[Q] [help need]How to change battery icon in cm11 topic

I'm using cm11 on my xperia m , trying to change status bar icons . I successfully changed wifi,signal,bluetooth icons by editting SystemUI.apk
. Now i want to change my battery icons, I'd found some battery icons in framework-res.apk, I recompiled & singned the framework-res.apk after replacing those battery icons.I created a flashable zip and flashed with that zip using CWM.But the changes made are not reflected . The battery icons wasn't changed :(.
I think the cm11 battery icons files are not kept in framework-res.apk, settings.apk & SystemUI.apk. help me to locate n change those battery icons
