workout.
9. GPS
The watch will automatically initiate the search for a GPS signal when you select an outdoor
activity from the sports widget and alert you when the positioning is successful. GPS is
automatically turned off when you leave sports widget or complete an activity.
It will search GPS signal continuously for 3 minutes. If it fails to positioning, it will ask you
to re-search. After 20 minutes of inactivity, the watch will stop searching to conserve the
battery. If you continue to use it, you need to re-search.
⚫Tips for Positioning:
GPS Positioning should be done in an open area in the outdoor. We recommend searching
GPS before starting an activity and waiting until GPS has full signal. The longer you wait the
more it will grab and the better your signal will be. If you are in a crowd, raising your arm to
your chest speeds the positioning.
⚫AGPS
Assisted GPS (A-GPS) is a system allowing global positioning system (GPS) receivers to
obtain information from network resources to assist in satellite location. An A-GPS system is
especially useful when the receiver is in a location where it is difficult for the satellite signals
to penetrate.
AGPS will help your watch find your precise position quickly and improve accuracy. The
A-GPS data updates once a day. The latest A-GPS data is automatically updated each time
you sync it with Amazfit Watch App. If watch hasn’t sync with your Amazfit Watch App for 7
days, AGPS data will expire. The positioning speed may be affected when AGPS expires and
watch will remind you to update when you start an activity.

Stroke Count: Stroke Count is the number of strokes you take to cover a length of the pool.
Stroke Rate: Stroke rate is how many strokes you take per minute (counting both arms).

Metrics
Amazfit Stratos provides a wealth of physical activity metrics such as VO2 max, training
effect, training load and more.
The score is a great help for your training or exercising. This assessment allows you to see
changes in your performance level as they happen and can help identify affecting factors
along the way. These metrics are based on your personal background information (age, gender,
height, weight, etc.) and heart rate. As your Stratos continually understands and analyzes your
body and activity data, the assessment of your score will be more accurate.
1）VO2max
VO2 max, or maximal oxygen uptake, is a common measurement linked to aerobic
endurance that many athletes use to determine their overall fitness. VO2 max is the
measurement of the maximum volume of oxygen that you can consume during intense, or
maximal exercise. It is measured as milliliters of oxygen used in one minute per kilogram of
body weight (ml/kg/min). It is one factor that may help determine an athlete's capacity to
perform sustained exercise. A high VO2 max is necessary for success in endurance events.
The calculation relies on a combination of personal background information (age, gender,
height, weight, etc.) and data collected during your activity. This includes a focus on heart rate
and running/walking speed. VO2 max varies greatly between individuals.
How to get my VO2 Max?
1) Enter your accurate personal data (age, gender, weight, height) in Amazfit Watch App.
2) Wear your Stratos and run for at least 10 minutes outdoor. Save your run and your heart
rate result should reach 75% of the maximum heart rate you set.
3) View your VOX max in the activity history from your watch or tap “my status” in
