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 and SpO2 features will require more frequent charging. We recommend charging every few days to ensure you’re always tracking.

Charge time: (10-80%): Approximately 40 minutes
Fast charging: 1 day of battery life in 12 minutes
Radio transceiver: Bluetooth®

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
Water-resistant to 50 metres. After 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.
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.
The Fitbit app is compatible with most popular phones. To set up and use your Fitbit products and services, you must install the Fitbit app on a compatible device running one of the following operating systems:
Apple iOS 12.2 or higher.
Android OS 8.0 or higher. See additional tips for Android phones here.
