Constant power charging method and device for mobile terminal

A mobile terminal, comprising:

• a processor and a memory,
• wherein the memory stores computer programs, and the processor is configured to execute the computer programs to cause charging a rechargeable battery of the mobile terminal with a constant power,
• wherein the charging a rechargeable battery of the mobile terminal with a constant power comprises:
• charging the rechargeable battery of the mobile terminal with a first constant power determined based on an average charging power supported by the mobile terminal, when a maximum output power of a charger is greater than or equal to the average charging power supported by the mobile terminal, wherein the first constant power is equal to or smaller than the average charging power supported by the mobile terminal;
• and
• charging the rechargeable battery of the mobile terminal with a second constant power determined based on the maximum output power of the charger, when the maximum output power of the charger is less than the average charging power supported by the mobile terminal.

A chip, comprising:

• a programmable logic circuit and program instructions, wherein the chip is configured to, when operating, cause charging a rechargeable battery of a mobile terminal with a constant power,
• wherein the charging a rechargeable battery of the mobile terminal with a constant power comprises:
• charging the rechargeable battery of the mobile terminal with a first constant power determined based on an average charging power supported by the mobile terminal, when a maximum output power of a charger is greater than or equal to the average charging power supported by the mobile terminal, wherein the first constant power is equal to or smaller than the average charging power supported by the mobile terminal;
• and
• charging the rechargeable battery of the mobile terminal with a second constant power determined based on the maximum output power of the charger, when the maximum output power of the charger is less than the average charging power supported by the mobile terminal.
