Apple “explains” why Watch OS 1.0.1 no longer records heartbeat exactly every 10 minutes

It took a few days, but today Apple has updated a support article on reading the heartbeat of Apple Watch which “explains” why, after installing the Watch OS 1.0.1, the watch no longer necessarily records every 10 minutes.


The quotes have a reason to be a. Before, the support article started like this:

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.

Now, Apple has changed to (emphasis added):

You can check your heart rate any time using the Heart Rate Glance. And when you're using the Workout app, Apple Watch measures your heart rate continuously during the workout. This information, as well as other data it collects, helps Apple Watch estimate how many calories youve burned. In addition, Apple Watch attempts to measure your heart rate every 10 minutes, but won’t record it when you’re in motion or your arm is moving. Apple Watch stores all your heart rate measurements in the Health app.

Briefly and in good Portuguese, the “novelty” is that, as of Watch OS 1.0.1, the watch does not register your beats if you are moving or your arm is moving.

Apple simply "threw" this information in the support article, without explaining exactly why the change was made. Thinking fast, I can conclude that it would be a measure to save battery but it is something that, in general, the owners of Apple Watches have been positively surprised.

It is worth noting that this all refers to the use of the watch during the day. When you are actually exercising, it does record your beats every 5-10 seconds and that hasn't changed in Watch OS 1.0.1.
