 # @ohos.resourceschedule.deviceStandby（设备待机模块）
-当设备长时间未被使用或通过按键，可以使设备进入待机模式。待机模式不影响应用使用，还可以延长电池续航时间。通过本模块接口，可查询设备是否为待机模式，以及使应用灵活申请开启或关闭待机模式。
+当设备长时间未被使用或通过按键，可以使设备进入待机模式。待机模式不影响应用使用，还可以延长电池续航时间。通过本模块接口，可查询设备是否为待机模式，以及使设备某个应用能避免纳入待机资源管控、解除避免资源管控。
 
 >  **说明：**
 > - 本模块首批接口从API version 10开始支持。后续版本的新增接口，采用上角标单独标记接口的起始版本。
