# @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,可查询设备或应用是否为待机模式,以及为应用申请或取消待机资源管控。
> **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。<br>
## 导入模块
```js
import deviceStandby from '@ohos.resourceschedule.deviceStandby';
```
## deviceStandby.isDeviceInStandby
isDeviceInStandby(callback: AsyncCallback&lt;boolean&gt;): void;
