Today, consumers use a smartphone device to display the media contents for work and entertainment purposes, as well as watching online video. Online video streaming is the main cause that consume smartphone’s energy quickly. To overcome this problem, smartphone’s energy management is crucial. Thus, a hybrid energy-aware profiler is proposed. Basically, a profiler will monitor and manage the energy consumption in the smartphone devices. The hybrid energy-aware profiler will set up a protocol preference of both the user and the device. Then, it will estimates the energy consumption in smartphone. However, saving energy alone can contribute to the Quality of Experience (QoE) neglection, thus the proposed solution takes into account the client QoE. Even though there are several existing energy-aware profilers that have been developed to manage energy use in smartphones however, most energy-aware profilers does not consider QoE at the same time. The proposed solution consider both, the performance of the hybrid energy-aware profiler is compared with the baseline energy models against a variation of content adaptation according to the pre-defined variables. Three types of variables were determined; resolution, frame rate and energy consumption in smartphone devices. Then, using QoE subjective surveys, Mean Opinion Score (MOS) of users is obtained from survey experiment on QoE. Summary of the experiment result display the significant reduce 14.5% energy consumption by using hybrid energy-aware profiler than generic profiler. Next, the minimum QoE and Quality of Services (QoS) maximum value is measured to generate a list of possible video adaptation attributes requirements. The list is essential to help developer deciding which suitable alternative video streaming media format can be placed in the servers. Also, the list is aimed to help users to choose the suitable video format in order to save energy in their smartphone devices.
