Embodiments of the present invention disclose a method and an apparatus for controlling chip performance, and relate to the field of communications technologies, which solves a problem in the prior art that a chip is reset or performance is greatly decreased as long as a temperature of the chip is higher than a preset threshold. The method includes: obtaining a working temperature of a chip; when the working temperature of the chip reaches one of multiple preset temperature thresholds, obtaining, according to preset correspondence between a temperature threshold and a chip performance control policy, a chip performance control policy that corresponds to the one of the multiple temperature thresholds; and controlling working of the chip according to the control policy. The present invention is applicable to an electronic device to which a chip is applied, such as a desktop computer or a notebook computer.
