I'm using an iPhone-4S and the first thing I bought was a Mophie Juice Pack Plus Case and Rechargeable Battery. It functions as both case and as an external battery that is always plugged into the iPhone. I keep a charging cable in the truck so I can top it up when I'm driving. Fortunately, it seems to be fine to leave these plugged in all the time.


I think if you use a smart phone as a phone only, the battery life is respectable, right? (I have no personal experience with the current generation of smart phones.) In contrast, a "dumb phone" has no option of using smart features.
