Interaction based charging control is described. In an embodiment, a device is described, comprising: an interface configured to receive a charging power from another device; a sensor configured to detect interaction of the device; a charging controller configured to reduce the charging power in response to the detected interaction; in response to the reduced charging power, a processor configured to allow more processing power for the device. In other embodiments, a device comprising a sensor configured to detect a temperature of the device, and a method are discussed.
