Power consumption of Android device using different video codecs: An analysis

Power is a critical factor for working of hand held devices. The video applications are one of the widely used functionality of hand held devices and are prime factor for deciding the usability of product. These video applications are consists of complex algorithmic operations which depend on codec used for video. Because of difference in complexity these codecs, the power consumption is also different. The work presented here analyzes the power consumption for different video codec for same video on Android device. It gives the better view of power consumption for the device running on battery as power model used for calculation computes the power consumed in mAh unit. The results show that the video codecs in descending order of their power consumption are DivX, MPEG 4, H 264, and Xvid.
