Energy efficient use of the smartphones : Student Survey for the Oulu University of Applied Sciences

As the number of smartphones and their users are swiftly increasing in the future, it is crucial to find various ways for using smartphones sustainably and energy efficiently. Nowadays the duration of the battery is limited because of its size and weight, which is why the energy efficient use of the smartphone is essential. Recently, the endurance of battery lifetime has been gaining popularity as a significant feature among smartphone users. The purpose of the thesis was to find out various methods of using smartphones in an energy efficient way. The thesis introduces the features of smartphone that can help manage battery consumption and analyses how smartphone user behaviour affects the battery consumption. Data for the thesis were collected from topic related literature, scientific articles, online sources and conducted research about the topic. With the survey, it was examined whether the respondents of the survey used their own smartphones energy efficiently. The respondents were students from different degree programmes in the Oulu University of Applied Sciences. As a result of the thesis it was discovered that smartphones have various features and functions that drain battery life. Furthermore, smartphones have many different settings that can assist with managing battery consumption. In addition, the way that smartphones battery is being charged affects profoundly the overall endurance of the battery. With the help of the survey essential information was gathered of user behavior and the efficiency of smartphone use. It was found out that even though the majority of the respondents knew how to use smartphones energy efficiently, several of the respondents were not necessarily doing so. There were also some notable differences when comparing the results of the survey between the replies of male and female respondents
