We both know mah isn't all that matters, software and system architecture are arguably more important. FWIW I probably charge my 12 mini less than once per day

We both know mah isn't all that matters, software and system architecture are arguably more important. FWIW I probably charge my 12 mini less than once per day (not even overnight). Yes I use a powerbank on multiday backcountry trips, but it stays in my pack, not on my person and especially not in my hand.
