Battery & Power
Battery life up to 6+ days. Battery life and charge cycles vary with use, settings, and other factors; actual results will vary. Use of the always-on display and SpO2 features will require more frequent charging. We recommend charging every few days to ensure you’re always tracking.
- Battery type: Lithium-polymer
- Charge time: (10-80%): Approximately 40 minutes
- Fast charging: 1 day of battery life in 12 minutes
- Radio transceiver: Bluetooth®
Memory
- Saves 7 days of detailed motion data, minute by minute
- Saves daily totals for the last 30 days
- Stores heart rate data at one-second intervals during exercise tracking and at five-second intervals all other times
Water Resistance
Water-resistant to 50 metres. 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.
Care
Give your wrist a rest by taking the band off every now and then. If the band gets wet or you sweat in it, remove and completely dry the band before putting it back on.
Materials
This watch includes a band made of a flexible material similar to that used in many sports watches, as well as an aluminum watch case and buckle.
