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.
Hi all,
as the name says - how is your experience with swimming with Amazfit Stratos?
Stratos looks great - but looks is not all that matters.
Regards
Hi!
I'm also very interested in swimming mode!
So far I found only a very detailed faq.
I'm not allowed to post url, so you may search amazfit 2 faq on Google.
It should bring you to amazfitcentral.com faq for amazfit 2.
See §85.
It gives information about what we should expect from swimming mode.
Despite this I found no reviews of sports functions.
So many unboxing videos, showing the box...( Seriously? Who choose a watch because of the box??), all videos shows similar stuffs, but no details about sports modes
I just know that the screen will turn off in water. The FAQ only says that in swimming mode one has to set rows manually. I do not think HR, GPS or even strokes will work in water. Anyway is there a general sports program for doing workouts? The training features is really a thing what is making me interessted in this watch. Firstbeats training load, recovery time advisor and so on, one can only find in really expensive Garmin watches or similar in the Polar M430. The cons is the size. I guess it is 50mm in diameter which is huge. Mostly too huge for 24/7. Also I don't know if I would trust Chinese in sports. They never do sports. Trust me I lived there.
All the so called reviews are just made by some silly guys never really used the watch. Doing it just for the kickback of some chinese store. Not trustworthy.
Hi!
As far as I have seen, the screen does not turn off in water.
There are some videos showing the watch in water (not a pool, just some kind of large glass, not sure of english word for that).
Only the touchscreen is disabled and it's not surprising. You can use the buttons instead of touchscreen to navigate while in water. I guess that's why there are buttons.
Regarding the FAQ, it says much more than set the row manually, copy paste:
85. Swimming function
Watch support swimming pool and open water swimming two modes.
Swim terminology
Lane Length: The length of your swimming pool. The watch will calculate the swimming data based on the lane length you set.
Set the corresponding lane length for each pool change so that the watch can accurately evaluate your swimming data.
Trip: Swim in swimming pool swimming pool length of a lane.
Paddling: wearing a watch for a complete paddling action.
Paddling rate: the number of paddles per minute.
DPS: Complete a full stroke of the water.
SWOLF: SWOLF is an important indicator of swimming scores, which is equivalent to your comprehensive evaluation of swimming speed. SWOLF for pool swimming mode = single trip (in seconds) + number of single trips. SWOLF in open water swimming mode is calculated as 100 meters. The smaller the number, the better the efficiency of swimming.
86. Swimming recognition
The watch will recognize the swimmer’s posture in swimming mode.
Freestyle swimming
breaststroke
Backstroke
Butterfly stroke
mixing
87. Touch screen in swimming
To prevent misunderstanding and water interference with the touch screen, the watch will be closed after the start of the touch screen touch function. At this point through the watch button motion control, after the end of the watch will restart the touch screen function.
Regarding HR and GPS in water, no idea....
-as far as I know, GPS is not good underwater and in a pool, it's much more accurate to count lenghts than GPS.
-HR: I heard some works in water (with reduced accuracy), no idea for the amazfit 2, that's why I wait so much for a swimming pool review .
Regarding the so called review... well I agree, and they are not really "review", only unboxing and show a couple of stuff (very very little)...there are maybe 100 videos like this, all showing the same. Those guys drive me mad: This watch has a very new feature compare to amazfit pace: this 50m resist + swimming mode... and they do videos with 20sec reviewing...the box, nothing on sports modes
Thank you for the information. I meant touch turning off in water, which is actually a good thing.
The Chinese version 2.0.8 in the pool is very bad.
English version 2.0.7.5 from Nicola Sagliano works in the pool super! Correctly considers the number of swimming pools that I swam, time, calories, swimming style and other parameters. In the water, only the buttons work. The screen works in this mode constantly.
GPS in the indoor pool does not work. For open water there is a separate regime. His name was

Hi, I took my Stratos at pool swimming 8 times and result is> I am not very satisfied with watches.
Swim.
1. Firmware 2.0.8.0 tries to round up meters and pools. That is logical because It is a way you usually swim at pool.
2. Firmware 2.0.7.5 does not round up pools and meters at pool mode.. It does. The last pool is added when saving or resuming session.
3. Both firmwares have problem with first pool (graph of pace and trash starts around zero (= nonsense) and complicates graph reading because Y axis is then not very detailed at the point of interest)
4. Firmware 2.0.8.0 can correctly count last pool. With 2.0.7.5 you must start at least one more pool to count the last one. It does. The last pool is added when saving or resuming session.
5. The measuring one time crashed when saving data with notice that sport application crashed. The session was not recovered and all measured data was lost (very bad coding of Xiaomi team).
6. Watches does not measure kicked pools. (Pools swim without hands). That is normal.
7. Due to inaccuracy of measured pool counts and problematic first pool are counted trash and pace values only informational.
8. It is unable to edit measured data so you cannot add kicked pools or correct bad readings.
At pool mode does not work GPS and heart rate sensor. That is normal.
Run (Firmware 2.0.7.5).
1. Very inaccurate GPS readings when run around 8 stories buildings.
2. Due to point 1 the measured distance differs from measured at Google maps about 10 % (3.1 km instead 3.4 km).
3. Due to point 3 all calculated values dependent on distance are nonsenses (speed, kCals, strides, TE, VO2max, EPOC).
Notices.:
Watches CPU is really weak and that causes problems with application starts (e.g. swimming) or lags when scrolling or screen listing. It is not so bad as described.
Coding of sports applications is really bad. When application crashes all data are gone. Sports application does not make recovery saves (at least swimming).
Watches e.g. do not sum counted steps after factory reset etc. Watches saves only higher value from measured before or after factory reset.
There is a bad sync between watches and phone app. Watches shows different sum mileage from phone app after crash of sport app at watches.
You cannot add or correct measured data, that leads to e.g. watches counts only 26 50m pools and do not calculates 14 kicked pools and that results in very low training load.
Tom
Thank you for sharing your experiences!
8 story high buildings are always a big problem without GLONASS. I guess Stratos doesn't have GLONASS.
Hopefully the crashes will be fixed on final firmware.
I agree it is a must that workouts can be edited in the companion app and then synced back to the watch. Cannot be so difficult to implement.

I have read a few weeks ago a review of several watch for swimming (not the amazfit 2).
It was suggested that pool lenght counting is based on 2 things to be catched by sensors:
- "shock" detection when hitting the wall.
- "pushing" when going back to other direction.
So for accurate count of last lenght, it was recommanded to make sure to "hit" the wall correctly with the arm that has the watch. and also to start a "last push" back on the wall, like for starting a new lenght (and then you can stop).
Not very natural but....
It was also a good idea to make sure to hit the wall with the hand with watch and make a good push at every lenghts to improve reliable counting.

Some HR sensor does work (more or less accurate)...so I'm not sure it's "normal" even if it's also common that many HR sensors does not work in water.
I have a stratos, I have been swimming 2 times with bass and the length counts very well, you do not have to bounce the hand on which the watch is. The screen is always on and locked, buttons are working.

Hi.
1. Look at the attached picture. Thrash speed starts with zero and every time you pause session trash speed drops to 0. This is problem for calculated average trash speed because is lower than real average one. At the pace graph is a problem with one speed drop (I paused session about 2 sec after finishing pool). This made a great speed drop and Y axis is than not very detailed at the point of interest. Y axis should be from 2 mins to 1 min 14 sec. That speed drop should be cut out. I think that first sec of swimming should be cut out.
2. Pool counting. I made some test and I must say that watches count pools correctly. The last pool is added when session is saved or immediately after session resume on 2.0.7.5 firmware.
Example: After finishing 20th pool and pausing session watches shows only 19 pools. When session is saved (ended) or resumed pool counts is corrected to 20.
3. Kicked pool.... I meant pool that was swimmed without hands only with kicking legs.
4. -
5. I think that is normal that HR optical sensor does not work at pool. I think that Garmin Fenix also does not measure HR when swimming.
Hi, thanks again for added information! :good:
3- ahhh I see . Sorry I can more or less speak general English but don't have the "technical" words around swimming.
I also just noticed it's "thrash" and not "trash" which was confusing
5- I have seen on a suunto page "ACCURACY OF WRIST-BASED HEART RATE MEASUREMENT" :they write " The optical sensor may not provide accurate heart rate readings for swimming activities."
So to me they mean it may work but not accurate..
Also a couple of sources told me that the apple watch can do it.
So I guess it depends on watch....
I also read some watch just disable it while swimming (to avoid showing inconsistent data)
How do you do gym training? I cannot find any sports profile for it.
Hi,
Check the faq on amazfitcentral.com, it's a mine of information!
Sports mode are jogging, running, walking, cross country running, indoor running, outdoor riding, indoor riding, elliptical machines, mountaineering, swimming in the swimming pool, open water swimming, triathlon.
I cannot post links for the moment (noob on xda), but you can Google it.

I already checked this out. But still there is no cardio, gym training or yoga profile. I do not need rep counting nor weight plans. Just time and pulse. I guess elliptical is counting steps. I mean ppl who are doing running, cycling or swimming are doing gym, training as well as part or their training plan. It must be possible to track this exercises.
Anyone who test diving into the pool or sea ,not over 10 M.
I want to know it that can measure the distance or not.
Thank in advance.

Elliptical and indoor cycling do not count steps, only time, heart rate and calories (based on heart rate). For gym, you can use any of these.

Hello. Can a swimmer that has stratos make a list of all the parameters that are measured during the swimming training?
Hi there!
I have a question, English is not my mother language and I 'm not sure of exact meaning of what the watch reports.
Does anybody could explain me the meaning of : pace, stroke, DPS and trips (as measured by the watch).
By the way, just received it, I may have a chance to swim with it next Friday.
Hello Everybody,
So after a lot of reading, it looks like this wonderful Amazfit Stratos could perfectly matches with all my new hopes and finaly
substitute for a perfect relation equipement/price ;my old school Suunto X6)
Though, there is often a "but",
I'm pretty sure this special use could interest a lot of people in specific outdoor activities, and hope we will find a way
So
I'm skydiver and would like use the watch at least under canopy for landing. (I doubt about the speed refresh while freefall, but not the matter)
Means I need calibrate manualy the altimeter on 0 (zero) before going in the plane, and landing safely after the jump on same altitude I had calibrate just before
Means probably too, the altimeter should works imperatively on just barometric data...?
Is there a solution to reach my goal? even if I should try to tamper the firmware or kind of push a special room??
Any idea is welcome))
Anyway sorry for my unperfect english
I was planning to build an apk that could do it. Because I also need it for paragliding.
Like configure current air pressure at sea level.
Calculate the current hight based on the air pressure etc.
I know the app GreatFit https://forum.xda-developers.com/smartwatch/amazfit/app-watchface-greatfit-v1-1-settings-t3791516 has the option to show your hight on the watch face.
I would be extremely wary of this. My Pace barometer is pretty accurate but the altitude isn't. I live by the sea so I have the perfect opportunity to test it. There is no way to zero or calibrate.
Interesting.
I was also planning to create an app for this, then I realized where the heck I could get the current temperature from. My pace doesn't have a thermometer, does it?
I am no expert here, but I think we need the pressure AND the temperature to accurately calculate the altitude. The altitude reading from the watch can't be accurate if the temperature isn't taken into account or perhaps the watch just gets the altitude from GPS.
thx for your answers
Anox, for what use do you wish realize this app?
So
I'm pretty sure I had read about the Stratos the altitude is linked to the GPS( after searching again, of course impossible to find
again the intel)
Effectively, On the Suunto X6 there exists also a temperature probe; I don't know if it use it to manage the altitude simultanously with the barometer
Then, looks like could be more simple to build an app than modify totaly a ROM)) that's already good news
How many times it could takes to build this kind of app?
The stratos and pace have barometer sensor, maybe it could be enough to make a try?
(i need specify with Suunto X6, by day I often have 5/10 meters of variation, I could reset and calibrate on the ground, or not,
15/20 sometimes, 30 meters when weather changes totaly though in this case we stop jumping)
I guess isn't either a problem for Istaveren while paragliding, 5 to 20 meters could be corrected by vision and experience?
Finaly

"Running mode uses GPS for altitude. trial run mode uses the barometer for altitude"

This rumor is quite persistent but was never proven and I'm quite sure it is wrong. From my experience with the pace it seems, that every activity with altitude measurement is starting by using the altitude from the GPS to calibrate and later on some mix of GPS and barometer to measure the changes in altitude. To realize this one must use the data from the pace directly since as soon as the data is processed in the phone app, altitude data is corrected on the base of an online altitude/shape map.

So, with what we have as data;

simply "WoNdErFuL" thank you very much for your precious time
I bought an Amazfit Stratos few days ago. GPS positioning is perfect but altitude/altimeter totally wrong and unstable. If I go to compass widget and wait for calibration I see tham gps the coordinates and pressure value are stables but altitude is changing between +-200m all the time. Watch's firmware is 2.3.7.0. Any idea?
What kind of activity are you using? Some use GPS while others use the barometer/altimeter. To reset sensors, turn OFF watch for around 15s (restarting IS NOT enough).
I see that problem for example in the compass widget

That altitude reading is from the GPS. So, the accuracy depends totally on the GPS which I find not very accurate.
The altitude calculated from the barometer isn't that accurate either.
Edit: This is not specific to Pace/Stratos. The altitude calculated using GPS/pressure, in general, is not that accurate.

My old Suunto was very accurate & barometric should be if it is reset to local pressure. But the Pace is totally inaccurate - I often walk by the sea & get wildly different readings.

GPS Altitude
A device with a better GPS chip would obviously be more accurate than one with a low-cost GPS chip.
What I'm saying here is that in general the accuracy of the GPS altitude reading depends on many factors such as the satellite configurations, signal blockage, and atmospheric conditions. The vertical error is much more than the horizontal error. Even Garmin says it is not uncommon for GPS heights to be off by +/- 400 ft.
https://support.garmin.com/en-GB/?faq=QPc5x3ZFUv1QyoxITW2vZ6&searchType=noProduct
Pressure Altitude
Local pressure with known altitude surely makes the pressure altitude calculation better. Even with that, to get an accurate altitude difference between 2 locations, both measurements must be performed at the same time and hoping the weather (air density, temperature, etc) doesn't go wild at the 2 locations. That's why I say pressure altitude isn't that accurate.
With all that being said, from my initial testing using my Pace, it seems pressure altitude is more accurate than GPS altitude and I'm planning to create an app for the watch to show pressure altitude with reference point calibration. Hopefully, it's more accurate than what is available on the watch now.
The altitude is wrong but the barometric is accurate

Many thanks
I bought Amazfit Bip two days ago, but barometer is only showing very low hPa (948.3-951.5) although the weather is clear and sunny (30 Celsius), is this normal or is this sensor defective?
Thank you for your help!

I have the same problem. Were you able to resolve this?
Did you check if it measures differences in air pressure correctly? Sometimes the body heat from your wrist can throw off the sensor as well.
I've noticed that the baseline elevation stats on my unit are off by around 30 meters, but the relative elevation stats are usually accurate.
Ideally there should be an option for manual recalibration but I doubt that Amazfit will ever add such feature, especially now when the device is already a few years old.
Your barometer is just fine. I had the same issue ( which was infact not an issue).

I always wondered what would happen at Panama Canal. Which side would be sea level.
