与MobileSignalController logcat消息相关的高电池消耗(voiceNetType 13至0)

Question

首先，为这个问题提供一些背景：

我位于奥地利的格拉茨，现在我已经有了两年的诺基亚5手机，在过去的5-6个月里，我的电池消耗突然增加，而我身边的行为并没有发生任何真正的变化。突然间，在克罗地亚度假时，我注意到我的电池突然用了1.5至2.5天，而不是我在家时的0.5天。回到家里，我的手机又充电了0.5天.起初，我认为这可能是因为我度假期间手机使用量减少，但在一个月前我在伦敦参加droidcon会议期间，我注意到了同样的行为:不同的国家，较低的电池消耗量；在奥地利，更高的电池消耗量。

MobileSignalController垃圾邮件日志

为了使用logcat获取有关我的问题的一些信息，我立即注意到MobileSignalController组件正在发送关于状态变化的消息，voiceNetType从13变为0。因此，我怀疑高电池使用量可能是由我的服务提供商(称为bob)的一些奇怪行为造成的。

我的同事提出的另一个可能的原因是，当手机在漫游时，某些应用程序的行为可能会有所不同(对我来说，这听起来是合理的，不知道应用程序是否会影响MobileSignalController的行为)。

我想知道的是

由于我对Android操作系统的这部分不太有经验，我想知道是否有人对这部分操作系统有经验，这样的状态变化一般意味着什么，以及这种状态变化背后的原因是什么。

此外，我还感兴趣的是，作为一个程序员，我是否有可能从设置/软件方面来解决这个特定的问题。

为了完整起见，对Logcat输出进行了过滤，以便“移动”

AFAIK，电池排水不依赖于家庭或漫游网络。但这取决于你旅行的时间，假设如果你在旅行，它会像它的开关塔那样耗尽电池，并试图找到信号，并通过查看你的日志--我可以看到，它试图连接到信号，假设信号在某些地方可能变弱了，设备很难找到信号，因为它耗尽了电池，更多的是在探索你的日志时，发现updateTelephony被多次调用，就像在信号参数(mServiceState、mSignalStrength、mDataNetType、mDataState和mSimState)发生变化时用来更新状态的一种方法。下面是框架中的方法，它可以解释同样的情况。

来自框架的updateTelephony方法的源代码：

private final void updateTelephony() {
    if (DEBUG) {
        Log.d(mTag, "updateTelephonySignalStrength: hasService=" + hasService()
                + " ss=" + mSignalStrength);
    }
    mCurrentState.connected = hasService() && mSignalStrength != null;
    if (mCurrentState.connected) {
        if (!mSignalStrength.isGsm() && mConfig.alwaysShowCdmaRssi) {
            mCurrentState.level = mSignalStrength.getCdmaLevel();
        } else {
            mCurrentState.level = mSignalStrength.getLevel();
        }
    }
    if (mNetworkToIconLookup.indexOfKey(mDataNetType) >= 0) {
        mCurrentState.iconGroup = mNetworkToIconLookup.get(mDataNetType);
    } else {
        mCurrentState.iconGroup = mDefaultIcons;
    }
    mCurrentState.dataConnected = mCurrentState.connected
            && mDataState == TelephonyManager.DATA_CONNECTED;
    if (isCarrierNetworkChangeActive()) {
        mCurrentState.iconGroup = TelephonyIcons.CARRIER_NETWORK_CHANGE;
    } else if (isRoaming()) {
        mCurrentState.iconGroup = TelephonyIcons.ROAMING;
    }
    if (isEmergencyOnly() != mCurrentState.isEmergency) {
        mCurrentState.isEmergency = isEmergencyOnly();
        mNetworkController.recalculateEmergency();
    }
    // Fill in the network name if we think we have it.
    if (mCurrentState.networkName == mNetworkNameDefault && mServiceState != null
            && mServiceState.getOperatorAlphaShort() != null) {
        mCurrentState.networkName = mServiceState.getOperatorAlphaShort();
    }
    notifyListenersIfNecessary();
