I’m also having issues. I brought an iPhone 16 pro and I can’t sync my Fitbit sense 2 to it. My husband just has a Samsung S24 and it will connect to that so I know that it’s a syncing issue with my iPhone.

I didn't get a iPhone I just replaced the phone that broke with the same make and model. It's always been on android. My mate always had issues with the connection with iPhone

It's good to see you participating in the community @blinkie88 and welcome to the community forums @WHALEN3.

Thank you for taking the time to share the inquiry regarding this difficulty with your Sense 2. 

Please, make sure that you have removed the watch from the previous phone's Bluetooth, as the watch could be connecting to it instead of the new phone and make sure [more likely] that there is no battery savings enabled on the iPhone which is shutting down the Fitbit App or associated services from running in background.

With that been said and if you haven't done so yet, I'd recommend trying the following steps in the order listed:

• Unpair your Sense 2 from your phone's Bluetooth and Fitbit app.
• Unpair other Bluetooth devices that you may also have paired to your phone's Bluetooth settings.
• Force quit the Fitbit app.
• Turn off other Bluetooth connections when not in use. This can help to prevent connectivity issues or Bluetooth interference.
• Shut off your phone and turn it on after 1-2 minutes.
• Turn on the Bluetooth on your phone.
• Plug it into the charging cable and open the Fitbit app.
• Set up your Sense 2.
• If there is no connection, restart your Sense 2.
• Once your Sense 2 is paired and syncing, please proceed to set up your other Bluetooth devices to your phone again. 

With the steps above, what I want you to do is to pair your Sense 2 first to your phone's Bluetooth settings before any other Bluetooth device is connected to your phone.

@blinkie88 on your old phone, did you disconnect the tracker through your phones Bluetooth screen? If not, then the tracker is still connected to your old phone. If the phone is turned off, then we don't care anymore. 

However if you removed the tracker from your fitbit app, which removed the tracker from your fitbit account. When switching phones, never do this, you will now have to setup the tracker as if you bought it this morning. 

Normally turn the old phone off. Load the app into the new phone, log into your account. Accept any requested permissions. Now setup notifications.

@WHALEN3 if you tracker is syncing with your husband's phone. On his phone: 

• Log out of your account
• Remove your tracker from his list of connected Bluetooth devices
• On your phone log into your Fitbit account 
• Accept any requested permissions
• Your tracker should sync through your phone. 
• Now setup notifications
