Battery Magic Pro for iPhone has features like charge alert and power sync. Now you can charge your battery using either your iPhone or iPod and hear a pleasant sounding alert when the battery is fully recharged. You can turn on the alert in repeat mode or just hear it once, your choice. It also includes many features and functions including the easy-to-use scrolling wheel menu that enables you to get all of your important battery status presented in hours, minutes and percentages. Power users will appreciate the accuracy of how much battery juice they will have to complete their game play, talk time, web browsing, or any other iPhone and iPod touch application you would like to run before your plane lands.
