I want to remove battery charging symbol from the status/notification bar? (near to digital clock).

As I have installed the Android AOSP on a development board which has not battery, so want to remove the battery related symbols/icons from quick settings and notification bar.

By changing in file - frameworks/base/packages/SystemUI/res/values/config.xml

<string name="quick_settings_tiles_default" translatable="false">

<string name="quick_settings_tiles_stock" translatable="false">

battery symbol has been disappeared from quick settings, but it is still there in the notification bar.

Where else I have to make changes to remove battery symbols completely? Let me inform, that I am not an Android core JAVA developer.

Any suggestions.
