Sense 2 keep showing logo

[mark8888]

My sense 2 keeps showing the logo. When I try to reboot, it shows a red cross. Sometimes after charging the problem goes away, but after less than 12 hours the problem comes back again. Is it because of the battery problem? 

Everything is updated, i tried factory reset, still doesn't work. Now the watch is basically useless, it won't last for more than 12h.

Thank you for sharing these details about the difficulty that you are experiencing with your Sense 2. Sorry to know the issue. 

Please make sure to follow the steps listed here, below:

I have the same issue as the OP. I've also performed each one of the steps list and the issues remai. It works during the day but will flag the fitbit logo flashes on randomly at nigh and by morning stops working completely. I've also performed each one of the steps list and the issues remain. 

What else is the problem now?

I am having the same or very similar issue. I can put it on the charger and the battery is not dead, but  still somewhere over 50%. It will fully charge and then work for about 12 hr, but only connecting to a charger will turn it on. According to the release notes, there should be a firmware update available but it doesn’t show up ever.
