Android 可以通過BroadcastReceiver來獲取電池信息改變的廣播（ACTION_BATTERY_CHANGED），從而獲取到相關的電池信息。

電池信息，及其對應的相關常數（參考網址：http://blog.sina.com.cn/s/blog_5d2e69770102vh59.html）

電池信息	類型	備注
status	int	取得電池的狀態，返回的狀態類型由 android.os.BatteryManager 類定義的常量所決定，包括：
		電池充電狀態（ BATTERY_STATUS_CHARGING ）
		電池放電狀態（ BATTERY_STATUS_DISCHARGING ）
		電池滿電狀態（ BATTERY_STATUS_FULL ）
		電池不充電狀態（ BATTERY_STATUS_NOT_CHARGING ）
		電池未知狀態（ BATTERY_STATUS_UNKNOWN ）
health	int	取得電池的健康狀態，返回的狀態類型由 android.os.BatteryManager 類定義的常量所決定，包括：
		電池損壞（ BATTERY_HEALTH_DEAD ）
		電池健康（ BATTERY_HEALTH_GOOD ）
		電池過熱（ BATTERY_HEALTH_OVERHEAT ）
		電池電壓過大（ BATTERY_HEALTH_OVER_VOLTAGE ）
		未知狀態（ BATTERY_HEALTH_UNKOWN ）
		未明示故障（ BATTERY_HEALTH_UNSPECIFIED_FAILURE ）
present	boolean	判斷當前是否存在電池
level	int	取得電池的剩余容量
scale	int	取得電池的總容量，通常為 100
Icon-small	int	取得電池對應的圖標 ID
plugged	int	連接的電源插座類型，返回的狀態由 android.os.BatteryManager 類定義的常量所決定，包括：
		USB 電源（ BATTERY_PLUGGED_USB ）
		交流電電源（ BATTERY_PLUGGED_AC ）
voltage	int	取得電池的電壓
temperature	int	取得電池的溫度，單位是攝氏度
technology	String	取得電池的類型

獲取電池信息的步驟：

（1）創建BroadcastReceiver，用於結束電池信息變化的廣播

private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {  
    @Override  
    public void onReceive(Context context, Intent intent) {  
        String action = intent.getAction();  
        if (action.equals(Intent.ACTION_BATTERY_CHANGED)) {  
           //TO GET BatteryInfo
        }

(2) 重寫onResume()方法，獲取IntentFilter對象，並注冊BroadcastReceiver

	protected void onResume() {
		IntentFilter filter = new IntentFilter();  
		filter.addAction(Intent.ACTION_BATTERY_CHANGED);  
		registerReceiver(mBroadcastReceiver, filter);
		super.onResume(); 
	}

（3）程序在后台的時候取消注冊BroadcastReceiver

	protected void onPause() {
		unregisterReceiver(mBroadcastReceiver); 
		super.onPause();
	}

實例：

public class GetBatteryInfo extends Activity {
	private static final int REFRESH_TIME = 1;
	private static boolean runtime=false;
	private TextView mStatus_BatteryInfo;
	private TextView mPlugged_BatteryInfo;
	private TextView mLevel_BatteryInfo;
	private TextView mScale_BatteryInfo;
	private TextView mVoltage_BatteryInfo;
	private TextView mTemperature_BatteryInfo;
	private TextView mTechnology_BatteryInfo;
	private TextView mHealth_BatteryInfo;
	private TextView mRuntime_BatteryInfo;
	private TimeThread timeThread;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		InitView();
	}
	
	private void InitView() {
		mStatus_BatteryInfo=(TextView)findViewById(R.id.status_BatteryInfo);
		mPlugged_BatteryInfo=(TextView)findViewById(R.id.plugged_BatteryInfo);
		mLevel_BatteryInfo=(TextView)findViewById(R.id.level_BatteryInfo);
		mScale_BatteryInfo=(TextView)findViewById(R.id.scale_BatteryInfo);

		mHealth_BatteryInfo=(TextView)findViewById(R.id.health_BatteryInfo);
		mRuntime_BatteryInfo=(TextView)findViewById(R.id.runtime_BatteryInfo);
	}

	@Override
	protected void onResume() {
		IntentFilter filter = new IntentFilter();  
		filter.addAction(Intent.ACTION_BATTERY_CHANGED);  
		registerReceiver(mBroadcastReceiver, filter);
		startTimeThread(timeThread);
		super.onResume(); 
	}
	
	@Override
	protected void onPause() {
		stopTimeThread(timeThread);
		unregisterReceiver(mBroadcastReceiver); 
		super.onPause();
	}

	private String msToTime(int milliseconds ){
