The invention provides a mobile phone temperature and power consumption detection experimental system and a detection method thereof. A robot manual operation module is used for simulating the operation of the fingers of a user on a mobile phone screen, and is controlled to finish a whole set of operation processes via graphics recognition; an operation box is used for setting the robot manual operation module, a mobile phone bracket, a high-definition high-speed video camera and a detection module; the mobile phone bracket is used for fixing a mobile phone to be tested in the operation box; an infrared imaging instrument can be used for accurately capturing the small change of the temperature of the mobile phone to be tested, and performing analysis and processing; and the detection module is used for controlling the robot manual operation module, and giving a mobile phone temperature rising comfort evaluation report specific to the temperature rising comfort of the mobile phone to be tested. The temperature rising situation of each side of the mobile phone under various operation instances are detected at different environmental temperatures, and a temperature profile of mobile phone temperature stabilization time, a highest temperature and highest temperature time and a temperature comfort evaluation report are given.
