We have identified a possible issue with software version 13.40 for the fenix 5 that can cause additional battery drain to take place. If you are experiencing increased battery drain on your fenix 5, update…
Hi,
I made some tests during the last days and I found what causes that heavy battery brain on my Fenix 5s.
I used the following widget to take my measurements https://apps.garmin.com/fr-FR/apps/5e49aebc…
hi,
Hello
from a week I installed the fw 12 ... my watch is reborn ... currently I am at 60% of autonomy and it is from last week that I do not load it since I installed the fw (and it was 90%).
Same for me, draining about 1,5% per hour, without optical HR back to the usual... I'm really dissapointed, I had same issu with my FR235, whith 4changes from GArmin!!! Now I have the fenix 5 and same history... I should bought a Polar...
I should say I'm "happy" not to be alone in the case.
I have the F5 for a year and usual battery drain without activity was around 7 to 8% a day, I could last for a week with 3 activities. And for 2 weeks now, battery drain is about 20% a day without activity.
Tried several things and the only thing that makes significant change (but still heavier than 7-8%) is to turn Bluetooth off and sync manually.
I upgraded yesterday to last version. No noticeable change to the issue.
I wonder what they do at Garmin to decrease their device quality like that. Aren't they running regression testing or so ? Such a disappointment for a watch this price and this segment.
Hi All
Glad to see I’m not the only one with this problem. Since last 2 weeks my Fenix5 battery life dropped from 10-12 days to 3 days with very limied activity. I’ve updated software to version 14 and no difference. It’s very annoying for a watch this value. Can Garmun please give us some feedback is this would be resolved?
Hye everyone
Here is how I did to '' solve'' the battery issue.
I mean it is a trick but still waiting an update to fix everything.
Ive noticed the issue come from the HR sensor.
So I get back to 13.51 bêta and when I dont need it I turn off HR sensor.
Now i have less than 0.4% per hour.
Hi Shent-Aurkhan,
It is not easy for the standard user to roll back versions.
Moreover, it seems we are not experiencing the same source of issue. eg, in my case, the HR sensor is on all the time and doesn't cause major drain. But as soon as I turn bluetooth on to connect to the smartphone, drain resume.
So, I turned my bluetooth off, meaning no sync, no notification anymore on the watch, and do the synchronization manually when turning the bluetooth on for some minutes. So doing, the battery drain remains under control.
What striked me also is I didn't do any update on the watch when the drain started. It just came one day. So, I do suspect the issue might not be on the watch or watch firmware but on the App. On my smartphone the updates are automated, so what COULD have happened is a version update of the application which then requires more sync from the watch and would drain the battery.
Hope someone at Garmin one day will take the time to reply to the users (and payers) we all are.
I am having the same problem on my Fenix 5
Hi everyone.
Only remedy is to install 13.51.
I had 14.x
first download all files from 13,51
then follow instructions BUT first Start from droping 13.30 file into proper folder. Proceed with other files (dont copy 13.51 on this stage).
Disconnent from pc. You garmin will notice about system upgrade. Do it.
Restart.
Then connect to oc again again and start all the procedures but with 13.51 file.
Disconnect. Upgrade to 13.51. Restart.
Done.
Turn off auto update.
Get back to routine life and wait for any positive feedbacks on new sw version here. And only then - upgrade
)))
