The battery on my gear s3 started to drain really fast, lifetime is around 12hrs now and my normal battery life is around 3days. I havent updated it or the phone app, havent changed any settings it just kinda happend. I have tried most things people say to do in similar threads to no effect. Those thing include hard reset, wifi off, location off, telemetry off. in the battery manager it shows that my watch face is consuming tonnes of battery but that cant be correct because i use a dark simple face and havent changed it in months.
