Battery drain of my Wear OS smartwatch

I have a Oppo Watch (Wear OS) and I have the Sleep app installed on it.
I go to sleep with 100% battery, and when I wake up it’s at 6%. What could be causing this much battery drain from the app?
I have been using the app for the last 4 days. In this 4 days, I have tried switching off some options (Oxygen reader, wi-fi from the watch, etc.) and I see no improvements. I don’t know what else I could do.


There are some statistics of battery drain in Wear OS app. Try to look there.

I checked before posting and the battery drained 94% but the statistics only showed 20%.

OK. I recommend you to go to the SaA app on your phone and send a bug report. It will send some logs and it can help the devs to identify the problem. Also they are much more active there.

Ok thank you very much!

Same here, why Oppo Watch has this draining battery issue?
