Your Pulse HR can operate for up to 20 days on a single charge, depending on your use of the heart rate mode. Using the continuous heart rate mode all the time instead of just during activities will deplete the battery much faster.

Make sure that you have removed the sticker from the screen before charging the device.

To charge your Pulse HR, perform the following steps:

1. Connect the USB end of the charging cable to a power source.
   Note that the minimum current required for charging cable is 60mA.
2. Position the other end of the charging cable on the back of your Pulse HR in such a way that the magnets align.
   You can check the percentage of the battery on the display of the tracker while it’s charging.
   

Note that charging the Pulse HR using the USB port of a computer can result in a slower charge compared to a standard 5V 1A mobile device charger.
