³ Maximum battery life is approximate and is based on testing conducted in 2025 on pre-production hardware and software, using default settings with a median Google Fitbit Air user battery usage profile across 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. Over time, Fitbit software will manage battery performance to help maintain battery health as your battery ages. See g.co/fitbit/battery for more information on battery life.

⁴ Like all heart rate tracking technologies, accuracy is affected by physiology, location of the device, and your movements and activity. Some uses may require the mobile app.

⁵ Not available in all countries. The SpO2 feature is not intended to diagnose or treat any medical condition or for any other medical purpose. It is intended to help you manage your well-being and keep track of your information. This feature requires more frequent charging.

⁶ Not available in all markets. Significant changes in ambient temperature may negatively impact skin temperature tracking.

⁷ Google Fitbit Air 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 Google Fitbit Air may result in loss of water resistance. Google Fitbit Air is designed to be used in shallow water and should not be used for activities involving water at high velocity or high temperature. See g.co/fitbit/waterproof for details. After any exposure to liquid, we recommend drying the Google Fitbit Air because, as with any wearable device, it’s best for your skin if the band is clean and dry.

⁸ While this product is designed to be water-resistant, this resistance is achieved through a specialised surface coating/treatment. This protection is not permanent. The protective water-resistant coating may diminish or be completely removed over time due to normal wear and tear, environmental exposure, and regular use. Google does not guarantee continued water resistance for the lifespan of the product and excludes liability for any damage resulting from moisture exposure following the natural degradation of the coating.

⁹ Charging speed based on use of in-box USB-C® at 22 to 30 degrees C. Actual results may be slower Based on testing, charging speed with fully drained device batteries. Charging testing conducted in 2025 on pre-production hardware and software using default settings with the device powered on. Charging speed depends upon many factors including battery age and ambient temperature.
