So why not just set it for your "usual time" and on the rare occassion you are out and about turn DND off? I plan my life around the 80/20 rule. If 80% of the time I do X, then I set my settings for that so that only on the 20% of the time I am not doing X that I change my settings.Yes. That is absolutely what I am saying. It should be automatic. A simple "if, then" command:
IF it is between xx:xx PM and yy:yy AM
AND plugged in
THEN activate do not disturb
I shouldn't have to go into settings to change things every night. On the Blackberry this was all automatic.
Edit: And yes, having a setting for charging would be nice. Frankly Apple just added DND with iOS 6 so prior to that we were all using the Sock/Cloth method mentioned previous! DND his a huge leap forward for us.
