Enable Numeric Battery in firmware 3.0 Manually

Firmware 3.0 has a feature in it that allow you to enable/disable a numeric battery percentage on the status bar of the iPhone. Apple, decided to make this feature only available to the iPhone 3GS and not the 3G. Below is how to enable the numeric battery on the iPhone 3G and yes it works.

1. Connect to your iphone 3G using WinSCP (SSH)
   
2. Before doing anything, backup the file called com.apple.springboard.plist located in /var/mobile/Library/Preferences/ and then copy it to your computer.
   
3. Download pledit.zip that is attached and extract it to the same folder as your file called com.apple.springboard.plist
   
4. Run Pledit.exe and open com.apple.springboard.plist
   
5. Find the following:
   
   

     <key>SBReorderCount</key>
     <integer>2</integer>

6. Add the following key under it
   
   

     <key>SBShowBatteryLevel</key>
     <true/>

   if it already exists, then change <false/> to </true>
   
7. Save the file com.apple.springboard.plist in PLedit.exe and exit.
   
8. Using WinSCP or SSH, copy com.apple.springboard.plist from your computer to /var/mobile/Library/Preferences/ on your iPhone 3G and overwrite the original file.
   
9. Execute the following command from WinSCP or from a SSH terminal window:
   

   killall SpringBoard

That's it. You can't enable and disable the numeric battery indicator like you can on the the iPhone 3GS in the Settings->General->Usage menu, but it does displays a numeric battery indicator on the status bar of the iPhone 3G.

Note: If you don't want to go through this hassle, you can install SBSettings in Cydia and enable the numeric battery. SBSettings replaced BossPrefs. BossPrefs still installs in 3.0, but the numeric battery no longer works and it messes up the order of your application icons.

I know an easier and faster way to enable that feature and even the switch in Settings->General->Usage
Just add

        <key>gas-gauge-battery</key>
        <true/>

to M68AP.plist in /System/Library/CoreServices/

Giabar's mod allows you to enable or disable the numeric battery using the Settings-> General-> Usuage ->Battery Percentage [ON / OFF] menus on your iPhone 3G. Below are instructions that on how to do this:

Yeah, you can do this through Cydia without SSH. Download and install asBattery (only tested on the iPhone 3G). This also gives you the ON and OFF switch within Settings.

[reddawg]

AsBattery is definately much easier to install and works as you described, but I found that it seemed to drain my battery faster than it should. After uninstalling it and using the above mod, my battery isn't draining as fast.

I can't find asbattery on cydia what source needs to be installed?

Thanks

Anyone know how to get old style display? Replace the whole battery with just number... 1~100. No % symbol. Touch to switch between battery and number.

I did the % battery for my iphone 3g, and it works, however after doing this my phone seems to drain a lot quicker. Is anyone else noticing this, or is it only me?

The battery doesn't seem to drain faster with the numeric battery. I +1 to Kcolraw. I HATE THE % symbol and the battery icon! So much space taken up just to tell me the battery status!!! I want the old style numeric battery back!! Anyone? Please?

[giabar]

To remove % I think we should look at PNGs in system>library>coreservices>springboard.app
Unfortunately I don't have the possibility to verify it by myself 'cause I cannot convert iPhone's PNG with my computer

Isn't it easier to just enable it through SBsettings?

definitely easier. Just a simple toggle in the Extra Options menu on SBSettings.

I am still looking for a way to either remove the battery icon or the "%" so i get the old clean look of numeric battery...

[twowaymonologue]

Hey all, like you I've been pissed that I can't have the battery OR the percentage.

I SSHed into /System/Library/CoreServices/SpringBoard.app as per the suggestion of a previous poster. There I found numerous .png files which I wasn't able to view so I just started deleting them with a sort of educated randomness. I found that I could make the '%' symbol disappear if I deleted "Default_Percent_%.png" and "FSO_Percent_%.png".

At least it no longer has to take up as much space on the right hand side of the taskbar.

Hope that helps.
