If I turn off Sync Modes with phone on Galaxy watch 6 classic, will Sleep Detection still work for snoring, HR, etc?

If I turn off Sync Modes with phone, will Sleep Detection still work?

Will my watch be able to record snoring, heart stuff etc?

Yes, but it can't record snoring unless the phone is nearby as it uses that to verify sounds
