Battery and Power
Fitbit Charge 3 has a battery life of up to 7 days. Battery life and charge cycles vary with use, settings and other factors; actual results will vary. We recommend charging your tracker every few days to ensure that you are always tracking.
- Battery type: Lithium-polymer
- Charge time (0-100%): Two hours

Fitbit Charge 3 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 Charge 3 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 Charge 3 classic band is made of a flexible, durable material similar to that used in many sports watches, and includes an aluminium buckle. The woven band is made from a comfortable polyester and includes an aluminium buckle.
Like all heart rate tracking technologies, accuracy is affected by physiology, location of device and different movements.
