How to Show iPhone Battery Meter in Percentage

Other than those prominent features (e.g. video editing, voice control), iPhone 3GS has come with some minor but nice touches. One of them is the battery percentage switch in Settings that allows you to change the battery life indicator to percentage representation.

I’m sure not all of you are using iPhone 3GS or have any plan for the upgrade. But you probably want to use this precise battery meter to show the battery life on iPhone 2G/3G.

In this post, I’ll walk you through and show how you can change the battery indicator to percentage form. And, don’t worry. This guide is not just designed for iPhone 3GS and it applies to all iPhones (to be exact, jailbroken iPhone).

For iPhone 3GS

1. Go to “Settings”

2. Tap General -> Usage

3. You can easily change the battery indicator to percentage by turning ON the “Battery Percentage” option.

iphone3gs-battery-meter

For other iPhone users

I’m not sure why Apple does not release this minor feature to older version of iPhone. But if you have jailbroken iPhone, you can also change to battery percentage with minor tweak.

Tip: If you haven’t jailbroken your iPhone, you can follow this jailbreak guide for iPhone 3.0 (Windows / Mac).

1. Launch Cydia

2. Search for SBSettings and install it

sbsettings-cydia

3. Once you complete the installation, you can launch SBSettings by swiping across the status bar.

Launch SBSettings

4. Tap “More” button in SBSettings

5. Tap “Extras & Options” and turn ON “Numeric Battery”

sbsettings-moresbsettings-extras

6. Click Home button to go back to home screen and you’ll notice that the battery indicator changes to percentage.

As always, leave me comment and let me know if this works for you.

    I am using a JB 3.0 3G, but I cannot search the SBSettings from Cydia successfully; but some other SBSettingstoggles. Pls advise.

    BTW, I did it success when I was in version 2.2 sth.

    Pls help.

      This Simon guy should not give advice on iPhone tech repair. His advice is basic which does solve any real issues. With that said the advice is taken care of by common sense.

    GFreat blog.

    On my jailbroken 2.2 I had the numeric battery which took the place of the graphic one. Do you know if there’s any way to hide the graphic one so that there is more room on the status bar (for weather & status icons)?

    • http://www.simonblog.com Simon Ng

      @davedalus, seems there is no way to hide the graphic battery icon. If you find one sooner or later, do share with me. Thanks.

  • davedalus

    thanks for the response, will let you know if I find one.

  • Titus

    It works well and very impressed.

  • Omaley13

    very nice, tks

  • Jedi

    i have 2.2.1 jailbroken. it worked for me before but now when i toggle it it just shows the number with no percentage symbol or battery icon what happened. or how can i fix it to be percentage symbol, number and icon.

  • Jason

    thanks man. works like a charm

  • davedalus

    Hi Simon, quick update on this. Modmyi have just released a tweak called ‘battery control’. Once installed, it puts a new menu in settings, where the battery percentage and image can both be toggled on/off. It isn’t the touch control we had before to switch between the two, but it does free up the statusbar for weather, RAM etc.

    hth.

    • http://www.simonblog.com Simon Ng

      @davedalus, thanks for your sharing! I will post your tip very soon.

  • roger c.

  • danny

    this worked great, but my batter bar now stays full while only my percentage diminishes. is there a way that both the percentage and the bar diminishes at the same rate? i have 3gs. thanks

  • Tara

    good job like this page really help job welldone

  • Cody

    If you have Ifile or open ssh with winscp , this method is way better than any of the other options , its the official one from apple just hacked onto it by as simple as adding this under

    System/Library/springboard.app/* (look Below for your model) And adding this
    (gas-gauge-battery
    ) under the delay-sleep-for-headset one

    make sure that you hit enter before the true part ….. im confused because i added mine uner M68AP.plist but it saved under N82AP.plist (For iphone 3g)so i would try wither one of those for iphone 3g

    but if your on another device add it under this one

    ************M68AP.plist (iPhone 2G), N82AP.plist (iPhone 3G), N45AP.plist (1st-generation iPod touch), or N72AP.plist (2nd-generation iPod touch).

    if it says malformed line or something like that try it the other .plist that has the same icon ( M68AP N82A ,,thers always other options ones like the official one and one i think is like for jailbreak or something ,,, but idk .

    EMail me if you have any problems:

    Unquestionably believe that which you said. Your favorite reason seemed to be at the net the simplest thing to remember of. I say to you, I definitely get irked while people consider worries that they just don’t understand about. You controlled to hit the nail upon the highest and also outlined out the whole thing without having side effect , folks can take a signal. Will probably be back to get more. Thank you

  • Jasmine

    Worked great thanks :)
