The only official timing-related instruction for how long should it take to sync Fitbit is to sync manually from the Fitbit app and wait for the progress bar to fill completely.
Why syncing matters for your Fitbit
Syncing ensures the correct time displays on your Fitbit device. Fitbit says syncing is needed for the correct time to show on the device. Fitbit also says to sync after changing time zone settings so the correct time displays.
How to manually sync your Fitbit
On both iPhone and Android, open the Fitbit app and select the Today tab. Tap and hold on the screen, then pull down until a progress bar appears at the top. Release your finger and wait for the progress bar to fill. Keep your Fitbit device nearby during this process.
Fitbit sync troubleshooting for Android
If the manual sync does not complete, follow these official steps in order:
- Uninstall the Google Health app on any other phones or tablets nearby. Account conflicts from multiple devices can block sync.

Frequently Asked Questions
Why is my Fitbit sync taking a long time?
Fitbit does not publish a maximum sync time or data-size limit. If the progress bar does not fill after a reasonable wait, the issue is likely a connection problem or account conflict rather than normal sync speed. Follow the device- and platform-specific troubleshooting steps above.
Does my Fitbit sync automatically?
Fitbit devices are designed to sync automatically with compatible mobile devices when they are within range and connected via Bluetooth. However, automatic syncing may not occur if Bluetooth is disabled, the devices are out of range, or there is an account conflict from multiple devices.
Will syncing drain my Fitbit battery?
Syncing typically does not significantly impact battery life. If you notice a rapid battery drain, it is more likely due to features like continuous heart rate monitoring or GPS tracking rather than the sync process itself.
Can I sync my Fitbit without a phone?
Yes, Fitbit devices can be synced to a computer using the Fitbit Connect app. You need to download and install the app on your computer, connect your Fitbit device via the provided USB dongle or cable, and follow the app instructions to sync your data.
What if my Fitbit still won't sync after troubleshooting?
If you have completed all the documented steps for your platform and the sync still fails, contact Fitbit customer support for further assistance. The official help pages do not provide additional troubleshooting beyond the steps listed for Android and iOS.
