Excessive battery drain

David
over 3 years ago

The last few days my battery is draining super fast.  Even without doing activities and just in daily use the watch isn't lasting a single day of use.

I've tried power cycling, doing the press & hold of the light button for forced reset, turning off all the sensors, disabling wifi, but nothing is slowing down the battery drain.

Anyone else seeing anything like this?

EDIT:  I'm not sure how the battery level is being detected, but maybe it is not registering correctly.  It drained from 10% to 1% in less then an hour, but then sat on 1% for an hour without shutting down.  Maybe I will try and let it go until it drains completely and see what happens.

    Same here loosing close to 50% in 24 hour (including a 45 min gps run). It started around the time I upgraded my iPhone to iOS 15 so I’m wondering if there’s a relation

    I contacted support and am sending it in for service. 

    The only other time I have seen drain this bad was due to a hardware defect, so maybe something similar here.  

    Back to the Forerunner 620 for the next few days, which I have had for about 8 years and still works great, and holds a charge great.

    Not saying it can’t happen, but my 12 Pro Max has been on iOS 15 since the beta was released months ago (now on iOS 15.1 beta 2), and haven’t had any issues with battery drain on my 945. Wife just upgraded to iOS 15 and her 945 hasn’t had any excessive battery drain either.

    I forgot to reply on this.  I dont use apple phones, so for me I know for sure it isnt an Iphone update.

    Update,

    my battery lasted 5 days with 2-3 30 min exercices, I turned off the pulsioximeter and (with no exercise,... mild flu...) very little notifications, after 3,5 days still 83% battery, so  pulsioximeter not reliable and a battery eater.

    Thanks for the tip about PulseOx.  It might help some other people, but it was not the cause of my problems.  I already knew that it was a battery drainer, so it was the first thing I disabled.  In the end calling Garmin Support was the best thing to do.  I got a replacement watch and the battery life is back where it should be.  Now if they could just fix that Jaybird disconnect issue, I would be so happy.
