Comments on: How to fix Apple Watch heart rate monitor not working Unconferences, peer conferences, participant-driven events, and facilitation Sun, 10 Jul 2022 19:26:39 +0000 hourly 1 By: Apar Agarwal Sun, 10 Jul 2022 19:26:39 +0000 Same issue with my Series 7. Try wearing your watch 2 fingers up from the wrist bone: it worked for me. With my Fenix 6 I NEVER had this problem

By: Dino Frangos Fri, 04 Feb 2022 16:00:02 +0000 I still have my Series 4 Apple Watch – I workout every morning and have noticed over the years that my HR charts are exactly like the ones shown in Fig 1 (i.e. large gaps in the readings!).

Even sometimes when I do a 30 minute HIIT session, the chart will be blank as in Fig 2 (i.e. Chart Unavailable).

I haven’t yet tried opening the HR app first as suggested in the article so will give that a go.

That’s a good article, Chad — thank you for bringing it to our attention. Unfortunately, the problems I and many others have been having aren’t solved by anything mentioned in the article. My best guess these days is that the Apple Watch sensors simply have a hard time reliably reading heart rate for some people. I’ve only ever had one watch, a Series 3. One day I might upgrade, and it will be interesting to see if these problems still occur for me on a second watch.

Arienne – my series 3 was doing the same thing. found this article and it fixed it – had to go to settings on the actual watch, using the Digital Crown scroll down to Workout, tap it and then turn power saving mode off.

By: Csilla Rákosi Sat, 11 Dec 2021 18:12:05 +0000 I bought my Apple Watch Series 6 in March 2021. It worked flawlessly during my Nordic Walking workouts (despite lots of hand movements + hand straps for the poles!) till the middle of July. Since then, it either works properly or there are shorther or longer periods when it does not measure my heart rate – and it seems to deteriorate 🙁

By: Ashish Thu, 07 Oct 2021 08:40:52 +0000 Excellent article, Adrian.. and I’m reading this exactly 2 years from the date of publishing. (Happy Birthday?)
I have a series 3 and was beginning to give up on it since I faced the same issues in the last 3-4 months. This was both on treadmill and outdoor runs. Since this is an older model, I don’t have enough memory and refrain from upgrades. But let me try that first and then revisit the post. Surely, something will work!

Hi Roger,

Your experience mirrors mine. It’s so frustrating.

In June I posted a comment about my experience that my watch began to record my heart rate reliably right after I upgraded it to watchOS 7.5. However, this did not last long. But the same temporary improvement occurred when I updated it to watchOS 7.6.

For both these upgrades I had to do the entire backup -> reinstall OS -> restore from backup process, since my Series 3 watch didn’t have enough memory to do the upgrade “in place”.

So my current theory is that there’s some kind of memory management issue on these watches that is temporarily cleared when the watch is reset with a fresh copy of the OS.

However, I don’t want to reinstall watchOS every couple of weeks, so the problem remains.

By: Roger Young Sun, 05 Sep 2021 13:15:26 +0000 Bought my Apple Watch 6 in April 2021 and have just discovered that the heart beat monitor skips periods of 5 minutes during cycling workouts. Always when I have upped my work rate significantly. (Eg when attacking a hill).
Very annoying, as it is just these sections of the workout I need to analyse!

This is very interesting, and also correlates with arm movement for me. I have had a series 5 for a little over a year. I first saw the problem while walking on a treadmill and now see it a lot while doing apple fitness + rowing workouts. Scrolling back through my workouts, I do not see the problem with cycling, yoga, core, etc workouts.

I have tried reversing the watch so the sensors are on the inside of my wrist, cleaned the sensors, and sometimes have the watch band so tight it’s painful. I have contacted apple support. I hope this can be resolved, it’s frustrating.

By: T Fri, 09 Jul 2021 01:14:34 +0000 I also have this issue I started my walk app but even before I started walking it said it was 150bpm which is was not I would have felt that just standing around … also it only lasted there for 5 seconds then dropped to 85 bmp obviously not right I have also called Apple have had tickets with no resolution when I wore my Fitbit I had less problems but the Apple Watch is expensive so I would think they would want to help seems like a lot of ppl have the same problem
