I’ve had one version of the Fitbit or another since 2012. I’ve lost or broken probably 4 or 5 of them. All of them were my fault. Except the latest….
For some reason the Fitbit Flex’s design makes the charging contacts get smudged and dirty VERY easily and prevent charging. This has happened 5 times in the last 9 months and I’ve actually returned 3 of these to Best Buy because of it.
Most of the time you can fix the issue with the following solutions:
- Rub the Fitbit charging contacts with alcohol swabs
- Rub the Fitbit charging contacts with qtips doused in vinegar
- Clean the Fitbit charging dongle with alcohol swabs
