If your Fitbit keeps shutting off, the first step is to restart the device, which turns it off and on without losing activity data. If the problem continues, check that your phone is compatible with the Fitbit app and update the app to the latest version.
What to do when your Fitbit keeps shutting off
When a Fitbit keeps shutting off, the official fix path is straightforward: restart the device, verify phone compatibility, and update the Fitbit app. These steps are documented by Google as the primary troubleshooting approach for shutdown-type issues. No single universal cause is documented, so following this path in order gives you the best chance of resolving the problem. Possible causes include Low Battery, Overheating, Water Damage, Physical Damage, and Hardware Issues (faulty power buttons, battery connectors). As a prevention tip, strap the device securely to maintain skin contact and avoid extreme temperatures.
Step 1: Restart your Fitbit device
A restart is the first documented troubleshooting step for a Fitbit that keeps shutting off. Google states that a restart turns the device off and on without losing any activity data. This makes it safe to try immediately, as your recorded steps, sleep, and other metrics remain intact. The restart process varies by model, but the instruction is consistent: perform the restart as the initial action before moving to other steps.
Step 2: Make sure your phone is supported
If the restart does not stop the shutdowns, the next step is to confirm your phone meets the Fitbit app requirements. Google documents that the Fitbit app must run on an iPhone with iOS 15 or higher, or on an Android phone with Android 10 or higher. Using an unsupported phone or tablet can cause the Fitbit to behave unexpectedly, including shutting off. This check isolates whether the issue comes from the phone rather than the Fitbit itself. Also check for conflicting apps on your smartphone that might interfere with the Fitbit connection.
Step 3: Update the Fitbit app on your phone
An outdated Fitbit app can also cause shutdown problems. To update the app, open the Fitbit app on your phone, tap your profile picture, then tap your device image. From there, tap Manage apps & device, then tap Updates available and install any update shown. During the update process, keep the Fitbit close to the phone and on its charger. This ensures the update completes without interruption and the device remains connected.
Still shutting off? Contact Fitbit support
If you cannot restart the device, or if the Fitbit keeps shutting off after following all three steps, Google instructs you to contact Customer Support. The support pages do not provide a device-specific shutdown escalation path beyond this instruction, so reaching out directly is the next appropriate action. Have your device model and details ready when you contact them. As a last resort before contacting support, you can try a factory reset, but be aware this will erase all data and settings on the device.
