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…
I've just got a Coros Pace 2 - as you can see from my Fenix 6 Sapphire, the battery is at 15% and I only charged the damn thing 4 days ago....less than 4 hours GPS in that time. So I'll be charging on day 5 (tomorrow) as usual....
I'm curious to see how it stacks up battery wise. 
That makes two of us
This might interest you then.
So this morning about 20 minutes before a 42 minute run this was the battery status of both.
Before (at that time of day my F6 is still in sleep power save mode)
After (my Fenix 6 ran out of power at about 37 minutes)
So Pace 2 used 5% on this run (which IMHO is quite high really) but Fenix 6 used it's last 10% and I lost about 1 mile from the as the F6 shut down mid run.
Frankly, it is not correct to compare pace 2 with Fenix 6x. The equivalent is FR245.
Agreed. The only thing that makes the 245 not an option for me is no power meter support.
I also tried sleep tracking (3 hrs and 53 mins deep sleep? ). I must say both functions are not even close to Garmin IMO.
So I have put my Fenix 6 Pro on charge and got my sleep data out, 5h 03 minutes Fenix 6, 5 hours 10 minutes from Coros, 5 hours feel about right.
So for pace when running, my feeling - and this is just a feeling as I have only run with it once is that live or instant pace is better than the Fenix 6, far fewer wild swings - I went up to 6:00 /mi pace (my 5k pace) and the Coros was showing 5:55 /mi and holding stready so live pace feels OK. Unfortunately as that point my Fenix 6 ran out of power but I will see if I have any pace data in my .FIT file before the power cut out.
My feeling is that for running the Pace 2 will be very good - I think for general health metrics not so much. But that's just having owned it for 24 hours.
On the other hand, 10% situation of your fenix. What a frustration :(.
Yes, so yesterday about 19 hours ago my Fenix 6 had 15% battery, and then dead mid-run.
And a quick look at Coros wrist HR vs Fenix with HRM Pro (you can see when the power cut out from my Fenix 6 there!) - normally optical wrist HR is unusable for me due to cadance locks, but the data there looks fairly OK.
And it was in low power mode from 10PM. But charging every 5 days is usual for me since 19.20. Too be fair, even before 19:20, 7 to 8 days maximum before needing to recharge. But the battery loss since 19.20 is a very clear and obvious pattern.
