Battery life of up to 7 days. Use of the always-on display and SpO2 features will require more frequent charging. We recommend charging your tracker every few days to ensure you are always tracking.

Water resistant up to 50 meters. After getting the band wet, we recommend drying the band because, as with any wearable device, it's best for your skin if the band is clean and dry.
