Selecting a charging mode for charging a battery of a portable device

A portable device comprising:

• a memory;
• a battery;
• a port for connecting a charging device to the portable device;
• a processor that is coupled to the memory and which generates a plurality of processing modules comprising a charging management module that configures the processor to perform charging management measures, wherein:
• the charging management module:
• detects a coupling of the charging device to the port;
• determines a set of charging modes that are supported by the charging device;
• identifies whether the set of charging modes includes a particular charging mode;
• in response to identifying that the set of charging modes includes the particular charging mode, issues a first notification to the charging device that identifies the particular charging mode and that, when received by the charging device, triggers the charging device to operate in the particular charging mode, wherein the particular charging mode establishes at least one particular electrical current to be used for charging the battery;
• and
• in response to determining the set of charging modes does not include the particular charging mode, selects an alternate charging mode from among the set of charging modes supported by the charging device.

A computer program product comprising:

• a computer readable storage device;
• and
• program code on the computer readable storage device that when executed by a processor associated with a portable device, the program code enables the device to provide the functionality of:
• detecting a coupling of a charging device at a portable device having a battery;
• determining a set of charging modes that are supported by the charging device;
• identifying whether the set of charging modes includes a particular charging mode;
• in response to identifying that the set of charging modes includes the particular charging mode, issuing a first notification to the charging device that identifies the particular charging mode and that, when received by the charging device, triggers the charging device to operate in the particular charging mode, wherein the particular charging mode establishes at least one particular electrical current to be used for charging the battery;
• and
• in response to determining the set of charging modes does not include the particular charging mode, selecting an alternate charging mode from among the set of charging modes supported by the charging device.
