update tracker software - says battery empty, but my Charge 2 is fully charged

[Pinkqueeny]

As of 8/16 my Charge 2 can't be located by the android phone app, even though the device is fully charged. So, no, I cant update the tracker software

The usual things to try when you get syncing / connection issues are:

• restart phone
• restart fitbit using this procedure: Help article: How do I restart my tracker?
• restart fitbit a few more times (it doesn't always work)
• "forget" the fitbit in the phone's bluetooth settings
• go through fitbit's troubleshooting guide at: Help article: Why won't my Fitbit device sync?

If none of those ideas work for you then it’s probably best to contact customer support via: contact.fitbit.com
