Embodiments disclosed herein pertain to power conservation for electronic devices. According to one embodiment, power conservation can be achieved through adaptive frame rate control for a display associated with an electronic device. The frame rate is able to be controlled so as to adapt to a frame rate that is adequate for the display task. Since the display often times displays content that is not very dynamic, the frame rate in such situations can be controlled to use a reduced frame rate, which thereby reduces power consumption. However, when the display displays content that is substantially dynamic, the frame rate in such situations can be controlled to use an enhanced (or not reduced) frame rate, which ensures reasonable display quality.
