[Guide] Battery Drain Issues - Tips for Pace/Stratos - Amazfit

If you don't have a damaged watch, either eventual defect or water damage (remember, Pace is IP67 what means it only resists to eventual water submersion, not shower, not pool, etc, Stratos is OK for swimming, etc, of course), then most probably it's a sync or Bluetooth issue.
Note that all tests are done with stock firmware (no custom ROM) and the correct Amazfit app installed and only the correct one (CN Amazfit for Chinese ROMs and EN one for international Pace). If you have installed any APK, also uninstall them as they may cause problems. If you have unlocked watch's bootloader or flashed another firmware remember that you did it on your own risk, and now your warranty is voided and you cannot return the watch.
First thing to check if watch is good: enabled Airplane mode on your watch and observe battery drain for a few hours using the recommended settings in the end of the post. Make sure there are no alarms configured in the watch. This way the watch cannot use more than 10% of battery per hour. If it does then probably you have a hardware problem. Factory reset watch (it will erase all data on watch) and answer NO when Amazfit app asks if you want to restore old data (it may be corrupted, causing sync to not work and drain battery much faster), then try again. If it is still the same, probably it's defective.
Once you are sure the watch is fine, let's find out what is causing the problem...
Some phones have issues with Bluetooth and WiFi, making syncing with the watch not reliable, so the watch will drain much more battery trying to connect and sync data all the time. You can test this by putting the phone in Airplane mode and enabling only Bluetooth, then check the battery for a few hours. Or test with another phone the same way.
The other cause is a result of corrupted data or problems syncing with either Amazfit or Strava cloud. First, go to watch settings and disable Autoupload, then remove or pause Strava syncing. If this fixes your problem, then you must fix the sync with Strava somehow, maybe reset your data on Strava, create a new account for sync with Amazfit or update data manually.
If it doesn't fix then probably you have errors when opening Amazfit app, it shows a red bar at the bottom instead of a green one when syncing data. In this case you can try to unpair and pair the watch again, and choose NO when it asks if you want to retrieve the old data. If it doesn't help, try unpairing and creating a new account for Amazfit app, then pair the watch using the new account.
To increase battery life (with tips from group members):
- Make sure "continuous heart rate measurement" is OFF on the HR widget (don't worry, it will always measure HR during activities);
- Turn "Auto upload" in watch Settings to OFF;
- Turn brightness to zero when outside (you won't need it in day light);
- Turn "Awake on wrist movement" OFF (awake screen with button or enable double tap in watch settings);
- Use Airplane mode when away from phone and/or auto Airplane mode at night while you sleep (don't worry, it will monitor your sleep even in airplane mode);
- Alarms on watch use a lot of battery even if they are disabled (bug maybe?), so *delete all alarms* on watch if you are not using them;
- Avoid discharging the watch bellow 10%, it's not good for the battery;
- Also avoid leaving the watch on charger for long periods (>24h);
- If you won't use the watch for many days, turn it off with battery > 50%;
- To get actual full charge, leave the watch on charger for more or less 30min after it shows 100% charged to really fill the battery completely with trickle charging;
- If the watch is new, battery will get better after you fully charge it 3-5 times, simply follow the instructions above.
Other tips are welcome. Cheers!

Good article
I had a problem with my watches occasional battery drainage. The problem was at a phone side.
There was a bad thumbnail file at DCIM phone directory. File was not readible. After deleting this file phone self restarts were gone and phone battery life was prolonged. Occasional watches battery drainage was also gone.
PS. I found bad file when tried to backup my photos to PC. I can recommend to try to copy all files from your device to somewere else to try to find file system problem instead of commencing device hard reset.

Hello. This seems to be a hardware failure. If you factory reset the watch (warning: it will delete all data on watch, so sync with app first) and it still behaves the same way, then the watch has a hardware failure and it cannot be fixed via software.

Suggestion...
I've had my pace for almost 2 weeks, and was getting about 3 to 4 days were I expected at least 5, since I've never used the GPS nor continuous heart rate monitoring. Also in the first day, it went from 100% to 70% before the night.
I've been reading about battery drain and I think I found the culprit in my case.(less than a day testing the theory)
I've read that problems with Bluetooth communication may cause battery drain. In my case, it's not exactly that the watch disconnected or I didn't receive notifications, but I associated that with the fact that I have a notification filtering app that instructed me to configure it to be excluded from the battery management (android 8).
After I did that with the amazfit app , I've seen a lot less drain.
I offer this as something to try in a similar scenario.

I suffered also under huge battery drain while using external bluetooth hardware with my Stratos (i.e. hr belt).
Yesterday i installed AmazMod on my phone and my Stratos, which modifies the notification system (look up for more information in AmazMod thread).
Today i rode my roadbike about one hour to work and as usual i connected my bt hr belt and battery drain was about 4%... all the other times battery drain was about 20%.
I think that something is messed up with the Stock notification system while connected to an external BT device.

[SOLVED] Battery drain issue for Amazfit Pace
Hi all,
I've finally solved the battery drain issue for my Amazfit Pace I've bought one year ago.
I would like to underline that I've always washed the watch under the shower and also when I washed my hands. The smartwatch is IP67 certified, that means IP67 means the unit can be dropped into a body of water up to a meter deep for half an hour.
My problems raised when I forgot the watch at my hand, during a sea swim. Even if the Amazfit pace is water resistant and the water has not entered into the unit, salt minerals entered into the only hole on the smartwatch: the microphone hole.
When I opened the unit, I've found that all contacts were in perfect condition without any oxide on components and smartwatch internal parts. The small paper placed on the mainboard to verify if water entered inside the smartwatch, had not changed color from blank to red, meaning no water presence.
However, in some way some salt has affected the microphone causing oxidation and short circuit: this is the cause of battery drain.
The microphone is protected by a plastic dress fitting its shape and at the end of the hole there is a thin membrane that should prevent water to enter but maybe is not so resistant to small salt minerals.
I solved the problem washing the microphone with isopropylic alchol and then removing the oxidation residuals with a small tip.
Now the battery discharged in 5-6 days as expected for a normal use in airplane mode.
Considering that microphone function is not so useful because there is no correct and plain translation from chinese to english or other languages, you can think to close the hole with some plastic material or, as I've done, with a small drop of plastic glue in order to close the hole avoiding voice blocking.
I hope my experience can help!

Amazmod Bluetooth HRM hack

He already did:
1. It shows a connection/disconnection alert;
2. You can disabled stock Amazfit notifications and use only the ones from AmazMod, if your setup has a connection/configuration problem this may fix or simply circumvent the issue.

Not working.....
Hello!
I have the same problem,with my Pace, the battery drain fast(10%/h).I removed the mic+barometer unit, but the problem not solved. It's drain like it before. I don's saw any oxidation or water inside, dry and clean everywhere.
I try factory reset, with and without restore data, not connect to phone,etc. I bought is about half year. It's with original firmware, never mod.
Are there any idea, what is the problem?

---

Upgrade the Stratos Watch with the last release 2.3.10.4.
This is the best tips to get a very good autonomy: 6 full days always connected to the Smartphone but without GPS sports activation.
Before this release, it was limited to 5 days max.

Amazefit pace - battery got drained from daily goal being set to different then 8000
Hi everyone,
I started experiencing battery drop on my amazfit pace like two weeks ago. Performance drop from 6 days on AVG to just 2-3. This happened without having any new updates (both watch and phone). I tried resetting the device + uninstall/install the App on my phone - all without any luck. I was just considering buying a new one when I decided to do a careful retrospective for the past two weeks, especially the period when the problem occur. And then BAAM! The only thing I had changed back then was an increase of my daily goal from 8000 to 10000 steps. I can now confirm this was causing my issue with the battery! Some how the default value (8000 steps) is optimized for battery usage comparing to other "custom" values. Again for me that means 50% off my overall battery life. INSANE!
I hope that helps! And I really hope someone from the support of that device read and double check that (in my opinion bug)
Cheers!
Stefan

Amazfit pace battery drain issue resolved
Dears, on my amazfit pace I have the same battery drain issue. It takes only one day on full charge. I have factory reset many times but still the same problem.
At last i un installed amazfit pace app from my phone and reinstalled a fresh setup while watch also factory reset the same time. After doing so I reconnected as a new new and fresh with bluetooth, Alhamdulillah my issue resolved all at once. Enjoy :good:
