How To Fix My Fitbit Surge Won’t Sync?

The solutions in this guide are designed to troubleshoot your Fitbit Surge in consecutive steps and solutions.

In that regard, make sure you follow our steps in the respective order for best results at troubleshooting.

Here’s how to fix the syncing of your Fitbit Surge, for all types of connected devices:

Solution #1 Charge Your Fitbit

You should first charge your Fitbit Surge watch all the way and check the syncing.

There are plenty of reported cases, where Fitbit is unable to sync whenever it has too low a battery to execute any sort of function.

In that regard, connect your Fitbit to the charger and wait for 30 up to 60 minutes.

It’s recommended to have the battery at full before testing the sync, but half the bars should be enough to determine if the syncing issue is fixed.

Note: Ensure that while your Fitbit is charging, it stays on all of the time, so it doesn’t disconnect from your phone or PC.

Solution #2 Reconnect Bluetooth

If charging your Fitbit didn’t fix the sync between your devices, you should attempt to reconnect the watch from your device’s Bluetooth.

Regardless of whether you’re using a computer or phone to connect with your Fitbit, reconnecting the Bluetooth has the best effect towards a refresh of the sync and fixing the issue.

Here’s how to reconnect Fitbit from your device’s Bluetooth:

1. On your device connected to Fitbit, go to Settings > Wireless.
2. In the wireless tab, choose Bluetooth and open the Connected Devices list.
3. Locate your Fitbit watch.
4. Tap on “Disconnect” to unpair the device from your Bluetooth.
5. Wait for 30-60 seconds, and re-discover your Fitbit by connecting it.

Note: Make sure that throughout this entire solution, your Fitbit watch is close to your device in order for the Bluetooth connection to work.

Solution #3 Reconnect Device To Internet

In order for your Fitbit to sync, your device must be connected to the internet.

Since both of the devices connect with Bluetooth in the first place, your connected device has to be either connected to the WiFi or have mobile data turned ON.

Based on whether you’re using a phone or computer for your Fitbit, go to Settings > Wireless > WiFi, find your own WiFi and enter the password to connect.

If you prefer mobile data (3G,4G,5G) over the WiFi, enable the feature from the settings, based on the type of your device.

Note: It might take a while for your Fitbit to start syncing once your device got reconnected to the internet. 

Make sure not to disconnect it from the Bluetooth during the time, before the syncing completes.

Solution #4 Reinstall Fitbit App & Reconnect Watch

If your phone is connected to the internet, but your Fitbit watch doesn’t seem to be syncing, you should attempt to reinstall the Fitbit application, to solve the problem.

Since the application creates the connection bond between your watch and phone, there could be a problem with the platform, thus, your watch doesn’t sync.

Here’s how to reinstall the Fitbit app from your phone and then reconnect it to the watch:

1. In your smartphone settings, go to the storage unit.
2. Locate the Fitbit app.
3. Select “Uninstall” and wait for the app to be deleted.
4. Go back to the app store and download the Fitbit app back onto your phone.
5. Once installed, open the application and select your type of watch from the screen.
6. Follow the rest of the on-screen instructions to pair your watch.

Pro Tip: Ensure that your phone has enough storage when downloading the Fitbit app in order for it to be stored safely without corrupting any data.

Solution #5 Erase Phone Bluetooth Settings

The next thing you should do is to re-add the Fitbit connection from your phone’s Bluetooth settings.

This will erase all configurations that have been made so far to your watch, hopefully fixing the syncing issue.

Here’s how to erase your phone’s Bluetooth settings:

1. Go to the settings tab of your smartphone.
2. Open Wireless and choose Network.
3. Tap on “Reset All Network Settings & Bluetooth”.
4. Confirm the process and wait.

Note: Once the erase of the network settings is done, the Bluetooth will also be reset.

You will have to pair your Fitbit Surge again after the process is complete.

Solution #6 Reset Fitbit Watch

If nothing worked so far, you should perform a factory reset on your Fitbit watch to fix the syncing.

The reset will erase all current system configurations you’ve made so far, along with bugs and glitches your device has developed over time.

Here’s how to reset your Fitbit watch:

1. On your Fitbit watch-tracker device, slide to open the Settings.
2. Go to the About tab and select Factory Reset.
3. Tap on Clear User Data.
4. Confirm the prompt that appeared on your screen.

Note: If your tracker was low on battery, make sure that it is connected to the power while the reset is ongoing.

Why Won’t My Fitbit Surge Sync With My Computer?

In case you’re not using a smartphone, instead, you’re trying to connect your Fitbit Surge watch to a computer, there are quite a few things that you should inspect.

Here is what could be preventing your Fitbit surge from syncing with your computer:

1. Bluetooth is not Turned On

Most computers do not have in-built Bluetooth. However, some laptops do have Bluetooth so make sure to determine that first.

In case your computer does not have in-built Bluetooth you can purchase a dongle for cheap.

2. Problematic Dongle

If you’re using a Bluetooth dongle to connect with your Fitbit, ensure the device is functioning properly.

3. Already Connected

Lastly, having your computer connected to a separate device rather than to your surge, both devices won’t be able to sync.

Tip: In case the issues seem to be coming from your Fitbit watch, check if your warranty is still in-tact and reach out to customer service.
