If you have been over to the xda forums recently you could have found the battery mod for Samsung phones on a cm9 ROM. Well I stumbled upon this yesterday and I created a nice little how-to-install it. Its really quicker then what my video shows once you know what your doing. I have downloaded all of the Battery Mods that are available on xda and currently creating a ready-to-flash zip for each one.
If you think the process is to difficult, which its not, then PM me or respond to this and I will send you the one you request. Note I will need the ROM you are using and what version. The battery mod affects your framework and SystemUI. So in your reply or PM just simple say something like this -> Gauge, CM9 Beta 1 4.0.4
The Instructions - by shayne77
Please read all of this, it's not much to read and can save you alot of heartache.
This tool makes modding your current ROMs battery very simple for you. I have tested the ROM I use and that is (ICS) CyanogenMod 9. It should work with Samsung Custom ROM's as well (As long as they are ICS and Deodexed)
The Instructions are very simple...
1) ====== Copy "SystemUI.apk" to the "Input_APKs" folder ======
You can grab this from either; the ZIP archive for your ROM which is located in; \system\app\ of the ROMs zip file or you can copy it off your phone. (Personally, I think it's easier to grab it from your current ROMs flashable ZIP archive)
2) ====== Copy "framework-res.apk" to the "Input_APKs" folder ======
You can grab this from either; the ZIP archive for your ROM which is located in; \system\framework\ of the ROMs zip file or you can copy it off your phone. (Personally, I think it's easier to grab it from your current ROMs flashable ZIP archive)
3) ====== Copy the 204 x Battery PNG images to the "Input_Images" folder ======
If you don't have 204, it won't work. There are 101 to show battery levels from 0 to 100 and there are another 101 to show a charging animation from 0 to 100, There are an addition 2 more to show "charge_animFULL" and "battery_FULL". If you have any of my current battery mod zip's, the PNGs are located in \MORPH\system\app\SystemUI.apk\res\drawable-hdpi\ in the zip archive.
4) ====== Double-click "Mod_my_battery!.bat" and sit back and wait ======
The process should only take a couple of minutes. I will explain in more detail later what is actually happening but, the process is; add current framework for apktool to use, decompile SystemUI, add files needed to show new battery mod in 1% increments, build SystemUI again, create both a flashable zip and also a raw SystemUI.apk. You can use either the flashable zip (as you have been if you have been using my battery mods or if you wish, you can copy the modded SystemUI.apk to your phone.
5) ====== Check the "Output" folder for your newly modded SystemUI ======
In the "Output" folder is either the "Flashable ZIP" file. This is exactly the same as what you would have been using from xda or there is a "Modded APK" file. This is a modded SystemUI.apk file for if you wish to push or copy the actual apk to your phone instead.
