Massive battery drain on Fenix 7s watch

Mustafa
25 days ago

I am seeing massive drop in battery percentage for my Fenix 7s watch. 


I fully charged it yesterday to a 100% and basically left it on power saving mode (as I always do while not using it) not even wearing it for the rest of the day or overnight, only to pick it up the next morning at 30%.

I am on latest software 18.6.

Any help fixing this issue? I have a long distance race coming up next week and afraid it's not going to survive for the whole duration with this drainage rate.

I tried the soft reboot as mentioned in other threads with no luck. Still draining very quickly. 
I also did not change any setting for a couple of months now (it battery was just fine a couple of weeks ago). 

I have pulse ox set to manual check and pretty sure I am taking good care of what is running in the background and which apps are on. 
I have no third party apps installed through connect IQ store.

    Hello Mustafa,

    Our engineers have been investigating battery drain concern for the Fenix 7 Non Pro series for some time. And have reviewed all the examples and usage logs you have provided. Thank you for this. They have not found the battery drain to be software related. 

    So if you are experiencing rapid battery drain, please try these following steps: 

    • Consider your device settings. The following will drain your watch more rapidly: 
      • Backlight
      • Music
      • Large number of notifications
      • Headphones usage
      • GPS activities
      • Some Connect IQ apps and watch faces
    • Here are some additional battery settings to consider: Tips for maximizing battery life
    • Try cleaning the contacts on the back of the watch and cable. For this we recommend using rubbing alcohol.
    • Try a hard reset. For this, hold the Light button until the watch shuts off, as opposed to selecting power off. Then power this on again. 
    • If you have owned the watch more than 3 years, we do see a decline in battery life after 3 years of usage. 

    If this continues, we would recommend contacting Garmin Product Support to determine if the device needs to be replaced.

    If you are using a Fenix 7 Pro series, this concern is still being investigated. I will provide updates, as they are available.

    Copy pasted response from other threads. Our team of engineers have investigated themselves and found nothing wrong with the software they created. 

    I have not provided you with any usage logs or examples what are you talking about?

    The watch is still barely a year and a couple of months old. This is such a ridiculous answer.
