Double Your iPhone’s Battery Charge

Add this to the list of things we need; the Mili PowerSpring 4 a extended battery/case shipping today, for $85 on Amazon.

Is the latest in a series of iPhone 4 battery packs. The Mili promises to double your battery life, all thanks to its 1600mAh capacity Li-Pol battery. It also claims to be world's thinnest.

With the PowerSpring 4 Extended Battery, the iPhone 4 can have up to 36 hours of audio playback, 10.6 hours of video playback, 6 hours of talk time, and standby time of 360 hours.

As with almost every other case/battery pack it also succeeds in making your iPhone 4 look like and iPhone 3GS. We think it's a plot.
