Top FAQs:
Battery, Charging, and Power Consumption
Why does my battery drain so quickly? How can I increase the battery life?
Which charging currents does the HUAWEI Band 3 Pro support?
The HUAWEI Band 3 Pro supports the following charging currents (with a 5 V charger): 0.5 A, 1 A, 1.5 A, and 2 A.
The power consumption of the band depends on what features are enabled.
The battery life is 12 days when the HUAWEI TruSleep and Continuous measurement of heart rate are disabled; seven days when the HUAWEI TruSleep
is enabled and Continuous measurement of heart rate is disabled; five days when the HUAWEI TruSleep and Continuous measurement of heart rate are
enabled; seven hours when you do exercises using your band's GPS.
The battery life also depends on your usage habits. The band will vibrate frequently when Bluetooth disconnection reminder and message reminder are enabled
and several alarms are set, which increases power consumption.
It is recommended that you disable some infrequently used features in the Huawei Health app to extend the battery life, such as:
HUAWEI TruSleep (Your band will still monitor your sleep duration.)
Continuous measurement of heart rate
Raise wrist to wake screen
Notifications management
Bluetooth disconnection reminder
If there is a low battery alert, please charge your band as soon as possible.
