CONSUMER NOTICE
Fitbit determined that a limited number of Fitbit Sense and Fitbit Versa 3 devices (“Impacted Devices”) are at risk of their batteries overheating, which poses a potential risk for users and requires an immediate firmware update. The firmware update will reduce the risk of the battery overheating and reduce battery capacity. The update will begin to roll out to impacted Sense and Versa 3 devices over the next month, starting on January 21, 2025. This issue does not affect all Sense and Versa 3 devices; if your device is not impacted, the battery will perform the same as before.
Background
Fitbit devices, like other wearable devices on the market, use rechargeable lithium-ion batteries—and these batteries are consumable components that may experience performance, capacity, or runtime degradation as they are used.
Changes coming to your device's battery management
Impacted Sense and Versa 3 devices will receive a firmware update over the next month, starting in January 2025. If you regularly sync your Sense or Versa 3 device with the Google Health app and your device is impacted, you’ll see a notification on your watch and in the Google Health app, as well as receive an email from us, when the firmware is available for you to install. The update will improve the stability of the device’s battery performance and reduce the risk of the battery overheating. As a result, the battery will last for shorter periods between charges and you may need to charge your device more frequently.
After the update is available, you must manually update your device’s firmware. A few days after receiving the update, if you don’t update your firmware, your device will experience a factory reset. Before your device experiences a factory reset, first your data will sync to your account and then the reset happens. While your most recent data will sync to your account, some information will be deleted, including your alarms, goals, credit and debit cards, saved settings, and notifications. After a factory reset, you must set up your device again. During that setup process, the new firmware will install on your device. If you don’t immediately set up your device again, your device won’t begin recording data until you do so. The firmware update does not impact any other Fitbit devices.

While the risk of overheating is low, you may choose to not use your Impacted Device until the firmware update is available for you. After you complete the update, you can continue to use your device as normal. Update your device’s firmware as soon as possible after receiving the update, which will begin to roll out starting January 21, 2025. After a few days, if you don’t install the update, your device will perform a factory reset which will install the new firmware. A factory reset deletes any data stored on the device, which includes all data that hasn't synced to your Fitbit account and your alarms, goals, credit and debit cards, saved settings, and notifications. After a factory reset, you must set up your device again. During that setup process, the new firmware will install on your device.
Follow local transportation guidance as usual. In general, rechargeable lithium-ion batteries are allowed in carry-on baggage but are prohibited from checked luggage. Please see the FAA’s PackSafe for Passengers webpage for more information.
