Sensors & Components
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.
Memory
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.
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
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.
