@Tharvey Welcome to our Community! You can select to have a phone or email (or both) notifications sent when your Flex 2 is low on battery. Just take into consideration that if you activated this feature after your tracker reached the threshold (20% of the battery) then you won't get the notification until next time the tracker reaches it again. You can check your notifications settings to activate these notifications.
Let me know how it goes!

@Tharvey Happy to hear that you received your notification! Now we know it is working find so you don't need to worry about having your tracker run out of battery without a warning. Just make sure to sync your tracker periodically if not you won't receive the notification.
I'll be around!

My flex 2 was been at about 60% battery midday today and died without warning by the evening. I know I put my battery through the paces, but most of the time I get my low battery warning as expected. Why would I not receive the low battery warning?

@sharkbait703 Welcome to our Community! Have you been syncing your tracker? If you haven't then the system won't know that the battery has drained and won't be able to issue any alert. If the tracker has been syncing have you used the Swimming detection option, this option will use more battery so this could be the cause. Finally if these aren't part the of the issue try restarting your tracker by doing the following:
1.- Plug the charging cable into the USB port on your computer or a UL-certified USB wall charger.
2.- Remove the pebble from the wristband and press it into the compartment on the charging cable. The pins on the charging cable must align with the corresponding pins on the back of the pebble to lock securely in place.
You’ll know the connection is secure when the pebble vibrates and you see the indicator lights blinking.
3.- Find the button on the charging cable below the tracker compartment.
4.- Press it three times within five seconds. The tracker vibrates each time you press the button. A few seconds after the third press, all the lights will flash simultaneously. This means the pebble has restarted. If you miss the light flash but notice the pebble has resumed charging, that too is confirmation that the restart was successful.
5.- Remove the pebble from the charging cable and insert it back into the wristband.
Let me know how it goes!

I have a Flex 2. I get the low battery in my email. I have checked that I want them on my mobile. But I cannot find anywhere to input my mobile number!! Any ideas?

@lsb0730 It's great to see that you've visited the Fitbit Community! The phone notification won't send a text message, it will notify you through the Fitbit app installed on your phone when you sync your tracker and it gets an update on the battery status. If you don't have the app please download it from the App or Play store.

I have the app and I see the battery indicator. Strange wording in the settings, but this was helpful. Thank you.
