To remove the battery icon the AWESOME way, we need to do a bit more work.

First, decompile your original SystemUI.apk again and change the battery text in status_bar.xml as before. But, this time, don't edit the battery icon line. Instead cut and paste it to above the battery text line. Like this:

Save and then edit stat_sys_battery.xml in the drawable folder. Change it from:

<?xml version="1.0" encoding="utf-8"?>
<level-list
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/stat_sys_battery_0" android:maxLevel="4" />
<item android:drawable="@drawable/stat_sys_battery_15" android:maxLevel="15" />
<item android:drawable="@drawable/stat_sys_battery_28" android:maxLevel="35" />
<item android:drawable="@drawable/stat_sys_battery_43" android:maxLevel="49" />
<item android:drawable="@drawable/stat_sys_battery_57" android:maxLevel="60" />
<item android:drawable="@drawable/stat_sys_battery_71" android:maxLevel="75" />
<item android:drawable="@drawable/stat_sys_battery_85" android:maxLevel="90" />
<item android:drawable="@drawable/stat_sys_battery_100" android:maxLevel="100" />
</level-list>

to:

<?xml version="1.0" encoding="utf-8"?>
<level-list
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/no_battery" android:maxLevel="100" />
</level-list>

Then change stat_sys_battery_charge.xml from:

<?xml version="1.0" encoding="utf-8"?>
<level-list
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/stat_sys_battery_charge_anim0" android:maxLevel="4" />
<item android:drawable="@drawable/stat_sys_battery_charge_anim15" android:maxLevel="15" />
<item android:drawable="@drawable/stat_sys_battery_charge_anim28" android:maxLevel="35" />
<item android:drawable="@drawable/stat_sys_battery_charge_anim43" android:maxLevel="49" />
<item android:drawable="@drawable/stat_sys_battery_charge_anim57" android:maxLevel="60" />
<item android:drawable="@drawable/stat_sys_battery_charge_anim71" android:maxLevel="75" />
<item android:drawable="@drawable/stat_sys_battery_charge_anim85" android:maxLevel="90" />
<item android:drawable="@drawable/stat_sys_battery_charge_anim100" android:maxLevel="100" />
</level-list>

to:

<?xml version="1.0" encoding="utf-8"?>
<level-list
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/stat_sys_battery_charge_anim100" android:maxLevel="100" />
</level-list>

Still with me so far? Don't worry, we're nearly done.

Now all you need to do is extract stat_sys_battery_charge_anim100.png from the icons.zip attached to this post and copy it into your applicable drawable folder. For my fellow Z users, you need to copy it into drawable-xxhdpi.

Next, extract no_battery.png from the zip and copy it into your drawable-nodpi folder.

Save your edited xml files, recompile and so on.

And this is the result:

And here's how it looks when charging:

And there's only one word to describe this... AWESOME!!
