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 feature 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
Memory
- Saves 7 days of detailed motion data – minute by minute
- Saves daily totals for past 30 days
- Stores heart rate data at 1-second intervals during exercise tracking and at 5-second intervals all other times
Water Resistance
Water resistant to 50 meters. After swimming or 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. We do not recommend wearing Fitbit Versa 3 in a hot tub or sauna.
Materials
Versa 3 includes a band made of a flexible material similar to that used in many sports watches, as well as an aluminum watch case
Heart Rate
Like all heart rate tracking technologies, accuracy is affected by physiology, location of device and different movements.
