Fitbit Charge 5 will not pair with the phone

Fitbit Charge 5 will not pair with the phone: compatibility, Bluetooth state, app/account, prior phone and reset consequences should be separated. Scoped to FB421.

A Fitbit Charge 5 that will not pair with a phone, will not sync or has disappeared from the Fitbit app has a Bluetooth or an account problem, and the Charge 5's touch-only design means a few steps are different from older trackers. This is Fitbit's advanced fitness band with built-in GPS, ECG and stress sensing, continuous heart rate and a touchscreen with no physical button. It shows phone notifications but has no speaker or microphone. It pairs with a phone through the Fitbit app over Bluetooth and keeps its data synced.

The checks in more detail

Start with the phone. Check that Bluetooth is on, that the Fitbit app is open and up to date, and that the app has permission for Bluetooth, nearby devices and, on Android, location, since Android needs it for scanning. Make sure the phone is running a supported operating system version. Turn Bluetooth off and on and keep the phone close to the tracker. In the Fitbit app, tap Today, your profile picture and choose Set up a device, and follow the steps.

If the Charge 5 is already listed in the app but does not connect, open Bluetooth settings on the phone, find any entry named Charge 5, and forget it, then try again, since a stale entry blocks pairing. Then the tracker. Charge it, since a flat battery will not pair; plug it into its charger for a while. Restart the Charge 5 using the method in Fitbit's guide for this model, which uses the button on the charging cable pressed in a set pattern, not a button on the tracker. A restart does not delete data.

If the tracker is still not found, remove it from your account in the app, then add it again. Make sure that you are signed in to the same Google or Fitbit account. Close other apps that use the tracker's Bluetooth, and avoid pairing it with a second phone. Update the Fitbit app and the phone's software. If pairing fails on every phone, factory reset the tracker, which erases the data on the tracker that has not been synced, and set it up again. Contact Fitbit support with the serial number if the tracker still will not pair.
