The Mophie Juice Pack Air was an accessory that received praise for the iPhone 3G and 3GS. And while the iPhone 4 has good battery life in general, there are always those who will want more, particularly since – for all the nice, extra access touches for things such as screen orientation lock that we’ve seen in iOS 4.2 – it’s still a hassle to turn off features that drain the battery such as Wi-Fi or Bluetooth.
I was a bit disappointed when I checked out Mophie’s new Juice Pack Reserve and Boost for iPod and iPhone. They felt cheaply made, particularly the dock interface extension which sometimes would stick. butt the company has returned to form with its flagship iPhone charging case. The Juice Pack Air complements and can charge the iPhone 4 from a standard microUSB connector. It also includes a four-LED battery meter.
I still have a few quibbles. I’d like to see the cutouts for the buttons at more of an angle to make them easier to press even though this might sacrifice a bit of protection. Also, the top part of the enclosure can come loose if you are trying to grab it out of a tight pocket. Still, the Juice Pack Air is a great option to provide abbot 70 percent more battery life to he iPhone 4 and a great choice for those who are willing to trade its svelte profile for going the extra mile.
