Each, and every time I go home I shut it down, than back on again when I go out. No issues. I do not use the alarm clock either. I had the iPhone 5s.
I use it for some GPS once a month at most, one or two voice texting per week, very few photos, very few phone calls (Not a kid), no music (Great system at home ), very few e-mails, very little SIRI use, no movies (HDTV is for that).
Not young, am retired, I have two computers in the home, so I don't play with my iPhone like others do. Have a real life
I get over 4 days on battery.
