Regulating charging port attach and detach

An electronic device configured to receive a charging current from a charging port, the device comprising:

• a charger system, configured to automatically detect a detach from the charging port;
• the charger system further configured to lower a current limit associated with the charging current;
• and
• the charger system further configured to:
• if during a predetermined wait time an attach to the charging port is detected, then ignore the detach from the charging port and allow the charging current to charge the electronic device at the lower current limit associated with the charging current;
• and
• if during the predetermined wait time the attach to the charging port is not detected, then initiate a charging port detach process.

A smartphone configured to receive a charging current from a charging port, the smartphone comprising:

• a USB controller configured to enable data communication with another device;
• a charger system, configured to automatically detect a detach from the charging port;
• the charger system further configured to lower a current limit associated with the charging current;
• the charger system further configured to:
• if during a predetermined wait time an attach to the charging port is detected, then ignore the detach from the charging port and allow the charging current to charge the smartphone at the lower current limit associated with the charging current, and
• if during the predetermined wait time the attach to the charging port is not detected, then initiate a charging port detach process;
• and
• the charger system further configured to provide to the USB controller information concerning at least whether the charging port is attached to the smartphone or whether the charging port is detached from the smartphone.
