I don’t want to oversell this solution. But let’s face it, you can lose hours and you probably will if you start rummaging through Fitbit’s own community forums on the solution of what to do when your Fitbit Charge or Charge HR doesn’t sync. You pick up a lot of bad and irrelevant and desperate advice.
What worked for me – the long story
Obviously there can be many reasons this may be happening: Bluetooth is off, Bluetooth pairing has been dropped, perhaps low battery, but those ar things you’d think of on your own, right, and anyway they’d be accompanied by other symptoms.
I have a Windows phone. Fitbit has an app through the Windows store. The syncing has always been very finicky. With my Charge HR I would sometimes have to try and re-try the sync for several minutes. Other times it would work right away. I couldn’t use either my home laptop or home desktop computer – both Dells – because the Windows 10 upgrade I did seemed to have wiped out the Bluetooth driver.
Then one day my spouse bought a Fitbit Alta and the helpful guy at Best Buy “helpfully” added her Fitbit and all her information to my account. You see I had commandeered her Samsung phone as well in a desperate attempt to find some device that would sync my Charge HR. It was a total mess. One day her steps overrode my steps and got synced backwards to my Charge! And it was 6000 steps fewer! So I got the idea to log out of my account. I logged back in and the sync worked quickly (quick means about 30 seconds in my experience). Since then I’ve done that a couple more times and both times I was able to sync right away after logging back in.
For Windows Phone when you can’t sync, and see the message Tracker disconnected when you know full well it has good batteries, it helps to log out of your Fitbit account and log right back in.
Syncing Fitbits is a finicky business in my experience. Their online help is mediocre and will just as likely lead you down the wrong path. Oh, and the wireless dongle that came with my Charge doesn’t fit the device! But I still like the devices overall – guess I got used to them. hopefully this trick to sync a Charge or Charge HR will help someone.
But don’t get me started on what happens when your battery begins to go.
