A:Answer Hi there ,
- Typical usage scenario-18 days: Worn for consecutive 24-hour periods, heart-rate monitoring (data recorded every 10 minutes) is turned on, and SpO2 is measured twice a day. Every day, the screen turns on to display 150 messages and is operated for 5 minutes, and the user raises the wrist 30 times to check the time. The user exercises for 90 minutes every week.
- Heavy usage scenario-9 days: Worn for consecutive 24-hour periods, heart-rate monitoring and assisted sleep monitoring are turned on (data recorded every 1 minute), sleep breathing quality is enabled, and SpO2 is measured twice a day. Every day, the screen turns on to display 150 messages and is operated for 15 minutes, the user raises the wrist 100 times to check the time and exercises 180 minutes every week.
- GPS continuous working-40 hours: Turn on GPS recording motion track, turn on heart rate monitoring.
- The most power-consuming functions of the Amazfit T-Rex Pro watches include motor vibration and the light of the screen. If you often run for exercise, receive pushed messages frequently, or set a long screen-on duration, then it's normal that your watch runs out of battery power fast.
