Charge 2 won't sync

[JBARRIE]

 Hi, for the past 3 days my charge 2 has not been syncing to my android device. I have tried force stopping the app, turning Bluetooth on and off, I have turned my phone on and off and uninstalled the app and it still is not working. I do not know what else to do please can someone help?
Thanks, Jane

My Charge 2 says "Battery Empty" and it won't respond to a restart, following your instructions.  I have uninstalled and reinstalled the app, and I am connected to Bluetooth.

Hey @LynnPar, welcome to the Fitbit forums! Thanks for attempt to restart your Charge 2. Let me ask you this, is it your Charge 2 charging when you connect it to the charging cable? If so, polease fully charge it. In the meantime, since your tracker still not syncing, I would like you to review all the troubleshooting in this help article: Why won't my Fitbit device sync? 

Let me know the outcome! 

[LynnPar]

Thanks for responding! No, it seems to have no response at all to being
connected to the charger. On my Fitbit app it says "battery empty," and I
don't get any response at all trying to restart it.

Thanks for responding @LynnPar! And thanks for trying what I suggested you. Let me suggest you to try something else. Please set up your Charge 2 as a new device. In order to do so, please follow these instructions. 

Let me know if that works!

Just tried to set up new account
Couldn't get past the "Power On" step, even when attached to the power
cord.

For the last several days the Fitbit app on my android phone has been showing a message that says "enable location to sync". This is a new "feature". It usually syncs even without location enabled. But what has changed recently?

[Rich_Laue]

Yes it is new to Android 6 @VdH, if you recently upgraded to Marshmallow then that would explain the reason that notification needs to be on. 

[VdH]

No idea what android version marshmallow is but have had the phone for more
than a year and have not made any changes that I initiated but did start
receiving the message 2 or 3 days ago.

oh well - message is annoying but as long as it continues to sync

My Fitbit doesn’t display anything. No numbers or anything. It’s just a black face. I know it’s on because it will vibrate, but I just can’t see anything. Tried plugging it in and doing what you told me to reset it, it vibrated, but no display. When I went to my Bluetooth and told my phone to forget the divorce, and I tried to re-pair my fibit to my phone, I couldn’t because I can’t see the 4 digit code to type into my phone to finish the pairing process. 

[Rich_Laue]

Removing the Fitbit from the phones Bluetooth will not require setting up the tracker. Removing the tracker from your Fitbit account by removing it from the app will only add more problems and require  setting up the tracker.

In any case if you have a black screen iv suggest contacting Fitbit.

I've used all these steps in your solution, but every 3 day's or so, the same thing starts over by not syncing.  Then it takes me about 30 minutes each time to uninstall the app, plug in the fitbit charge 2 into the computer, reset it, reinstall the app, then turn off my phone, then (wash, rinse and repeat), before eventually it will sync again.  It will sync for about 3 days, then I have to start all over...feeling very frustrated.  

[Rich_Laue]

Not knowing what type of phone, @klmcq it is hard to respond. 

Do you try to sync after each step? Whatever step works for you then that would be the first step to try next time.

Removing the app would be the last step I would try, the first step I do is to make sure that the app is up to date. 

Then I would turn bluetooth off/on

Restart the phone and the tracker, I think this is what you call a reset.

On an Android device, with the rare times I and my family have problems we find that clearing the Fitbit app cache is the step that works, and therefore after checking for an app update clearing cache is the next step. 

[hhensley]

How do you clear the cache?  I have this problem constantly.  Mine has not synced since November even though it says it is syncing constantly and using my phone battery up.  And I have tried reinstalling, restarting, removing from bluetooth, etc.

[Rich_Laue]

Not sure @hhensley your asking is about how to do something on your phone, but haven't included the phone type or what version the OS is. 

[PassFit]

Tried three times. Still 4 minutes. Bummer. It used to be 2 minutes, but I don't want to clean out cache. Would like to keep info. Seems like Fitbit has a reprogramming job.

[Rich_Laue]

Cache is simply the program taking a guess at what you may want to see next. It is not data but temporary files.

All of your Fitbit data is keep in the cloud on the Fitbit servers, there is no Fitbit data stored on the phone.

I'm not sure what the 4 or 2 minutes mean @PassFit

[PassFit]

Rich, I was referring to the clock error. It takes 4 minutes to synch. The clocktime is read at the beginning and used as real time. I was told by one person to reset all data. Another person suggested to restart. I tried it all. Still a 4 minute error. Why can't the synch software not read the time last. It is annoying to always have the time off by 4 min. In the beginning, one year ago, the delay was 2 minutes. The difference must be part of the accumulation of data.

@HeydyF I gave my mom my old Charge 2 when I received a replacement - the screen was cracked on it.  FitBit assured me that the old one still worked and could be transferred to another user, but I have tried hundreds of times to get it to pair with an account I set up for my mom, I've reset the device a dozen times, made sure it was the only device and phone in the room I was in etc. I can not get it to connect! 

Any possible help would be so so helpful!

Thank you!
Katey

[Rich_Laue]

@KateyBrie have you removed the Charge 2 from your phones Bluetooth, if you haven't, the charge 2 might still be connected to your phone.

BTW if you would like help with moms phone, it would be helpful to know what to of phone it is.

Another way would be.

In your phone, log into moms account

Setup the Charge 2

Log back into your account and remove the Charge 2 from your phones Bluetooth.

On Mom's phone she should then see the Charge 2 on her account and will try to sync

Do you lose all your data if you delete?
