[Bip] HR monitor is bad - Amazfit

So how's other people experience with the BIP's HR monitor.
I was expecting it to be not as good as chest straps.
but today i tried for the first time while doing intense exercise(squash).
So before i started when my HR was still low i started the indoor run activity, with the watch quite tight around my wrist.
During the sport sesj i looked at the screen many times and it never showed above ~105ish
so at some point i stopped an measured manually, and found a rate of >150
and this was continuous for 40 minutes.
I understand slight deviation but this is basically not even close.
I also tried to untighten it a bit and also tried it on the bottom of the hand. nothing really helped, i never saw it go above 110.
Any other's have better experience with high HR exercise?

Sadly I have same experience as you. It tends to show significantly lower HR rates during workouts. Only few times I was able to measure something above 150. Mostly when I am about 160bpm it shows only maximally 110 and sometimes even bellow 90! So my experience is that's it's good only to track sleep HR. Only those rates makes sense on BIP

amazfit pace very inaccurate heart rate sensor

So I bought the pace model.
Did an interval workout on the treadmill, after I checked the app it measured 195 heartbeats/second. Which was nice and well becase i know thats where I end up at the end of those 4 minutes.
However, after that I did some strength training, and then finished off with some uphill walk on the treadmill where the treadmill measued 150 BPS, and my watch... 88 BPS. I know 150 is more accurate because my breath was around there.
After that, it hasnt been able to register anything over 110 BPS. Tried it for several workout sessions, still doesnt measure above 110. I tried factory reset.. doesnt change anything.
Someone else seen this?
I'm testing one amazfit and comparing with one garmin 630.
Amazfit measures correct just after 10 minutes of workout and then, after some minutes it measures wrong about a minute or two, and back to measure correct again.
Very bad algorithm.
Has nothing to do with bad algorithm.
Why do you guys think that there is no gym workout on the watch?
Because there is no known wrist hr sensor that is working correct for that.
Doing workouts means bending and flexing the wrist, which means that the sensor looses contact, which means inaccuracy .
And 90% of people that complain, have the sensor on a spot that is not really working.
Have seen very hairy guys complaining or people that have the watch "between the hand and the bone".
And make sure it is tight.

Holy crap, 195 beats PER SECOND!!?!! How are you still alive? Are you The Flash? Or possibly some kind of super smart hummingbird with an xda account (that would be cool).
Jokes aside, I also find the HRM on the Pace problematic.
It seems to work ok when you do "check now" as long as you stay still and its on tight. But whenever I use continuous HRM or do an activity like biking the reading seems to be about 20+ bps too high.
For example, I did "check now" just before a bike ride and got 65bpm, then again right after the ride and got 104bpm, but the bike activity recorded a starting heart rate of 84bpm and an ending rate of 134bpm.
yeah, sometimes my watch seems to measure my heart rate correctly, but other times it shows quite strange results.
I just finished indoor cycling workout. I used together Suunto Ambit watch with HR strap and Amazfit Pace. Amazfit HR data is useless. Here is merged image with both graphs.
Amazfit was tight, and my hand didn't moved to much. I tried several times to move hand on different positions to check is there any improvement, but without change.
Here is paralel graph (top is Suunto, bottom is Amazfit)
sometimes when physical exertion increases (when I go up a slope, for example) the heart beats are reduced.
The HR sensor in the pace seems about as accurate as someone guessing your heart rate from across the room.
Yes the bip is the same.
Absolute ****.
I've compared it with Polar watch + chest strap. There were differencies in the meassured pulse, however the average pulse for the trainings was very close on both devices. What is important for Peace, it has to be fastened very tightly on the wrist.

I have compared Amazit Pace (1.3.6d) with Garmin Chest Strap HR monitor and FR235 doing Interval training running, and to FR235 optical HR monitior doing indoor biking.
In both activities Amazit Pace worked inestable the first 10 min then worked showing nearly same HR thank Strap HR and optical HR monitors.
Amazfit Pace showed a sudden decrease in HR reading about the middle of activities (about 1 hour each) and then back to proper reading.
In summary, Amazfit Pace uses about 10 min to have proper HR values, and sometimes during the activity has sudden decreases in HR reading.
For the rest of activity it performs quite well.
but you know that you can pair amazfit with a heart rate monitor strap, for example Polar H7?
This is about the Pace, and that can't be paired with a strap.

oh, ok, i was talking about Stratos
heart rate sensor go crazy
I have the pace model too
sometimes (recently with more frequency) the heart rate sensor go crazy
yesterday, when i did an Indoor Run, he show the alert: "heart rate too low: 75", seconds after this, he show: "heart rate too high: 185", seconds after: "heart rate too low: 81", "heart rate too high: 172", etc etc.
Someone else seen this?
Someone know how to fix it?

Is the watch brand new? Do you sweat a lot? Check the cover of the HR sensor, some people that had used the watch while bathing/showering had problem with the cover getting loose.

I bought my pace in Feb/18 (3 months ago)
my sweat is near to zero
never bath/shower using it
the pace work well until one week ago, when i need to do a factory reset because something was draining the battery too fast (one charge in one night)
after the reset, the battery issue has gone, and the watch work well until yesterday (when the HR sensor issue start)
thinking about do one more factory reset... :fingers-crossed:
just to illustrate: HR (red) x Cadence (blue)

Same issue here, with every Rom update HR accuracy gets worse in Sports activities. Continuous HR monitor seems accurate when compared to my chest strap, but goes haywire and at least 50% off true when in Run Indoor and Cycle indoor. Elliptical seems to be accurate at least some of the time. Have factory reset many times but nothing seems to help.
Yesterday I realized that with new ROM update, Peace have option to connect to other Bluetooth sensor(s).
I tested it and it with cheap 20$ Bluetooth sensor and works nice.

Is it possible to have a rom that does 1sec heart rate intervals?

My garmins have a 1hz update which = 1 second updates to the heart rate even when not in a workout.
My fitbits do 5 second updates.
The amazfit Stratos I have does 1 minute updates when not in a workout. This is too slow of an update interval.
I know the battery would be reduced but I don't care about that. Is it possible in a rom? Or any other way?
What do you want/need the data for? You can start Elliptical, it will record the HR as any other activity and you will have the HR graph.
Yes I know you can start an activity. That's not the point. A lot of watch faces show heart rate so why not have the watch face always up to date with the correct heart rate?
If I get up and walk down the hall at work, I shouldn't see a heart rate of 55, my other trackers have no problem having more frequent updates and they show my heart rate elevated if I get up and move around. Heck even the Garmin battery lasts 2 weeks without a charge at 1 second updates.
I can't be the only user that wants to see the heart rate in real time. If that's the case then they probably haven't tried other devices yet.
The continuous HR as is already cuts the battery by about a third of the average. An update of 1 sec would also degrade this. Now, the larger battery drain would be the screen updating every second with this HR data. Try a watchface with a second hand. It obliterates the battery.
The garmin and fitbit UI's are more refined and battery conservative. Not to mention garmin will last much longer without continuous HR. I doubt this will make it to amazfit software.

Multisport tracking: Swimming, hiking and skiing on Amazfit Stratos

I open this post because I haven't been able to find any review or opinion about one of the functionalities that offers Stratos: Skiing.
Has anyone try it and can share his or her experiencie?
I am interested mainly if it is able to dismiss the skilifts automatically on Alpine ski.
I assume it can measure speed, hear rate, and the other normal variables that are shared with running.
Any experience?
As well I am interested to know if for long multi-day hiking trips the battery would resist with the GPS active? (like 12hours sport tracking?)
In general, it would be good to know the tracking difference between one sports mode or the others
Last weekend I just made a long hike and starting with full battery and with GPS on of course, it recorded all my 11 hours hike. At the end, the battery was at 12%
I have just returned from a 400+km hike where I used the Stratos constantly. With an average of 7h of hiking I got 3 full days of battery life: Bluetooth on, sleep tracking but obviously internal HR sensor off during activities and outside.

What about the readings on altitude? Looks pretty inaccurate in the reviews and it's a very important metric when hiking.
Does anyone else have any feedback on the "Skiing" mode please? I am also interested in this mode, and whether it automatically detects travel on the ski lift. Thanks.
Stratos skiing mode
Just used my stratos for a couple of days skiing and am pretty disappointed in the results. Firstly the altitude readings are pretty inaccurate, out by more than 10% in some cases. Amizfit support responded with the following "The altitude error is greatly affected by the environment.
Due to environmental factors, the error may reach tens of meters or even hundreds of meters." So even though this is a metric that is important to skiing dosn't look like it can be improved.
Secondly, yes it looks like the watch does stop recording during lift travel and start again during a downhill run. This is what I noticed when I looked at my tracks. There was the odd lift travel that may have been a bit downhill that got recorded as a lap but most of the laps were actual runs. I even looked at my watch at the end of a run/lap and noticed that it recorded the downhill distance and descent for that lap. When I started riding the lift these results cleared and the watch was ready for the next run/lap. So this is were the good news stops. Even though I was under the impression that the watch was recording all this great individual lap information when I tried to see my results in the evening on my phone app most of my metrics were all combined into totals. For example total laps, total downhill km, total descent and total time. The only metrics listed per lap/run is max speed which is good and the time each lap ended, which is useless becuase it includeds lift waiting and riding time.
It is sad as I believe the watch has been designed and is capable of gathering detailed information but the phone apps inability to present this information totally ruins a potentialy good product. At the moment I would not recommend this watch for skiing. Go back to using your phone and any of several free ski tracking apps.
Many thanks for the detailed feedback. I used the Skiing mode on my Pace a few months ago and found it almost useless because it didn't detect travel on the skl iift and treated it as part of the ski run, thus totally ruining the data it collected.
So it meant I had to take my glove off to manually start and stop the Pace (since it doesn't have buttons like the Stratos), which of course means digging under the sleeve of your ski jacket and fleece, and then adjusting the clothes back. Doing this at the start and stop of every run is a big hassle when you're with a group of people. It's not worth it.
I don't think I checked the altitude accuracy, so I can't comment on that. I also couldn't work out how to use the 'lap' function. It treated every run I did as the first lap, even if it was a repeat run on the same slope.
Amazfit still doesn't seem to have any instructions for this mode.

Amazfit Bip Heart Rate Monitor Issues

My Bip’s heart rate monitor seems to be working fine when I am resting. I have detection frequency set for every 5 minutes. However, when I am working out, I am not getting anywhere close to an actual reading. The detection is updating frequently, which it is supposed to do when you’re increasing your intensity. However, the reading stays low even when it’s clear my heartbeat is well over 100. When I say low, I’m not exaggerating. Last night, the reading dipped into the 40s while I was working out. I couldn’t even come close to that while resting.
Additionally, once my workout was done, it actually gave me an accurate reading of a heart rate over 100. Just not during the workout. The app is also not showing that I was in an intensive state. Its very confusing.
Does anyone know how to troubleshoot the Bip to get an accurate HR reading while working out? This is one of the main reasons I bought the watch in the first place.
Thank you.
Same issue here..
To me It seems like the watch only gives more accurate values when my actual heartbeat is under 90-100..

Amazfit GTR heart rate problem

Hi guys,
I just got my new Amazfit GTR and noticed strange behavior of heart rate monitor. It shows values even if the device is not on my wrist. I left the device on the table for more than hour and any time I looked on main screen there was heart rate value and it was also changing the values. So it wasn't just last value stuck. I tried to run exercise activity while leaving device on the table and it was showing heart rate as well. Not all the time but sometimes there was value and sometimes not. So is the device faking heart rate values? Is it normal behavior?
It is how PPG sensors work, they use the reflected light to estimate the number of beats. Search the internet for more info.
Well, I have another watch with PPG sensor but they don't show nothing when they are not on wrist.
So it will probably not be about sensor type. In this case they for example report my rest heart rate during the night even if they lay next to me on the table so the values will be completely faked.
The sensor works that way, but other devices may use *other* sensors to disable the reading when they detect the watch isn't being used, the accelerometer for instance.

HEyy,
- Also got 2 other product with the same comportment `` Fitbit Charge Hr ´´ and `` Fitbit Blaze ´´ , both detect when they are not in the wrist. Why doen's GTR do the same?
- Also both got more accuracy in Heart rate measurments...Because they are doing it consistently. With Amazfit GTR i only can program it to do it 1min in 1min. Already change it with Notify & Fitness. nothing seems to change....
- Another outburst from my side : heart rate scale doen't save scores higher than 180 BTM !
Are some of them just software issues ?
Regards to all
The heart beat sensor on the GTR is utter garbage. It does indeed fake heart beat results. Also the sleep analysis functionality is totally broken.
Just got my GTR and the heart rate monitoring is way off. Always some 20 to 35 Beats above the real one. As I have some hair I tried it in my finger and in my belly with the same wrong results. The firmware version is 1.3.4.19 which was updated immediately after first turn on. In contrast the free Android app I use is pretty accurate. I will still test the GPS.

I returned the GTR and got another one from another vendor and it has the same problem. I can now say that the heart rate monitoring in the GTR is useless, just a boring toy.
Amazfit admits that the heart rate monitor is "prone to inaccuracies" in its faq: https://support.amazfit.com/us/faq/839
As the heart rate sensor is basically a pulse oximeter which monitors the perfusion of blood to the dermis, it’s prone to inaccuracies.That’s because skin perfusion — a measure of how much blood flows through your skin-varies significantly from person to another. Especially the ones who have dark skin, hairy wrists, tattoo, and scar.

Oddly enough I have found the heart rate monitor to be remakably accurate if worn correctly and over the range 60-110. A few moments ago I confirmed previous results and while the watch showed 91 bpm a simultaneous ECG showed 90 bpm. The problem I have with the HR monitor is that it seems, when the cpu is stressed, to produce crazy results. To get around this I run exercise from the phone and get sensible results from the HR monitor. I might add that I was cooling down after exercise!
Well seems I am testing today. Had the watch about 2 days. I am guessing the watch does NOT show the current temperature? Like that matters. The GPS took about 45-60 seconds to connect, as others had. Seem to do faster NOT on wrist. Now my heart-rate monitor works really good. Tested it and I when I got 86 the watch got 85. did it again I got 84 thee watch got 85. Now I did take it off put it on the rubber mat and it kept going up to about 96 lol Put on my keyboard( light on top of keys) it went down to 40. Yet on my wrist works really good.
