Sync stopped with sense to iphone app

[elaineco]

My Sense suddenly stopped syncing to iphone13 and to PC desktop. All software up to date. Tried turning off/on phone, force quitting Fitbit app on device, unconnecting and pairing again, turning Bluetooth on and off... nothing works. Sync starts, hangs for a while then stops. Please help. I am addicted to my daily stats!

I know you said "unconnecting and pairing again..." but did you do that through the FitBit app or through Bluetooth settings? Connection issues are usually fixed for me by deleting the Sense and then adding it again through the Fitbit app.

UPDATE: So, after repeatedly trying everything and nothing working for a few days, suddenly, i noticed the app was synching! hopefully it has rectified itself somehow. 

[elaineco]

yes, I tried that and it didn't seem to work. However, for no apparent reason, my Fitbit is now synching again. Hope it was a one-time temporary blip. Thank you for replying.

@elaineco Glad it's working again. 👍🏼

I have a sense that looses Bluetooth connection to my iPhone several times a day.  
Forgetting the watch in Bluetooth settings and re-pairing will connect for a while. I used to have ‘on wrist calls’ enabled. But it’s too much of a hassle to reconnect several times a day.  This started about 2 weeks ago.  
Both the phone and watch are up to date.  
Battery drain had started too.  Used to be able to get 2 days.  Now it’s barely 1 day.  

I’m about ready to call service.

@Cliffg Welcome to the Fitbit community.

What are the resting of your settings? I can get 4 whole days with these settings:

Brightness dim, screen wake motion and button, always-on display off, snore & noise detection off, SpO2 on.

The biggest battery drainers, especially overnight, are the snore & noise detection and SpO2, but more so the snore & noise. With it on, I lose around 20% over 7 hours of sleep. With that option off, I only lose around 6-8% over 7 hours of sleep. I had it on for over a week and I don't snore and noise is minimal so it wasn't worth the drain. If I turned off SpO2 I would definitely get 5-6 days. I keep that on because it's part of the health metrics.

Have you tried a factory reset?

[Cliffg]

SPO2 is on.  Brightness is medium.  Display is set for auto. 
I used to get 2 days plus.  Now it’s just over a day. 
the Sense has been factory reset. The app has been removed and reinstalled. 
I believe the loss of Bluetooth is causing the drain. 
Nothing seems to help the Bluetooth.

@Cliffg How about the snore and noise detection? 

It's possible it's a connection and/or syncing issue. How do you know it's lost connection? Are you seeing the phone icon with a line through on your Sense?

Looks like this at the top middle.

[Cliffg]

I do not have snore or noise turned on.
I’m using an IOS device

@Cliffg And how are you aware of the connection lost?

[Cliffg]

I get 2 indications that Bluetooth pairing is lost.
First the watch screen that shows battery %, display on, do not disturb etc. will have icons at the top flashing line throughout phone and battery %.
And I will get a message that Bluetooth pairing has been lost.
If I check phones Bluetooth settings it will show sense and not connected

@Cliffg Okay the first, watch saying it's diconnected with the phone icon and line through it is the true telling it's not connected.

Bluetooth settings won't show it's connected.

Here's a screenshot from my phone and it's definitely connected. The way to check on the phone is really through the Fitbit app. If it's able to sync, then it's connected.

Now when your watch says it's disconnected, your phone is on you or within Bluetooth range which is around 30+ feet?

[Cliffg]

Watch and phone are less than 10 foot apart.
This happens multiple times per day with the watch remaining within 10 foot of my phone.
Both the phone and watch have sufficient charge to maintain the Bluetooth connection

@Cliffg Yeah I never lose connection unless I walk far away and it automatically reconnects just fine. It's kind of difficult to pinpoint what could be the issue for you. It can be a hardware issue or software issue on either the Sense or your iPhone. Your iPhone is fully updated? What model iPhone is it?

[Cliffg]

Phone is a 12 pro max.
Yes fully updated. Same with the watch.
Have no issues with other Bluetooth devices.
Car will reconnect with no problem.
Watch disconnected from phone and I always have to restart the Fitbit app and forget device in Bluetooth to get it connected again

@Cliffg At this point, then sounds like you need to contact customer support, let them know all the troubleshooting you did, and if you're within the 1 year warranty you can get a replacement.
