I kept it off for all of last week and while I was out walking every day, had to either rotate the crown or tap the screen to see how far I had walked. This week, I have raise to wake turned back on. It uses so very little battery power when the display turns on while driving and such and leaving it on is just so convenient.
I am leaning towards this for similar reasons. When running, it's just so much easier to raise my wrist to get information vs using both hands (one to raise, one to tap) to get information. Also, whenever I'm carrying a ton of stuff like groceries and I could use the time or temperature or sundown/sunrise, raise to wake always saves the day. And yeah, it just doesn't use a ton of battery - I still end my day over 80% even with a 30-40 min exercise.
Yeah, I think I'm just going to leave it on. Watch, in a few days I'll go back to being absolutely convinced to leave it off... (though I think I'm going to leave it on for a week to force myself to get used to it because I'm tired of going back and forth).
