At present, mobile phone (MP) and the Internet have become indispensable items in people's daily lives. While smartphones (SPs) bring convenience to people, they also provide opportunities and challenges for ideological and political education (IPE) in colleges and universities (CU). CU are the main development positions of China's socialist higher education. Therefore, it is particularly necessary to strengthen the ideological and moral training and guidance of college students (CS). However, the current complex and changeable social environment and the frequent occurrence of unstable factors have exposed various shortcomings in the traditional way of ideological and political work, putting political educators under tremendous pressure. Therefore, ideological and political educators in CU must conform to the development trend of the Internet in the new era and meet social needs and use advanced scientific and technological means to carry out ideological and political work. This article uses the questionnaire and data analysis methods to better understand the specific situation of CS using smartphones through the questionnaire, so as to explore new educational methods and methods for the construction of IPE in CU. According to the survey results, most respondents use smartphones more often and less use traditional information media. But at the same time, although newspapers and televisions are far behind computers, the Internet, and SP, they still have a certain value in obtaining information. Among contemporary CS, the tools used in the learning process are becoming more and more abundant. Among them, SPs often act as learning tools in students' lives, followed by personal computers, and other methods also play an important role.
