[0041] Next, the technical solutions in the present application will be described with reference to the accompanying drawings.

[0042] In order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish identical or similar items with basically the same functions and effects. For example, the first instruction and the second instruction are used to distinguish different user instructions, and the sequence order thereof is not limited. Those skilled in the art can understand that terms such as "first" and "second" do not limit the quantity and execution order, and terms such as "first" and "second" do not necessarily mean different.

[0043] It should be noted that in the present application, words such as "exemplarily" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplarily" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, using words such as "exemplarily" or "for example" aims to present relevant concepts in a specific manner.

[0044] In addition, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B may be singular or plural. The character " / " generally represents that the associated objects before and after are in an "or" relationship. "At least one (item)" or its similar expression below refers to any combination of these items, including any combination of single item (item) or plural items (items). For example, at least one (item) of a, b, and c may represent: a, or b, or c, or a and b, or a and c, or b and c, or a, b, and c, where a, b, and c may be single or multiple.

[0045] Figure 1A schematic block diagram of application scenario 100 provided by an embodiment of the present application. As Figure 1 shown, application scenario 100 includes a first electronic device 101 and a second electronic device 102. The first electronic device 101 may include a battery (not shown in the figure). When the second electronic device 102 is connected to the first electronic device, it can charge the battery of the first electronic device.

[0046] It should be understood that in the above charging scenario, the greater the system power consumption, the higher the device temperature of the current first electronic device 101 can be indicated. Therefore, the first electronic device 101 can determine whether there is a problem of poor user experience caused by too high device temperature based on the system power consumption, and then take relevant measures to balance the charging rate and the temperature of the first electronic device 101 when it is determined that the device temperature is too high. However, it is difficult to obtain the current output current of the above second electronic device 102, resulting in difficulties and inaccuracies in calculating the system power consumption.

[0047] In view of this, an embodiment of the present application provides a method for calculating system power consumption and an electronic device. The first electronic device can obtain the current output current of the second electronic device at least based on the current reduction data of the second electronic device. Since the above current reduction data is used to indicate the maximum value of the output current of the second electronic device at a preset moment, that is, without any physical channel, the first electronic device can accurately calculate the current output current of the second electronic device at the preset moment as the current corresponding to the preset moment, and then can realize efficient and accurate calculation of the system power consumption based on the current output current.

[0048] It should be understood that the second electronic device involved in the embodiments of the present application may be an adapter, and the first electronic device may be a mobile phone, a tablet computer, a laptop computer, a handheld computer, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a smart screen, an artificial intelligence (AI) speaker, headphones, a terminal in industrial control, a terminal in self-driving, a terminal in remote medical surgery, a terminal in a smart grid, a terminal in transportation safety, a terminal in a smart city, a terminal in a smart home, a personal digital assistant (PDA), etc. The embodiments of the present application are not limited thereto.

[0050] As Figure 2 shown, the first electronic device includes a processor 210, a transceiver 220, and a power supply 230.

[0051] Optionally, the first electronic device may further include a memory 240. The processor 210, the transceiver 220, and the memory 240 may communicate with each other through an internal connection path to transfer charging data. The memory 240 is used to store a computer program, and the processor 210 is used to call and run the computer program from the memory 240.

Specifically, the memory 240 may also be integrated in the processor 210, or independent of the processor 210.

[0054] In addition, in order to make the functions of the first electronic device more complete, the first electronic device may further include one or more of an input unit 250, a sensor 260, etc.

[0057] A memory may also be provided in the processor 210 for storing instructions and data. In some embodiments, the memory in the processor 210 is a cache memory. This memory can save the instructions or data that the processor 210 has just used or recycled. If the processor 210 needs to use the instruction or data again, it can be directly called from the above memory. This avoids repeated accesses, reduces the waiting time of the processor 210, and thus improves the efficiency of the system.

[0058] In some embodiments, the processor 210 may include one or more interfaces. The interfaces may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a general-purpose input / output (GPIO) interface, a subscriber identity module (SIM) interface, and / or a universal serial bus (USB) interface, etc.

[0059] The UART interface is a general-purpose serial data bus for asynchronous communication. This bus can be a bidirectional communication bus. It converts the data to be transmitted between serial communication and parallel communication. In some embodiments, the UART interface is typically used to connect the processor 210 and the transceiver 220. For example, the processor 210 communicates with the Bluetooth module in the transceiver 220 through the UART interface to implement the Bluetooth function. In some embodiments, the audio circuit 270 can transmit audio signals to the transceiver 220 through the UART interface.

[0060] The GPIO interface can be configured by software. The GPIO interface can be configured as a control signal or a data signal. In some embodiments, the GPIO interface can be used to connect the processor 210 with the transceiver 220, the audio module circuit 280, the sensor 260, etc. The GPIO interface can also be configured as an I2C interface, an I2S interface, a UART interface, etc.

[0061] It can be understood that the interface connection relationships among the modules illustrated in the embodiments of this application are only illustrative descriptions and do not constitute a structural limitation on the first electronic device.

[0062] It can be understood that Figure 2 The power supply 230 shown is used to supply power to the processor 210, the memory 240, the input unit 250, the transceiver 220, etc.

[0063] The transceiver 220 can provide wireless communication solutions applied to the first electronic device, including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared technology (IR), etc. The transceiver 120 can be one or more devices integrating at least one communication processing module.

[0064] The memory 240 can be used to store computer-executable program code, and the above executable program code includes instructions. The memory 240 can include a program storage area and a data storage area. Among them, the program storage area can store an operating system, application programs required for at least one function, etc. The data storage area can store data created during the use of the first electronic device (such as charging data), etc. In addition, the memory 240 can include high-speed random access memory, and can also include non-volatile memory, such as at least one disk storage device, a flash memory device, a universal flash storage (UFS), etc. The processor 210 executes various functional applications and data processing of the first electronic device by running the instructions stored in the memory 240, and / or the instructions stored in the memory provided in the processor.

[0065] The first electronic device can implement audio functions through the audio circuit 270, as well as an application processor, etc. For example, playing a charging completion prompt tone, playing a start charging prompt tone, etc.

[0066] The audio circuit 270 is used to convert digital audio information into an analog audio signal for output, and is also used to convert an analog audio input into a digital audio signal. The audio circuit 270 can also be used for encoding and decoding audio signals. In some embodiments, the audio circuit 270 can be disposed in the processor 210, or a partial functional module of the audio circuit 270 can be disposed in the processor 210.

[0067] In order to make the objectives and technical solutions of the present application clearer and more intuitive, the following will, in conjunction with the accompanying drawings and embodiments, elaborate in detail on the system power consumption calculation method and the electronic device provided by the embodiments of the present application. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0068] Figure 3 is a schematic flowchart of a system power consumption calculation method 300 provided by an embodiment of the present application. The method 300 can be applied to Figure 1 the application scenario shown, and in addition, it can also be applied to other application scenarios, which are not limited in the present application. The present application can be executed by a first electronic device including a battery, and the battery can be charged by a second electronic device. As Figure 3 shown, the method 300 can include the following steps:

[0069] S301, when the battery is in a charging state, the first electronic device obtains the current current of the battery, the current voltage of the battery, the current output current of the second electronic device, and the current output voltage of the second electronic device.

[0070] In a possible implementation, the first electronic device determines the current output current of the second electronic device based on the current reduction data.

[0071] It should be understood that the current reduction data may include the correspondence between at least one preset moment and at least one current (which can be understood as the output current), and this current reduction data is used to indicate that in the case of the above at least one preset moment, the output current of the second electronic device is equal to the output current corresponding to the above at least one preset moment.

[0072] Exemplarily, at least one preset moment in the above current reduction data includes a first preset moment. The first electronic device can determine a first output current from the above current reduction data, and this first output current is the output current corresponding to the first preset moment in the above current reduction data. The first electronic device can determine that the current output current of the second electronic device is equal to the above first output current.

[0073] It should be understood that the above first preset moment can be the acquisition moment of acquiring the above current output current or can be the moment in the current reduction data that is separated from the above acquisition moment by a preset time interval.

[0074] In a possible implementation, the first electronic device may pre-store the correspondence between the current reduction data of multiple electronic devices and the identities (identification, ID) of these multiple electronic devices. The IDs of these multiple electronic devices include the ID of the second electronic device. The first electronic device can, when receiving the ID of the second electronic device sent by the second electronic device, obtain the current reduction data of the second electronic device based on this ID of the second electronic device.

[0075] It should be understood that at least one output current corresponding to at least one preset moment in the above current reduction data can be the maximum value, that is, the current reduction data can be used to indicate the maximum value of the output current of the second electronic device at the preset moment.

[0076] S302, the first electronic device determines the system power consumption of the first electronic device based on the current current, the current voltage, the current output current, and the current output voltage.

[0077] In this application, the first electronic device can obtain the current output current of the second electronic device at least based on the current reduction data of the second electronic device. Since the above current reduction data is used to indicate the maximum value of the output current of the second electronic device at the preset moment, that is, without any physical channel, the first electronic device can accurately calculate at the preset moment that the current output current of the second electronic device is the current corresponding to the above predetermined moment, and based on this current output current, an efficient and accurate calculation of the system power consumption is achieved.

[0078] In addition, when determining the power consumption of the above system, the first electronic device can also judge the temperature of the current first electronic device based on the system power consumption. For example, when it is determined that the temperature of the first electronic device is too high, the first electronic device can take corresponding current reduction measures to balance the charging rate and the temperature of the first electronic device, and avoid the problem of poor user experience caused by too low charging rate and / or too high temperature of the first electronic device.

[0079] Taking the first electronic device as a mobile phone and the second electronic device as an adapter as an example, the method for calculating the system power consumption provided in this application will be described below.

[0080] Figure 4 It is a schematic flowchart of a method 400 for calculating the system power consumption provided in an embodiment of this application. As Figure 4 shown, the method 400 includes the following steps:

[0081] S401, the adapter sends the adapter ID to the mobile phone. Correspondingly, the mobile phone receives the adapter ID from the adapter.

[0082] S402, the mobile phone determines the current reduction data of the adapter based on the above adapter ID.

[0083] It should be understood that the current reduction data may include at least one correspondence between a preset moment and at least one output current.

[0084] Table 1 shows the current reduction data of the adapter provided in this application.

[0085] Table 1

[0086] Preset moment Output current First preset moment First output current Second preset moment Second output current Third preset moment Third output current

[0087] As shown in Table 1, the above current reduction data includes the correspondence between three preset moments and three output currents. As described in Table 1, the output current corresponding to the first preset moment is the first output current, the output current corresponding to the second preset moment is the second output current, and the output current corresponding to the third preset moment is the third output current. Among them, the second preset moment is earlier than the first preset moment, the third preset moment is earlier than the second preset moment, the first output current is less than the second output current, and the second output current is less than the third output current.

[0088] It should be understood that the current reduction data shown above is only exemplary. In addition to the preset moments and output currents shown above, the current reduction data may also include the correspondence between a preset time period and an output current, the relationship between a preset moment and the adjustment amount of the output current, or the relationship between a preset time period and the adjustment amount of the output current. This application does not make any limitations in this regard.

[0089] S403, the mobile phone sends the first message to the adapter. Correspondingly, the adapter receives the first message from the mobile phone, and the first message is used to instruct the adapter to start charging the battery of the mobile phone.

[0090] S404, the mobile phone activates the first timer.

[0091] S405, the adapter activates the second timer.

[0092] It should be understood that the closer the activation times of the above-mentioned first timer and second timer are, the more accurate the output current of the adapter determined subsequently will be. In the case where the activation time of the above-mentioned first timer is later than that of the second timer, the mobile phone can, when using the timing moment of the first timer subsequently, add the time difference between the activation time of the first timer and the activation time of the second timer to the actually obtained timing moment, thereby realizing the timing synchronization between the mobile phone and the adapter and improving the accuracy of the current output current of the adapter. In the embodiments of the present application, the calculation method of the system power consumption provided by the present application is mainly described by taking the activation times of the above-mentioned first timer and second timer as the same as an example.

[0093] S406, the adapter charges the battery of the mobile phone with the initial output current. Correspondingly, the mobile phone accepts the second device to charge its battery.

[0094] In a possible implementation manner, the above-mentioned initial current can be determined according to the battery power.

[0095] Exemplarily, when the adapter is connected to the mobile phone and the mobile phone determines that the current battery power is x%, the mobile phone determines that the maximum charging current of the current battery is y and sends the maximum charging current to the adapter. Correspondingly, the adapter receives the maximum charging current and uses the maximum charging current as the above-mentioned initial output current to charge the mobile phone battery.

[0096] It should be understood that the above-mentioned current reduction data is used to instruct that in the case of the above-mentioned at least one preset moment, the adapter adjusts the output current to the output current corresponding to the above-mentioned at least one moment.

[0097] Exemplarily, when the timing moment of the second timer is equal to the first preset moment shown in Table 1 above, the adapter can adjust its current output current to the output current corresponding to the first preset moment, that is, the first output current. When the timing moment of the second timer is equal to the second preset moment shown in Table 1 above, the adapter can adjust its current output current to the output current corresponding to the second preset moment, that is, the second output current. Or, when the timing moment of the second timer is equal to the third preset moment shown in Table 1 above, the adapter can adjust its current output current to the output current corresponding to the third preset moment, that is, the third output current.

[0098] S407. The mobile phone determines the current output current of the adapter based on the timing moment of the first timer and the current-down data of the adapter.

[0099] In a possible case, when it is determined that the timing moment of the first timer is the same as the first preset moment in the current-down data, the mobile phone can determine that the adapter is currently performing, or about to perform, a current-down operation, that is, adjusting the current output current to the output current corresponding to the first preset moment. In other words, when the moment when the mobile phone obtains the current output current of the adapter is equal to the first preset moment, the mobile phone can determine the first output current corresponding to the first preset moment based on the current-down data, and can determine that the current output current of the adapter is equal to the output current corresponding to the first preset moment, that is, the first current.

[0100] In another possible case, when it is determined that the timing moment of the first timer is different from the first preset moment in the current-down data, the mobile phone can determine the output current of the adapter based on the timing moment of the first timer, the first preset moment, and the moment separated by a preset time interval from the timing moment of the first timer (that is, the moment when the current output current of the adapter is obtained).

[0101] Exemplarily, when the timing moment of the first timer is between the first preset moment and the second preset moment, the mobile phone can determine that the current output current of the adapter is the output current corresponding to the second preset moment. The mobile phone can determine the second output current corresponding to the second preset moment based on the second preset moment and the current-down data shown in Table 1, and determine that the current output current of the adapter is equal to the second output current.

[0102] Exemplarily, when the timing moment of the first timer is not between the first preset moment and the second preset moment, and the timing moment of the first timer is greater than the first preset moment, the mobile phone can determine that the most recent current reduction operation of the adapter was performed at the first preset moment. The mobile phone can determine the first output current corresponding to the first preset moment based on the first preset moment and the current reduction data shown in Table 1 above, and determine that the current output current of the adapter is equal to the first output current.

[0103] S408, the mobile phone determines the system power consumption based on the current current of the battery, the current voltage of the battery, the current output current of the adapter, and the current output voltage of the adapter.

[0104] Exemplarily, the system power consumption satisfies the following formula: Psys = v bus *i bus *loss - v batt *i batt , where Psys is the above-mentioned system power consumption, v bus is the current output voltage of the adapter, i bus is the current output current of the adapter, v batt is the current voltage of the battery, i batt is the current current of the battery, and loss is the path loss and the device conversion rate loss.

[0105] It should be understood that when the adapter charges the mobile phone, the mobile phone and the adapter time simultaneously. Therefore, the mobile phone can determine whether there is a current reduction of the second device at the current moment based on the timing moment and the current reduction data of the second device. Furthermore, when it is determined that there is a current reduction, without any physical channel, the mobile phone can accurately determine that the current output current of the adapter is the current corresponding to the above-mentioned timing moment. In other words, since the efficiency and accuracy of the determined current output current of the adapter are relatively high, the efficiency and accuracy of the calculated system power consumption are also relatively high.

[0106] Optionally, the mobile phone can also judge the current temperature of the current mobile phone based on the system power consumption, and then can take corresponding current reduction measures to balance the charging rate and the temperature of the mobile phone, and avoid the problem of poor user experience caused by too low charging rate and / or too high mobile phone temperature.

[0107] Optionally, in addition to the first device determining the current output current of the second device based on the current reduction data as shown above, the first electronic device also determines the current output current of the second electronic device based on the above-mentioned current reduction data and reference information. Wherein, the reference information includes the current voltage of the battery or the reference output current.

[0108] The following takes the above reference information where the current voltage of the battery is, the first electronic device is a mobile phone, and the second electronic device is an adapter as an example to describe in detail the method for calculating the system power consumption provided by this application.

[0109] Figure 5 It is a schematic flowchart of another method 500 for calculating the system power consumption provided by this application. As Figure 5 shown, the method 500 includes the following steps:

[0110] S501, the adapter sends the adapter ID to the mobile phone. Correspondingly, the mobile phone receives the adapter ID from the adapter.

[0111] S502, the mobile phone determines the current-down data of the adapter based on the above adapter ID.

[0112] It should be understood that the above current-down data includes at least one preset moment and the corresponding at least one output current. The current-down data is used to indicate that in the case of the above at least one moment, the output current of the adapter is equal to the output current corresponding to the above at least one preset moment. For specific details, reference can be made to the description of the above embodiments. To avoid repetition, it will not be elaborated here.

[0113] S503, the mobile phone sends the first information to the adapter. Correspondingly, the adapter receives the first information from the mobile phone. The first information is used to indicate that the adapter starts to charge the battery of the mobile phone, and the first information may carry first charging reference data.

[0114] It should be understood that the above first charging reference data may include multiple voltages and the corresponding multiple currents. The multiple voltages can be understood as multiple battery voltages, and the multiple currents can also be understood as multiple charging currents. The first charging reference data can be used to indicate that when the voltage of the battery is greater than or equal to any one of the above multiple voltages, the output current of the adapter is equal to the charging current corresponding to any one of the above multiple voltages.

[0115] Table 2 shows the first charging reference data provided by the embodiments of this application.

[0116] Table 2

[0117] Battery voltage Charging current First voltage First charging current Second voltage Second charging current Third voltage Third charging current

[0118] As shown in Table 2, the above first charging reference data includes three pairs of relationships between voltage and charging current. As shown in Table 2, when the battery voltage is greater than or equal to the first voltage and less than the second voltage, the charging current of the battery is the first charging current, that is, the output current of the adapter is equal to the above first charging current. When the battery voltage is greater than or equal to the second voltage and less than the third voltage, the charging current of the battery is the second charging current, that is, the output current of the adapter is equal to the above second charging current. When the battery voltage is greater than or equal to the third voltage, the charging current of the battery is the third charging current, that is, the output current of the adapter is equal to the above third charging current.

[0119] S504, the mobile phone turns on the first timer.

[0120] S505, the adapter turns on the second timer.

[0121] It should be understood that the closer the start times of the above first timer and the second timer are, the more accurate the output current of the adapter determined subsequently will be. When the start time of the above first timer is later than the start time of the second timer, the mobile phone can, when using the timing moment of the first timer subsequently, add the time difference between the start time of the first timer and the start time of the second timer on the basis of the actually obtained timing moment, so as to achieve the timing synchronization between the mobile phone and the adapter and improve the accuracy of the current output current of the adapter. In the embodiments of the present application, mainly taking the start time of the above first timer being the same as the start time of the second timer as an example, the calculation method of the system power consumption provided by the present application is described.

[0122] S506, the adapter charges the battery of the mobile phone with the initial output current. Correspondingly, the mobile phone accepts the adapter to charge its battery.

[0123] In a possible implementation manner, the above initial current can be determined according to the battery power.

[0124] Exemplarily, when the adapter is connected to the mobile phone and the mobile phone determines that the current power of the battery is x%, the mobile phone determines that the maximum charging current of the current battery is y and sends the maximum charging current to the adapter. Correspondingly, the adapter receives the maximum charging current and uses the maximum charging current as the above initial output current to charge the battery of the mobile phone.

[0125] S507, the adapter sends information requesting the current voltage of the battery to the mobile phone. Correspondingly, the mobile phone receives the information requesting the current voltage of the battery.

[0126] S508, the mobile phone sends the current voltage of the battery to the adapter based on the above information requesting the current voltage of the battery.

[0127] Optionally, before the mobile phone sends the current voltage of the battery to the adapter based on the information of the requested battery current voltage sent by the adapter, the mobile phone can compare the current voltage of the battery with the voltage of the battery sent to the adapter last time. When it is determined that the current voltage of the battery is different from the voltage of the battery sent to the adapter last time, the mobile phone sends the current voltage of the battery to the adapter. Or, when it is determined that the current voltage of the battery is the same as the voltage of the battery sent to the adapter last time, the mobile phone can do nothing. Correspondingly, when the adapter does not receive the current voltage of the battery sent by the mobile phone within a preset time range, it can be determined not to change the current output current, that is, the adapter keeps charging the battery of the mobile phone with the current output current.

[0128] S509. The adapter determines the current output current based on the current voltage of the battery and the first charging reference data.

[0129] Exemplarily, corresponding to the first charging reference data shown in Table 2 above, when the current voltage of the battery is greater than the first voltage and less than the second voltage, the adapter determines to adjust the initial output current to the first charging current corresponding to the first voltage in Table 2, that is, the current output current of the adapter is equal to the first charging current.

[0130] S510. The adapter charges the battery with the output current. Correspondingly, the mobile phone receives the charging of the battery by the adapter.

[0131] S511. The mobile phone determines the current output current of the adapter based on the current voltage of the battery, the current reduction data, and the timing moment of the first timer.

[0132] In a possible case, when the timing moment of the first timer is the same as the first preset moment in the current reduction data, the mobile phone can determine that the adapter is currently performing or about to perform a current reduction operation at the current moment, and the mobile phone can determine the first output current corresponding to the first preset moment based on the current reduction data. The mobile phone can determine the first charging current corresponding to the voltage of the battery based on the first charging reference data shown in Table 2 and the current voltage of the battery. When the mobile phone determines that the first output current is less than the first charging current, it can determine that the current output current of the adapter is equal to the first output current. Or, when the first output current is greater than or equal to the first charging current, it is determined that the current output current of the adapter is equal to the first charging current.

[0133] In another possible case, when it is determined that the timing moment of the first timer is different from the first preset moment in the above-mentioned down-current data, the mobile phone can determine the output current of the adapter based on the timing moment of the first timer, the first preset moment, and the moment separated by a preset time interval from the timing moment of the first timer (i.e., the acquisition moment of the current output current of the adapter).

[0134] Exemplarily, the timing moment of the first timer is between the first preset moment and the second preset moment. The mobile phone can determine the second output current corresponding to the second preset moment based on the second preset moment and the down-current data shown in Table 1. The mobile phone can determine the first charging current corresponding to the current voltage of the battery based on the first charging reference data shown in Table 2 and the current voltage of the battery. The mobile phone can determine that the current output current of the adapter is equal to the second output current when it is determined that the second output current is less than the second charging current. Or, when the mobile phone determines that the second output current is greater than or equal to the first charging current, it determines that the current output current of the adapter is equal to the first charging current.

[0135] Exemplarily, the timing moment of the first timer is not between the first preset moment and the second preset moment, and the timing moment of the first timer is greater than the first preset moment. The mobile phone can determine that the most recent down-current operation of the adapter was performed at the first preset moment. The mobile phone can determine the first output current corresponding to the first preset moment based on the first preset moment and the down-current data shown in the above Table 1, and determine that the current output current of the adapter is equal to the first output current when it is determined that the first output current is less than the first charging current. Otherwise, the mobile phone can determine that the current output current of the adapter is equal to the first charging current.

[0136] S512, the mobile phone determines the system power consumption based on the current current of the battery, the current voltage of the battery, the current output current of the adapter, and the current output voltage of the adapter.

[0137] Exemplarily, the above system power consumption satisfies the following formula: Psys = v bus *i bus *loss - v batt *i batt , where Psys is the above system power consumption, v bus is the current output voltage of the adapter, i bus is the current output current of the adapter, v batt is the current voltage of the battery, i batt is the current current of the battery, and loss is the path loss and the device conversion rate loss.

[0138] It should be understood that when the adapter charges the mobile phone, without any physical channels, the mobile phone can accurately determine the current output of the adapter at the corresponding time of the timing moment, the current reduction data of the second device, the first charging reference data, and the current voltage of the battery, that is, the current corresponding to the timing moment or the current corresponding to the current voltage of the battery. In other words, due to the high efficiency and accuracy of the determined current output of the adapter, the efficiency and accuracy of the calculated system power consumption are also relatively high.

[0139] Similarly, the mobile phone can also take corresponding current reduction measures based on the system power consumption, taking into account the charging rate and the temperature of the mobile phone, and avoiding the problem of poor user experience caused by too low charging rate and / or too high temperature of the mobile phone.

[0140] Taking the above reference information as the reference output current, the first electronic device as the mobile phone, and the second electronic device as the adapter as an example, the calculation method of the system power consumption provided by the present application will be described in detail below.

[0141] Figure 6 It is a schematic flowchart of another calculation method 600 of the system power consumption provided by the present application. As Figure 6 shown, the method 600 includes the following steps:

[0142] S601, the adapter sends the adapter ID to the mobile phone. Correspondingly, the mobile phone receives the adapter ID from the adapter.

[0143] S602, the mobile phone determines the current reduction data of the adapter based on the above adapter ID.

[0144] It should be understood that the above current reduction data includes at least one preset moment and the corresponding at least one output current, and the current reduction data is used to indicate that in the case of the above at least one preset moment, the output current of the adapter is equal to the at least one output current corresponding to the preset moment. For specific details, reference can be made to the description of the above embodiments. To avoid repetition, it will not be elaborated here.

[0145] S603, the mobile phone sends the first information to the adapter. Correspondingly, the adapter receives the first information from the mobile phone, and the first information is used to indicate that the adapter starts to charge the battery of the mobile phone.

[0146] Optionally, the above first information can also carry the first charging reference data or the second charging reference data. The second charging parameter includes at least one voltage (which can be understood as the battery voltage) and at least one corresponding current (which can be understood as the charging current). Among them, at least one battery voltage in the second charging reference data is greater than the maximum voltage that the battery can reach in the embodiments of the present application. In addition, the first charging reference data can be referred to the description of the above embodiments and Table 2. To avoid repetition, it will not be elaborated here.

[0147] S604, the mobile phone activates the first timer.

[0148] S605, the adapter activates the second timer.

[0149] It should be understood that the closer the activation times of the above-mentioned first timer and second timer are, the more accurate the output current of the subsequent determined adapter will be. To avoid repetition, no further elaboration will be made here. For specific details, reference can be made to the description of the above embodiments.

[0150] S606, the adapter charges the battery of the mobile phone with the initial output current. Correspondingly, the mobile phone accepts the adapter to charge its battery.

[0151] In a possible implementation manner, the above initial current can be determined based on the battery power.

[0152] Exemplarily, when the adapter is connected to the mobile phone and the mobile phone determines that the current battery power is x%, the mobile phone determines that the maximum charging current of the current battery is y, and sends the maximum charging current to the adapter. Correspondingly, the adapter receives the maximum charging current and uses the maximum charging current as the above initial output current to charge the mobile phone battery.

[0153] S607, the adapter sends information requesting the current current of the battery to the mobile phone. Correspondingly, the mobile phone receives the information requesting the current current of the battery.

[0154] In a possible implementation manner, the adapter sends information requesting the current voltage of the battery to the mobile phone. When the mobile phone receives the information requesting the current voltage of the battery, it sends an indication message to the adapter. The adapter can receive the indication message and send the above information requesting the current current of the battery to the mobile phone based on the indication message.

[0155] S608, the mobile phone sends a reference output current to the adapter based on the above information requesting the current current of the battery.

[0156] Optionally, the above reference output current can also be less than or equal to a limit current, which is used to indicate the maximum current corresponding to the mobile phone when running at least one application.

[0157] Exemplarily, the adapter charges the battery when the mobile phone is running a game application. The mobile phone can determine the charging current corresponding to the current voltage of the battery based on the current voltage of the current battery and the first charging reference data shown in Table 2 based on the information of the current current of the requested battery. When the mobile phone determines that the charging current corresponding to the current voltage of the battery is less than or equal to the above-mentioned limit current, it can determine that the above-mentioned reference output current is equal to the charging current corresponding to the current voltage of the battery. Or, when it is determined that the charging current corresponding to the current voltage of the battery is greater than the above-mentioned limit current, in order to balance the charging speed and user experience, the mobile phone can determine that the reference output current is equal to the limit current, that is, the adapter charges the battery with a reference output current less than or equal to the limit current, avoiding the problem of poor user experience caused by the overheating of the mobile phone during the charging process when running the game application.

[0158] Optionally, before the mobile phone sends the current current of the battery to the adapter based on the information of the current current of the requested battery sent by the adapter, the mobile phone can compare the current current of the battery with the current of the battery sent to the adapter last time. When it is determined that the current current of the battery is different from the current of the battery sent to the adapter last time, the mobile phone sends the current current of the battery to the adapter. Or, when it is determined that the current current of the battery is the same as the current of the battery sent to the adapter last time, the mobile phone can do nothing. Correspondingly, when the adapter does not receive the current current of the battery sent by the mobile phone within a preset time range, it can determine not to change the current output current, that is, the adapter continues to charge the battery of the mobile phone with the above-mentioned current output current.

[0159] S609, the adapter charges the battery of the mobile phone with the above-mentioned reference output current. Correspondingly, the mobile phone receives the charging of the battery by the adapter.

[0160] S610, the mobile phone determines the current output current of the adapter based on the above-mentioned reference output current, the current reduction data, and the timing moment of the above-mentioned first timer.

[0161] In a possible case, when the timing moment of the above-mentioned first timer is the same as the first preset moment in the above-mentioned current reduction data, the mobile phone can determine that the adapter is currently performing, or will perform, a current reduction operation at the current moment. The mobile phone can determine the first output current corresponding to the first preset moment based on the above-mentioned current reduction data. When the mobile phone determines that the first output current is less than the reference output current, it can determine that the current output current of the adapter is equal to the first output current. Or, when the first output current is greater than or equal to the reference output current, it is determined that the current output current of the adapter is equal to the reference output current.

[0162] In another possible case, when it is determined that the timing moment of the first timer is different from the first preset moment in the above-mentioned down-current data, the mobile phone can determine the output current of the adapter based on the timing moment of the first timer, the first preset moment, and the moment separated by a preset time interval from the timing moment of the first timer (i.e., the acquisition moment of the current output current of the adapter).

[0163] Exemplarily, the timing moment of the first timer is between the first preset moment and the second preset moment. The mobile phone can determine the second output current corresponding to the second preset moment based on the second preset moment and the down-current data shown in Table 1. When the mobile phone determines that the second output current is less than the reference output current, it can determine that the current output current of the adapter is equal to the second output current. Alternatively, when the mobile phone determines that the second output current is greater than or equal to the reference output current, it can determine that the current output current of the adapter is equal to the reference output current.

[0164] Exemplarily, the timing moment of the first timer is not between the first preset moment and the second preset moment, and the timing moment of the first timer is greater than the first preset moment. The mobile phone can determine that the most recent down-current operation of the adapter was performed at the first preset moment. The mobile phone can determine the first output current corresponding to the first preset moment based on the first preset moment and the down-current data shown in Table 1 above, and when it determines that the first output current is less than the reference output current, it can determine that the current output current of the adapter is equal to the first output current. Otherwise, the mobile phone can determine that the current output current of the adapter is equal to the reference output current.

[0165] S611, the mobile phone determines the system power consumption based on the current current of the battery, the current voltage of the battery, the current output current of the adapter, and the current output voltage of the adapter.

[0166] Exemplarily, the above-mentioned system power consumption satisfies the following formula: Psys = v bus *i bus *loss - v batt *i batt , where Psys is the above-mentioned system power consumption, v bus is the current output voltage of the adapter, i bus is the current output current of the adapter, v batt is the current voltage of the battery, i batt is the current current of the battery, and loss is the path loss and the device conversion rate loss.

[0167] It should be understood that when the adapter charges the mobile phone, without any physical channels, the mobile phone can accurately determine the current output current of the adapter at the timing moment as the current corresponding to the timing moment or the reference output current based on the timing moment, the down - current data of the second device, and the reference output current. In other words, since the efficiency and accuracy of the determined current output current of the adapter are relatively high, the efficiency and accuracy of the calculated system power consumption are also relatively high.

[0168] Similarly, the mobile phone can also take corresponding down - current measures based on the system power consumption, taking into account the charging rate and the temperature of the mobile phone, and avoiding the problem of poor user experience caused by too low charging rate and / or too high mobile phone temperature.

[0169] It should be understood that the above - mentioned various embodiments can also be coupled to each other, and this application does not make any limitations in this regard. And the magnitude of the sequence numbers of the above - mentioned processes does not mean the sequence of execution. The execution sequence of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of this application.
