I seem to have found the problem. I'm just not sure what the easiest solution is, I hope you can help.
I seems that the stock battery gauge isn't set to do 1% increments. So it only updates the 1% gauges in the same increments that it's normally set to, which seem to be 20%. Now the circle mod gauge has 1% increments, so I could foreseeably change all of the file names for the "car" stye gauge to be the same as the circle gauge and reload the systemui and framework apk's to have the new images. I could make a linux script that wouldn't be terrible to do this...
But what I'd rather do is just add a new battery gauge with the images I want. What I'm not sure about is how easy this is to do. Or even how to go about it. Would I have to edit xml files and such things that I know nothing about in order to add a new battery gauge that would be selectable in the system menu? I'm guessing I would.
So my question is, should I just rename the battery files for the gauge I want to be the same as the CircleMOD files and reload system and framework so that circle mod is my prefered gauge? Or should I dive into trying to add a new battery meter completely?
Thanks for all of your help!
