>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: Android
>    Affects Versions: 2.9.0

> The meaning of the Battery "level" in Cordova is a charge *percentage*. 
> Ref http://cordova.apache.org/docs/en/2.9.0/cordova_events_events.md.html#batterylow
> But the Battery EXTRA_LEVEL is not a percentage. It's just a number in the range 0 to EXTRA_SCALE
> Ref http://developer.android.com/reference/android/os/BatteryManager.html#EXTRA_LEVEL
> So the battery level calculation should be something like:
> {code}
> int level = batteryIntent.getIntExtra(android.os.BatteryManager.EXTRA_LEVEL, 0);
> int scale = batteryIntent.getIntExtra(android.os.BatteryManager.EXTRA_SCALE, 100);
> int percent = 100 * level / scale;
> obj.put("level", percent);
> {code}
