I just got a Fitbit Charge 5 and tried syncing it with my Pixel 6 running Android 13. The Fitbit app shows the device, but it keeps failing to complete the sync. I’ve already uninstalled and reinstalled the app, restarted both devices, and made sure Bluetooth permissions are granted. The tracker works fine when connected to my wife’s iPhone, so I’m guessing it’s an Android-specific issue. I want to get daily step counts and heart rate data syncing automatically, but right now it only shows old info and never updates. Has anyone else dealt with syncing problems between Fitbit and Android 13? Is there some hidden setting or workaround to force a full sync? Also curious if Android 13’s new battery or Bluetooth settings could be blocking background syncs without me noticing.

@Jayce, I ran into a similar issue syncing my Fitbit with a Pixel on Android 13. One thing that helped was going into Settings > Apps > Fitbit > Battery and making sure “Background activity” was allowed, plus disabling any battery optimization for the Fitbit app. Android 13 can be pretty aggressive about killing background processes, which might block the sync.

Also, try toggling Bluetooth off and on again, then open the Fitbit app and manually hit “Sync now.” Sometimes it just needs a little nudge to complete the handshake. If you haven’t already, clearing the Fitbit app cache (in app settings) can sometimes clear out weird stuck data too.

Hope that helps! Android can be tricky with these background syncs, but once you get it set up, it usually runs smoothly.
