Abstract

An electronic device comprises a processor, a charging port, and memory that stores program code. When the program code is executed by the processor, the electronic device charges a battery of the electronic device using the charging port when a charger is connected to the charging port, stops charging in response to detecting that the charging port is abnormal, and displays a first window on a display interface of the electronic device in response to detecting that the charging port is abnormal. The first window comprises a first prompt information and a second prompt information. The first prompt information is used to prompt that liquid intake exists in the charging port, and the second prompt information is used to prompt a user to exclude a liquid intake situation of the charging port.

First claim

What is claimed is:

1. An electronic device, comprising:
a battery;
a display interface;
a charging port;
a memory configured to store program code; and
a processor coupled to the battery, the display interface, the charging port, and the memory and configured to execute the program code to cause the electronic device to:
charge the battery using the charging port when a charger is connected to the charging port;
stop charging the battery in response to detecting that the charging port is abnormal; and
display a first window on the display interface in response to detecting that the charging port is abnormal,
wherein the first window comprises first prompt information and second prompt information,
wherein the first prompt information prompts that liquid is in the charging port, and
wherein the second prompt information prompts a user to address liquid intake in the charging port.

2. The electronic device of claim 1 , wherein the first window further comprises third prompt information that prompts that the electronic device is disconnected from charging.

3. The electronic device of claim 1 , wherein the charging port comprises a universal serial bus (USB) port.

4. The electronic device of claim 1 , wherein the first window further comprises a first option, and wherein the processor is further configured to execute the program code to cause the electronic device to charge the battery using the charging port in response to an operation on the first option.

5. The electronic device of claim 1 , wherein the charging port is abnormal when at least one of a charging current, a charging voltage, or a temperature of the electronic device is greater than a threshold.

6. The electronic device of claim 1 , wherein a leakage current exists in a charging process of the electronic device, and wherein the second prompt information indicates that the liquid is in the charging port.

7. The electronic device of claim 4 , wherein the first option is a cancel option.

8. The electronic device of claim 7 , wherein the electronic device is a mobile phone, a tablet computer, or a wearable device.

9. The electronic device of claim 1 , wherein the processor is further configured to execute the program code to cause the electronic device to generate a circuit control command to continue charging the battery.

10. A method for detecting liquid intake and implemented by an electronic device, wherein the method comprises:
charging a battery of the electronic device using a charging port of the electronic device when a charger is connected to the charging port;
stopping charging the battery in response to detecting that the charging port is abnormal; and
displaying a first window on a display interface of the electronic device in response to detecting that the charging port is abnormal,
wherein the first window comprises first prompt information and second prompt information,
wherein the first prompt information prompts that liquid is in the charging port, and
wherein the second prompt information prompts a user to address liquid intake in the charging port.

11. The method of claim 10 , wherein the first window further comprises third prompt information that prompts that the electronic device has been disconnected from charging.

12. The method of claim 10 , wherein the charging port comprises a universal serial bus (USB) port or a Lightning port.

13. The method of claim 10 , wherein the first window further comprises a first option, and wherein the method further comprises continuing to charge the battery through the charging port in response to an operation on the first option.

14. The method of claim 10 , wherein the charging port is abnormal when at least one of a charging current, a charging voltage, or a temperature of the electronic device is greater than a threshold.

15. The method of claim 10 , wherein a leakage current exists in a charging process of the electronic device, and wherein the second prompt information indicates that the liquid is in the charging port.

16. The method of claim 13 , wherein the first option is a cancel option.

17. The method of claim 16 , wherein the electronic device is a mobile phone, a tablet computer, or a wearable device.

18. The method of claim 10 , further comprising generating a circuit control command to continue and enable charging the battery.

19. The electronic device of claim 1 , wherein the charging port comprises a Lightning port.

20. A computer program product comprising instructions that are stored on a computer-readable medium and that, when executed by a processor, cause an electronic device to:
charge a battery of the electronic device using a charging port of the electronic device when a charger is connected to the charging port;
stop charging the battery in response to detecting that the charging port is abnormal; and
display a first window on a display interface of the electronic device in response to detecting that the charging port is abnormal,
wherein the first window comprises first prompt information and second prompt information,
wherein the first prompt information prompts that liquid is in the charging port, and
wherein the second prompt information prompts a user to address liquid intake in the charging port.
