I, much like you, live in a daily grind where I can theoretically keep my iPhone and iPad (and MacBook) plugged in 24 hours a day. When I'm at work i can have my iOS devices plugged in at my desk the entire time. When I'm at home I can have my devices plugged in the living room the entire time. When I'm driving to and from wor or going anywhere else I can have my devices plugged in the entire drive. I'm wondering if having my Apple devices plugged in all the time would potentially hurt my fancy products. I ask because I tether my data from my iPhone to both my iPad and MacBook at all hours of the day. Essentially I'm tethering 20 hours a day.
