总有人抱怨Mac更新至10.14以上系统后，待机耗电问题严重。最近小编也遇到了这个问题：明明充满电后合上盖子，第二天电量就掉了七八成，有时甚至更多。So，我们该如何解决这个问题呢？小编来分享两个实用的Mac设置小技巧，帮助大家缓解待机耗电情况。 1. 调整节能设置 在系统偏好设置中，找到“节能”选项： •关闭显示器时间设置：分别在电池和电源适配器选项中，将关闭显示器的时间段拉短。这样可以减少显示器亮度时间，从而降低电池耗电速度。 •禁止自动进入睡眠：取消“当显示器关闭时，防止电脑自动进入睡眠”的选项。这可以避免电脑在不需要时过早进入休眠状态，从而减少能耗。 2. 设置勿扰模式 在系统偏好设置中，找到“通知”选项： •启用勿扰模式：在勿扰模式设置中，勾选“当显示器进入睡眠状态时启用勿扰模式”。这样可以在电脑进入睡眠状态时阻止来电和通知的干扰，同时减少后台应用程序的活动，进一步节约电量。 通过以上两个设置，您可以有效地减少Mac在待机状态下的耗电量，提升电池的续航时间，让您的MacBook使用体验更加顺畅和省电。
