To confirm your Fitbit Sense is charging, wake the screen by double-tapping it or pressing the button while the device is on its charger; the battery level will appear for a few seconds and then disappear. This is the primary and most reliable way to know your Fitbit Sense charging process has started.
How to know your Fitbit Sense is charging
The clearest indicator that your Fitbit Sense is receiving power is the on-screen battery display. When you place the watch on its charging cable and wake the screen, the battery level icon appears briefly, typically for several seconds, before the screen turns off again. If you miss it, simply swipe right from the clock face while the watch remains on the charger; the battery level icon will be visible at the top of the screen. This method works whether the battery is mostly full or nearly empty, giving you immediate confirmation of charging status.
Check the battery level in the Fitbit app
If you prefer not to look at the watch itself, you can verify charging through the Fitbit smartphone app. Open the app and navigate to the Today tab, then tap the devices icon. The battery level for your Fitbit Sense appears to the right of your device name. This view updates in real time as the watch charges, making it a reliable secondary method to monitor progress.
What the low-battery icon means
When your Fitbit Sense’s battery is critically low, a special low-battery icon appears at the top of the clock face for three seconds each time you turn on the screen. This icon indicates the watch needs immediate charging and may not have enough power to complete a full sync or track activity. If you see this icon, place the device on its charger as soon as possible. For a fully depleted battery, one that reached 0%, you must leave the watch plugged into the charging cable for at least 30 minutes before it will power on or show any charging progress.
Troubleshooting Fitbit Sense charging issues
If your Fitbit Sense does not show the battery icon or appears to not be charging, follow these steps in order:
- Clean the charging contacts on the back of the device and the pins on the charging cable. Dirt, lint, or moisture can prevent a proper connection.
- Check the charging cable alignment and reconnect the device securely. Use only the cable that came with your Fitbit Sense, as most cables are not compatible with other devices.
- Try a different USB port or a UL-certified wall charger. The power source may not be delivering enough current.
- Restart the Fitbit Sense by pressing and holding the button for 10 seconds until the Fitbit logo appears. For a restart on Sense and Sense 2, press and hold the button for 10 seconds.
- If the battery was completely depleted to 0%, leave the device plugged in for at least 30 minutes before expecting it to turn on or show a charging indicator.
- Ensure the device is fully dry before charging if it has been exposed to water or sweat.
For deeper battery management, you can explore the Fitbit battery and power settings available in the app’s device settings menu. These controls help you understand usage patterns and extend charge life.
