Bluetooth Disabled/Damaged On Smartphone
Before connecting your smartwatch to your smartphone double check that Bluetooth setting is "ON". Go to phone settings, Bluetooth menu, enable/scan for devices. Select Blaze from available devices to connect.

Your tracker may be using outdated firmware, perform a system update to get the latest issue-free system version from Fitbit.

Make sure your device is fully charged to prevent issues during installation. Tap or click Select Account. Then tap or click the Update Tracker button. This option will only be available if Fitbit has released a new update. Follow the on-screen prompts and keep your tracker close to your smartphone during the update to prevent disconnection.

If a system restart did not fix the unresponsive screen, the screen may need to be replaced.
Poor Battery Life
Device will not charge properly or battery is suddenly draining quickly.
Check the contacts on the tracker where the charger plugs in. Over time, dirt can collect on the contacts and prevent a proper charge. Use a cotton swab soaked in rubbing alcohol to lightly dab the contacts clean.
Note: The clean contacts should appear gold in color.
Using a different USB port
Try plugging your charger into a different USB port, or a new outlet altogether. One of those may be defective and is preventing your device from charging.
Disabling some unused features on your device will help conserve battery life. These settings can be switched on and off in the settings menu on your device.
- Heart Rate data collection
- Lower brightness
- All-Day sync
- Quick View
If these methods do not improve your battery life, your battery may need to be replaced. Please follow our replacement guide here Battery Replacement
Heart Beat Monitor Not Working
There are two different ways your heart beat monitor will fail. The first way is that the heart beat monitor stops giving a reading and the second is that the lights in the back of the smartwatch stop working.
Heart Beat Monitor Stopped Giving a Reading
If the heart beat monitor is not tracking your heart beats, Go to the settings option and go to Heart Rate Tracking. Turn the setting on to AUTO, Make sure the band is tight around wrist. If it is not tight enough the heart rate monitor can not read your heart rate. Try moving the band around your hand with higher or lower variations in the arm. If it is still not working try switching the setting to ON. This will enable the green light on the back of the tracker even when you're not wearing it. Note: If it is still not working, restart your tracker using our How Do I Restart My Tracker above.
Green Lights Not Working
If the lights are not working, check your profile settings to make sure if heart rate setting is set to auto or on.
Faulty Heart Rate Monitor
If none of the above fixes the issue then you have a faulty heart rate monitor. Contact Fitbit customer support in order to request a replacement.
