android14 自动休眠代码逻辑 ios14自动休眠

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2022年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。
