检索Android中的电池电量消耗

Question

我已经看到一些应用程序显示电池消耗的mV /小时数。有没有办法检索该信息？或者那些程序定期读取ACTION_BATTERY_CHANGED意图，记录电压电平并计算梯度？<​​/ p>

获取电池信息

private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver()  {
  @Override
  public void onReceive(Context arg0, Intent intent) {          
     int level = intent.getIntExtra("level", 0); 
         System.out.println("battery level" + level);            
  }
};
