Saves daily totals for the last 30 days
Stores 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 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.
Charge 6 is designed to comply with a water protection rating of 5 ATM under ISO standard 22810:2010 when manufactured, but it is not waterproof. Water resistance is not a permanent condition and decreases or is lost over time due to normal wear and tear, repair, disassembly or damage. Dropping your Charge 6 may result in loss of water resistance. Charge 6 is designed to be used in shallow water and should not be used for activities involving water at high velocity or high temperature. Some Charge 6 bands are not water resistant. See here for details.

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

Environmental Requirements
Operating temperature: 14° to 113°F
Maximum operating altitude: 28,000ft

Compatibility
Google account will be required. See here for compatible devices. 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:
Syncing range: Up to 30ft.
Certain features like smartphone notifications may require Android 9+. Check your device compatibility.
Syncing requires Bluetooth® LE, an internet connection and location permissions granted on the phone.

Materials
The Charge 6 housing is made of aluminum, glass and resin. The band is made of silicone and has an aluminum buckle.

Battery & Power
Battery life of up to 7 days. Use of the always-on display and SpO2 features will require more frequent charging. We recommend charging your tracker every few days to ensure you are always tracking.
Average battery life is approximate and is based on testing conducted in California in mid 2023 on pre-production hardware and software, using default settings with a median Fitbit user battery usage profile across a mix of talk, data, standby, and use of other features. Battery life depends on features enabled, usage, environment and many other factors. Use of certain features will decrease battery life. Actual battery life may be lower.
