Mostly works as designed – Battery Box 3-in-1 Review

I like its capabilities, but it didn't deliver on those very well. IPhone 4 doesn't show 3G information. It always say N/A. As for draining the battery; to those who don't understand why you'd want to do it. Lithium ion batteries, like those in you iPhone or iPod need to be drained completely every so often so your device will know where "empty" is at. Otherwise you'll think you've got more battery life than you really do. This doesn't increase the battery life so much as let you really know when it's going to die. ALL batteries deteriorate over time! This app does a good job of letting you know that stats of your phone, but doesn't do a great job actually increasing battery life in this version.
