Evaluation of Battery Usage and Scalability when Performing Parallel Applications on Mobile Devices

Abstract: The advances made in mobile and low-powered computing within the last decade has made mobility a key term of today, where one cannot imagine a daily life without a mobile phone. This is largely due to the availability of smaller and faster hardware, such as multi-core processors and high-speed mobile networks. However, heavy computations or applications performed on multiple cores can be very power consuming and as a result, leave the user with an unusable device. This thesis explores and measures the battery usage when performing parallel tasks on an Android device. This is done by developing an application and algorithm able to be executed on a chosen number of cores. The result is presented with both a system-wide battery usage as well as an app-specific battery usage of the developed application
