Charge 6 not tracking sleep stages

[Sagark]

Charge 6 is not able to track sleep stages.

It's just tracking 3 states: Awake, Restless and sleep

It's not tracking stages like Deep sleep and Rem

Also it's not calculating Sleep score

@Sagark  , A warm welcome to the Community! Thank you for your message and information.

Please verify that the heart rate was recorded continuously and you don't see any interruptions during sleep time . This might happend if the Charge 6 moved during your sleep and cannot recognize the heart rate. 

The following conditions can also prevent the recording of sleep phases:

- You record your sleep using the app instead of the tracker's automatic sleep detection.
- The tracker's battery is almost empty when you go to bed (less than 25%). This prevents regular recording of your heart rate.
- You use the metal bracelet while sleeping
- You sleep less than 3 hours.
- The bracelet is too loose or too tight on your wrist. You should be able to put your index finger between the bracelet and your arm without much resistance so that your heart rate is recorded regularly and the sleep phases can be recognized.
