Mophie Juice Pack Air and Exolife

If you’re out and about, be sure that your iPhone is wearing its jacket

If you want to use your iPhone 4 for business, you have to think about battery life. One charge is not sufficient for a full day’s work, especially if the iPhone doubles as your in-car or on-train entertainment.

A couple of years ago, in the era of the iPhone 3, I introduced you to a Michigan company, Mophie, which invented a clever jacket for the iPhone that doubled as a protective case and an add-on battery, doubling, more or less, the phone’s use time.

Since then, battery-filled jackets have become quite common, and when I realised I was running my iPhone 4 down before the end of a work-filled day, I wondered what was out there now. I found two especially good products. One is the Exolife by Exogear, which makes your iPhone thicker front to back, but preserves its head-on profile. The Exolife is OK, but a bit flimsy.

The better iPhone 4 case for me, however, is the new one from, well, Mophie (pictured), which invented the genre. It’s beautifully engineered, with a much better feel in the hand than the Exolife – even though it does turn the iPhone into a big, heavy fellow. Buy both and see which you prefer; it’s the kind of accessory you will lose or leave at home continually, so having two isn’t a bad idea.
