MoBateriE: A Personalised Profile-Based Intelligent and Adaptive Energy Manager

Abstract

Increasing electronic waste has forced the mobile phone industry to move into a new era of energy consumption awareness. Trends show that mobile phone manufacturers are implementing more and more features on a single device. Using these features has led to an increase in electricity consumed by mobile phones, thus forcing users to charge them more frequently. Studies have shown that one can maximise a phone's battery life by limiting the number of charging cycles (Columbus, 2013). In this study, a survey was conducted in order to collect mobile phone usage behaviour. Data concerning most frequently used mobile features together with their usage frequency were collected. Based on the information gathered, a mobile application, MoBateriE, was designed. This application consists of an expert system which at first studies users’ behaviour and later imitates them whenever needed. MoBateriE has been designed for smart phone users who want to make extensive use of the features available on their phones without exhausting the battery efficiency of the phone. This application was distributed to a large number of users. Usage logs of thirty-three users were collected and analysed. Results obtained show that after using MoBateriE, users enjoyed a four per cent increase in usage time per charging cycle.
