I've seen a few multiples but far more sporadic updates - completely lost the 10 minute timing since the update. Not in health either, so they've presumably borked something.
 
Maybe they tied it to your movements? There's little chance your heart rate will change unless you're moving around a lot.

That's what I think as well. I will definitely try this in the evening, when I will move quite a lot. Now, the readings are sporadic and irregular, but also I have to say that I am not moving almost at all. So, difference between HR measurements might be like 5-10 bpm, which is almost nothing, since my average bpm is about 70. :)

Actually if our idea is right, then Apple has found very good solution for saving the battery. Why should AW take measurements every 10 minutes, when the difference is just few bpm, since there is no movement of the watch itself (and probably no movement of the owner as well)?

I thought of that but some people aren’t getting updates for 1-2 hours or more. It would be nigh on impossible for your heart rate not to change in that period.

If it’s not a bug surely Apple would have put this “feature” in the OS release notes?

I agree. Definitely a bug. I've clocked 1 minute of exercise today when I'd normally have 15-20 by now.

If this is true then they need to change the information about the HR sensor on the site.

Taken from Apple:

The average heart rate is 72 beats per minute (bpm). As you exercise, your muscles need more oxygen, and your heart beats faster to deliver it. During workouts, the heart rate sensor in Apple Watch measures your heart rate and displays it right on your wrist. You can also check your heart rate at any time using the Heart Rate Glance. And throughout the day, Apple Watch measures your heart rate every 10 minutes and stores it in the Health app. All this information, as well as other data it collects, helps Apple Watch estimate how many calories you’ve burned. And by checking your heart rate during workouts, you can see how both your intensity level and your heart rate change over time.

All right, then. I didn't notice that Apple wrote something like that on their page. So, it is a bug and we cannot call it as a feature. :rolleyes:

Never mind, I will test it this evening anyway and report here my findings back.
 
Is anybody else seeing multiple heart beat reads for the same time in the Health app? Going back through my log, it looks like this started on 19 May - I think the day 1.0.1 came out?
I noticed it too but it was during my workout.
 
My watch no longer checks every ten minutes either. It seems to be ONLY if I look at be glance or if I'm in a workout. Very disappointing :(
 
Just unpaired my watch and set it up as new. No change - the HR measurements are erratic and not at all regular.
 
I'm getting multiples of 12 now and erratic time gaps. Everything looked fine on Health before the update but it appears to have affected the pre-update readings too starting with multiples of 3 from 10 May onwards.
 
My issue with the HR sensor was a little different and occurred before the 1.01 update.

I noticed during workouts that my HR wasn't being measured at all. When I looked at the HR glance it would attempt to take a measurement but fail. Then I noticed the green LED's were not turning onwhen it was supposed to be measuring.

Additionally, when I took my watch off it would remain unlocked (wrist detection was not working). After restarting my watch, everything was back to working as normal.
 
Please post feedback to Apple about this bug at the link below...

I don't think we should second guess Apple about HR readings and assum this is a SW bug. I checked my data before and after the SW update. During workouts, HR is taken about every 5 seconds, if you are moderately active, it takes it every 10 minutes or so, if you are just sitting around, it takes it much less frequently. Lastly, if you take a HR reading using glances, it continues to take readings while visa pe and that explains why you see multiple readings when not exercising. This all makes sense to me, but keep in mind, I did reboot everything after the update.

Apple is making changes to impove things and has experts on staff that provide advice. For us to make assumptions based on no real knowledge of the science that goes into it is ill advised in my mind.

This isn't an improvement in any sense. Yes it saves a little battery but the impact it has had on the AW being able to accurately measure activity is significant. No way would Apple have done this intentionally and without mentioning it in the Update notes.

Sorry ... I have to disagree. The HR monitor worked as described in Apple's own documentation up until the update.

https://support.apple.com/en-us/HT204666

It specifically states that HR measurements are taken every 10 minutes when not in workout mode .. That isn't happening now for many of us. Unless and until they change that documentation I expect it to work as described and take regular readings. It says nothing about being moderately active for the 10 minute readings.

Well, sounds like you're the expert... But maybe you forgot that "activity" is sensed by the watch when you move around and HR is used more for measuring calories burned.
 
As you can all hopefully see, getting a little bit of everything in here. Seems to have a mind of its own now.

It's definitely a bug:

This was just reported on the apple forums:

"I just received a phone call from someone at Apple about this issue after I posted about it on Twitter. They took all of my information, spent about 30 minutes fact gathering, and has had me send them my heart rate information from the Health app to help them diagnose the issue. I was promised a follow up in the next couple of days with an answer to resolve the issue.

In going through the data, we found that it is not reading while actively moving. While sleeping or being very sedentary, it is reading every 10 minutes as it should. However, while even walking while on the phone, it was not reading for well over 30 minutes or more."

I got my phone call with Apple, spent about 20 minutes on the phone, collected my heart rate data, said they are working on it. Nothing else really. Fingers crossed for a quick fix :confused:
