We could not fully consult the manufacturer's support page for this model; the steps are general and may differ in details.
Most likely causes
Phone Bluetooth is off or malfunctioning
- Turn Bluetooth off and on again on your phone.
- Toggle airplane mode on then off to reset wireless radios.
- Restart your phone if Bluetooth still fails.
Charge 6 is asleep or low on battery
- Make sure the watch is awake by tapping the screen.
- Place the Charge 6 on the charger until the charging icon appears.
- Try pairing again while the watch is on the charger.
Watch is still linked to another account or device
- Sign out on other phones that previously paired with this Fitbit account.
- Remove the Charge 6 from Bluetooth settings on other phones if still paired.
- Retry the pairing process in the Fitbit app on your phone.
App glitch or temporary software issue
- Close the Fitbit app completely and reopen it.
- If that fails, reinstall the Fitbit app.
Factory reset
Warning: a factory reset will erase all personal data and settings on the Charge 6 and prepares the watch for pairing with another account.
- Turn on the Charge 6 and go to the watch's main menu.
- Find 'Settings' on the watch and open it (if not visible, look for 'About' or similar).
- Select 'Factory Reset', 'Clear User Data' or 'Reset' and confirm that you want to erase the device.
- Wait for the watch to complete the reset and restart.
- After reset: open the Fitbit app and add the Charge 6 again via 'Set up a device'.
