I've recently received my Amazfit Stratos and I was worried about the GPS performance. I took a run with both the Stratos and my Garmin Forerunner 235 with this results:
(Amazfit data in red and Garmin data in blue)
GPS fix takes longer in the Amazfit (about 25-20 secs more)
Overall, both give a similar total length (Amafit 10.47 Km vs Garmin 10.46)

It seems that at the start Amazfit had a big gap in the position:

But it gets corrected and they follow very similar path. I would say even that Amazfit takes a more precise GPS measures or in a shorter interval since the curve is less edgy:

Although it is not perfect and Garmin seems to have a slightly better GPS, I would say the Amazfit GPS is good enough for my needs.
Does the Stratos have different GPS modes? Usually in Garmin or other sports watches one can set the GPS interval for more or less accurate values / battery life. Also is there a smart mode which is just polling GPS like every minute and then estimating the values in between using the accelerometer? Is Glonas supported?
Theres no GPS modes in settings...

OMG, it's drama. Starting to regret that I've already ordered For me, in term of GPS quality, Garmin (Fenix family to be precise) was a total sh*t comparing to Polar V800, wchich gives outstanding recorded track precision. But now I can see that Amazfit 2 is even worst then Garmin...:/
I just checked out the FAQ on amazfitcentral and saw that battery life time with GPS is 35h. So it must be some similar to smart GPS mode, means GPS intervall is low and the gaps in between are filled with help of accelorameter.

Maybe this is the reason. If yes - hope that some update will give a choice - for example 1s, 30s, 60s sampling.

Don't only read half of the information, because then you get the wrong impressions.
They have a new Sony chip ( 28nm ) that needs only a fraction of the energy that the others need.
Nice test, thx.
It would be great if someone compared Pace vs Stratos.
I love my AMAZFIT Stratos. Uses it daily for one year now. During my last holidays i took it for a swim to openwater (sea) - as it is marketed as water resistent.
Some days after that the swimming the Stratos seems to turn of randomly. When it is the battery is draining in the instant. I can literally see the battery go down in 1% steps.
I read that the AMZAFIT Pace can be damaged by seawater as it is only IP67. Is the same thing true for the Stratos? Any way to diagnose my Stratos further or is it simply broken?

I've been to snorkling in the sea just the week before and found no harm to the watch. Looks like a faulty device. RMA it
Battery drain
Hi, I have exact same problem, which started 2 weeks ago. Eventually I left it charging for longer time and it seemed to be solved. But problem is now back.
Hope someone in this forum can help us. Tks.
Replaced the Strato with the GTS and the Pace (only for Running)

Hi,
I have a Stratos 3 and was expecting a better GPS Accuracy.
Have recently updated it to 4.2.2.1 and it improved but it still takes take some time to lock signal.
Also, after a few experiences, I have noticed that if you start the activity immediately after locking signal the first few minutes will be inaccurate and it is better to wait a few minutes.
Any experiences from anyone else?
What pair are you using?

Same here - I had the first Stratos and finding GPS signal was quite a bit faster than on the new one. Hope they'll do something to improve it. Though, considering what have they done with the Amazfit app, I'm not very optimistic...

I have tried GPS + GLONASS and GPS + Galileu so far.
Galileu was accurate after the first 5 minutes only.
i'm expecting the same with my Stratos 3: GPS+ Galileo if start activity immediatly after GPS Fix it needs some minutes more to be accruate (5 min) but after it's perfect (i'm cycling in forest)
I did not try GPS+GLONASS for the moment will do it next time to see if it's better for initial fix and if tracking accruacy is as good as GALILEO
Gps and heart sensor
Hi, I sold my gtr because gps didnt work, I thinking I a Stratos 3, What Is it The heart sensor accuracy?

the HR sensor is exactly the same so you know it!
Tks for reply... I think that we need to considering the sw factor as well....
Sad to hear that, I'm using a Pace and thought Stratos 3 as a improvement over GPS accuracy and Heart rate.
Pace is a mixed bag, sometimes it's very good but, even in open areas, sometimes the accuracy show my position on the other side of the street.
Often I experience inaccurate position on the first minutes also.
Let's hope for a software update to increase reliability.
Stratos 3 uses the new HR sensor used in both Verge and GTR/GTS, so it should behave the same. It's a bit bigger and should work better than the ones from Pace and the original Stratos, as it does if I compare my Verge with them. Just don't expect it to be perfect, as any other PPG (optical) sensor.
The same issue with Pace and Stratos (v1). You should always wait 2-5 minutes at the green Go screen before starting activity recording. Also, with Pace, I used to run with Airplane mode for better accuracy, but it looks like in current versions it makes no difference (better accuracy in both cases than early). That way you can avoid GPS inaccuracy. My Stratos 3 is on the way.
Are you on latest firmware? I had mine for a week and updated it the first day. GPS is very good and fixes fast (I returned the GTR because of the GPS being so bad). Maybe your issue could be location related? Like AGPS data related?
@Paxy
Weird. I'm a new Stratos 3 user.
I have no accuracy issue with the GPS (Glonass) and the fix is done in less than 30 sec. Unlike the GTR, I sent back whose GPS was a deep sh.t.
I made 8 cycle workout and it worked very well. I leave near Paris there is buildings (not too high) around me during my
sessions and the recorded track is very good.

Can you, please, post an example, I'm thinking on ditching the GTR and considering a Stratos 3(which should actually be 2, because the first one was called Pace)?
Thanks!

Hi here is 2 run one with GTR and one with Stratos, there is NO comparison.
In orange, the trace recorded by both watch and under you'll find the covered distance which totally approximate on the GTR as most of the run was not receorded.

Thanks for taking the time to post these.
Seems pretty accurate. Have you checked through google maps to see if the distance is accurate? Is this the route: https://www.google.ro/maps/dir/48.8...0x47e67b314410fbbb:0x21dd71e67173a3e0!1m0!3e1 ?
@winni21 That's how my GTR cuts corners as well. Stratos 3 seems very good.
Now I'm pretty sure the GTR has faulty hardware for GPS (frame used as shared antenna with bluetooth), since they both have the same gps chipset and will never get fixed through software update.

Compared to Google Maps, the given distance by the Stratos is pretty accurate as I have 9.53km for stratos and 9.6 for GMAPS.
But on my road I have to go in a tunnel for few meters and the GPS signal is lost at this time. On this section the Stratos show a straight line and google map a nice curve. The curve is around 200m, so this part explain partially the 70m missing on the Stratos.

You are wrong. There is the Pace and there is Stratos (in China called SportWatch 2). There is no Stratos2 and Pace is not Stratos1.
My Stratos3 just arrived. It has fast GPS fix, but haven't tested accuracy yet.
I will compare it's accuracy against Pace soon.
BTW. Huami declares only Pace, Stratos and Stratos3 as sport watches. GTR,GTS,Verge etc are just smart watches without GPS in the focus of development.
There is also Stratos+ on Amazfit official web. The problem with the naming comes from resellers giving different names like Startos 2S or Pace 2.
But indeed there are 3 generations of the Amazfit Sports watch (Pace, Stratos/Stratos+ and Startos 3)
Hi guys. To the ones Who have the stratos 3,cab you tell how is the battery behaviour with external Bluetooth chest strap paired?
In stratos 2,it is awful
Unfortunately I have not managed to get it working with the polar H7 strap (I had read that the H7 worked fine with the Stratos 2). I tried to connect from the workouts setting in the accessories, it paired but but it doesn't connect...
Regarding battery life in general I had mine for 5 days and it is almost empty (it had 85% when arrived) Didn't use it very much and I turned GPS on max 45min. So it feels not much better than Stratos 2, let's hope it will improve with future updates

I have stratos 2 and I'm thinking about buying the stratos 3. However, my major doubt is the weak improvement in battery performance.
I had a Pace which died after I forgot it on at the Swimming pool. The Stratos 3 is much better in many ways. But if your Stratos 2 still works fine I honestly don't really see much upgrade

that's what I´m afraid of... The little increased battery capacity (290mAh to 300mAh) and my doubts about the consumption management when paired to an external bluetooth chest strap make me see it like a bad upgrade.
Maybe a "Stratos 4" will answer my expectations
I tried again and this time it connected to the Polar H7 strap. I only made a fast test (going for a 5min walk) but it seems that the battery consumption increases a lot with Bluetooth accesories. It went 8-9% down in 5 min.
I will update you when I do a proper workout but it seems that didn't change much from 2 to 3

thank you. In fact, that is a lot...
Here an update on this. I have been using it more regularly and the battery consumption has become very good. I get about 7 days of regular usage (including a couple of workouts using gps and external hrm). If I don't do any sports the battery life goes to 10+ days
Hello,
new product came out, and that is Amazfit GTS 2. Anyone already have the watch? Can 1 week battery life still be achieved if all features are turned on?
Thank you for the answers, I really appreciate it.

This guy is a long term supporter of GTS and GTS2. He praised a lot for the old GTS and its amazing battery
But in his review of GTS2, after using for 10 ten days, he said the battery is really PATHETIC, only last like 2 days.

I saw this video but this is the only one that is saying the battery life is 2 days...so I'm looking for more users that can verify this before I buy it...
Thank you anyway
I found two more review on battery test for you.
https://www.igeekphone.com/amazfit-gtr-2-in-depth-review-2/
In terms of battery life, according to the official statement, Huami Amazfit GTS 2 has a battery life of up to 7 days in daily use mode. I turned on the active heart rate detection + sleep assisted detection mode, turned on the sleep breathing quality test, and used the watch according to my own habits. The power consumption was 29% for 28 hours and 12 minutes, and the battery life was about four days. If you follow the official daily use mode instructions, the battery life will be further extended, and 7 days does not seem to be a problem.
https://www.androidcentral.com/amazfit-gts-2-and-gtr-2-review
What's honestly most impressive of all is that the developer's battery estimates for these smartwatches don't appear to be overblown, a rare thing for smartwatches or tech in general. After a week of use, including using the always-on feature sporadically, tracking my sleep cycles, and going for several workouts with GPS activated, the battery only recently dropped below 50%. Keep in mind that it would drain faster if I had continuous heart rate / SPO2 tracking enabled, but for most users, the GTR 2 could easily last you up to two weeks per charge. For comparison, the GTS 2 has a 7-day battery estimate.
Hope it helps, bro.
Personally, i'm using GTS and see no reason for the upgrade to GTS2. If you haven't bought GTS before, then maybe it's worth it.

Ya ta solucionado.
I have the gts2. I've had it about a week. Battery with usual use is about 4 days. I have wrist flip detection on high and get about 3 days. Overall I really like the watch. Waiting for Alexa update to come in the future.
I have the GTS 2 since the day it launched in India. Love everything about the watch except battery life.
Battery drain is too much. Hardly getting 2 days. I find it absurd to first purchase smartwatch for its features and then keeping most of them off to get battery life.
It is possible to turn WiFi off and bluetooth on?
Hello, I have it and only two days of battery life. I have a week with him and the clock is not bad at all. Taking advantage of the thread, you know how I can activate the extra functions of the watch.
I bought a few days ago GTR 2, and all is almost perfect except for the battery... firstly from 48% to 10% within 24h, . After fully charged, 3 days and 50% has gonewith one, 1h training per day without GPS.
I like multitasking, wifi (fast watch faces synchro), but AOD drains battery a lot I decided to disable AOD, sleep tracking, switched heart rate to 10min. interval and after 24h battery decreased from 56% to 44%, while I know that people with GTR 1 have 1% per day with almost the same settings...
so I'm really disappointed with such battery life...
Do you have any advices?
@Redmundek, my girlfriend has the same problem. I bought GTS2 for her and GTR2 for me and with the same settings I get ±10 days of battery life and she gets ±3! Did you find any solution?
Have you checked the settings for detection method? Try different option and see:
- automatic heart detection - for me it is Ok
- Sleep assistant - may be the root of possible more draining
- Automatic heart detection & sleep assistant - potentialy draining battery a lot (as far as I remember)
Then other options below: activity detection, heart rate alert, all-day stress monitoring, sleep breathing quality.. I have ticked most of them after different tests. No issue with battery draining (I guess)
I'm using a GTR2 but I remember having seen a big change in the battery draining here when I tested different settings.
Good luck.
Hi, I amended sleep monitoring and stress detection and the battery is quite good, even with AOD from 7:00 till 22:00 (which I prefer) it can works c.a. 5-6 days
