GPS and AGPS
When you go to the Workout Preparation screen during outdoor workout such as
outdoor running, the watch automatically starts GPS positioning and notifies you
immediately after positioning is successful. GPS positioning is automatically disabled
after you finish your workout.
Use GPS positioning in an open outdoor space, and wait until positioning is successful
before you begin your workout. If you are in a crowd, raise your arm to your chest to
accelerate positioning.
AGPS provides GPS satellite orbit data to help the watch accelerate GPS positioning.
Keep the watch connected to the phone's Bluetooth. Each time you connect the watch
to the Zepp app, the system automatically checks for and completes updates. The
watch periodically synchronizes data from the Zepp app. Otherwise, AGPS data
expires, which affects the speed and accuracy of positioning. In this case, the watch
prompts you to connect to the Zepp app to update AGPS for accelerated positioning
when you begin a workout.
Heart rate range for workout
When you are working out, the watch calculates your heart rate range based on your
personal information. You can determine the effect and intensity of workout based on
the heart rate range. On the watch, you can view your current heart rate range in the
heart rate data column. After you finish the workout, you can open the Zepp app and
find the current workout records to view the workout duration in each heart rate range
on the Details screen.
By default, six heart rate ranges are provided.
The default heart rate ranges are calculated by estimating the maximum heart rate. The
watch calculates the maximum heart rate by the common formula of subtracting your
age from 220.
Heart Rate Range
How to Calculate
Relaxed
Less than 50% of the maximum heart rate
Warm-up
[50%, 60%) of the maximum heart rate
Fat Burning
[60%, 70%) of the maximum heart rate
Aerobic
[70%, 80%) of the maximum heart rate
Endurance Training
[80%, 90%) of the maximum heart rate
Anaerobic Maximum
More than 90% of the maximum heart rate
