After updating my Fenix 6X to version 19.20, my battery is draining extremely fast. I took my watch off the charger at 0600 this morning with 100% and by 1400 it was already down to 70% charge. Before the update I would maybe be at 97%. I haven’t even used the device to track any activity, listen to music, and my pulse ox is turned off.
Me too
My battery life is awful now.
Fenix 6s
It's nearly half what it was (and i had pulseOx on all day before). I'm basically getting a day less endurance for approx 50% battery consumed. I was getting…
Same here, about 30% per day
Before the update batery lasted 7 days, today 3 days
hopping fast solution for this issue
Yes. It is now on 79% after a 42 minute dog walk with GPS+GLONASS, WHR and Tempe connected. There was also 10-15 minutes GPS soak while driving to the park.

The only evidence I have of the drop from…
Ah ok 
Congrats on starting a monster thread :) and exposing serious issues with Garmin when it comes to know knowing if their issue is hardware or software related. I hope you got your issue fixed?
Either way, sorry to enter the fray, but I had the same issue for 2 days straight after autoupdate to v20 and I don't anymore.
What I did was to use Garmin Express to update my maps, which is something I have never done before because I never need them. Also, Express said it couldn't synch two of my .fit files, so I deleted them manually. Charged it back to 100% and first it didnt drain at all for almost 10h, now it is back to a typical 0.3%/h rate. Hope this may help anyone who is still dealing with this. Also apologize if this was already suggested, but I didn't feel like wading through 45 pags of thread! 
Happy days!

So I am just about to send Garmin another set of logs - but as a picture says 1000 words here are 2 pictures 24 hours apart.
F6X on 20.01, F6 Titanium on 15.20 - 47 minutes of indoor riding only in this 24 hour period.
For anyone who didn't see my rollback to 15.20, the F6 Titanium would also drain rapidly prior to rollback (not quite as bad though, it lasted 4 to 5 days rather than 3)
No, they never sent me any of this. I hope that here in Italy they have understood that this is not
a problem for a few people.
But I'm sorry to say, in Italy we are always light years behind.
