Welcome to the Fitbit community, @Nicky16!

To improve sleep tracking with your Versa 4, I'd suggest setting a sleep goal and a sleep schedule. You also might get more reliable results by changing the sleep sensitivity for your device. For detailed information on all that please have a closer look here:

You also might try if restarting your Charge 5 will get things fixed. Before doing so you should make sure you've synced your device to not lose any data tracked so far. Also you should verify that the charging contacts on your device are clean and the charging pins on it's charging adapter are clean as well and can move flawlessly. In doubt, please have a look here:

Next please closely follow these instructions as timing is crucial for this procedure:

1.) Connect your Charge 5 to the charging cable which has to be connected to a reliable power source.
2.) Press the button located on the flat end of the charging cable 3 times within 8 seconds(!), holding each press for about 1 second(!).
3.) Wait around 10 seconds until the Fitbit logo appears on your device's display.

I'd like to point out that it sometimes requires more than one attempt to restart Charge 5. So, before throwing the towel, please give it another try.

I'll keep my fingers crossed.
