According to the method, after the target charging power is determined, the electronic equipment can actively send a callback notification message to the first application through the charging drive, wherein the callback notification message is used for indicating the first application to acquire the target power charging information. After the first application obtains the target power charging information, the first application may switch to displaying the target charging icon. In this way, the time for the electronic device to switch and display the high-power charging icon is shortened, so that the first application can quickly switch to display the target charging icon when the charger which is powered on charges the battery on the electronic device based on the target charging power.

The electronic device may send a callback notification message to the battery drive via the charging drive so that the first application may quickly switch to displaying the low power charging icon.

With reference to the first aspect, in one possible implementation manner, the method further includes: and under the condition that the target charging power is smaller than the first power and the low-power charging icon is the same as the initial charging icon, the electronic device does not send callback notification message to the battery driver through the charging driver.

In this way, the finally determined target charging power is smaller than the first power, that is, the target charging power is low power, and the first application does not need to switch to display the low-power charging icon when the low-power charging icon is the same as the initial charging icon.

Currently, chargers can be classified into a fast charger and a slow charger, and the fast charger can shorten the charging time of the electronic device 100.

When the electronic device 100 charges the battery on the electronic device 100 through the charger 200, the charger 200 charges the battery of the electronic device 100 with the initial power before determining that the charger 200 is a fast charger or a slow charger. At the same time, the electronic device 100 displays an initial charge icon.

Thereafter, the charger 200 may communicate with the electronic device 100 in a protocol to determine whether the charger 200 is a fast charger or a slow charger.

Based on the protocol communication, the electronic device 100 may obtain the charging power supported by the charger 200. If the charging power is greater than the preset power, it may be determined that the charger 200 is a fast charger, and the charger 200 is switched to the high power to charge the battery on the electronic device 100. Thereafter, the electronic device 100 switches to display the high power charging icon.

If the charging power is less than the preset power, it may be determined that the charger 200 is a slow charger, and the charger 200 charges the battery on the electronic device 100 with low power. The electronic device 100 continues to display the low power charge icon.

However, the current speed at which the electronic device 100 switches to displaying either a high power charge icon or a low power charge icon may be slow. Resulting in the electronic device 100 not updating the high power charge icon or the low power charge icon in time. In particular, reference may be made to the description in the embodiment of fig. 8 and 9.

Based on the above, the application provides a charging icon display method, which comprises the following steps: after the charger 200 switches to high power to charge the battery on the electronic device 100, the electronic device 100 actively reports the high power charging event to the layer application, and the layer application switches to display the high power charging icon in time after receiving the high power charging event. In this way, the speed at which the electronic device 100 switches to displaying the high power charging icon can be quickly increased.

In one possible implementation, the charging power of the fast charger is greater than the charging power of the non-fast charger. Under the condition of the same charging voltage, the charging power of the quick charger is larger than that of the non-quick charger, and the charging current of the quick charger is larger than that of the non-quick charger, so that the charging time of the quick charger is shorter.

In other possible implementations, the charging power of the fast charger is greater than the charging power of the non-fast charger. Under the condition of the same charging current, the charging power of the quick charger is larger than that of the non-quick charger, and the charging voltage of the quick charger is larger than that of the non-quick charger, so that the charging time of the quick charger is shorter.

In other possible implementations, the charging power of the fast charger is greater than the charging power of the non-fast charger. Under the condition that the charging current and the charging voltage are not fixed, the charging power of the quick charger is larger than that of the non-quick charger, and the charging current and the charging voltage of the quick charger are larger than those of the non-quick charger, so that the charging time of the quick charger is shorter.

In order to distinguish between a fast charger charging scenario and a slow charger charging scenario, a charging icon displayed by the electronic device 100 when the fast charger charges the electronic device 100 is different from a charging icon displayed by the electronic device 100 when the slow charger charges the electronic device 100.

After the first application obtains the target power charging information, the first application may obtain the high power charging icon from the target power charging information, and display the high power charging icon.

By way of example, how the electronic device 100 displays the high power charging icon may refer to the description in the embodiments of fig. 4D and 4E, and the present application will not be described in detail herein.

Fig. 9 shows a timing diagram of a first application acquiring target power charging information.

Illustratively, the time difference between two adjacent heartbeats may be 60s, requiring a uevent event to be sent before the heartbeat information is sent. The time difference between two adjacent uevent events may also be 60s. As shown in fig. 9, the battery drive sends a uevent event to the first application over the communication interface at time ts.

However, as shown in fig. 9, if the charger 200 and the battery drive negotiate the charging protocol at time (t+185) s, a high power charge is determined. Since the charging driver has sent a uevent event to the communication interface at time (t+180) s. Since the heartbeat period is 60s, the charging drive needs to send a uevent event once more at time (t+240) s.

That is, the charging driver determines that the high power charging is performed at time (t+185) s, and needs to wait for sending a uevent event to the communication interface at time (t+240) s, where the uevent event is used to instruct the communication interface to acquire the target power charging information. If at the time (t+240) s, the charging driver sends a uevent event to the communication interface, and at the time (t+243) s, the charging driver sends target power charging information to the communication interface.

That is, if the charging driver has sent a uevent event to the communication interface to report the heartbeat information to the first application shortly before the charging protocol is negotiated and the high-power charging is determined, the charging driver needs to wait for the next period of the heartbeat information to arrive and then send the uevent event again to report the target power charging information to the first application, and if the period time of the heartbeat information is longer, the first application will not update the high-power charging icon in time, so that the user experience is affected.

Fig. 10 is a schematic diagram of how an electronic device 100 displays charging icons according to the present application.

As shown in fig. 10, first, the charger 200 negotiates a charging protocol with the electronic device 100 to determine the charging power.

The electronic device 100 then compares the charging power with the mobility threshold to determine the charging type.

In the event that the charging power is greater than the power threshold, the electronic device 100 may determine a high power charging icon and display the high power charging icon.

In the event that the charging power is less than the power threshold, the electronic device 100 may determine a low power charging icon and display the low power charging icon.

And S1101, finishing negotiation of a charging protocol, and determining the charging type and the target charging power by the charging drive.

As known from S506, the charging protocol is used to determine the charging type of the charger 200 and the target charging power.

The charge type may include a low power charge type and a high power charge type.

After determining the charging power, the charger 200 charges the battery on the electronic device 100 with the charging power. For how the charging drive and charger 200 negotiates the electric type and the target charging power, reference may be made to the description in S506, and the present application will not be repeated here.

S1103, in response to the update charge type icon message two, the battery drive saves the target power charge information.

As known from S1101, the charge type may include a low power charge type and a high power charge type.

In the case where the charging type is a low power charging type, the target power charging information includes, but is not limited to, one or more of the following: the remaining power of the electronic device 100, the state of charge of the electronic device 100, the target charging voltage, the target charging current, the low power charging icon, and the like.

In the case where the charging type is a high power charging type, the target power charging information includes, but is not limited to, one or more of the following: the remaining power of the electronic device 100, the state of charge of the electronic device 100, the target charging voltage, the target charging current, the high power charging icon, and the like. The state of charge of the electronic device 100 includes, but is not limited to, any of the following; an underfill state of charge, an uncharged state, and a full state.

S1104, the charging drive needs to determine whether the charging type is a low-power charging type or a high-power charging type.

In the case where it is determined that the charge type is the low power charge type, S1105 is performed.

In the case where it is determined that the charge type is the high-power charge type, S1106-S1111 are performed.

S1105, execution S804-S809.

And under the condition that the charging type is determined to be a low-power charging type and the low-power charging icon is the same as the initial charging icon, the effect of displaying the initial charging icon by the first application is consistent with the effect of displaying the low-power charging icon by the first application. The initial charge icon may be switched to display a low power charge icon as per the method of S1106-S1111. The charging driver is not required to generate a uevent event additionally according to the method of S1106-S1111. Power consumption can be saved.

In other embodiments, when it is determined that the charging type is a low-power charging type and the low-power charging icon is the same as the initial charging icon, the effect of the first application displaying the initial charging icon is consistent with the effect of the first application displaying the low-power charging icon. The first application may not update the charge icon and the process ends.

In other embodiments, when it is determined that the charging type is a low-power charging type and the low-power charging icon is different from the initial charging icon, the effect of displaying the initial charging icon by the first application is different from the effect of displaying the low-power charging icon by the first application, and the first application needs to switch the initial charging icon to display the low-power charging icon. To avoid the problem of not updating the low power charging icon in time like the embodiments of fig. 8 and 9, the method of S1106-S1111 may be switched to display the low power charging icon. Specifically, reference may be made to the descriptions in S1106-S1111, and the present application will not be repeated here.

And S1106, the charging driver sends a callback notification message to the battery driver.

In response to determining that the charge type is a high power charge type, the charge driver sends a callback notification message to the battery driver. The callback notification message is used to cause the battery driver to send a uevent event to the communication interface.

In some embodiments, S1104 may not be executed, and after the charger 200 negotiates with the charging driver to determine the charging type and the target charging power, the charging module may directly execute S1106 without determining whether the charging type is a high-power charging type or a low-power charging type, i.e. the ue event is repeated for one time, without waiting for the next heartbeat information period to come, so that the first application may acquire the target power charging information in time.

S1107, the battery driver sends a uevent event to the communication interface.

In response to the callback notification message, the battery driver may send a uevent event to the communication interface so that the communication interface may obtain the target power charging information.

In this way, after determining the high-power charging type, the electronic device 100 may actively send the uevent event to the communication interface through the battery driving, so that the communication interface and the stress layer may timely obtain the target power charging information.

S1108, the communication interface sends a message for acquiring the target power charging information to the battery driver.

In some embodiments, the message sent by the communication interface to the battery drive in S1108 to obtain the target power charging information may be referred to as a first message.

Illustratively, the time difference between two adjacent heartbeats may be 60s, requiring a uevent event to be sent before the heartbeat information is sent. The time difference between two adjacent uevent events may also be 60s. As shown in fig. 12, the battery drive sends a uevent event to the first application over the communication interface at time ts. The battery drive sends a uevent event to the first application over the communication interface at time (t+60) s. The battery drive sends a uevent event to the first application over the communication interface at time (t+120) s. The battery drive sends a heart event to the first application via the communication interface at time (t+180) s. The battery drive sends a uevent event to the first application over the communication interface at time (t+240) s.

As shown in fig. 12, if the charger 200 and the battery drive negotiate the charging protocol at time (t+185) s, a high power charge is determined. Since the charging driver has sent a uevent event to the communication interface at time (t+180) s. Since the heartbeat period is 60s, the charging drive needs to send a uevent event once more at time (t+240) s.

In order to reduce the time that the charging driver waits to send the next uevent event, and also to shorten the time that the first application switches to displaying the high-power charging icon, after the charger 200 and the battery driver negotiate the charging protocol at time (t+185) s, the charging driver may not wait to send the uevent event once at time (t+240) s, and actively send the uevent event once after the charging protocol negotiation is completed, for example, the battery driver may send the uevent event to the communication interface once in addition at time (t+186) s. Then, the battery driver may receive a message for acquiring the target power charging information transmitted by the communication interface, and in response to the message for acquiring the target power charging information transmitted by the communication interface, the battery driver may transmit the target power charging information to the communication interface at time (t+189) s. After receiving the target power charging information, the communication interface sends the target power charging information to the first application, and the first application can acquire the target power charging information and acquire the high-power charging icon from the target power charging information. The first application may switch to displaying the high power charging icon at time (t+198) s.

Compared with fig. 9, the time for switching the first application to display the high-power charging icon is shortened, and the step ensures that the first application is timely switched to display the high-power charging icon.

In some embodiments, to avoid the first application from continuously displaying the initial charge icon in fig. 11 due to information loss or other reasons. After the first application monitors that the time for displaying the initial charging icon exceeds the first time, the first application can actively send a message for acquiring the target power charging information to the battery driver so as to determine whether to continue displaying the initial charging icon or switch to displaying the high power charging icon or the low power charging icon.

In some embodiments, the method steps shown in fig. 13 may not be performed if the first application has switched to display a high power charge icon or a low power charge icon.

In some embodiments, the first application in S1301 sends a message to the communication interface to obtain the target power charging information, which may be referred to as a second message.

After the first application monitors that the time for displaying the initial charging icon exceeds the first time, the first application can send a message for acquiring the target power charging information to the communication interface in order to confirm whether to continue displaying the initial charging icon or switch to displaying the high power charging icon or the low power charging icon.

S1302, the communication interface sends a message for acquiring the target power charging information to the battery driver.

In response to the message sent by the first application to obtain the target power charging information, the communication interface sends the message of the target power charging information to the battery drive.
