Duplicate Apple Watch in the Sources devices list

Got the Apple Watch Series 5, and paired it to the iPhone without any restore. But I found two Apple Watches in the "Settings - Health - Data Access & Devices". One of it says "No data found" and the other one says "This Apple Watch is no longer paired with this iPhone", but this one is still updating the activity data. I am currently on the iOS 13.1.2 and watchOS 6.0.1.


Is anyone here experiencing the same issue?

Over the last two months, I had my phone and my series 4 watch replaced. One would think that with that the issue has been solved. Wrong! at the Apple Genius Bar (Apple Ingenious Bar, rather) they tried to explain to me this way. Explanations are in chronological order:

  1. “there is no issue with your watch”. (Proved them wrong. Showed them the inconsistent data between health app and the duplicate device list)
  2. “There COULD be an issue with the watch”. (They sent it off and email came back: We will be replacing your device.)
  3. Since the issue was still there, they said “there could be an issue with your phone” so off they sent my phone. A week later message comes “We will be replacing your device” (At this point i was laughing my head off. Fine with me, new watch, new phone...they are absolute idiots.)
  4. When I paired the new watch with the new phone, I used a different Apple ID, wiped clean, no health data...still two devices in Data Sources. What it also does, connection between the watch and the phone is slow and Siri often takes a minute to respond. At this point I could not be bothered. However, I did notice a difference: under watch OS 5 there was only ONE device listed. The moment I updated the watch OS, immediately 2 watches came up. And the very same thing happened with both Series 4 Apple Watches. So IT IS SOFTWARE RELATED ISSUE. My boss just got his new Apple Watch and new iPhone. He never had an Apple Watch ever. Paired the watch and he also has duplicate devices in the Health app data source/device source. 1 devices actively paired with the phone but does not receive any data. 2nd device, “no longer paired” with iPhone receives all data!

Lesson: Apple both employers and employees do not have the backbone to say: Yes, the operating system has a major bug. We don’t know how to fix it at this stage. We are sorry.” No, instead, they pretend there is no problem, no responsibility, no integrity. Only lies, lies, lies. At least when Steve Jobs was at the steering wheel, he had the guts to admit. Mr Cook is always cooking up something that people eat up and then get sick. But we are fed up. No more Cookies, please!

I am experiencing exactly the same issue. In addition - after a few weeks of use the battery on the watch starting to go downhill - not sure if related - but has something to do with the health database as active energy sync start lagging by hours.


I've went as far as resetting both watch and the phone (not from backup) - and still end up with 2 watches every time I pair a watch nomatter what I do. It's not random - it's reproducible every time. My friends watch/phone however doesn't seem to have this issue.

For me doesn't matter - new or backup produces the same 2 watches, the same down the road battery issues and the same down the road activity sync lags. If you look under privacy / analytics there're many many many log files with healthd being stuck with sqlite stack trace on Core Data (which is the worst framework Apple put out ever - that so poorly thought of that it can't possibly work right by design and source of a million bugs btw)

I also have this problem.

I reset the phone using the side button and crown button and switched my phone off at the same time. Waited a few minutes and restarted phone.

data now transferring!

In settings, there are still 2 watches and still saying one with no data is paired and one with data not paired- but it is actually getting the data now. 🤯

Yeah - once the 2 watches problem appears there's no way to get rid of it (even completely resetting both the phone and the watch and not from the backup doesn't fix it). My guess there' something set in the iCloud account that gets restored during the install (disabling health in iCloud doesn't help - so it must be something very core to the account state itself).


The bad part here is that you start seeing progressive battery life degradation and active energy sync delays after a while - and those are likely connected (you could go to Privacy/Analytics and observe increasing number of healthd errors complaining about CPU overuse stuck deep in sqlite stack - both from the phone and the watch).

One thing - keep an eye on the battery life in about 3 weeks after the reset. You should notice a progressive battery degradation that gets worse towards the end of the day. By week 5-6 the watch will become unusable (requiring multiple re-charges just to get through the day) until you reset it again.


You could also look under Settings/Privacy/Analytics and if you notice a lot of healtd CPU overuse logs - that's another indication. The battery problems will be accompanied by active energy sync delays (i.e. after a walk or a workout you will notice that the watch is seemingly not syncing - although all other functionality will appear normal - i.e. messages, photos etc)
