MyBatteryLife

Here is a great battery app I found on the App Store. As you open the app, this is the graphic that shows up. It has a lot of information available to the iPhone user. It has the title of the app, myBatteryLife at the top. Beneath that is the percentage of how much battery is left. In this case there is 95% left. And then below that percentage, there are times in hours and minutes for Talk Time, Internet on 3G, Internet on Wi-Fi, Video Playback, and Audio Playback. On the right side of the screen is a very neat neon blue battery showing how much "juice" your iPhone has left.
I have really enjoyed using this app. It is great for my long trips in the car when I want to know how many more movies I can watch or how many more games of PaperToss I want to get in. This is also great for you twitter addicts who constantly want to know how much more time they have before they have to find a computer! The only downside is that the myBatteryLife app doesn't appear to be 100% accurate. It is believed that the Apple only allows these apps to show the percentage to within 5% of the truth. For any avid gamer, business man, or tweeter, this is the battery info app for you! Check it out in the App Store for $0.99 : D
