Fitbit Charge 6 Tracker

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.

• Battery type: Lithium-polymer
• Charge time (0-100%): Two hours
• Radio transceiver: Bluetooth

• Optical heart rate monitor
• 3-axis accelerometer
• Built-in GPS + GLONASS
• Red and infrared sensors for oxygen saturation (SpO2) monitoring. Not available in all countries. Not intended to diagnose or treat any medical condition or for any other medical purpose. Intended to help you manage your well-being and keep track of your information. Requires more frequent charging.
• Device temperature sensor (skin temperature variation available in the Fitbit app). Only available in the Fitbit app and only displays variation. Not available in all markets. Not intended for medical purposes. Significant changes in ambient temperature may negatively impact skin temperature tracking.
• Vibration motor
• Ambient light sensor
• NFC
• Multipurpose electrical sensors compatible with ECG app & EDA Scan app

• AMOLED display
• Corning® Gorilla® Glass 3

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.

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.
