The second electronic device may receive the detection signal sent by the first electronic device, and the second electronic device may send a response signal corresponding to the detection signal to the first electronic device; under the condition that the first electronic device receives the response signal, the first electronic device and the second electronic device can be in radio connection through electromagnetic coupling, and under the condition that wireless point connection is established between the first electronic device and the second electronic device, the first electronic device and the second electronic device can be charged mutually.

In the above, the first electronic device is taken as an example to transmit the probe signal to the second electronic device, and in other scenarios, the second electronic device may also transmit the probe signal to the first electronic device, and the present embodiment is not limited specifically.

Step 302, the first electronic device determines a first usage duration of the remaining power of the first electronic device;

specifically, in this embodiment, the first electronic device may obtain the remaining power of the first electronic device and the working current of the first electronic device, and the first electronic device may determine the first usage duration of the remaining power of the first electronic device according to the remaining power of the first electronic device and the working current of the first electronic device.

In this embodiment, a specific process of how the first electronic device determines the first usage duration according to the remaining power of the first electronic device is not limited, as long as the first electronic device can determine the first usage duration, and several optional implementation manners of determining the first usage duration by the first electronic device are exemplarily described as follows:

mode 1

In this mode, the first electronic device obtains the current working current of the first electronic device, and the first electronic device can determine a first usage duration according to formula 1:

equation 1: the first service life is the residual capacity of the first electronic device/the current working current of the first electronic device 60;

the unit of the first usage time period may be minutes (min), the unit of the remaining capacity of the first electronic device may be milliampere hours (mAh), and the unit of the current operating current of the first electronic device may be milliamperes (mA).

Mode 2

In the present mode, the first electronic device obtains a variation of a first battery capacity of the first electronic device within a first time period determined by the first electronic device;

for example, if the first electronic device determines that the current time is 13:30, the time start point of the first time period may be time 12:00, and the time end point of the first time period may be 13:30, the first electronic device may obtain a variation of the first battery capacity of the first electronic device in the first time period (12:00 to 13: 30).

The first electronic equipment determines a first use duration according to a formula 2:

equation 2: the first use time period is the residual capacity of the first electronic equipment/the variation of the battery capacity in the first time period;

wherein the first usage time period and the first time period may be in minutes (min), and the remaining capacity of the first electronic device may be in milliampere hours (mAh).

In this embodiment, the duration of the first time period is not limited, for example, the duration of the first time period may be 60min, or 5 min.

Mode 3, in mode 2, the first time period determined by the first electronic device is a time period before the current time of the first electronic device, and in mode 3, the first electronic device may estimate a change amount of a battery capacity of the first electronic device at a future time, so as to estimate the first usage time period;

the specific execution flow can be seen in the following steps:

step A1, the first electronic device obtains a second time period, and the time starting point of the second time period is the current time or the time after the current time;

for example, if the first electronic device determines that the current time is 13:00, the first electronic device may determine that the time starting point of the second time period is 13:00, or may be 13:30, and so on, as long as the time starting point of the second time period is located at the current time or a time after the current time;

in this embodiment, the duration of the second time period is not limited, for example, the duration may be 60min, and for example, the duration may be 10min, and specifically, the present embodiment is not limited, and the example that the duration of the second time period is 60min is taken as an example to exemplarily describe:

step A2, the first electronic device obtains a corresponding third time period according to the second time period, wherein the starting time and the ending time of the third time period are the same as the starting time and the ending time of the second time period, and the date of the third time period is earlier than the date of the second time period;

in the above example, the second time period determined by the first electronic device may be 13:00-14:00, and the date of the second time period is the current date, that is, the date of the first electronic device executing the method shown in this embodiment, where the date shown in this embodiment refers to the year, month and day, such as 6/month and 20/year 19, that is, the first electronic device has a need to perform mutual charging with the second electronic device in 6/month and 20/year 19;

the third time period determined by the electronic device is between 13:00 and 14:00, and the date of the third time period is earlier than the date of the second time period, in the above example, the date of the second time period is 19 years, 6 months and 20 days, and the date of the third time period may be 19 years, 6 months, 19 days, and the like, and is not limited in this embodiment as long as the date of the third time period is earlier than the date of the second time period.

Step A3, the first electronic device obtains a variation of a second battery capacity of the first electronic device in a third time period;

under the condition that the first electronic device determines the third time period, the first electronic device can count the variation of the second battery capacity of the first electronic device in the third time period;

optionally, because the variation amounts of the second battery capacities in the third time periods on different dates are different, the first electronic device may generate a target list according to the variation amounts of the second battery capacities in the third time periods on different dates, the target list is sorted according to priorities of the second battery capacities from large to small, the first electronic device obtains the variation amount of the second battery capacity in the target list at the highest priority, and the first electronic device determines step a4 according to the third time period with the highest priority;

step a4, the first electronic device determines the operating current according to the variation of the second battery power and the third time period.

Specifically, the first electronic device may calculate the working current according to formula 3;

equation 3: the working current of the first electronic device is the change of the battery capacity in the third time period;

the unit of the third time period may be minutes (min), and the unit of the variation of the battery capacity in the third time period may be milliampere-hours (mAh).

Step a5, the first electronic device determines the first usage duration according to the working current, and specifically, the first electronic device may calculate the first usage duration according to formula 4 shown below;

equation 5: the first service life is equal to the residual capacity/the working current of the first electronic equipment;

the operating current is the operating current obtained by step a4 for a first period of use.

Step 303, the first electronic device receives, from a second electronic device, a second usage duration of the remaining power of the second electronic device;

for the specific process of determining the second duration by the second electronic device, please refer to the specific process of determining the first duration by the first electronic device in detail, which is not described in detail in this embodiment.

Step 304, the first electronic device determines whether the first duration of use is greater than the second duration of use, if so, step 305 is executed, and if not, step 306 is executed.

In order to enable the charging method shown in this embodiment to implement mutual charging between the first electronic device and the second electronic device without manual operation of a user, the first electronic device is required to determine that the electronic device serving as a power supplier and the electronic device serving as a power receiver are located between the first electronic device and the second electronic device, and the specific determination process is as follows:

the first electronic device can judge whether the first use duration is longer than the second use duration, if the first use duration is longer than the second use duration, it is indicated that the normal use duration of the first electronic device is longer than the normal use duration of the second electronic device, and the first electronic device can be used as a power supplier to charge the second electronic device;

if the first usage duration is shorter than the second usage duration, it indicates that the duration in which the first electronic device can be normally used is shorter than the duration in which the second electronic device can be normally used, the first electronic device can be used as a power receiver, and the second electronic device charges the first electronic device.

Step 305, the first electronic device determines that the first electronic device is in a reverse charging mode.

In this embodiment, if the first electronic device determines that the first usage duration is longer than the second usage duration, the first electronic device may determine that the first electronic device is in a reverse charging mode, where the reverse charging mode is that the first electronic device outputs a charging current to the second electronic device, and thus the first electronic device is a power supplier at this time.

Step 306, the first electronic device determines that the first electronic device is in a forward charging mode.

In this embodiment, if the first electronic device determines that the first usage duration is less than the second usage duration, the first electronic device determines that the first electronic device is in a forward charging mode, where the forward charging mode is that the first electronic device receives a charging current output by the second electronic device, and thus the first electronic device is a power receiver at this time.

In this embodiment, the first electronic device may periodically detect a first usage duration of the first electronic device, and the first electronic device periodically receives a second usage duration sent by the second electronic device, and then the first electronic device may periodically perform the above-mentioned steps 302 to 305, for example, in a first charging period, if the first usage duration is greater than the second usage duration, the first electronic device charges the second electronic device, and in a second charging period, if the first usage duration is less than the second usage duration, the second electronic device charges the first electronic device.

The method shown by the embodiment has the advantages that:

the power supplier and the power receiver are judged through the use duration, so that the use degree of the electronic equipment is fully considered in the process of determining the power supplier and the power receiver, for example, although the residual capacity of the electronic equipment is relatively large, the electronic equipment runs a plurality of applications with large power consumption, namely, the use degree of the electronic equipment is very heavy, if the electronic equipment is used as the power supplier to supply power to other electronic equipment, the situation that the electronic equipment cannot be used normally subsequently can be caused, and by adopting the method shown in the embodiment, the power supplier and the power receiver are determined through the use duration, the situation that the electronic equipment with the heavy use degree supplies power to the electronic equipment with the light use degree is avoided, and the normal use of the electronic equipment is effectively ensured.
