okay, this is the link of the one youre supposed to download:

then you need to flash it like an update.zip (dont change the name of the file). after the phone reboots when you install, you HAVE to change the battery indicator style to "Percentage" or else there will be a white block that shows up inside the circle. if youre at 90%, the circle should be BLUE with a 90% in the middle of it, it'll turn green around 60-65%, yellow around 35-40%, and red around 15-20%.
note: if you have a theme that changes the colors of the icons or battery already, that will override the colored icons from this battery file. if you are using a theme that changes them, try switching to the stock theme, then flash this.
