Garmin Fenix 6x battery in the practice

On my fenix 6x it's said I've got 18 days battery for the last 3 days. So idk what's going on there. The days on it for battery life seem to decrease every 1 to 3 days per day if you get me. 

Well, it really depends. I'm testing a lot of different watch faces, have a couple of outdoor activities recorded and use as much sensors as I own and have to admit that the F6X Pro is hungry. I'm having a hard time to survive a week right now but my experience with the F5X was similar until a certain progression of firmware and 3rd party apps settled the consumption down a bit.

My 6x typically lasts 1 to 2 weeks. It shows 21 days of expected battery life after loading it to 100%.

I recently upgraded from the 5x and received the 6x Sept 20. I fully charged it and I am on day 12 and I am at 38%.  Ive used it 3-4 days a week for about an hour running.  Recovering for an injury right now so I havent been able to get out for long trail runs yet

Same. I record about 2 activities per week on average, for a few hours each. My brightness is at 10% with a 60second timeout (and always-on during activities after sunset), BT and notifications are on, all-day WHR, and I'm using a heavily processor-intensive watchface (SC1).

I've had Sleep PulseOX turned on for the last week or so (to try to help figure out some sleep issues I've been having). So it's been on the lower end of that range lately, but when I've had Sleep OX turned off before, it gets closer to the higher end of that range.

I think the best I've gotten was 11 or 12 days, but I'd expect that'll improve after the "newness" of this watch wears off and I lose interest in playing around with it constantly all day.

One thing I'll say for certain, is that I have ZERO concerns about running out of battery during an activity anymore. With my old Vivoactive 3, it only lasted about 8 hours during an activity, starting with a full charge. Which means it inevitably always died (and lost its recorded data from that activity) before finishing all the longer hikes I've done. Which was totally unacceptible. There's no worries about that anymore, the 6X will go for days recording an activity.

What is your settings in smart watch mode? 

Is BT on?

WHR?

Activity tracking?

BT is always on for me. I'm using the optical heart rate sensor of the watch all of the time. And GPS+GLONAS for GPS tracking.

I have been getting 18-19 days worth as promised, with pulse ox=off, wrh=on, bt=on, brightness=50%, gesture=off

if I use the watch for 1hr/day for GPS activities (walking, running), it drops the total battery to 9days. The GPS is set to GPS+GLONAS and data recording set to 1sec 

as an aside, i charge the watch up to 85% and don't let it go under 20% so the above numbers I quoted are a calculation - I haven't actually let the watch discharge until it shuts off.

With activity tracking, bt, whr and wifi on the battery lost about 0,8%/hour. That would give me aprox 5,5 days. Then I turned BT off and the new consumption is between 0,1-0,2%/hour.

I hope a new update will fix the batteryusage from the BT connection.

Very similar for me, I'm running SC1 as watch face and I have about 0,8% per hour as well. With about one activity per day I have to recharge the watch every 4th or 5th day. As soon as I'm out of range of my BT connected phone, consumption goes down.
