Phone dying quickly using Sense 2

[1GinnyME1]

I'm not in a position to have my phone die quickly at work due to the Sense 2 software not being updated but my phone updated with the latest version. I'm at the point of going to Galaxy or Garmin rather than dealing the constant issues with the Sense 2. I've been a member of Fitbit since 3/2014. If Fitbit can't keep up with the latest software, what's the point?

Hi @1GinnyME1 - just to be sure it is not a temporary issue with syncing 

Logout of the Fitbit App and swipe off the active window and in Android clear the storage cache and force stop it and then restart the phone.

Restart the watch by holding the button for 10 seconds till it vibrates and the logo appears and wait for it to start.

Login and wait for any pair, link or Fixit prompts and sync.

If you still have a phone battery charge issue to furtger eliminate syncing as the cause try with the phone Bluetooth off.
