1. A method, comprising:

  • charging a battery of a device using a charging circuit that is coupled to a power supply;

    detecting a conductive contact on a capacitive touch interface of the device;

    measuring it level of noise on the capacitive touch interface in response to detection of the conductive contact;

    determining whether the level of noise exceeds a noise level threshold; and

    interrupting the battery charging, by isolating the charging circuit from the power supply, when the level of noise adversely affects performance of the capacitive touch interface by exceeding the noise level threshold.
