Snore detection sonar vs. wearable

I usually wear a Galaxy Watch to bed and use it to track my sleep, but sometimes if my watch battery is low, I’ll use sonar. Ive noticed on the sonar nights, significantly less snoring is detected than on the watch nights.

My understanding is that the snore detection is done at the phone level, so it shouldn’t matter how I’m tracking my sleep cycles. Is that correct?

Could it be that wearing the watch has an impact on how I sleep and is actually influencing how much I snore? Or does the snore detection work differently when I use sonar vs a wearable?

Hello Lisa, the sonar signal uses the mic and the speakers, so it can influence the snoring detection. Is the sound level detected by the app approximately the same, or it differs as well? Could you please contact Thank you.
