Battery & Power

Battery life up to 7 days, or up to 5 hours with continuous GPS use. Battery life and charge cycles vary with use, settings, and other factors; actual results will vary. We recommend charging every few days to ensure you’re always tracking.

• Battery type: Lithium-polymer
• Charge time (0-100%): Two hours
• Radio transceiver: Bluetooth 4.0
• Memory
• Saves 7 days of detailed motion and heart rate data, minute by minute
• Saves daily totals for past 30 days

Measures 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 Charge 4™ in a hot tub or sauna. Learn more.

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. Learn more.

Materials

This tracker includes a plastic resin case and the band includes a stainless steel buckle. The classic band is made of a flexible, durable material similar to that used in many sports watches. The woven band is made from a comfortable polyester.
