Document Type and Number:
WIPO Patent Application WO/2021/017935
Kind Code:
A1
Abstract:
Provided are a wakelock management method and an electronic device, wherein same relate to the field of electronic devices. The problems of a system failing to sleep for a long time and of the high power consumption of a device due to abnormal lock holding of an application are solved, and the service life of the device is prolonged. The method comprises: a process creating a wakelock, wherein the process comprises a target process, and the target process comprises one or more of the following processes: a process of creating a wakelock by using a file node writing mode, and a process of creating a wakelock by using a mode of calling an interface corresponding to a kernel layer; storing an identifier of the target process in association with the wakelock created by the target process; when it is determined that the target process is exited abnormally, acquiring a wakelock corresponding to the identifier of the target process; and when it is determined that the wakelock corresponding to the identifier of the target process is in an activated state, releasing the wakelock.
