This document proposes a predictive battery saver app called Optimizer that uses deep learning techniques to provide personalized recommendations for improving battery life. It analyzes user behavior and app usage data to predict battery drain and offers tailored suggestions without running constantly in the background. Both free and premium versions are suggested, with the premium version costing $0.99 annually. Revenue would come from the premium subscriptions and sharing anonymous user data with collaborators. The goal is to help the 1.6 billion smartphone users worldwide extend battery life through a scientific, non-intrusive approach.
