Evaluating Mobile Framework Energy Efficiency: A Comparative Analysis of React Native, Flutter and Native Architectures

This thesis analyzes the energy efficiency of modern cross-platform frameworks compared to native development, evaluating the impact of different architectural choices on battery consumption in mobile devices. Through an empirical study based on a custom "No-UI" methodology, designed to isolate display-related hardware variables, 17 features representative of the current digital market were profiled. The research compared the performance of Swift and Kotlin with the most recent architectural evolutions of React Native and Flutter on iOS and Android ecosystems. Using professional analysis tools such as Xcode Instruments and Android Studio Profiler, the work quantifies the computational overhead introduced by abstraction layers. The results obtained define the trade-off between abstraction and efficiency, providing developers with concrete data to guide future technological choices towards high-performance and eco-sustainable mobile development.
