Managing the clock on your Fitbit Charge HR is a straightforward process, but it requires understanding the specific steps for your device. As a dedicated fitness tracker, the Charge HR relies on syncing with your smartphone to update the time automatically. If you are experiencing discrepancies, the solution usually lies within your phone's app settings rather than the tracker itself.
Why Your Fitbit HR Time Might Be Incorrect
The most common reason your Fitbit Charge HR displays the wrong time is a disruption in the Bluetooth connection between the tracker and your phone. The device relies on the Fitbit app to pull the correct time from your phone's network. If the app has been force-closed, if your phone's location services are disabled, or if the Bluetooth connection is weak, the sync cannot occur.
Prerequisites Before Adjusting the Time
Before attempting to change the time, ensure your phone is ready to communicate with the tracker. You need to verify that the Fitbit app is running the latest version and that your phone has a strong internet connection. A stable Wi-Fi or cellular data connection is necessary for the app to fetch the correct time from the internet, which it then pushes to your Charge HR.

How To Change Time on Fitbit HR via the Mobile App
For most users, the correct time will update automatically once the tracker is synced. To initiate this sync and troubleshoot time issues, follow the steps below to force a sync through the Fitbit app.
Steps to Force a Sync
- Open the Fitbit app on your smartphone and ensure you are logged into your account.
- Tap the "Today" icon, usually located in the bottom navigation bar, to view your dashboard.
- Pull down slightly on the dashboard screen to trigger a manual sync. Wait for the spinning circle to indicate data is being transferred.
- Ensure Bluetooth is enabled on your phone and that the Fitbit Charge HR is connected within the app's device settings.
Manually Setting the Time on the Tracker
If the automatic sync does not resolve the issue, you may need to set the time directly on the device. This is particularly useful if the tracker's battery has been depleted for an extended period, causing it to lose memory of the clock.
Adjusting Time on the Charge HR
The Fitbit Charge HR does not feature a button interface for scrolling through settings. Instead, time adjustments are handled through the app interface. To change the time manually, you must actually change the time on your phone; the tracker will then reflect this change during the next sync.

Configuring Phone Settings for Accurate Time
Your phone acts as the brain for your Fitbit Charge HR. Therefore, the most reliable method to change the time is to adjust it on your smartphone. Once the phone updates its clock, you can force a sync to transfer the correct time to the tracker.
Recommended Process
- Go to your phone's Settings and navigate to "Date & Time."
- Ensure the option "Set automatically" is turned on. This allows your phone to sync with network time servers.
- If the time is incorrect, toggle "Set automatically" off, change the time, then toggle it back on to re-sync.
- Open the Fitbit app and perform a manual sync as described earlier.
Troubleshooting Persistent Time Issues
In rare cases, users may find that the time changes correctly on the phone but incorrect data persists on the Fitbit Charge HR display. If a manual sync fails to correct this, the issue is likely software-related. Updating the firmware of the tracker through the app usually resolves these glitches and restores accurate timekeeping functionality.
