The COVID-19 pandemic has accelerated the adoption of online education, including mobile-assisted language learning (MALL). Extensive research has examined various aspects of MALL; there remains a gap in understanding the preferred mobile resources that promote lifelong learning ability, particularly in relation to gender differences. This study focuses on Chinese EFL learners' preferences for mobile resources in promoting lifelong learning. Employing a quantitative questionnaire, the researchers examine the relationship between mobile learning efficacy and lifelong learning ability. The findings indicate no significant differences in mobile resource preferences among male and female students. However, a moderately positive relationship between mobile learning efficacy and lifelong learning ability was discovered. Notably, this study identifies that Chinese EFL students preferred mobile resources that may act as a platform to enhance mobile learning efficacy and support lifelong learning.
