extensions, Lying tricep extensions, Lateral raises, Jumping jacks, Lat pulldowns, Deadlift, Push-up, Shoulder press, Pull up, Bicep curls, Seated cable rows, Dumbbell drag curls, Straight-arm pulldowns, Russian twists.

13. Training templates and interval training templates are compatible with: Outdoor running, Treadmill, Outdoor cycling, Indoor cycling, Rope skipping, Rowing machine, Indoor fitness, Core training, Strength training and Stair climbing.
14. Only cycling power meters that support BLE connection are compatible with the watch.
15. The maximum storage space for music is 2.3GB (due to the system space occupied, the actual space used by the user may be less than 2.3GB); based on 5-10MB per song, it can store up to 270-470 MP3 songs. The watch has no built-in speaker, so connect via Bluetooth to your TWS earbuds to listen to music.
16. Live Sports Data Broadcast supports English and Chinese voice broadcasts.
17. Real-time performance scores and VO2 Max are only supported within Outdoor Running and Track Run modes.
18. adidas Running requires Zepp App version 7.1.0 or higher. Strava, Relive, and adidas Running availability may vary depending on your country or region. Apple Health is only available on iOS devices, and Google Fit is only available on Android devices.
19. The battery life may vary according to the settings, operation conditions and other factors. So the actual result may differ from the laboratory data.

1. 1,000nit brightness is not supported by the Low Temperature mode or if battery life is below 30%. Depending on your environment, the watch can reach up to 1,000nit brightness after automatic brightness has been enabled in the watch settings.
2. The low temperature mode is turned off by default and needs to be enabled in the watch settings. After being enabled, whenever the temperature of the watch surface is lower than -10°C, the watch automatically enters low temperature mode, and only limited functions can be engaged at this time. Due to the physical characteristics of lithium batteries, the endurance of watches in low temperature environments will be affected to a certain extent. The battery life while in ultra-low temperature environments may vary according to the settings, operation conditions and other factors, so the actual result may differ from the laboratory data.
3. The relevant data on this topic comes from the following report: H202109248524-01EN. Prolonged exposure is not recommended as it may damage the watch and its components.
Ultra-low temperature operation with GPS on (-10℃ to -30℃): Wear the watch all day with low temperature mode and GPS enabled; raise wrist to see watch time 100 times; 150 pushed messages a day; bright screen operation for 5 minutes per day.
Ultra-low temperature operation with GPS off (-10℃ to -30℃): Wear the watch all day with low temperature mode enabled and GPS disabled; raise wrist to see watch time 100 times; 150 pushed messages a day; bright screen operation for 5 minutes per day.
4. 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.
5. The Amazfit T-Rex Ultra can be used as a map browsing tool to import OSM map files. Display of offline maps is only compatible with sports modes which support GPS positioning. The downloaded offline map must match your real location to be displayed, and a route file must be imported for navigation – it's not possible to choose a point on the offline map for navigation.
6. The shown straight line back to the start of a journey may not be a practical route to follow due to environmental factors; this is only intended to help you keep track of your position in relation to the start point of the journey. Navigation functions are compatible with 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, Open water swimming.
7. 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.
8. This feature needs to be enabled in the watch settings or Zepp App.
9. Corresponding sports modes include: Outdoor Running, Treadmill, Walking, Indoor Walking, Outdoor Cycling, Pool Swimming, Rowing Machine, Elliptical. 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.
