Garmin Add-on for Sleep app

The app provides inconsistent data sync during sleep tracking. Sometimes it records full HR, HRV and SpO2 during the entire sleep, sometimes it records the first half or less and then stops recording data from the watch. The last couple of nights it recorded literally nothing. I've already disabled battery optimisation, disabled pause app when not used etc, but things didn't change. Update: I checked all system settings and ensured that app has no restrictions or battery optimization. No change.

The app destroys my Garmins battery. My watch has recently only been lasting a day on my Fenix 5x.. It used to last a week or so. This issue needs to be resolved. Otherwise, I enjoy the data collection / sleep tracking capabilities. Edit: I've updated my rating to one star, as I can't deal with the battery drain anymore. From half battery to less than 10% in one night of sleep. This battery issue has to be resolved before I can recommend this app to anybody.

It feels so unpolished, like a beta version even though it was released in 2017! My watch used up 30% battery compared to 10% without it, which is at least bad! My Android Wear watch was using much less battery! And the worst is that the data is all wrong! There is a recurring pattern of no sleep data (red) and in-between light sleep; for sure not valid data. I will disable the add-on until at least the data issue is fixed. The developer can certainly ask for any information I can provide.
