Why does my sleep tracker vary?

[BriAnne5]

Since the new sleep tracker update, (which I love by the way) there have been a few nights that my sleep is tracked using the old method. Why is that? And how can I make sure it only tracks using the update?

Hi @BriAnne5,

I had that happen to me during the sleep update. It fixed itself after a couple of times of using the old way of tracking. I don't think there's anything you can or have to do on your end. One thing to note is that naps and sleep less than 3 hours are still tracked in the old method, probably because there's no REM during such a short sleep.

Hi WavyDavey,

Thanks for your response. I found you were right about the naps and short
sleeps; until this morning. I got 7+ hours last night and when I went to
check the app, it calculated in the old format again. Just strange!

Thanks again!

I have the same problem. The suggest solution, installing the update, hasn't fixed it. It has been over a month and my nightly sleep sometimes still shows up in the old style. Randomly.

I've had the Charge 2 for about two weeks now, and only on two occasions have the new format sleep graphs been generated. Last night I tried having the band a bit tighter, as I thought this would ensure that my heart rate would be monitored more reliably, but still the old format appeared.

Not quite sure what to make of it.
