just curious as to why you are rooted as a newbie? I hope you know why your are rooted. There are many apps in the market that show battery life as a percent. I use battery widget. I like to know exactly how much I have left, and that little indicator at the top is worthless, and I don't want to have to open my settings to check. It's free, and it's a widget not an app, so when you download it, you will not find it in your apps. You have to long press the screen, add widget, and it should be the second or third one down.
