New Heart Rate Sensor(s) on the Series 11?

[Jackbequickly]

Apple says the following in it’s details for the new Series 11 watch:

“Advanced sensors. Apple Watch Series 11 uses innovative sensors — including two heart sensors and wrist temperature sensing — to stay on the pulse of your health.”

Does this mean the HR sensor has changed from the S10 series? Hope so as mine drops out often. And no, I do not want to wear a chest strap for HR.

Isn’t this for the hypertension feature?

the hypertension feature is also available on the older models too, Series 9 and ultra 2 Both have it.

on the comparison page, the S10, S11, ultra 3 all say "Third-generation optical heart sensor" as does everything back to the S6, and all models of ultra. (hypertension doesn't seem to be on every model with 3rd gen)
all models of SEs say second gen.

then get the new AirPods Pro, or the beats with HR sensing in your ear.

Do you have tattoos? is your strap tight/loose enough? is the back dirty? all of those will affect the HR monitoring of the watch

oh cool, I didn’t know that. I’ve just done the comparison feature on their site and there is literally no reason to upgrade from S9 (no complaints here, I’m pleased that devices have more longevity)

So it has the same sensor. I have the newest AirPods but can’t tolerate the Pro models. No tattoos, back of watch is not dirty. I adjusted the strap and moved at all over my arm. In cold weather I can get it to work with the watch located on my inside wrist. During a workout, it starts measuring my HR but quits and I have to adjust and readjust.

Was just hoping for a better or improved sensor. Not a deal breaker as I could not do without my Apple watch

Have you had this on all watches or just your current one? It sounds defective.

Unfortunately, all.

Unfortunately, all.

I’ve always had the same issue with the AW (Series and AWU). I get HR dropouts with them while running that I don’t get with a Garmin or Coros.

Huh, that’s weird. I’ve literally never had that on any of mine, so it’s weird that it happens across multiple watches if someone has it

While I’ve never noticed such — though I don’t do a lot of regular gym work — during weightlifting, yoga, and other activities there can be a lot of arm and wrist movement. So, there’s always the possibility the watch pulls away from the wrist, at least a little.

A coincidental video I watched recently, research on watch band type and colors, that mentions workout downsides. It can happen with any band, some just more prone than others.

During a run seems strange, unless you prefer to wear the watch looser.

My wrist doesn't get on well with the Apple Watch HR sensor, takes an age to lock on and often loses the signal. I've been using the Polar Verity sense band around my biceps which had worked much better.

Funny, I have the opposite problem. My Garmin Epix Pro 2 drops has dropouts fairly often. It especially struggles with interval workouts and when I ride out of the saddle on my bikes. Never happens with my AWU2 which one of the reasons I use it much more often than the Garmin.

I use the Polar Verity Sense also (if I remember to charge it) when I run with an AW.

Yeah, when I do rigorous trail running HR readings have gotten so unreliable for me that I now run with a chest strap HR monitor, which has been bulletproof.

 

[GeekyGrannie]

Same for me. No minor adjustment will fix it. If I stop and pause the app briefly and then resume, it picks up the HR again, only to lose it again later. I now suspect it has to with the software algorithm rather than the hardware sensor.

For me, it's seasonal. In the warmer months I rarely have an issue maintaining a heart rate reading during a workout, but once the mercury dips it becomes a lot more temperamental. Was a bigger issue on my series 5 than it is on my series 9, but happens on the newer watch too.

It is seasonal for me also which tells me that capillaries on the skin constrict to preserve body heat. The sensor depends on blood flow through these capillaries to output HR.
