Fenix 6 battery life reduction after updating ?

Nick

Hey guys, 

I did a little work on my app two weeks ago, and for the first time in a while plugged my watch into the PC to update the settings and sideload the app for testing.

I've noticed ever since approximately then, my battery life has gone down the drain. Now I don't know if the cause is linked to my app update, or if the watch downloaded a firmware update when I connected it.

To put in perspective, at 2 pm today, I checked the battery time left and it said 1 day ( that is about 2 days after a full charge, and no app use ).

Then I went into power saver mode on the main menu, and it changed to 4 days left, with 9% power. I did not touch the watch, and 4 hours later it was flat.

It seems that the watch is taking itself out of the power saving mode and turning on stuff to flatten the battery faster? 

Does anyone know how the power saving modes are supposed to work? 

Ie - I select one on that has GPS and wifi disabled. If I then select an activity that uses GPS, once the activity is finished, does it not go back into power saving mode again automatically?

  • It definitely sounds like you are seeing a battery drain issue. It is typically difficult to find the cause of issues like this.

    There are a bunch of questions that will help to figure out what is going on.

    1. What fenix6 device are you using (be specific, fenix 6, 6 pro, 6s, 6s pro, 6x pro, 6x pro solar, ...)?
    2. What firmware version are you using?
    3. Do you use a ConnectIQ watch face?
      1. Which one(s)?
    4. Do you have any ConnectIQ apps installed?
      1. Which one(s)?
    5. If Yes to #3, does the problem reduce or disappear if you use a native watch face?
    6. If Yes to #4, does the problem reduce or disappear if you uninstall all ConnectIQ apps?
    7. What if you disable BLE/WiFi

    I know that the device teams have some tools available for debugging problems like this, but until we are able to reproduce or have some idea about the source we are kinda stuck.

    Thanks for the tips - it seems to have fixed itself by me entering the battery saver mode after charging it. Although I notice that when I take the device off the charger, the watch face that I see is not the battery saver watch face, even though battery saver I have manually turned on prior to charging. I'll keep an eye on it next time I charge to see if that is what is happening, but 31 days charge yesterday, 30 days today so far so good.

    Ok, so i get back from work today.  Look at the watch and it has taken itself out of power saver mode, and I've gone down to 21 days. Power is at 97%. Is this a function of the solar model, to stop overcharging it disables power saver if near 100%.

    So - the watch seems to be taking itself in and out of battery saver mode, without me initiating any activities. And post charging, it's out of battery saver mode and I have to manually turn it back on. Is this normal?

    Unfortunately, I don't have access to a solar device to test, so I'll have to get someone who has one to check it out.
