Charge 3 doesn't track sleep and it won't sync

[Cet1108]

Whenever I have to charge my charge 3, it won't sync up.  It also doesn't register my sleep or metrics.    I have to reboot the device& then pair it again.  

Its incredibly annoying as it only holds a charge for about 3 days now.  Its about 9 months old.

Hello @Cet1108. Welcome to the community forums. 

Thank you for the information and for the troubleshooting steps you've tried prior to posting. I'm very sorry for the experience and I'd like to recommend following the troubleshooting steps for syncing, in this link: Why won't my Fitbit device sync?

I also recommend performing a long restart to your Charge 3 to see if that refreshes the performance, this way your Charge 3 can start tracking your Sleep and therefore, your metrics. You can do this, by following the steps below: 

1. Connect the device to the charging cable. 
2. While the device is plugged into the charging cable, press and hold the button down for 15 seconds. 
3. The device turns on and shows a battery icon. Two vibrations occur: first a short vibration, then a medium vibration. 
4. The device turns off.
5. The device turns on and shows a progress bar and short vibrations occur. The progress bar completes. Note: A total of 7 short vibrations occur. 
6. Remove the device from the charging cable. The device shuts down.
7. Important: Plug the device into the charging cable again.

For the battery that is draining faster, please take into consideration that it can be affected by several factors. For tips about how to maximize it, please check: Can I extend my Fitbit device's battery life?

Hope this helps.
