One extreme to to go is to go to the forums where people discuss their gear for hiking Everest or similar. See what their gear and routines are.
As I said, that's extreme - but you can work backwards from there if needed.
I'm in a different group than that - or you - but I need to be just as prepared as you when I head out.
I'm also in BC, and on many weekends at every time of year I'll pack my Jeep and head up behind the mountains in Squamish/Whistler, and I'll take the forest roads as far as they/or I can go - sometimes 100km out of cellular range - and I'll get out and put on my snowshoes and just go... Or in summer I'll just hike... Just for the pure hell of it and the enjoyment of being lost in the deafening silence.
Thing is - I MUST be prepared to be stuck up there. Jeep breaks, gets stuck etc. Even with winch and recovery gear - I'm always alone, on my own and I accept I could get stranded. So, what gear - and electronics is important to me. Citing the same factors like extreme cold etc...
Now, I have a Jeep as a home base. With vehicle batteries and by then a 1/2 tank of gas. So I'd have the ability to charge more easily my phone, portable HAM radios etc.
But simply - I'm realistic here - and I WILL be wearing my AWU when I go from now one - if I get separated from my vehicle and will be away from it for days then the AWU is the least of my concerns, and it will run out of battery soon. More important to me in my phone, radio and bear spray.
I do carry a spare battery unit for charging if needed. With the gear/water on my backpack - you can't even tell you have it.
But if I truly want to be that outdoors guy - I would NOT be wearing an Apple Watch. AW is not made for that type of environment if it's not going to be constantly charged. Simple enough.
I'm not going to try and convince other people though that it's bad for me, or them. They don't know what I go through up there - and it takes a few times of being stuck, being really scared or worried and then when you finally get out - your gear list gets adjusted. Over and over again because you realize what is important to those adventures.
Again, my phone/ham radio is #1. Watch is way, way down on my list. If it was higher I'd be looking at a Garmin.
Stay safe in BC

I'll do the same
