According to en-SO you should:

 public float getBatteryLevel() { Intent batteryIntent = registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED)); int level = batteryIntent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1); int scale = batteryIntent.getIntExtra(BatteryManager.EXTRA_SCALE, -1); // Error checking that probably isn't needed but I added just in case. if(level == -1 || scale == -1) { return 50.0f; } return ((float)level / (float)scale) * 100.0f; }
