The days are long, and there was a lot of texting and social networking, but the Juice Pack pulled through! Read all the reasons I'd recommend this device— and one reason I wouldn't — after the break.
Mophie sent me the awesome shiny red case to test — one of my favorite colors. While it's understandably heavier than other cases (there is a battery in there, after all), it was still easy to hold, and certainly not too heavy to carry around. In fact, the case gave my phone a nice heft that made it easier to find in my crowded bag. The case charges via USB, so I plugged it into my computer each night before bed, just as I plug in my iPhone to charge. It had a full charge each morning, which was easy to tell by pressing the button on the back of the case to illuminate the indicator lights.
Once my phone was down to a 75 percent charge (here's how to view your iPhone's battery life as a percentage), I turned the Mophie on via a small switch on the bottom of the phone. It started charging instantly, and took less than an hour to reach full charge. Once I was at or close to 100 percent, I switched it off and the Juice Pack became a protective and pretty case.
The (Sort-Of) Bad
Three days of using the Mophie, and three different battery experiences. The first day, the Mophie only lasted about four hours; the second, it lasted six; the third, eight. The key to a lasting battery: switch it off if your phone is fully or mostly charged. Once I started thinking about the Mophie in the same way I think about a charger that plugs into the wall, the battery started lasting longer.
I loved everything technical about the case, but by the end of the third day, the shiny red paint had begun to flake off from the heat — both the hot weather and the heat from my hand. It didn't get especially messy, but the case is now sporting a slightly wrinkled look.
I loved the Mophie Juice Pack Air! During the review I was holding and using my phone a lot, and despite its new, "textured" appearance, I will continue to use it. I'd certainly recommend it for extending your iPhone's life. I would not recommend holding it for long periods of time, using it excessively in hot temperatures, or leaving it out in the sun. But in the end, it did everything I needed it to do, providing battery life for my phone from the first set of the day through Gaga's Bad Romance fireworks.
