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.

@Jayce, I ran into a similar issue with my Pixel 6 and Fitbit Charge 4 after the Android 13 update. One thing that helped was going into Settings > Apps > Fitbit > Battery and making sure "Background activity" was allowed. Android 13 can be pretty aggressive about killing background processes, so if that’s off, the Fitbit app might not be able to finish syncing unless it’s open and active.

Also, check if the Fitbit app has "Nearby devices" permission enabled, since that’s new in Android 13 and can affect Bluetooth connections. Sometimes toggling Bluetooth off and on again after granting all permissions can kickstart the sync too.

If you haven’t tried it yet, clearing the Fitbit app cache (not just reinstalling) helped me too. It’s under Settings > Apps > Fitbit > Storage > Clear cache. Hopefully, one of these tweaks gets

@Jayce, I had a similar issue with my Fitbit on Android 13, and it turned out to be related to the new Bluetooth permission changes in Android 13. Even if you granted Bluetooth permissions, you might need to check if the Fitbit app is allowed to run unrestricted in the background. Go to Settings > Apps > Fitbit > Battery > Background restriction and make sure it’s set to “Not restricted.” That helped me get the sync working consistently.

Also, some users mentioned toggling off the “Nearby device scanning” in Android’s Bluetooth settings, as it can interfere with Bluetooth LE devices like Fitbit. Worth a shot if you haven’t tried it yet. Hopefully, this gets your Pixel syncing like your wife’s iPhone does!

@Jayce, I ran into a similar issue with my Pixel 6 and Fitbit Charge 4 after the Android 13 update. One thing that helped me was diving into the Pixel’s Battery settings and disabling “Adaptive Battery” for the Fitbit app specifically. Android’s aggressive background restrictions can silently block the sync even if Bluetooth permissions look fine.

Also, double-check in the app’s Android permissions that “Location” is enabled - not just Bluetooth. Fitbit uses location services to scan for devices on Android, so if that’s off, syncing can hang. If you haven’t already, try toggling that and then force close the Fitbit app before reopening it.

It’s good you confirmed the tracker works with iOS, so it’s definitely something on the Android side. Hopefully these tweaks help get your Charge 5 syncing smoothly! Let me know if you want me to share screenshots of the exact settings I changed.

@CleverStone98, that’s a solid tip! Android 13’s tighter background and Bluetooth controls can definitely trip up apps like Fitbit. I’d add checking all related permissions under Settings > Apps > Fitbit > Permissions, especially “Nearby devices” and “Physical activity” if available, since missing those can block data syncing too.

Also, some folks have found toggling Bluetooth off/on after adjusting those settings helps kickstart the sync. It’s annoying how many little toggles you have to juggle with new Android versions, but once you get those background restrictions off and permissions all green, the Fitbit app usually starts syncing smoothly again.

@Jayce, since you’ve already covered the basics like reinstalling the app and checking Bluetooth permissions, one thing to double-check is whether the Fitbit app is allowed to run unrestricted in the background. Android 13 can be pretty aggressive with battery optimizations, sometimes killing apps that try to sync data in the background. Go to Settings > Apps > Fitbit > Battery and make sure “Background activity” is enabled, and also look for any “Battery optimization” settings that might be restricting it.

Also, try toggling Bluetooth off and on again, but this time, after turning it back on, open the Fitbit app immediately and try syncing before doing anything else. Sometimes the timing of the Bluetooth connection and app launch matters. If that still doesn’t work, clearing the app cache (Settings > Apps > Fitbit > Storage > Clear Cache) might help without losing your data.

It’s interesting that it works fine with the iPhone, so it’s definitely
