Power Consumption Analysis, Measurement, Management, and Issues:A State-of-the-Art Review of Smartphone Battery and Energy Usage
The advancement and popularity of smartphones have made it an essential and all-purpose device. But lack of advancement in battery technology has held back its optimum potential. Therefore, considering its scarcity, optimal use and efficient management of energy are crucial in a smartphone. For that, a fair understanding of a smartphone's energy consumption factors is necessary for both users and device manufacturers, along with other stakeholders in the smartphone ecosystem. It is important to assess how much of the device's energy is consumed by which components and under what circumstances. This paper provides a generalized, but detailed analysis of the power consumption causes (internal and external) of a smartphone and also offers suggestive measures to minimize the consumption for each factor. The main contribution of this paper is four comprehensive literature reviews on: 1) smartphone's power consumption assessment and estimation (including power consumption analysis and modelling); 2) power consumption management for smartphones (including energy-saving methods and techniques); 3) state-of-the-art of the research and commercial developments of smartphone batteries (including alternative power sources); and 4) mitigating the hazardous issues of smartphones' batteries (with a details explanation of the issues). The research works are further subcategorized based on different research and solution approaches. A good number of recent empirical research works are considered for this comprehensive review, and each of them is succinctly analysed and discussed
Energy-Saving Strategies for Mobile Web Apps and their Measurement: Results from a Decade of Research (Preprint)
In 2022, over half of the web traffic was accessed through mobile devices. By
reducing the energy consumption of mobile web apps, we can not only extend the
battery life of our devices, but also make a significant contribution to energy
conservation efforts. For example, if we could save only 5% of the energy used
by web apps, we estimate that it would be enough to shut down one of the
nuclear reactors in Fukushima. This paper presents a comprehensive overview of
energy-saving experiments and related approaches for mobile web apps, relevant
for researchers and practitioners. To achieve this objective, we conducted a
systematic literature review and identified 44 primary studies for inclusion.
Through the mapping and analysis of scientific papers, this work contributes:
(1) an overview of the energy-draining aspects of mobile web apps, (2) a
comprehensive description of the methodology used for the energy-saving
experiments, and (3) a categorization and synthesis of various energy-saving
approaches.Comment: Preprint for 2023 IEEE/ACM 10th International Conference on Mobile

Efficient Solar Powered Smartphone for Nigeria’s Telecom Advancement
This study is aimed at producing an efficient model design of a solar-powered Smartphone that can be used continuously without the need to recharge their batteries from electrical outlets. There has been recent significant advancements in the research aimed at developing solar powered Smartphones as against the Smartphones we have today that requires frequent recharge of their batteries from electrical outlets. But these advancements have only produced solar Smartphone with efficiency of less than 19%. This study is theoretical due to lack of fund to produce the empirical design of the efficient solar powered Smartphone. However, it is intended to provide a new direction for Researchers in solar powered Smartphone Design to enable them produce efficient models that can continuously work for years without recharging their batteries.
