代码如下：

   private void getSystemBattery(Context context) {
        int level = 0;
        Intent batteryInfoIntent = context.getApplicationContext().registerReceiver(null,
                                                                                    new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
        level = batteryInfoIntent.getIntExtra("level", 0);
        int batterySum = batteryInfoIntent.getIntExtra("scale", 100);
        int percentBattery= 100 *  level / batterySum;
        Log.i("手机当前电量------"+percentBattery);
    }

调用方式：

getSystemBattery(this);
