Funny you should ask that. I just got a Series 5 SS on the Best Buy deal and noticed a huge hit on battery between AOD On and Off. I have now setup 5 Shortcut Automations (2 of which will not be used until things are back to normal with Work). I have AOD turn on when I leave home or work, turn off when I arrive at home or work, and I have it turn on when I start a workout (in case it isn't on already).Can you do this with a shortcut automation?
I now wish there was a DND shortcut for the Apple Watch so that when I start a walking workout, it would disable DND since I like that on when I bike ride or run, but when I log a walk, I'd like notifications to still alert me.
