Charge 5 is showing the wrong time after being charged

[Maikku]

My Charge 5 was completely empty before I left it to charge during the night. In the morning it showed minus four hours and 20 minutes the real time. What do I do?

Welcome to the Fitbit community, @Maikku!

It seems that your Charge 5 didn't have the chance to sync with your Fitbit app after having been charged as your device's time is set up whenever you sync it. With your Fitbit device nearby, open the Fitbit app on your phone and tap Today. Press and hold on the app screen, and then pull down on the screen to sync manually.

Hi there, @Maikku. Welcome to the Fitbit Community Forums. Thanks for the details provided in your post about the issue with your Charge 5. We're here to help you! 

As @Talahthas has mentioned, please keep in mind that your Fitbit device may show an incorrect time if it hasn't synced or has been unpaired from your Fitbit account. Your Fitbit device uses the time of the device you're syncing with. Since you've recently recharge it, maybe your Charge 5 just needs to sync to update the time. 

If you've tried the above but to no avail, make sure you're not running into syncing issues. For more information, see Why won't my Fitbit device sync? 

If the issue is still not solved, but you can confirm that your Charge 5 is syncing,  I recommend changing your time zone to a completely different one, sync your device, put the correct time and sync again.
