Have you checked whether your watch comes up as duplicate devices in Settings under Health app and then Devices. Mine comes up as two devices: 1 paired but has no data, 1 unpaired but has all of the active data. I think it’s either a hardware issue that they missed because only few people have this issue or a communication issue that is software related. When there are two devices showing that means the watch has issues communicating with the phone and it can drain the battery.View attachment 875711
I had this problem back when I owned my old Series 3 and then ended up resolving with software updates. Now with my new Series 5 the same problem happens. Even if you just saw one watch connected, over time it would appear this second watch. I have restored, unpaired, re-paired multiple times and the same issue appears. In my case though, although battery life is not the best for sure in series 5, I have a drain of about 2-4% per hour which is not bad at all. I have everything on besides “Hey Siri” and some “control” over the background app refresh. I sleep with my watch for sleep tracking with autosleep but my watch would be with no bluetooh connection, then in the morning I turn everything back on and I’m down to around 90% battery at the beginning of my morning. If I do a swimming workout the battery would drain around 10% and at the end of the day I have around 35-40% battery left. This seems super hard to track as everyone has a different experience. What I can really say about this year’s software releases is that they don’t have the quality we used to see in the past...I know there are tons of processes and new features every single OS release. Just my two cents.
