Mobile devices and applications have been very popular in people's daily life. However, the energy issue in mobile platform, or in other words, the quick use-out of battery, has been rather a bottle-neck for the further development of mobile applications, as modern mobile applications usually cost a lot of power in mobile devices. Thus, it has been an urgent need to develop energy-friendly techniques for mobile applications. The most important thing is to identify the major factors that cause the rapid decreasing of power in mobile applications. In this paper, we make a preliminary study on this issue, and conduct experiments on mobile platform to analyse the connection between query types and energy consumption. On this basis, we can identify the most energy-consuming queries in mobile applications. In detail, we choose the TPC_H benchmark as the basic workload and select different types of queries to see the relationship between query type and energy consumption in mobile applications. The results show that the energy consumption in mobile applications is sensitive to high-cost queries. This indicates that there should be query-dependant methods to improve the energy efficiency in mobile applications.
