About 15 days under the following conditions: (1)
Automatic heart rate detection with a 30-minute
frequency is enabled. (2) The band receives and
displays 100 notifications every day. (3) Two
alarms are set every day, and the band vibrates
for 5 seconds when each alarm is triggered. (4)
The touch button is pressed 10 times per day to
display the current time. (5) The app
synchronizes data once per day. In actual use,
the battery life is related to various factors such
as settings, operations, and use environments,
so it may be different from lab data.
