我前段时间也遇到同样的情况，后来在坛里搜索帖子解决了
关闭 tcpkeepalive

1. 去天才吧检测下，说不定有硬件或者软件设定的问题
2. 看下床底下有没有人，半夜出来用 mac...

@fjian 严重怀疑第二点是真实存在的，毕竟 V 友不骗 V 友

我遇到过一样的问题,后来发现是一直开着那个系统自带的 garbage 录音软件, 退出就好了

调查了一下, 大概是这个原因 https://truxton2blog.com/soundflower-audio-device-cpu-high-usage/

@kafkaonsea @arcaitan 谢谢, 这两个我都试一下, 观察几天看看效果

把插在电脑上的 USB 社保拔掉。比如 SD 卡扩展存储一类的。这个东西会阻止休眠进入睡眠。导致跑光电。

关掉 tcpkeepalive ，盒盖前断开所有外设，包括蓝牙键盘、鼠标，禁止网络唤醒，重启不正常占用 CPU 的应用（例如企微启动过会议，微信开过小程序，关掉音乐 App ）

我没有接任何外设显示器之类的, 和这些无关, tcpkeepalive,powernap 原先设定是 1, 感觉关系应该不大, 1 代表接电源才启用, 我这个是没接电源就耗电的, 反正这两个先设成 0 试试

倒是那个音频的东西是有可能的, 通过 pmset -g assertions 能看到 PreventUserIdleSystemSleep 是 1, 是由火狐进程触发的 BuiltInSpeakerDevice 的 preventuseridlesleep, 退出火狐就没了, 还有之前也装过 blackhole 的虚拟声卡, 现在我也卸了

该做的都做了, 就看会不会复发了

活动监视器的能耗看看？什么软件能耗比较高？

昨天晚上观察了一下, 问题依旧, 早上起来只剩 50%电, 观察活动监视器的能耗没有结论, 因为这个就像是普通的唤醒电脑的样子, 都是一些正常的 APP 的待机能耗使用, 整个看上去就像是半夜 2 点电脑被唤醒打开, 然后 APP 正常待机工作的感觉, 但是实际上是全程不插电, 没有任何外接, 合盖的情况下发生的, 完全搞不懂了, 看日志的话, 只能看到是 0 点的时候进入睡眠, 但是只计划睡眠 2 个小时, 然后两个小时后 DarkWake from Deep Idle, 时间是 6 小时, 反正搞不懂这些计划安排是怎么来的, 头大

用过一些第三方的电源可能导致主板上部分电容损坏，导致即使关机都会一直掉电

这个问题我当年买 18 款 mbp 的时候就遇到过了，没用过第三方电源，也没外接任何设备，突然某一天就出现了这种情况，看日志和你非常类似。重置、重装系统都没解决，最后是通过在 GitHub 上找了个脚本，合盖后自动关闭蓝牙和 Wi-Fi 解决了。

经过几天研究, 可能搞定了, 主要还是靠 pmset -g log 分析日志, 看 WakeRequest 都是些什么东西

一开始是 CSPNEvaluation, 反正是跟 PowerNap 有关的, 想办法改配置文件禁用掉了, 不行

后来是一些 Scheduled power events, 用 sudo pmset schedule cancelall 全部取消掉, 还是不行

再后来发现第二天所有的计划任务又重新冒出来了, google 之后, 先全部 cancel 掉, 然后 sudo chflags schg /Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist 把配置文件设为只读, 貌似可以了

现在过去 2 天都没有半夜耗电的毛病了, 感觉差不多应该是好了, 真是艰难啊
