配有Retina显示屏的MacBook Pro 13在盖子关闭的情况下过夜消耗10％的电池，这是正常的吗？

我差不多一个月前买了一台MacBook Pro 13 Retina。与朋友交谈时，他告诉我这台电脑在关闭盖子并禁用“Power Nap”的情况下过夜使用10％电池是不正常的。

这是真的吗？如果确实如此，保修是否涵盖了这个问题？

这是我从pmset -g log | grep ' Wake '命令中得到的日志

更新：
我到目前为止尝试的内容：
1。将操作系统从El Capitan更新到Sierra
2.重新安装操作系统3.将
我的路由器从D-link更改为Cisco
4.重置SMC和PRAM
5.将PC安装在安全模式下

更新2：
在与Apple客户服务交谈后，他们也告诉我：
1。删除一个名为Dropbox的程序。
2.从Safari中删除扩展，在我的例子中，它是一个添加块。
3.尝试创建测试用户以查看电池是否仍然耗尽。

更新3：
几次与Apple客户服务人员交谈后，他们无法查明问题，因此他们告诉我检查硬件问题。我的学校考试结束后我会做的...

即使在这些步骤之后，问题仍然存在。

问题是当MacBook Pro处于睡眠状态时，macOS会继续检查更新（包括电子邮件，软件，新闻等）。这意味着它可以非常快速地启动和运行，但这也意味着您的电池电量下降。

要解决此问题，您可以告诉MacBook Pro在睡眠时断开与Internet的连接。

为此，您需要将设置tcpkeepalive设置为0。

打开终端并输入：

sudo pmset -b tcpkeepalive 0

输入sudo的密码后，它会向您发出警告，提示某些功能可能无法正常工作。这很好，它只是在睡眠期间禁用Internet访问。

您可以通过运行来检查它是否设置正确：

pmset -g

哪个应该显示“ tcpkeepalive 0”

当然，您可以通过运行来随时撤消它：

sudo pmset -b tcpkeepalive 1

简单！

注意：您还可以强制你的Mac没有连接到互联网时，它睡着了，即使连接到电源，如果你喜欢：sudo pmset -a tcpkeepalive 0。（我个人不介意，只要它不使用我的电池，所以-b对我来说没问题。）

另请注意：结果pmset -g将根据您运行命令时 MacBook Pro是否已连接电源而有所不同。它将反映当前的 tcpkeepalive设置，具体取决于当前的电源情况。

之前我遇到了同样的问题，我的MBP 2015电池正在慢慢消耗，但是当我不经常使用它时，这引起了很大的痛苦。这种方法对我帮助很大; 现在，我可以带着20％的费用购买我的Mac并完成我的一天。MacBook Pro 2015和之前的MacBook Pro型号之间存在显着差异。您可以通过此命令行检查这些设置;

ioreg -l | grep IOPlatformFeatureDefaults

你的mac上的输出就是这样的;

{ “TCPKeepAliveDuringSleep”=是 “DNDWhileDisplaySleeps”=没有， “TCPKeepAliveExpirationTimeout”= 43200， “NotificationWake”=是}

要使MBP像旧版本一样深入睡眠，首先应将计算机重新启动到恢复模式。要做到这一点，你应该重新启动你的Mac并按住CMD + R直到你听到启动声音。在那个打开的终端之后输入这个;

csrutil disable

然后重新启动MacBook。转到此目的地，您可以通过右键单击 - >显示包内容/System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/PlugIns/X86PlatformPlugin.kext/Contents/Resources来访问kext文件内部

找到您的董事会ID：

ioreg -l | awk '/board-id/{print $4}' | sed 's/[<">]//g'

通过文本编辑器打开<your_board_id> .plist（例如Mac-E43C1C25D4880AD6.plist）文件并像这些一样编辑这些设置;

<key>TCPKeepAliveDuringSleep</key>
<false/>
<key>NotificationWake</key>
<false/>
<key>DNDWhileDisplaySleeps</key>
<true/>

TCPKeepAliveDuringSleep在睡眠时保持MacBook连接打开，因此它可以保持Wifi连接。NotificationWake随机唤醒你的Mac以检查通知，尤其是使这个错误。DNDWhileDisplaySleeps的意思是“请勿打扰睡觉”; MacBook在睡着时会受到通知的干扰。

我个人认为，这个过程应该由每个2015+ MacBook用户完成，因为MacBooks不是响铃的手机。Apple应该已经为此做了一个切换按钮。

不要忘记再次启用系统完整性保护。您应该重新启动进入恢复模式并在终端上键入“csrutil enable”并重新启动。

更新：据报道，这不再适用于最新版本的macOS。有关详细信息，请参阅此MacRumors文章。

这不正常，但至少在日志中非常清楚，正在处理ACK数据包，并且您的无线网卡正在阻止笔记本电脑正常睡眠。日志与开发人员笔记一致，可用于使计算机唤醒的事件，并记录它“慢”，到目前为止，正如OzzieSpin在上面的评论中所说，您的计算机正在异常唤醒 - 无法（如还有上面讨论过的几条评论，它试图连接一些东西） - 例如验证，蓝牙关闭， 没有任何方式连接到电脑，包括SD卡插槽，电脑没有连接对于任何类型的服务器，例如smb shared-drives或ldap，并且根本没有程序运行（是的，包括Safari或Drop Box，这两者都可能导致这些symtoms），包括你不期望的那些（参见参考资料）例如，您在“系统偏好设置”中的“ 用户和组 ”下的“启动”项目，以及$ USER / Library / LaunchAgents）。请你发布输出sudo ifconfig？

您可以通过查看Apple网站上几乎相同的帖子进行验证，其中OP在收到Apple支持后返回，并确定问题是不兼容的无线接入点或路由器，并且路由器上的固件升级解决了这个问题，显然。 该链接以及此链接包含您需要检查的长列表，直接来自Apple，以及

如果你单独走过那些帖子后你的问题没有消失，我会感到惊讶。

继续前进，通常的操作，如果我没有看到这些帖子将重置您的SMC（模型，这里的说明）和PRAM。将笔记本电脑插入墙上，关闭所有应用程序/保存数据，然后按住Cmd+ Opt+ Shift并按电源按钮。屏幕应立即关闭。然后，等待10秒钟。接下来，当它关闭时，按住Cmd+ Opt+ P+ R然后按电源按钮。继续按住这些按钮，直到听到提示音，屏幕亮起，然后再次关闭。在确保您关闭服务（请参阅上面的链接），然后重置硬件之后，您可以将计算机作为问题的唯一来源。

作为一个侧面说明，由于Sierra刚刚问世，那么根据您的情况，您可能会等到错误升级之前稍微解决。

这是一个对我有用的侵入性较小的解决方案：在MacBook休眠时启用“请勿打扰”。
