If you’re looking to extend your talk time (or, more realistically, your browsing and gaming time), then Mophie is one of the best places to start looking. Yesterday, they announced their latest Juice Pack Air case for iPhone 4. It’s a relatively slim battery case that extends your battery life and protects your iPhone 4 from minor bumps and scratches.
The Mophie Juice Pack Air for iPhone 4 is pretty similar to older models. This one blends right in with the design of the iPhone 4 and newer Apple gear. It’s a silver plastic case with a black back. Inside of the case is a 150mAh battery that can extend your 3G talk time to 6 hours or your 3G browsing time to 5 hours. And it stays relatively slim at .68 inches thick. That’s .07 inches thinner than the 3GS version.
Like other cases, the Juice Pack Air won’t obstruct your buttons or ports…well, except the dock connection. That’s necessary for charging, and you can still power up and sync over a standard USB cable. Yes, you’ll need something different than the standard iPhone dock connector, but it comes with one. After it’s done charging, there’s an On/Off switch to control battery backup. Often, the best way to use this kind of a case is to let the external battery die, then take it off and let the iPhone 4 go alone with its internal battery.
The Mophie Juice Pack Air for iPhone 4 is available now for $80.
