(1) Background: Problematic smartphone use in adolescents has become a major concern among parents and educators. This study aimed to determine the factors associated with, and the predictors of, low, average, and high perceived academic performance (PAP). (2) Methods: Descriptive and comparative analyses were employed in this cross-sectional study among 3374 Filipino high school students through an online Google forms survey. (3) Results: We found that age, grade level, father’s education, time spent daily on weekends, frequency of use on weekdays, purpose of use, nomophobia (NMP), and smartphone addiction (SA) were significantly associated with low PAP, while frequency of use on weekends and type of internet access had a significant association with high PAP. Gender was a significant predictor of low, average, and high PAP. Father’s education and SA were also significant predictors for both low and average PAP. (4) Conclusions: This study shows the significant association between personal profiles, family environment, patterns of smartphone use, NMP, and SA contributing to a significant impact on Filipino high school students’ PAP. This suggests that proper guidelines for smartphone use should be provided at home and in school settings to raise awareness of the adverse effects of SA on students’ academic performance.

菲律宾高中生在低，平均和高感知学业水平上的个人资料，家庭环境，智能手机的使用方式，恐惧症和智能手机上瘾

（1）背景：青少年使用智能手机存在问题已成为父母和教育者的主要关注点。这项研究旨在确定与低，平均和高感知学习成绩（PAP）相关的因素以及预测因素。（2）方法：本横断面研究通过在线Google表格调查对3374名菲律宾高中学生进行了描述性和比较性分析。（3）结果：我们发现年龄，年级，父亲的教育程度，周末每天花费的时间，工作日的使用频率，使用目的，恐惧症（NMP）和智能手机成瘾（SA）与低PAP显着相关，而周末的使用频率和互联网访问类型与高PAP密切相关。性别是低，平均和高PAP的重要预测指标。父亲的教育程度和SA也是低和平均PAP的重要预测指标。（4）结论：本研究表明，个人资料，家庭环境，智能手机使用方式，NMP和SA之间的显着关联对菲律宾高中生的PAP产生了重大影响。这表明，应在家庭和学校环境中提供有关使用智能手机的正确指南，以提高人们对SA对学生学习成绩的不利影响的认识。
