In a specific implementation, different battery charging processing strategies may be determined for different battery performances due to different internal structures or components of different batteries, and the electronic device may obtain a first performance parameter of a first battery and a second performance parameter of a second battery, where if a first remaining power corresponding to the first performance parameter is less than a first preset power and a second remaining power corresponding to the second performance parameter is greater than or equal to the second preset power, it may be understood that the first remaining power of the first battery is insufficient to maintain normal operation of the electronic device, and the second remaining power of the second battery is sufficient, then the first battery may be charged, and further, due to different battery temperatures, charging efficiency of the battery may affect the life of the battery, for example, if the battery is still charged with a high-power charging power, the life of the battery may be damaged, and at the same time, the battery may explode, therefore, different charging powers may be preset for different battery temperatures, and the battery may be charged according to a suitable charging power, and specifically, the first charging power of the first battery may be obtained, and the first charging power of the first battery may be determined according to a first charging target temperature of the first battery.

Finally, if the first remaining capacity is less than the first preset capacity and the second remaining capacity is less than the second preset capacity, or if the first remaining capacity is greater than or equal to the first preset capacity and the second remaining capacity is greater than or equal to the second preset capacity, it indicates that neither the first battery nor the second battery meets the preset condition at the moment, and both the first battery and the second battery need to be charged, therefore, the electronic device can preset a mapping relationship between a ratio of evaluation values and a charging distribution rate, and can perform evaluation according to the performance parameters of the two different batteries to obtain two target evaluation values, obtain the charging distribution rates corresponding to the two batteries according to the two target evaluation values, and perform charging processing on the two batteries according to the charging distribution rate, in a specific implementation, the first performance parameter and the second performance parameter can be evaluated respectively, and a specific evaluation mode is not limited herein, for example, different remaining power intervals may be preset, different power weights may be preset for the different remaining power intervals, all power weight sums are 1, rated voltages may be preset for the different intervals, different voltage weights may be preset for the rated voltages of the different intervals, all voltage weight sums are 1, different charge and discharge frequency intervals may be preset, different charge and discharge weights may be preset for the different charge and discharge frequency intervals, all charge and discharge weight sums are 1, different capacity weights may be preset for the different battery capacities, and all capacity weight sums are 1, so that a first remaining power, a first rated voltage, a first charge and discharge frequency, and an interval corresponding to the first battery capacity corresponding to the first battery may be obtained, different weights may be obtained, and finally all weights may be added to obtain the first target evaluation value, finally, a charging distribution rate may be preset according to a ratio of different evaluation values, for example, a target ratio between the first target evaluation value and the second target evaluation value is 1:2, and then the charging distribution rate is 1:2, that is, the charging efficiency of the second battery may be twice that of the first battery, or the input current of the second battery may be twice that of the first battery, and so on, according to a mapping relationship between the ratio of the preset evaluation values and the charging distribution rate, which is not limited herein, so that the charging distribution rate may be determined according to actual conditions of different batteries, and the charging efficiency may be improved.
