My heart rate reading are no longer every 10 mins following the update. In fact, I'm lucky to get one an hour. I'm sure Apple will fix this quickly.
 
This issue seems to be gaining momentum in the Apple world blogs - appleinsider.com has now picked it up too.

I suspect that a fix will be along sooner rather than later since this bug does adversely effect one of the AW's biggest selling points. Fingers crossed...

I wonder why there is not a Macrumors post on this issue
 
My wife finally received her SS watch yesterday.

Since 1.0.1 worked much better for me than 1.0.0 I encouraged her to update not long after getting it setup. I failed to really look at how her health data was flowing, but sure enough it is not flowing now.

This includes heart rate data, but also step data. The watch feels slow all the time when dealing with any health data.

For example, sometimes she can go on a walk, and if she is not "Recording" her activity, sometimes it can take a full hour for her steps to show up in the Health App or Activity App on the iPhone.

With my watch (42 white sport), this is near instantaneous. My watch does not always record heart rate every 10 minutes, but pretty close, and mostly consistently (also on 1.0.1).

On her's (SS 38mm), the heart rate data seems completely random, and when it chooses to update the iPhone is even less regular.

Hoping for an update soon, or her's will be returned/exchanged likely.
 
Definitely seeing this issue here too. It's gone from every 10 minutes to being very inconsistent. And yesterday evening there was a whole 6 to 7 hour gap with no data recorded. Hoping they get this resolved soon!

This is a strange issue. While reading all these complaints I went to my Health app on my phone and found the HR data recorded there every 10 minutes like clockwork so I thought "oh that's good that's one issue I don't have". But then I found that it only records that data while I'm at rest, sitting down. To check this I got up and went for a 20-30 minute walk and the last recorded time was prior to my having left the house. Sitting back down now it's gone back to every 10 minutes.

Now if I engage the exercise app it records every minute and actually multiple times a minute.

Even though this appears to be a bug it also appears to be deliberate. Almost as if it's been programmed to only record a "resting" heart rate unless you've engaged one of the activity/exercise functions in which case it records multiple times a minute.

Same here. Heart Rate reader works during workouts but otherwise only checks every 2 hours (mine ran at 9:40am and again at 11:40am according to the Health app). This is most likely the only reason I've seen about a 10% improvement in battery life on my 38mm Watch after the 1.01 update.
 
I thought when the Watch is not in exercise mode, it will attempt to take a HR measurement with the lower power IR sensor, and if it can't, then it simply won't take a reading.

That's why I'm wondering if it was deliberate. As I said above if I'm just sitting around at rest it's every 10 minutes without fail. Get up and move around, nothing, at least until I sit back down and watch an hour of tv or something that keeps me in the chair for a while. Engage one of the apps and it's every minute or more. That seems like a deliberate setting to me.

Not according to Apples own documentation...

The heart rate sensor can also use infrared light. This mode is what Apple Watch uses when it measures your heart rate every 10 minutes. However, if the infrared system isn’t providing an adequate reading, Apple Watch switches to the green LEDs. In addition, the heart rate sensor is designed to compensate for low signal levels by increasing both LED brightness and sampling rate.

No cos it's not like that for me.

If what was deliberate, Apple needs to update its own documentation on how the heart rate sensor functions. Plus I doubt the battery life gains would be appreciable .. You are still going to have to charge every day regardless.

I originally thought it was deliberate too and posted that belief as well. Now, however, I believe like most others that it is a screw up on Apple's part. Like what happened this morning is that I had occasional HR readings when sitting around and then washed my car for over an hour and no reading were taken during that whole time. That is just not an improvement regarding activity monitoring!

It is hard to believe that Apple didn't do a better job testing the SW update before releasing it.
 
Has Apple offered anyone anything when calling in and reporting the issue? Just curious. It's a pretty big selling feature to break down on us. Even if it can be fixed quickly.
 
Talked to Apple this morning about this issue. They insisted it was hardware and therefore overnighting new watch.
Why do I have a bad feeling I'll still have the same issue this time tomorrow:(


Got my replacement today. Came with 1.0.
Will not be updating until a fix has been made.
Everything back to normal with 1.0.
Reading every 10 min.

As others have said this is not the case for most. It doesn't matter if I'm sitting down resting or active I do not get consistent readings anymore. I always did before the update. I really doubt Apple would change the heart rate reading times without informing all the recent purchasers and keep this information on their site where it specifically says the watch takes heart rate readings every 10 minutes.

Mine is still every 10 minutes after the update

You are one of the few lucky ones. Be glad.

Sweet! I would stay with 1.0 like you are until a fix has been confirmed.

Hmm if you don't install the update to break your watch again Apple will think it was indeed a hardware issue.

I understand why you don't want to upgrade though.
