Stratos reboots during running activity - Amazfit

Does anybody have a problem with unexpected Stratos reboots during running activity? I lost many running logs because of that. This problem does not depend on battery capacity or lenght of activity. I already tried factory reset.

Disable all alerts in activity settings besides lap and HR (if you use them), also disable auto-pause if it is enabled as well as "Activity reminders" in main watch settings.
If it doesn't help, then factory reset but do NOT restore old data to watch and configure as above, then you can try to enable the settings you use one by one to find the culprit.

Stratos Unreliable Firmware
The nice ist that it happens rarely during long runs (>30km) but also during halfmarathons..
I like the watch, it works in most cases but we have to accept that it is not the proper watch class for serious athletes.
There are also few unresolved bugs in firmware... I think they are not able to fix it.
Just check your run cadence measurement.. it is a shame as it works..
I ran 80 - 90 km per week in last 2 years with Stratos and I have to factory reset it every 2 months+ restart once upon charging than it works fine.

Amazfit 2 Stratos battery issues - suspect software bug - reset daily helps

Hi, i have a new Amazfit 2 Stratos with official international firmware US FW (2.3.2.7) and noticed cases where the battery would rapidly drain within hours, for example I would go to sleep with 60% battery and 6-7 hours later it would be on 5%...
I then noticed that if i reset the device, the rapid battery drain would stop, for example i noticed a rapid drain of 10 % an hour, so i reset the device and it stopped draining the battery...
Which made me think there is a stuck process or some firmware issue that keeps draining the battery, and I now reset my device every morning which makes it lasts days.
Anyone else noticing battery drain issues?
Having the same issue. What watch face are you using? I'm trying to narrow down the issue.
I've noticed the same after converting from Chinese to US. I'm thinking it might be caused by WiFi (or something using it) as it didn't start happening until I added my network.
...
try to install Task Manager and you can kill some processes which are maybe draining your battery. I use it as i have plenty of apps there.
I found the cause - the data sync. Each time you access the app on your phone, it syncs the data.
When you disable the wifi/data connection on your cell and access the app (while watch is paired), it tries to sync and fails. Problem is that it seems to be stuck in a loop until data connection is available and by then the battery depletes rapidly.
Solution - don't access the app while there is no connection in your phone to wifi/data.
Not sure if this is the only case when the watch syncs data - it might be syncing it automatically each day at a specific time - will post more info if i find out.
I also don't know if this bug is caused by the new firmware or not because i received the watch only last week and immediately updated to the new version based on the notification in the app.
It seems there is also a difference in battery use when using different watch faces. For example, I've observed that a watch face with no temperature will consume less battery than with a watch face with a temperature reading.
Anyone with similar experience?
I've bought an Amazfit Pace that sufered from same issue, te battery starts to drain all the way down in a couple of hours, so i returned it and decided to buy the Stratos, and guess what?
I have exact the same issue.
Tryed some things and i think the cause is related with smartphone bluetooth, in my case OnePlus 5T bluetooth.
If i desconnect smartphone bluethoot it stops draining, if i put it on again it starts draining again, if restart smartphone it stays good until it happen again next day or so.
Problem with battery discharge Amazfit 2
Hi, I also have a battery discharge problem. The watch battery will start to discharge quickly when I turn on the amazfit application on my phone. When the phone is restarted and I do not go to the Amazfit application, the watch connects everything works and the flashlight is ok, I turn on the application amazfit and the torch goes down. Tonight I put the plane on the phone and plugged in only the bluetooth and my watch was discharged in the morning. The red bar at the bottom of the amazfit app only appears when I'm not connected to the internet, I'm connected all the time. I have amazfit 2 China, recorded by Rom 2.0.14.0, Amazfit Watch 3.0.0 and HUAWEI Mate 10 lite
So it has exactly the same bug as the first one... (and I have it on my wrist). Well time to go back to regular (but expensive for nothing) watches

Basically what usually cause these problems are wither data sync issues or a problem with Bluetooth/WiFi.

I noticed the same issue with my pace on my OP5 after à phone update. Tried to reset, pair un pair still the same.
Issue was removed after oxygenos 5.1.0 but immediately back after last oxos 5.1.1
To move on I paires the watch to my xiaomi mi5 on global stable rom Android 7, all is fine.
Seems many phones are bt broken with oreo.

I think too, that this is some sync related issue. If I check the watch data in the Amazfit app, then the watch starts to drain with 2-3% per hour. However if I exit the app and turn off Bluetooth on the phone till the notification icon and the watch show disconnected and then turn back BT to get the watch connected again, the battery consumption goes back to normal.
Opening the app again starts the battery drain issue again.
I wrote it already in another thread here, I own an Amazfit Pace, of course with battery drain issues. So I tested a bit. When the phoneapp is syncing it shows an information field at the bottom, this field becomes green when finished. But a few seconds later another datasync is made, not shown in the app but indicated by network speedmeter in androids statusbar. I think weather is syncing there but if you aren't aware of this and close the phoneapp before this second sync is finished, the watch runs into battery drain.
Since I wait 10 seconds after the app shows the green sync complete field I never had drain issues again.

I have the opposite problem. My phone battery drains like crazy. I have the Stratos for 2 days /int. version/. It works great, battery life is excellent. I suspect the Amazfit Watch App /Android/ is the culprit. I have to charge my phone 2-3 times daily??!
I think my Stratos worked fine until I activated the 'continuous HR' feature (and switched it off again). Before that, it would easily last for 5 days on a full charge. But I also get these fast drains now.
I restarted the watch a couple of times, let's see if this did it.
I've had the same issue a while ago (also after testing the continuous HR feature), and there I really had to reset the watch and reboot 3 times to get it back to normal again.

Something is breaking the Bluetooth connection between phone and watch, the most common cases are WiFi interferences (test with phone in Airplane mode and only BT on and see if battery usage is OK on phone) or corrupted data when syncing to the cloud (open Amazfit app and check if syncing is OK - you should see a green bar at the bottom -, you may need to unpair - it will delete all data on watch - then pair again and answer NO when it asks to restore old data).
Indeed seems bt is corrupted. When draining occurs, even if I switch off the bt from the phone, the icon on the watch says it is still connected. Again for me this does not occur on nougat, only when pairing with oreo device.

Did you find a solution or did you send back the watch ?
so until how do not know what is the culprit?
mine one can last one day......

[Bug?] Stratos can't connect to the iOS app, but receives messenger notifications.

I have tried to factory reset the watch many times, and everytime it will fix it, but after a few days, same issue persists.
Sometimes it will receive app notifications, sometimes it can't even do that.
**Right now it shows in my bluetooth settings that the watch is connected(probly why Im getting notifications) . But again, no connection in app**.
Very frustrating as I won't be able to view any of my stats on the app at all.
Anyone else experiencing this?
Since no one replied...
UPDATE:
I gave up on the iOS app, seems like it's just a persisting problem right now.
I managed to not lose any data by enabling the hidden app list, and paired my watch with my Samsung phone instead. So I didn't have to factory reset it.
And the Android app so far is working much better. i.e. Custom watch faces actually shows up in the app.
Make sure you have latest firmware on watch and Amazfit app on phone. Pair them properly or you may have problems with your activity data in the future (see thread about sync FAQ). If you still have issues, re-install Amazfit and enable the "Away alert" in watch Settings, it seems to make connection much more stable for me...

Amazfit Stratos GPS not usable

Hi All.
I recently got an Amazfit Stratos and I am having a horrible time trying to gps track my outdoor cycle.
I have tried twice, and both times, the GPS just either:
*Intermittently records data
or
*stops recording gps data altogether.
Basic questions?
Urban areas and Woods... same issue
Urban areas are residential.. no high tall building
Weather was good on both occasions
Yes I am waiting for GPS lock
Heart rate and time measurement continue flawlessly (shows data for the entire ride). It's just GPS tracking that is totally weird.
P.S. It's not "drifting" or inaccurate.. it seems to only switch on the gps sporadically... recording "every now and then"...
No errors or issues reported during the activity.
Latest Firmware (Although last nights a new firmware popped up, haven't tried the activity with last night's firmware.)
Both previous activities was on latest firmware at the time. (Yesterday and the day before)
And the REAL issue for me really, is that my wife's Pace records perfectly on the exact same routes where my Stratos just can't get anything usable going...
I have logged "feedback" request with logs using the app, but have not had any response other than, thanks.. we may use your feedback in the future...
From my own conclusions, the gps works.. because when it tracks... the location where it tracks is accurate.. it just doesn't track constantly. See my attached screenshot of my last ride. (Where my wife and her Amazfit pace tracked perfectly)
Any Ideas?
Cant add the image due to post count... How do I add it to this post?
Have you tried factory reset of the watch? Procedure is to unpair it from the app, it will reset itself, start fresh clean and ask for a pairing.
After pairing it will load last 7 days of your work, while all other old data will remain in the app, on your Mi account cloud. What you will have to add separately are only the 3rd party watchfaces, if you have installed them before.
Strongly suggest you try this first, it takes 5 minutes of your time, and you will lose no data.

Thanks Nidza. I will surely try this. I have not yet as the watch is brand new. Upon receiving it It upgraded firmware 3 times from out of the box, and then I started using it.
I will give it a try, surely cant hurt.
Well what do you know. That factory reset seems to have done the trick!
Thanks!
Some points worth noting:
from the factory settings, a few watch settings did not pull through from the sync back to the app after factory reset.
Time format: My previous time format was 24h (Doubt that makes a difference)
Auto Sync: After factory reset, auto sync is off (I had it "on" before). Can't say if this actually causes any bugs to pop up? Maybe the watch tried to sync which interfered with gps functions? I used it yesterday with auto sync off and it worked well. I will investigate if auto sync on causes the GPS issue again.
Thanks again.
Hi guys, is it normal, that my Stratos's Gps show me the speed to much delayed. I checked it with my car, and the gps gets to the same speed as my phone's one, but maybe 10 seconds later. By skiing it can mean worse maximum speed measurement. It is like that with all the Amazefit Startos watches or I have a wrong one? Thanks for the answers!
It's not the same sampling frequency for a car as it is for a walking man. Watch gps do not need to detect non-human speeds, so there is a lower sampling. (Slower).
Same issue again FW version 4.2.8.0:
stops recording gps data altogether after a few minutes.
I've reset and unpaired the clock twice but the issue remains.
Any advice?

amazfit stratos finish point problem

Hello, I have a problem with my stratos and I would like to know if anybody else has this problem or how to fix it.
When I finish my run and then sync with phone and open the app to check my run the finish flag on the map is not on the proper spot but 2-3km sooner.
For example, I run about 15 km but on 12th km, it sets finish flag but it continues to count distance, pace and so on further. In the app, it shows proper distance and everything seems ok but when I look on the map finish flag is on 12th km.
It seems like no issue at all but after uploading on Strava it cuts off everything after the finish flag, so it shows only those 12kms and nothing else. And this bothers me because I use Strava as my primary app to analyze my runs. Interesting is that no matter how long I run it always cuts off more or less the same distance around 2-3 km before the real finish.
I appreciate any help.
Go to Settings on wacth -> Activity reminders, set both to ON, save, then set both to OFF again (you must reset them).
If watch is running firmware > 2.3.7.0 then there is a bug when GPS signal is lost that didn't happen in the past. You may want to factory reset but do NOT restore old data to watch to reset all data, do the above again (also reset Activity reminders), make sure you get a strong GPS-fix before starting to record any activity. And to get better HR data, enable continuous HR for at least 24h and use the watch while you sleep to record resting rate.

Thanks for the reply.
I tried reset activity reminders but it did happen again. The watches are running on 2.3.9.0 and this problem first time occurred on 7th January. Is it possible that some update came out around that date?
About the GPS when I get a green screen which indicated good GPS lock and I start the activity it shows always altitude like -20000m and it takes some time until altitude becomes accurate but I always wait on the same spot till it's ok. Could that be a problem? Should I wait to start tracking even though GPS is ready?
After factory reset can I upgrade the watches to the current version or I should stay on some older one?
Reseting data will only erase the activity data stored on watch, it won't affect firmware. I'd suggest that you do the procedure above, and also turn off the watch for about 15s to reset sensors. And find start to record the activity as soon as you get a green GO, wait a few seconds for a stronger GPS fix.
Hello, I have the same exact problem on Amazfit Pace. It happens on Cycling and Walk and always cut the last 1-2 km of the track before the arrive regardless of the length of the ride.
I would try the suggested solutions but I can't find Activity reminders on Pace.

On the Stratos Activity Reminders are found under Settings > General. Not sure if it will be the same on the Pace.

Amazfit ended up replacing my watch for this issue. None of the fixes they suggested worked. If they are hesitant to replace the watch, remind them of the Satisfaction Guarantee slip included in the package when you purchased the watch.
I have the same problem on my Amazfit pace... So annoying!
Has anyone found a fix?

Hello, I have the same kind of problem.
My watch : Amazfit Pace 2.8.5.0
It happens only when the run is more than 15km
The finish flag is about 1.5 km to short.
The total distance is ok on Zepp App but it is not good in Strava.

Does anyone has a fix?
did you ever tryed a climb and see what the altitude map shows you?
I think my issue (https://forum.xda-developers.com/t/...os-3-2020-12-03.4033223/page-25#post-84231665) is because of that...

Hi.
First sorry for my english.
I have same issue. Zepp is the problem. GPX data from watch is ok. When it is updated to Zepp, data is ok.
But when you download the .gpx from Zepp (like Strava should), the latest data is missing in the .gpx
I opened a ticket at Amazfit but for them everything is fine.
In the screenshot below, we see on the left my watch's .gpx on the left and Zepp's .gpx on the right. There are 30 seconds of data missing.

Amazfit App 3.1.0play synced but no information coming through (Pace)

Hi,
I have just got the AmazFit pace and it has synced up to my phone (Pixel 3A) without any trouble.
I get the notifications etc on the watch.
However my app says 0 for the step count, no sleep data, no heart rate data etc.
i have tried factoery reset on the watch and installing ver 2.9 of the app on my phone with no success.
when i press sync on the phone it connects to wifi and claims to have successfully synced data but it isnt coming through to the phone.
Any help would be great.
I've tried searching for similar threads, the only thing similar i've found mentioned his firewall blocking the app but i dont think that will be the issue.
Thanks
The watch is brand new? Was it ever paired with another device previously? If yes, it has to be properly unpaired first, or activity/health data won't be synced properly. If no, it may take 24h for the data to sync properly. Try recording a dummy Elipitical activity and using the Sync from watch (it needs to connect to a 2.4GHz access point).

Thanks for the reply
yeah, the watch is brand new.
My partner bought it, tried pairing it with her phone and had the same issue. I unpaired it, the watch factory reset when unpaired and then i tried it with mine.
I expected the pedometer to increase in real time.
does it sync via bluetooth or only via wifi?
Edit: I tried a dummy elliptical and that has synced. But im still not getting any heart rate or steps info even though i have done a few heart rate readings and obviously taken some steps
Sync is actually done in two parts: first the phone pulls data from watch using Bluetooth, then pushes the data to the cloud (Huami) via WiFi (this last part is what is done if you use Sync from watch settings). Only when the data is pushed successfully to the could it will be shown in the app on phone. If the sync gets stuck at 100% then try restarting the phone, then try again and if it doesn't work restart the watch too.
Steps will sync alright ,but dont expect to sync heartrate .
Amazfit will display heart rate only when Pace' s heartrate is set to continuous mode.
Howevrer as soon as continuous mode is diabled , Amazfit will lose all heartrate data .
This means that the problem is not with connection,but with Amazfit syncing heartrate to Amazfit account .
This app is so bad and buggy .
I have no issues here syncing data. Try unpairing the watch while it is connect to phone, so it will factory reset (all data will be erased), then do NOT restore old data to watch when you pair again. For better results, also uninstall Amazfit Watch app before pairing again, and login using the same account to restore your old data (to phone only).

I have tried this method numerous times already.
As i said, everything synced alright with the exception of heartrate.
Heartrate data doesn't get retrained when continuous heartrate on watch is disabled.
I have tested here, and it works on both Android and iOS: as soon as I disable continuous HR it will show previous manual HR data.

It's supposed to show previous continuous HR data as well after HR being disabled, similar to the MI-Fit App.
That's how you would know your HR performance for the duration that it was continuously measured.
HR measurement, if working properly, should retain those data, as in STEPS and SLEEP data, so you can refer to how your heart rate does for periods that have been recorded.
P.S. the Exercise sessions recorded and retained continuous heart rate data without any problem. One can always check back at the continuous heart rate chart when the exercise session was recorded.
