In the instant messaging on the mobile phone, the change of an IP address is often caused due to the switching of a base station or the problem of network NAT (network address translation) causes that the information of an external network cannot be sent to the mobile phone or the machine of an internal network. Therefore, long connections need to be maintained in a heartbeat mode, and a TCP hole punching mode is used for breaking through the shielding of NAT. However, maintaining a long connection using a heartbeat method necessarily results in increased power consumption, especially on mobile devices. Power consumption has been used as a measure of how good a mobile app application is.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the process of implementing the technical scheme in the embodiment of the present invention, the inventor of the present invention finds that the prior art is as follows: the mobile phone has a sleep function, and once the mobile phone enters the sleep state, the mobile phone cannot send heartbeat and receive messages. Long sleep periods can result in messaging delays. The application CPU must be woken up through the baseband and be able to heartbeat and send and receive messages. The power consumption on the android mobile phone is mainly the use of a screen and a CPU. Frequent waking of the CPU necessarily results in an increase in the power consumption of the app. Further, the inventor of the present application finds that the prior art ignores the condition that the CPU wakes up under normal use, and repeatedly wakes up the CPU, thereby consuming electric power; the optimization condition under the condition that a plurality of instant messaging devices of the android exist mutually is ignored, and each application in a plurality of applications wakes up the CPU to receive and send messages at regular time, so that the power consumption of the mobile phone is greatly increased.

The inventor of the present application, in order to improve the above technical problems, invented the technical solutions provided in the embodiments of the present invention. Embodiments provided in embodiments of the present invention will be described in detail below with reference to specific examples and the accompanying drawings.

Referring to fig. 2, an embodiment of the invention provides a power saving method applied to an electronic device, where the method includes step S200 and step S210.

Step S200: when the RTC task is executed, detecting whether a system in the electronic equipment is in a sleep state;

step S210: and when the system is detected not to be in sleep, executing the RTC task to sleep for a first preset time and then running the RTC awakening task.

Prior to step S200, the method may further comprise:

setting to run the RTC task every other second preset time;

and running the RTC awakening task at intervals of a third preset time.

It should be noted that there are 2 CPUs for the Android mobile phone, which are a baseband CPU and an application CPU respectively. A baseband CPU: the system comprises a time crystal oscillator, a timing function and a call. The application CPU is used for controlling the operation of the APP. In general, the application CPU is not used for a long time and enters a sleep state (power consumption of the mobile phone is reduced), and in this state, the application enters a stop state. But the baseband CPU can call the application CPU through the time crystal oscillator, thereby putting the application into a running state.

In this embodiment, the RTC (Real-Time Clock) task indicates that the alarm Clock is not available in the sleep state, and does not wake up the CPU, which saves power consumption. The RTC awakening task indicates that the alarm clock can awaken the system and execute a prompt function in a dormant state, and can awaken the CPU, so that relative power consumption is realized. The RTC task delays the execution of the RTC wake-up task to achieve the condition of waking up by multiplexing other applications or waking up by itself, thereby sending and receiving messages. Thereby reaching the power saving function of the application.

Referring to fig. 3, after step S200, the method further includes:

step S220: and when the system is detected to be dormant, canceling the RTC awakening task running at intervals of a third preset time and starting the RTC awakening task after a fourth preset time.

In this embodiment, the third preset time may be 10 minutes, and the fourth preset time may be 10 minutes. The first preset time may be 10 minutes, and the second preset time may be 1 minute.

The embodiment of the invention provides a power saving method, which is applied to electronic equipment and comprises the following steps: when the RTC task is executed, detecting whether a system in the electronic equipment is in a sleep state; and when the system is detected not to be in sleep, executing the RTC task to sleep for a first preset time and then running the RTC awakening task. The RTC task is delayed to run in a mode of delaying the RTC awakening task by preset time of RTC task dormancy, so that power saving is realized.
