Fenix 5 battery drain. Barely lasting workout and charging every other day

Does anyone have any advice or idea on how to fix my Garmin battery drain.

I get maybe 2 days with a full charge 

Even this morning it dropped 5% in the space of 1 hour.

If I'm working out,I have to charge it over night so it's full in the morning for the workout.

Started happening not long after a Spartan race 

Thanks

  • There is a "Search" box at the top of the page. Try searching for "battery drain" and you will find there are already many questions and answers regarding the battery. That might be why you are not getting any answers.

  • Thanks mate. I should of added that I have tried the following: 
    - Restore to factory setting (no change)
    - Soft resets (no change) 
    - Turn off bluetooth (slight change) 
    - Turn off GPS (slight change)

    Next ill try the cleaning trick. 

    It was literally a flip of a switch. 
    Charged and worked for like 5 days. 
    Next charge, lucky to get 2 days and been like that ever since.
