Out of curiosity, when you guys with the Fenix 6 say insane battery life, how long are you talking?
I have the 6X Pro, which is supposed to have a bigger battery vs the 6/6S and whilst it is insane during activity and can handle a run of about 60 hours if needed. I still find myself charging it maybe every 4/5 days. Obviously that's still a lot better than most watches and i do use it for ~1hr workout a day on average (Using a HR strap, no music), but i always read about people not charging theirs for 2 weeks and curious if that's actually genuine in regular use or just for people who turn everything off and don't track exercise.
It's a bit of a guess but my fenix 6 non-pro gets a charge every 7-10 days. That's with around 15 activity hours per week (using GPS) and with the pulse oximeter turned off (everything else is default I think).
