MacBook pro 盒盖有休眠耗电，而且是大量耗电。查看电池偏好设置，只看到阶梯状的耗电量，并且找不到到底是哪个软件进程在消耗电量。
打开终端，输入以下命令，查看到底是谁！在休眠的时候唤醒Mac，做一些偷偷摸摸的小动作。
pmset -g log|grep -e " Sleep " -e " Wake " -e "Wake Request" -e "WakeTime"
进程1：活跃得动态头像 以及Wi-Fi

这是macOS Monterey系统的问题，你可能设置了动态的头像，系统在休眠的时候动态头像时不时唤醒Mac。
解决办法：换一个静态普通头像 ，休眠前关闭Wi-Fi
进程2：活跃的蓝牙

休眠中蓝牙唤醒Mac的问题及其明显，耗电量也是巨大，亲测有30%电池电量消耗。蓝牙不断的扫描设备，也是Monterey系统的bug，苹果官方说在4月要升级改进，目前不确定是否改进了。由于个人原因不能进行升级测试，对了，我的系统是Monterey 12.3。你们可以升级试一下，评论区告诉我好用吗。
解决办法：盒盖休眠前手动关闭蓝牙
还有一些会影响休眠耗电问题需要注意
-系统偏好设置：关闭时间机器自动备份-系统偏好设置-电池：关闭唤醒以供网络访问-系统偏好设置-电池：电能小憩功能可让某些 Mac 电脑即使在睡眠时也可以保持最新状态。当 Mac 进入睡眠状态后，电能小憩功能会定期激活以更新信息。关闭电能小憩（有的系统没有此功能）断开与外部设备关联在终端中修改电脑休眠模式，由于博主没用过，可以查看下面原文链接（或者搜索：修改Mac电脑休眠模式）Mac 篇一：Mac合盖休眠掉电快？关掉这个设置再试试_超极本_什么值得买升级系统或者降级到big Sur有用的链接/@hinddeep.purohit007/fixing-the-dreaded-battery-drain-issue-on-a-sleeping-mac-6e153e464b13
