is there an app that would show the % battery in the battery icon already on the header bar?
If you are saying you want the percentage to show in the notification bar on the top, just search for battery themes in this forum. There are several that include the number.
this function goes by the ROM. If you are Rooted and have a ROM that supports this function, it is possible.
Most rom's will have it in spare parts, or in the system menu under UD settings or Cyanogen settings or in Chevys tool box I think.
It's a set of images. Depending on the ROM there will be 15 or 20 of them for all the various notification states. The numbers are just part of the image. These images can be replaced by a theme or a metamorph script, so if you search for "Battery" and "Percentage" in this forum you can find more than a few I'm sure.
Here's one example: Round Battery Icon
