Battery, syncing and resetting issues

[bellatmn]

My Blaze battery dies within 3-4 hours of being charged (yes, I leave it on the charger for two hours), the screen locks up, it doesn't always sync, it frequently vibrates even though no notifications are being posted, it has yesterday's data showing as today's (on the Blaze and on the dashboard on my phone, and on the website dashboard).  I previously had a Fitbit Flex, which was replaced once for it no longer syncing, but when it died a few months after the replacement I gave up on Fitbit.  A friend told me to try the Blaze.  I'm not impressed that after less than six months my Fitbit Blaze has died.  I have tried resetting it and that has not fixed the problems.

And now my Blaze has completely died. I put it on the charger and it immediately shows fully charged. I take it off the charger and the screen is dead.

A warm welcome to the Community @bellatmn, thanks for troubleshooting this by yourself!

I will be glad to help you with the issues you are experiencing with your Blaze:

• About the battery, please follow the instructions provided in this post.
• About the syncing, take a look at the Having trouble syncing? post and follow the steps provided there.
• About the not resetting and display issues, feel free to restart the device a couple of times more.

I hope this helps, let me know the outcome.

I"m unable to get the Blaze to take a charge so I can turn it on, much less reset it.  This is my third Fit Bit to die a quick death.

How do I return my Blaze?
