以我的ST18i国行4.0.2.A.0.62系统为例。
一、首先准备所需工具：
① 配置Java环境，然后下载“apktool.jar”“aapt.exe”，这两个文件放在同一个文件夹，例如“C:\ApkTool”
② 用RE管理器从手机“/system/framework”中提取“framework-res.apk”文件也放在这个目录
二、CMD进入“C:\ApkTool”目录，并加载所需框架：
CD \ CD ApkTool java -jar apktool.jar if framework-res.apk
三、解包“framework-res.apk”得到“framework-res”文件夹：
java -jar apktool.jar d framework-res.apk
四、替换“\res\drawable-hdpi”目录下的电量图标为新的“stat_sys_battery_0.png ~ stat_sys_battery_100.png”。
五、修改“\res\values\public.xml”文件：
将如下代码：
<public type="drawable" name="stat_sys_battery_0" id="0x0108044f" />
<public type="drawable" name="stat_sys_battery_10" id="0x01080450" />
<public type="drawable" name="stat_sys_battery_100" id="0x01080451" />
<public type="drawable" name="stat_sys_battery_15" id="0x01080452" />
<public type="drawable" name="stat_sys_battery_20" id="0x01080453" />

<item android:drawable="@drawable/stat_sys_battery_100" android:maxLevel="100" />
七、将“framework-res”文件夹打包成例如“rrr.apk”：
java -jar apktool.jar b framework-res rrr.apk
八、将新的电量图标及修改得到的文件替换到原来的“framework-res.apk”文件中：
① 将WinRAR的默认压缩方式设为“存储”。
② 将新的电量图标替换到原来的“framework-res.apk”中去。
③ 提取“rrr.apk”中的“resources.arsc”及“stat_sys_battery.xml”文件，替换到原来的“framework-res.apk”中去。这样就得到了新的“framework-res.apk”文件。
九、放回手机：
① 用RE管理器将新的“framework-res.apk”放入手机“/system”目录，修改权限为“第一行勾选前面两个，第二行只勾选第一个，第三行只勾选第一个”
② 用RE管理器将修改好权限的新的“framework-res.apk”移入手机“/system/framework”中，重启手机即可。
