How to charge the device and battery information
How do I charge the device?
- Remove the device from the wrist strap. Connect the device with the USB adapter via a USB cable, and plug it into a power outlet (ensure that the USB connector is correctly oriented). To reduce the charging time, the device's screen switches off while charging. However, you can swipe the screen to wake it and check charging progress.
- Typically it takes 1-2 hours to fully charge the device. The battery life is approximately 10 days for normal use and up to 21 days of standby time.
- Choose a power source to charge the device: either via a USB port of a PC or a charger of a mobile phone (the rated voltage of the device is 3.7V~4.2V, while the rated voltage of a USB port is usually 5V, so a USB port is an ideal choice). It usually takes 1-2 hours to fully charge the device via a USB port. Do not use a fast charging power source (9V), otherwise it may shorten the device's battery life.
Note: Enabling automatic heart rate monitoring and vibration alerts significantly reduces battery life.
Why is there a green light on the back of the device?
The green light is used to measure your heart rate. If you have enabled automatic heart rate monitoring, the light will turn on periodically. To disable this feature, select Manual Heart Rate Monitoring. Your device features an industry-standard optical heart-rate sensor that is certified as safe to use.
