So over the night my Fenix 6x Pro Solar auto updated to firmware 6.60. I was excited, but when I went to bed my percentage was at about 58%, but then when I woke up it was at 30%. In the last couple hours along with keeping the watch in the sun charging I have already dropped 2%. I did a restart first thing this morning.
Not sure if others are experiencing this.
I'm seeing severe battery drain too (Fenix 6 Pro) since last night. I seem to be dropping ~3%/hr, and that's without doing any activities/GPS/music/etc. - just using it as a normal watch with HR monitoring…
Garmin sent out an update that they are downgrading the 16.60 down to 15.20 due to the battery issues. That is why you see what you are seeing.
To me it is nice to see that Garmin looks at these forums…
Press-and-hold top left button for a good few seconds (30 or so?) until the watch turns off. I waited another 30 secs then restarted as normal. Good luck!
