Charge 3 battery draining fast

[Sdy05]

I’m charging my Fitbit over night then it just goes dead, have restarted it, still dies? When iv charged it can sync it with the app but then just dies again?

Welcome to the Fitbit Community, @Sdy05.

Thanks for the details shared in your post and for already trying to resolve the issue. I recommend trying the following:

1. Log out from the Fitbit app.
2. Reboot your phone.
3. Log back into the Fitbit app and force quit the Fitbit app.

You can find our tips to maximize your tracker's battery life in Can I extend my Fitbit device's battery life?

By the way, I've moved your post to Other Charge Trackers board so we can keep our forums organized.

Hope this helps!
