Your individual use case is definitely the prime consideration. I’m in the same group as your buddy, I track my sleep as well as target work tracking (aka stress level) and workouts. Due to that my charging ‘rhythm’ is a defined period onto the fast charger while I shower and then have a cup of coffee. For me the fast charge upgrade from S6 to S7 made my daily usage flow line up so much better.
Go with what your use case needs. And if yiur use case changes, it is easy enough to grab a USBC brick
. One friendly suggestion, at some point in the future try to start tracking sleep. The sleep pattern coupled with BPM and O2 during sleep is very valuable health info. And a surprisingly less know but nice benefit, waking up via a pulse on the wrist versus a sharp audio tone from my iPhone.
Cheers…
