Description

Technical Field

[0001] This application relates to the field of charging and discharging technology, and in particular to a wireless charging method, electronic device, and readable storage medium. Background Technology

[0002] For two electronic devices that support wireless charging, one device can be used to charge the other. For example, Figure 1 The diagram illustrates a charging scenario where both the smartwatch 10 and the phone 20 have built-in wireless charging coils and support wireless charging technology. When the smartwatch 10 is placed on the back cover of the phone 20, the phone 20's wireless charging coil (acting as a transmitting coil) generates a constantly changing magnetic field. The smartwatch 10's wireless charging coil (acting as a receiving coil) senses this change in the magnetic field and generates an induced current, which is then converted into direct current to charge the smartwatch 10. Furthermore, the charging efficiency is optimal when the geometric center of the smartwatch 10's receiving coil matches the geometric center of the phone 20's transmitting coil.

[0003] However, in some scenarios, neither the smartwatch 10 nor the phone 20 supports magnetic charging. When the smartwatch 10 is placed on the back cover of the phone 20, there may be a mismatch between the geometric center of the transmitting coil of the phone 20 and the geometric center of the receiving coil of the smartwatch 10. This results in slow charging speed and severe overheating of the device when the phone 20 reverse charges the smartwatch 10, affecting the user's charging experience. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a wireless charging method, an electronic device, and a readable storage medium.

[0005] In a first aspect, this application provides a wireless charging method applied to a first electronic device. The method includes: during the charging process of the first electronic device, displaying a first prompt message to prompt a user to move the first electronic device in a first direction; moving the first electronic device from a first position to a second position in the first direction; displaying a second prompt message corresponding to a lower charging performance of the first electronic device at the second position compared to its charging performance at the first position, the second prompt message prompting the user to move the first electronic device in a second direction, wherein the second direction is different from the first direction; and displaying a third prompt message corresponding to a higher charging performance of the first electronic device at the second position compared to its charging performance at the first position, the third prompt message prompting the user to continue moving the first electronic device in the first direction.

[0006] It is understood that the first electronic device may refer to the charging device mentioned in the embodiments of this application (such as smartwatch 10).

[0007] In some embodiments of this application, the charging performance of the first electronic device can be referenced to its charging current or charging voltage. If the charging current or charging voltage increases as the first electronic device moves, it indicates that the charging performance of the first electronic device has improved; if the charging current or charging voltage decreases as the first electronic device moves, it indicates that the charging performance of the first electronic device has decreased. When the charging current or charging voltage of the first electronic device at the second position is lower than that at the first position, a second prompt message can be displayed on the display interface of the first electronic device to prompt the user to move the first electronic device in a second direction opposite to the first direction, thereby improving the charging performance of the first electronic device.

[0008] The method provided in this application allows for charging of another device that also lacks magnetic attraction, based on a charging device that does not support magnetic attraction or has a weak magnetic attraction effect. The method can display a prompt on the main interface of the device being charged, instructing the user to move the device to the optimal charging position between itself and the charging device, based on changes in the charging voltage or charging current of the device being charged. This allows the user to move the device to the optimal charging position. Furthermore, by aligning the geometric center of the receiving coil of the device being charged with the geometric center of the transmitting coil of the charging device, the charging performance of the device being charged can be improved, thus increasing its charging efficiency.

[0009] Furthermore, the method provided in this application embodiment enables the geometric center of the receiving coil of the charging device to match the geometric center of the transmitting coil of the charging device, which can improve the charging speed of the first electronic device, alleviate the heat generation problem of the first electronic device, and improve the wireless charging experience of the user when using the first electronic device.

[0010] In one possible implementation of the first aspect above, displaying a first prompt message during the charging process of the first electronic device includes: acquiring first charging data of the first electronic device; and displaying the first prompt message when the first charging data does not meet a first threshold.

[0011] It is understood that the first charging data may refer to the charging current of the smartwatch 10 mentioned in the embodiments of this application, and the first threshold may refer to the target charging current mentioned in the embodiments of this application. In some other embodiments of this application, the first charging data may also refer to the charging voltage of the smartwatch 10, which is not limited here.

[0012] In some embodiments of this application, a first prompt message is displayed based on the first charging data not meeting a first threshold, which can facilitate instructing the user to move the first charging device. The user can move the first electronic device based on the first prompt message, and by moving the first electronic device, the charging voltage or charging current of the first electronic device can be adjusted, so that the charging performance of the first electronic device can be gradually improved.

[0013] In one possible implementation of the first aspect above, when the charging performance of the first electronic device at the second position is lower than that at the first position, displaying a second prompt message includes: acquiring second charging data of the first electronic device at the first position and third charging data of the first electronic device at the second position; and displaying a second prompt message when the second charging data is greater than the third charging data.

[0014] It is understandable that the second charging data may refer to the charging voltage or charging current of the first electronic device at the first position, and the third charging data may refer to the charging voltage or charging current of the first electronic device at the second position.

[0015] In some embodiments of this application, a second prompt message is displayed based on the fact that the second charging data of the first electronic device at the first position is greater than the third charging data of the first electronic device at the second position. This can facilitate instructing the user to move the first charging device. The user can move the first electronic device based on the second prompt message, and by moving the first electronic device, the charging voltage or charging current of the first electronic device can be adjusted from decreasing to increasing, thereby gradually improving the charging performance of the first electronic device.

[0016] In one possible implementation of the first aspect above, when the charging performance of the first electronic device at the second position is higher than that at the first position, a third prompt message is displayed, including: acquiring second charging data of the first electronic device at the first position and third charging data of the first electronic device at the second position; and displaying a third prompt message when the third charging data is greater than the second charging data.

[0017] In some embodiments of this application, a third prompt message is displayed based on the fact that the third charging data of the first electronic device at the second position is greater than the second charging data of the first electronic device at the first position. This can facilitate instructing the user to move the first charging device. The user can move the first electronic device based on the third prompt message, and by moving the first electronic device, the charging voltage or charging current of the first electronic device can be adjusted to continue to increase, thereby gradually improving the charging performance of the first electronic device.

[0018] In one possible implementation of the first aspect above, the method further includes: the first electronic device moving from the second position to the third position in a first direction; corresponding to the charging performance of the first electronic device at the third position being higher than that at the second position, displaying a fourth prompt message, the fourth prompt message being used to prompt the user to stop moving the first electronic device.

[0019] In one possible implementation of the first aspect above, the first electronic device moves from the second position to the third position in a first direction and displays a fourth prompt message, including: acquiring fourth charging data of the first electronic device at the third position; the first electronic device moves from the third position to the fourth position in the first direction and acquires fifth charging data of the first electronic device at the fourth position, wherein the fifth charging data is equal to the fourth charging data; and displaying a fourth prompt message corresponding to the fifth charging data being equal to the fourth charging data.

[0020] It is understandable that the fourth charging data may refer to the charging voltage or charging current of the first electronic device at the third position, and the fifth charging data may refer to the charging voltage or charging current of the first electronic device at the fourth position.

[0021] In some embodiments of this application, a fourth prompt message is displayed based on the fact that the fourth charging data of the first electronic device at the third position is equal to the fifth charging data of the first electronic device at the fourth position. This facilitates instructing the user to stop moving the first charging device, and the user can stop moving the first electronic device based on the fourth prompt message. In this way, the geometric center of the receiving coil of the first electronic device matches the geometric center of the transmitting coil of the charging device, which improves the charging performance of the device being charged, i.e., increases the charging efficiency of the device being charged.

[0022] In one possible implementation of the first aspect above, the method further includes: the first electronic device moving from the first position to the second position in a first direction, displaying a fifth prompt message, the fifth prompt message being used to prompt the user to move the first electronic device in a third direction or a fourth direction; wherein the third direction or the fourth direction is different from the first direction and the second direction, and the third direction or the fourth direction is a direction that improves the charging performance of the first electronic device.

[0023] In some embodiments of this application, the first direction and the second direction may be opposite to each other, the third direction and the fourth direction may be opposite to each other, and the first direction and the second direction are different from the third direction and the fourth direction.

[0024] In some embodiments of this application, when the first electronic device moves to the second position in the first direction, the charging performance of the first electronic device can be improved accordingly. Furthermore, detecting that the first electronic device moves to a third or fourth direction from the second position can further improve the charging performance of the first electronic device. This allows the geometric center of the receiving coil of the first electronic device to be matched with the geometric center of the transmitting coil of the charging device, thereby improving the charging performance of the first electronic device, and thus increasing the charging efficiency of the device being charged.

[0025] In one possible implementation of the first aspect described above, the first charging data and the second charging data include the charging voltage or charging current of the first electronic device.

[0026] In one possible implementation of the first aspect above, the first direction and the second direction are opposite directions, and the third direction and the fourth direction are opposite directions.

[0027] Secondly, embodiments of this application provide an electronic device, including a memory for storing instructions and a processor for executing the instructions to implement the wireless charging method provided in the first aspect and various possible implementations of the first aspect.

[0028] Thirdly, embodiments of this application provide a readable storage medium storing instructions that, when executed on an electronic device, cause the electronic device to perform the wireless communication method provided in the first aspect and various possible implementations of the first aspect.

[0029] Fourthly, embodiments of this application also provide a computer program product, including a computer program / instruction that, when executed by a processor, implements the wireless charging method provided in the first aspect and various possible implementations of the first aspect.

[0030] The beneficial effects of the second to fourth aspects mentioned above can be referred to the relevant descriptions in the first aspect and various possible implementations of the first aspect, which will not be repeated here. Attached Figure Description

[0051] The illustrative embodiments of this application include, but are not limited to, a wireless charging method, an electronic device, and a readable storage medium.

[0052] It is understood that the electronic devices in the embodiments of this application may also be referred to as terminals, electronic devices, user equipment (UE), mobile stations (MS), mobile terminals (MT), etc. Electronic devices may include mobile phones, smart TVs, wearable devices, tablets, computers with wireless transceiver capabilities, cameras with wireless charging, vehicle dashcams, video doorbells with wireless charging, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes.

[0053] As mentioned earlier, when using mobile phone 20 to charge smartwatch 10, since smartwatch 10 and mobile phone 20 do not support magnetic attraction or the magnetic attraction effect is weak, when smartwatch 10 is placed on the back cover of mobile phone 20 for charging, there will be a situation where the geometric centers of the transmitting coil of mobile phone 20 and receiving coil of smartwatch 10 are mismatched, resulting in slow charging speed, serious device overheating, and affecting the user's charging experience.

[0054] To address the aforementioned issues, this application provides a wireless charging method. The method includes: acquiring the charging current of the device being charged; when the charging current is not the target current; prompting the user to slowly move the charging position of the device on the device's interface; and acquiring the charging voltage Vrect of the device in real time. If the charging voltage Vrect decreases, the user is prompted to move in the opposite direction to the current moving direction of the device; if the charging voltage Vrect increases, the user is prompted to continue moving in the current direction of the device until the charging voltage Vrect no longer changes with the movement of the device, indicating to the user that the device is currently in the optimal charging position. It is understood that as the charging voltage increases, the charging performance of the device also improves.

[0055] Using the above method, when charging another device that also lacks magnetic attraction or has weak magnetic attraction using a charging device that does not support magnetic attraction, the system can display a prompt on the main interface of the device being charged, based on changes in the charging voltage of the device being charged. This prompt instructs the user to move the device to the optimal charging position between the two devices. This allows the user to move the device to the optimal charging position. In this way, the geometric center of the receiving coil of the device being charged is matched with the geometric center of the transmitting coil of the charging device, improving charging efficiency.

[0056] Furthermore, the method provided in this application embodiment enables the geometric center of the receiving coil of the charging device to match the geometric center of the transmitting coil of the charging device, which can improve the charging speed of the first electronic device, alleviate the heat generation problem of the first electronic device, and improve the wireless charging experience of the user when using the first electronic device.

[0057] It is understood that one of the charging device and the device being charged may support magnetic attraction, while the other may not; or, in scenarios where both the charging device and the device being charged support magnetic attraction but the magnetic attraction effect is not very good, this application is also applicable.

Users can click on "Settings" 2011 to enable the mobile phone 20 to display settings such as... Figure 2B The image shows the "Settings" application interface 202 of the mobile phone 20. Users can click on the operation control 2021 corresponding to "Battery" in interface 202 to make the mobile phone 20 display the following... Figure 2C The "Battery" corresponding function interface 203 is shown. Users can activate the wireless reverse charging function of phone 20 by clicking the operation control 2031, which indicates that the wireless reverse charging function is enabled. This will cause phone 20 to display the following... Figure 2D The wireless reverse charging function interface 204 is shown. Figure 2D The interface 204 shown displays a prompt message 2041 instructing the user to perform wireless reverse charging: "Please place a wireless charging-enabled device (phone, wearable device, etc.) on the back of this device," as described above. Figure 1 As shown, the smartwatch 10 can be placed on the back of the phone 20 for wireless charging.

[0061] It is understood that in some other embodiments, the wireless reverse charging function of the mobile phone 20 may be automatically activated when the mobile phone 20 is powered on, and this is not limited here.

The interface 501 of the smartwatch 10 displays the battery level information "4%" and a prompt message "Please ensure there are no metal foreign objects between the watch and the charging device to avoid affecting normal charging," prompting the user to correctly use the mobile phone 20 to wirelessly charge the smartwatch 10.

[0095] S402: Start inertial measurement unit calibration.

[0096] In some embodiments of this application, when it is determined that the smartwatch 10 is in a wireless charging state, the sensor module of the smartwatch 10 can enable inertial measurement unit (IMU) calibration to obtain the acceleration and orientation of the smartwatch 10 when it moves its wireless charging position.

[0097] An IMU (Integrated Measurement Unit) is a sensor used to measure and track the acceleration, angular velocity, and attitude of an object. An IMU can contain one or more accelerometers, gyroscopes, and magnetometers. The accelerometer measures the acceleration of the smartwatch 10 as it moves along three axes (x, y, z). Acceleration is a vector quantity with magnitude and direction, used to describe the rate and direction of change in an object's velocity. The accurate real-time direction of movement of the smartwatch 10 is obtained by processing the acceleration along the three axes using algorithms. The accelerometer can consist of a microelectromechanical system (MEMS) sensor and a signal processing chip. The MEMS sensor detects the acceleration of the smartwatch 10, and the sensor module can read the acceleration of the smartwatch 10 from the signal processing chip and determine the direction of movement of the smartwatch 10 through communication interfaces such as the inter-integrated circuit (I2C) interface and the serial peripheral interface (SPI).

[0098] Furthermore, the gyroscope can measure the angular velocity of the smartwatch 10 around three axes as it moves. Angular velocity is a vector with magnitude and direction, used to describe how fast an object rotates around a fixed point or axis; its direction is perpendicular to the plane of rotation. The magnetometer can measure the magnetometer data of the smartwatch 10, i.e., the strength and direction of the Earth's magnetic field at the location of the smartwatch 10. Moreover, by fusing the measurement data from the accelerometer, gyroscope, and magnetometer using an algorithm, the real-time attitude of the smartwatch 10 during movement can be obtained.

[0099] In some other embodiments of this application, a fusion algorithm can be used to fuse and calculate parameters such as acceleration, angular velocity, and magnetometer data when the electronic device moves in real time, so as to obtain the accurate real-time movement direction of the electronic device. This is not limited here.

[0100] It is understood that the above algorithms may include Kalman filtering, complementary filtering, and quaternion filtering, etc., and are not limited here.

[0101] S403: Obtain charging current.

[0102] In some embodiments of this application, when the smartwatch 10 is wirelessly charged using the mobile phone 20, the charging current of the smartwatch 10 can be obtained through the charging management module of the smartwatch 10.

[0103] In other embodiments, when the smartwatch 10 is wirelessly charged using the mobile phone 20, the charging voltage of the smartwatch 10 can be obtained through the charging management module of the smartwatch 10, which is not limited here.

[0104] S404: Determine if the charging current is the target charging current.

[0105] In some embodiments of this application, after obtaining the charging current of the smartwatch 10, it can be further determined whether the charging current is the target charging current.

[0106] If the judgment result is yes, return to S403 and obtain the charging current;

[0107] If the judgment result is negative, execute S405 and display a prompt message to the user, prompting them to slowly move the device being charged to align with the charging position.

[0108] It is understandable that the target charging current is designed to optimize the charging efficiency of the smartwatch 10 while protecting its battery, thereby extending the lifespan of the smartwatch 10. For example, the target charging current could be 1A, 2A, etc., and is not limited here.

[0109] It is understandable that in some scenarios, the target charging current will be different when using different charging devices to wirelessly charge the smartwatch 10.

[0110] In other embodiments, after obtaining the charging voltage of the smartwatch 10, it can be further determined whether the charging current is the target charging voltage. The target charging voltage can be a voltage that makes the charging efficiency of the smartwatch 10 optimal while protecting its battery, and does not exceed the maximum preset charging voltage of the battery, which can extend the service life of the smartwatch 10.

[0111] S405: Displays a prompt message to the user, suggesting that they slowly move the device being charged to align it with the charging position.

[0112] In some embodiments of this application, if it is determined by S404 that the charging current is not the target charging current, then the display interface of the smartwatch 10 can be controlled to display a prompt message prompting the user to slowly move the device being charged to align with the charging position.

[0113] For example, Figure 5B A schematic diagram 502 of a charging interface for a smartwatch 10 is shown. The smartwatch 10 is positioned on the back of a mobile phone 20 for charging. The interface 502 of the smartwatch 10 displays the prompt message "Slowly move the device being charged to align with the charging position," prompting the user to slowly move the device to align with the charging position. This ensures that the geometric center of the receiving coil of the smartwatch 10 matches the geometric center of the transmitting coil of the mobile phone 20, thereby improving the charging efficiency of the smartwatch 10.

[0114] Furthermore, users can move the charging port on the back of the smartwatch 10 to be located on the back of the phone 20. For example... Figures 5C to 5F The diagram shows the charging position changes of the smartwatch 10. Figure 5C In the middle, the smartwatch 10 moves upward along the Y direction, which corresponds to the vertical direction of the mobile phone 20. Figure 5D In the middle, the smartwatch 10 moves downward along the Y direction, which corresponds to the vertical direction of the mobile phone 20. Figure 5E In the middle, the smartwatch 10 moves to the left along the X direction, which corresponds to the horizontal direction of the mobile phone 20. Figure 5F In the middle, the smartwatch 10 moves to the right along the X direction, which corresponds to the horizontal direction of the mobile phone 20.

[0115] S406: Read calibration data and charging voltage.

[0116] In some embodiments of this application, the sensor module of the smartwatch 10 can acquire calibration data of the smartwatch 10, which is also IMU data, and the movement direction of the smartwatch 10 can be determined based on the IMU data; and the charging management module of the smartwatch 10 can acquire the charging voltage Vrect of the smartwatch 10. It can be understood that the charging voltage Vrect can reflect the degree of matching between the geometric center of the receiving coil of the smartwatch 10 and the geometric center of the transmitting coil of the mobile phone 20.

[0117] S407: Determine if the charging voltage has increased.

[0118] In some embodiments of this application, after the charging voltage Vrect of the smartwatch 10 is acquired in real time based on S406, it can be further determined whether the acquired charging voltage has increased.

[0119] If the judgment result is yes, proceed to S408 and display a prompt message prompting the user to continue moving the device being charged in this direction;

[0120] If the judgment result is negative, proceed to S409 and display a prompt message prompting the user to move the device being charged in the opposite direction.

[0121] It can be understood that if the charging voltage Vrect increases, it means that the geometric center of the receiving coil of the smartwatch 10 matches the geometric center of the transmitting coil of the mobile phone 20 more closely, and the charging efficiency of the smartwatch 10 is higher. If the charging voltage Vrect decreases, it means that the geometric center of the receiving coil of the smartwatch 10 deviates more from the geometric center of the transmitting coil of the mobile phone 20, and the charging efficiency of the smartwatch 10 is lower.

[0122] As an example, Figure 6 A schematic diagram showing the variation of the charging voltage Vrect is shown.

[0123] like Figure 6 As shown, the horizontal axis is used to indicate the period, and the vertical axis is used to indicate the voltage value. It can be seen that as the smartwatch 10 moves in real time, corresponding to the changing trend of the charging voltage Vrect in the dashed box 601, the increase of the charging voltage Vrect of the smartwatch 10 indicates that the geometric center of the receiving coil of the smartwatch 10 matches the geometric center of the transmitting coil of the mobile phone 20 more closely, and the charging efficiency of the smartwatch 10 is higher. Corresponding to the changing trend of the charging voltage Vrect in the dashed box 602, the decrease of the charging voltage Vrect of the smartwatch 10 indicates that the geometric center of the receiving coil of the smartwatch 10 deviates more from the geometric center of the transmitting coil of the mobile phone 20, and the charging efficiency of the smartwatch 10 is lower.

[0124] S408: Displays a prompt message to the user, encouraging them to continue moving the device being charged in this direction.

[0125] In some embodiments of this application, if it is determined that the charging voltage Vrect of the smartwatch 10 increases, it indicates that the geometric center of the receiving coil of the smartwatch 10 is more closely matched with the geometric center of the transmitting coil of the mobile phone 20. In this case, a prompt message can be displayed on the interface of the smartwatch 10, prompting the user to continue moving the smartwatch 10 in the current direction, based on the display module of the smartwatch 10.

[0126] For example, Figure 7A A schematic diagram of the interface 701 of a smartwatch 10 is shown. The interface 701 of the smartwatch 10 displays a prompt message 7011 "Please move the watch in this direction", and a prompt mark 7012 instructing the user to move the smartwatch 10 upward along the Y direction. This prompts the user to move the smartwatch 10 upward along the Y direction to adjust the charging position of the smartwatch 10 on the back of the mobile phone 20. This means that moving the smartwatch 10 upward along the Y direction can increase its charging voltage Vrect.

[0127] It is understandable that, depending on the direction in which the user moves the smartwatch 10, it can also be instructed to move along, such as... Figure 7B The diagram shown illustrates the movement direction of the smartwatch 10 during wireless charging. It can be followed along... Figure 7B Moving the charging position of the smartwatch 10 in any of the directions shown increases the charging voltage Vrect of the smartwatch 10. This allows the geometric center of the receiving coil of the smartwatch 10 to better match the geometric center of the transmitting coil of the mobile phone 20, thereby increasing the charging efficiency of the smartwatch 10. No specific limitations are imposed here.

[0128] In other embodiments of this application, the user may be instructed multiple times to move the charging position of the smartwatch 10 based on its current position so that the geometric center of the receiving coil of the smartwatch 10 can be more closely matched with the geometric center of the transmitting coil of the mobile phone 20.

[0129] For example, Figures 7C to 7D This diagram illustrates a scenario where a smartwatch 10 is being used for mobile charging. (Reference) Figure 7C The schematic diagram 702 of the smartwatch 10 interface shows a prompt message 7021 "Please move the watch in this direction," and a prompt icon 7022 instructing the user to move the smartwatch 10 upwards along the Y direction to adjust its charging position on the back of the phone 20. Further, refer to... Figure 7DThe schematic diagram 703 of the smartwatch 10 interface shows a prompt message 7031 "Please move the watch in this direction" and a prompt icon 7032 instructing the user to move the smartwatch 10 to the right along the X direction. This prompts the user to adjust the charging position of the smartwatch 10 on the back of the mobile phone 20 by moving the smartwatch 10 to the right along the X direction. Based on the adjustment of the charging position, the geometric center of the receiving coil of the smartwatch 10 can be matched with the geometric center of the transmitting coil of the mobile phone 20, thereby improving the charging efficiency of the smartwatch 10.

[0130] S409: Displays a prompt message to the user, suggesting that they move the device being charged in the opposite direction.

[0131] In some embodiments of this application, if it is determined that the charging voltage Vrect of the smartwatch 10 decreases, it indicates that the geometric center of the receiving coil of the smartwatch 10 is increasingly deviating from the geometric center of the transmitting coil of the mobile phone 20. In this case, a prompt message can be displayed on the smartwatch 10's interface, controlled by the smartwatch 10's display module, prompting the user to move the smartwatch 10 in the opposite direction to the current direction.

[0132] For example, Figure 8 A schematic diagram 801 of the interface of a smartwatch 10 is shown. The interface 801 displays a prompt message 8011 "Please move the watch in this direction," and a prompt label 8012 instructing the user to move the smartwatch 10 downwards along the Y-direction. This prompts the user to move the smartwatch 10 downwards along the Y-direction to adjust its charging position on the back of the phone 20. In other words, it prompts the user to move the smartwatch 10 downwards along the Y-direction, which is the opposite of "upwards along the Y-direction." This illustrates that moving the smartwatch 10 upwards along the Y-direction decreases its charging voltage Vrect, while moving it downwards along the Y-direction increases its charging voltage Vrect.

[0133] In this way, the charging voltage Vrect of the smartwatch 10 can be changed from decreasing to increasing, which means that the geometric center of the receiving coil of the smartwatch 10 can be more matched with the geometric center of the transmitting coil of the mobile phone 20, thus making the charging efficiency of the smartwatch 10 higher.

[0134] S410: Determines whether the charging voltage remains constant.

[0135] In some embodiments of this application, when the charging voltage Vrect of the smartwatch 10 is acquired in real time during its movement and the user is instructed to move in a certain direction to increase the charging voltage Vrect of the smartwatch 10, it can be determined in real time whether there is a certain voltage value of the charging voltage Vrect that remains unchanged.

[0136] If the judgment result is yes, proceed to S411, display a prompt message to the user that the current location is the preferred charging location, and exit the prompt display interface;

[0137] If the judgment result is negative, return to S408 and display a prompt message prompting the user to move the charging device in this direction.

[0138] It is understandable that if the charging voltage Vrect of the smartwatch 10 increases, it indicates a closer match between the geometric center of the receiving coil of the smartwatch 10 and the geometric center of the transmitting coil of the mobile phone 20. Furthermore, if the charging voltage Vrect of the smartwatch 10 increases to a certain constant value, this voltage value can be used to indicate a closer match between the geometric center of the receiving coil of the smartwatch 10 and the geometric center of the transmitting coil of the mobile phone 20, and the charging position corresponding to this voltage value is a preferred charging position where the smartwatch 10 can achieve higher charging efficiency through the mobile phone 20. Based on this, the smartwatch 10 can exit the prompt interface that suggests the user to move the charging position of the smartwatch 10.

[0139] S411: Displays a message indicating that the user's current location is the preferred charging location and exits the display prompt interface.

[0140] In some embodiments of this application, once it is determined that the charging voltage does not change with the movement of the smartwatch 10, that is, the charging voltage Vrect of the smartwatch 10 increases to a certain voltage value and remains constant, this voltage value can indicate that the geometric center of the receiving coil of the smartwatch 10 matches the geometric center of the transmitting coil of the mobile phone 20, and the charging position corresponding to this voltage value is a preferred charging position where the smartwatch 10 can obtain higher charging efficiency through the mobile phone 20. Based on this, the smartwatch 10 can exit the prompt interface that prompts the user to move the charging position of the smartwatch 10.

[0141] Using the above method, when charging another non-magnetic device with a charging device that does not support magnetic attraction, a prompt message can be displayed on the main interface of the device being charged, based on changes in the charging voltage of the device being charged. This prompts the user to move the device to the optimal charging position between the two devices. This allows the user to move the device to the optimal charging position. In this way, the geometric center of the receiving coil of the device being charged matches the geometric center of the transmitting coil of the charging device, improving charging efficiency.

[0142] To better understand the specific implementation process of this application, the following will further elaborate on it in conjunction with the system software structure of electronic devices and the interaction flow between various structures in the electronic device system.

[0143] Figure 9This is a schematic block diagram of the system software architecture of the electronic device according to an embodiment of the present invention.

[0144] The software system of an electronic device can adopt a layered architecture, event-driven architecture, microkernel architecture, microservice architecture, or cloud architecture. This invention embodiment uses a layered architecture of Android. TM Taking the system as an example, the software structure of the electronic device is illustrated.

[0145] A layered architecture divides software into several layers, each with a clear role and function. Layers communicate with each other through software interfaces. In some embodiments, Android... TM The system is divided into four layers, from top to bottom: application layer, application framework layer, and Android. TM The Android runtime and system libraries, as well as the kernel layer.

[0146] like Figure 9 As shown, the application layer can include a series of application packages. These application packages can include applications such as camera, gallery, WeChat, browser, map, navigation, WLAN, Bluetooth, music, video, and SMS.

[0147] The application framework layer provides application programming interfaces (APIs) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

[0148] like Figure 9 As shown, the application framework layer may include a media provider (MP), a storage manager service (SMS), a package manager service (PMS), a notification manager, a view system, etc.

[0149] Media providers, also known as multimedia databases, use SQLite databases to store information about multimedia files such as images, videos, audio, and documents, which are then used by video players, music players, image galleries, and document editors. Android TM When other applications access the storage directory of multimedia files such as images and perform deletion or renaming operations, the media provider can be used to read the data.

[0150] The storage management service is used to manage system memory. When reading or storing data in various storage directories on system memory, you can request the corresponding read permissions from the storage management service.

[0151] Package Management Service (PMS) is primarily responsible for scanning specified directories in the system, identifying files ending in .apk, parsing these files to obtain all application information, and completing the application installation process. PMS mainly parses all information within the APK's AndroidManifest file, including information about application components such as activity, service, broadcast receiver, and media provider. This information is very useful and is provided to other services.

[0152] The notification manager allows applications to display notifications in the status bar. These notifications can be used to deliver informational messages and can disappear automatically after a short pause, requiring no user interaction. For example, the notification manager can be used to notify users of completed downloads or message alerts. The notification manager can also display notifications as icons or scrolling text in the top status bar, such as notifications from background applications, or as dialog boxes on the screen. Examples include displaying text messages in the status bar, emitting sounds, vibrating electronic devices, and flashing indicator lights.

[0153] Content providers store and retrieve data, making that data accessible to applications. This data can include videos, images, audio, made and received phone calls, browsing history and bookmarks, phone books, etc. View systems include visual controls, such as controls for displaying text, controls for displaying images, etc. View systems can be used to build applications. A display interface can consist of one or more views. For example, a display interface including a text message notification icon could include views for displaying text and views for displaying images.

[0154] Android TM Runtime includes core libraries and a virtual machine. Android TM The runtime is responsible for scheduling and management of the Android system.

[0155] The core library consists of two parts: one part is the functionalities that need to be called by the Java language, and the other part is the Android core library.

[0156] The application layer and application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and application framework layer as binary files. The virtual machine is used to perform functions such as object lifecycle management, stack management, thread management, security and exception management, and garbage collection.

[0157] System libraries can include multiple functional modules. For example: surface manager, 3D graphics processing library (e.g., OpenGL ES), 2D graphics engine (e.g., SGL), media libraries, etc.

[0158] The Surface Manager is used to manage the display subsystem and provides the blending of 2D and 3D layers for multiple applications.

[0159] 3D graphics processing libraries are used to implement 3D graphics drawing, image rendering, compositing, and layer processing. 2D graphics engines are drawing engines for 2D graphics.

[0160] The media library supports playback and recording of various common audio and video formats, as well as still image files. It supports multiple audio and video encoding formats, such as MPEG4, H.264, MP3, AAC, AMR, JPG, and PNG.

[0161] The kernel layer is the layer between hardware and software. The kernel layer includes at least display drivers, camera drivers, touch drivers, sensor drivers, and file system drivers. Among these, the sensor drivers can control the sensors in this embodiment to detect data such as acceleration of the electronic device.

[0162] The embodiments disclosed in this application can be implemented in hardware, software, firmware, or a combination of these implementation methods.
