Energy Management Systems and Smart Phones: A Systematic Literature Survey

Smartphones are a crucial necessity in people’s lives nowadays. Many smartphone hardware components (i.e., CPU, Wi-Fi, etc…) are in rapid development, improving their performance. However, battery technology has not been able to keep up with this pace of development where battery life becomes shorter and shorter with every new update. Therefore, smartphone energy management has become very important and has been studied by many researchers. In this research paper, we conducted a Systematic Literature Review (SLR) to review the research contribution made in the field of smartphone Energy Management Systems (EMS). We analyzed 72 relevant papers and grouped them into two categories: 1) energy management techniques that reduce or limit energy consumption, and 2) smartphone energy assessments that focus on analyzing energy consumption by smartphone components. Then, we found that mobile application was the most studied smartphone module followed by network and operating system. Around 29 studies built their solution on Android which shows the importance of open source. Finally, the study highlights the research gap in power management for closed source systems and drivers as well as specific hardware modules.
