Apple Smart Battery Case Review: iPhone Battery Life Nearly Doubled - WSJ

From a review of Apple's first iPhone case + external battery + case-compensating antenna

"After five days of living with the Smart Battery Case wrapped around my iPhone, I no longer feel so powerless. Even better, Apple fixes many of the issues I’ve had with cases over the years. It uses the same Lightning cable as the iPhone to charge, and it tells you how much power is remaining right on the phone’s screen. Besides, the case doesn’t feel like the stuff plastic forks are made of.

There’s just one thing to consider before you buy: With a third-party case, you can get twice as much power for half the cost."
