This document summarizes a study on factors influencing the quality of experience (QoE) of mobile applications. The study collected both qualitative and quantitative data from 31 smartphone users over 4 weeks. Key findings include: (1) Battery life, application performance, and network connectivity were found to strongly influence QoE. (2) Location, social context, and routine activities helped determine when and how apps were used. (3) Streaming multimedia apps had the lowest QoE, likely due to variations in network quality and bandwidth. The study provides initial insights into real-world factors affecting user experience with mobile apps and networks, but more rigorous analysis is needed.
