Embodiment 1
[0022] see figure 1 , the power management method provided by Embodiment 1 of the present invention includes the following steps:
[0023] S101. Detect whether the terminal screen is closed;
[0024] S102. If it is detected that the terminal screen is turned off, then detect whether the terminal is in the standby state, and if not, execute S103;
[0025] In Embodiment 1 of the present invention, the following steps may also be included after S102:
[0026] If it is not in the standby state, it is detected whether the power consumption of the system is abnormal, and if it is abnormal, S103 is executed.
[0027] Whether the detection system power consumption is abnormal specifically may include the following steps:
[0028] Collect battery-related parameter information every predetermined cycle, battery-related parameter information includes battery voltage, temperature, power, current, etc.;
[0029] Detect system power consumption value;
[0030] If it is detected that th...
Embodiment 2
[0051] see figure 2 , The power management system provided by Embodiment 2 of the present invention includes: a first detection module 11, a second detection module 12, a third detection module 13, and a log writing module 14, wherein,
[0052] The first detection module 11 is used to detect whether the terminal screen is closed;
[0053] The second detection module 12 is used to detect whether the terminal is in a standby state if it is detected that the terminal screen is closed;
[0054] The 3rd detection module 13, is used for if terminal is not in standby state, then detects the hold and release situation of the lock of all processes in the system kernel layer;
[0055] In Embodiment 2 of the present invention, the third detection module 13 is specifically configured to: determine the lock holding and release status of all processes in the kernel layer by detecting the flag bits set in advance for the locks of all processes in the kernel layer.
[0056] In Embodiment 2...

Abstract
The invention belongs to the field of communications, and particularly relates to a power management method and system and a mobile terminal. The method includes the steps that whether a terminal screen is turned off or not is detected; if the terminal screen is detected to be turned off, whether the terminal is in a standby state or not is detected; if the terminal is not in the standby state, the lock releasing conditions of all processes in an inner kernel layer of a terminal system are detected; lock information which is not released in the inner kernel layer of the terminal system is written into an inner kernel layer log. According to the power management method and system and the mobile terminal, when the terminal is in an off-screen state and not in the standby state, under the condition that abnormal power consumption exists, professional maintenance personnel do not need to go to the scene and use corresponding instructions to examine relevant interface functions, and problems can be quickly located through the inner kernel layer log.
Description
technical field [0001] The invention belongs to the communication field, and in particular relates to a power management method, system and mobile terminal. Background technique [0002] At present, the android mobile terminal will generally enter the standby state when the screen is off and no application program is running, but when a certain process applies for a lock, it will not enter the standby state. If it does not enter the standby state, the system power consumption is generally relatively low. big. [0003] However, when the kernel layer does not enter the standby state in the off-screen state due to applying for a lock and not releasing it in time, the system will consume a lot of power. The user cannot know the reason for the high power consumption of the system. Only by giving it to professional maintenance personnel, who use corresponding commands to view the relevant interface functions, can they locate which process has applied for the lock but has not rele...
