Updating your Fitbit Charge 2
We occasionally make free feature enhancements and product improvements
available through firmware updates. We recommend keeping your Charge 2 up to
date.
When a firmware update is available you’ll see a notification in the Fitbit app
prompting you to update. When the update starts, a progress bar appears on the
tracker and in the Fitbit app until the update is complete.
Keep your tracker and mobile device close to each other during the update process.
Note: Updating your Charge 2 takes several minutes and may be demanding on the
battery. For this reason we recommend updating while your tracker is fully
charged or plugged into the charging cable.
