I'm a new iPad and iPhone user and I'm a little freaked out about what just happened to my iPhone 5. 2 weeks ago I had to exchange my iPhone 5 at the Apple Store for a new one because it would no longer charge. It was just defective. I recently learned from the Apple website that I'm supposed to run my phone through a complete battery cycle for maximum battery life. The Apple Store employee didn't blame me for ruining the phone, he just replaced it. But I want to take good care of my new one (and my iPad). My questions are: ---Should I let it run down to RED, 20%, 10% or complete shutoff each month? ----Should I do the same for my iPad? ----If you don't do this, how long will the battery last before replacement? ----My iPhone also serves as my iPod (music container). I can't plug it in when I'm driving my Prius without it charging, which wouldn't let me cycle it each month. So I have to do without music for 3 days each month? What does everyone else do? I got rid of my 2 iPods. Thanks.
