Battery drain fast

Yes I have this issue to, not sure if it was after the software update. Used to go 8 days between charges, now it runs out within 48 hours and I have not changed any settings. I did a reset, no improvement. Updated manually to software 16.3 and it still uses 50% in one day and that is with one activity. I got rid of apps like spotify and dezer (not that I used them through the phone) and only use a Garmin clock face. I am starting to think that there is a problem with the batteries on the Fenix 6x.

They need to fix this, NOW, because these watches were not cheap.

Have just been advised by Garmin support to upload 16.70 OS, have done so and will see if it slows it down, I see the update does say "Fixed issue causing intermittent excessive battery drain."

Ive had my 6x pro for a week now , usually when fully charged it says i have 21 days , NOW it says i have only 10 days on fully charged , why is this ? 

Unfortunately, 16.70 doesn't fix the battery drain, at least for me...  

Me neither...was on 16.60 when it came out, which ruined battery life, upgraded to 16.70 beta which seemed like it had a positive impact, but went for a 1.5 hr walk this morning and used almost 40% battery.

Not fixed for me either. 25% gone in 24hrs, with less than 1h GPS activity. That's beyond ridiculous, Garmin.

Updated software and then left watch sitting on my desk. It got down to 20% after 6 days. The only time I used it was for a 45 minute walk and it dropped about 15% during that with GPS enabled.

So this update does not fix the battery drain issue.

For me it mainly seems to be a gps issue: walked 20min to work with gps: 5% less. Two hours working: nothing changed!

yesterdan ran 40 min without mapping, 12 % less.

Same...suspect a GPS issue. usage on a 1.5hr walk was 15%/hr according to the battery widget. My watch was fine before it was updated to 16.60. I have tried the 16.7 beta and reverting to 15.20 and battery life during activities still sucks.
