Mophie has rolled out its new Juice Pack Air battery case for the iPhone 4. Like past Juice Pack Air models, the new iPhone 4 version integrates a rechargeable battery—1500 mAh, in this case—into a protective case with open access to the headphone port, camera + flash, volume buttons, ring/silent switch, and sleep/wake buttons. Mophie claims the new Juice Pack Air offers up to six hours of talk time over 3G, up to five hours of 3G data use, up to 36 hours of audio playback, or up to nine hours of video playback on a single charge. Other features include an integrated LED status indicator, acoustic sound enhancement, and a micro USB port for charging and syncing. The Mophie Juice Pack Air for the iPhone 4 is available now and sells for $80.
