Abstract
In this paper, the impact of Suspend/Resume mechanism on the power consumption of smartphone is investigated. When the operating system (OS) is in suspend mode, many trivial (less urgent) network packets will always wake up system, making OS frequently switch from suspend mode to resume mode, thus causing a high power consumption. Based on this observation, an novel optimization mechanism was proposed to delay wake-up system and prolong the duration of suspend mode so as to reduce power consumption. This novel method not only reduces the power consumption of WiFi components, but also reduces the power consumption of the total components. To verify the effectiveness of the novel mechanisms, we implemented such proposed mechanism on Huawei P8 platform, and carried out relevant experiments. The results showed that the proposed mechanism can effectively decrease power consumption by more than 7.63%, which indicates the feasibility of the proposed mechanism.
