Firmware Updates
We occasionally make free feature enhancements and product improvements
available through firmware updates. We recommend keeping Ionic up to date.
Updating Ionic can take an hour or longer and may be demanding on the battery. For
this reason, we recommend plugging your watch into the charger before starting the
update.
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 Ionic
and in the Fitbit app until the update is complete. For best results, make sure your
watch is charged and can connect to your Wi-Fi network.
Keep your watch and phone or computer close to each other during the update
process.
If you have trouble updating your watch, see help.fitbit.com.
