This is unquestionably correct. I compensate by having several different methods of recharging available (car 12V outlet, laptop, LiPo rechargeable battery in my laptop or hiking bag, belt case LiPo charger, 2xAA recharger in BOB). The benefits of a smart phone to me vastly outweigh the battery life.

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 all of Mophie's batteries are LiPo, and LiPo batteries are indeed fine to leave plugged in all the time.
