Abstract
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.
Highlights
We found most of the research works fall in this category, i.e., analysing and estimating the power consumption have been the topmost priority among smartphone energy research
An online algorithm, called Online seRvice caching for mobile Edge cOmputing (OREO) proposed by Xu et al [359], based on Lyapunov optimization, performs online stochastic dynamic service caching and task offloading to address the main problems of MEC, including service heterogeneity, unknown system dynamics, spatial demand coupling and decentralized coordination and can effectively lessen computation latency for end users with low energy consumption
There is a limitation of the battery capacity, which is determined by its chemical properties and cannot be increased beyond a certain limit
Summary
As per application requirements, many of the apps want rich contextual information which are acquired through different embedded sensors [192] These functionalities in a modern smartphone demand much more power compared to the feature phones with only basic capabilities such as voice calls and SMS [191]. To engineer energy-efficient mobile devices, efficient power consumption modelling, prediction, and optimization are needed for each component as well as for the whole unit This becomes even more challenging for smartphones with different architectures and platforms. Efficient power management and energy-efficient techniques and the adoption of green principles for smartphone batteries could be a great help in maintaining sustainability in smartphone usage [196] Acknowledging these two factors, monitoring power consumption and attempting energy-efficiency have always been among the hot research topics related to mobile computing and communication [197]. This paper aims to provide the readers with the state-of-the-art of the smartphone batteries by reporting the recent and future developments
