Fitbit Versa has a battery life of 4+ days. Battery life and charge cycles vary with use, settings, and other factors; actual results will vary. We recommend charging your watch every few days to ensure you are always tracking.

Saves seven 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

Fitbit Versa is water resistant to 50 metres. 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 Versa in a hot tub or sauna.

If the band gets wet or if you sweat in it, remove and completely dry it before putting it back on. Give your wrist a rest by taking the band off every now and then.

The Fitbit Versa classic band is made of a flexible, durable material similar to that used in many sports watches, and includes an aluminum watch case and buckle.

Like all heart rate tracking technologies, accuracy is affected by physiology, location of device and different movements.
