Battery and 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.

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.

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