The usage status, waste electrical and electronic equipment (WEEE) related to the smartphones of on-campus engineering students should be studied. Furthermore, the correlations between their smartphone profiles with energy consumption and environmental knowledge should be understood make measures improve their environmental behaviors.
Pro-environmental behavior and smartphone uses of the on-campus engineering undergraduates in Xi'an, China, were investigated with a self-designed questionnaire anonymously. The energy-saving activities they participated in and their e-waste treatment patterns were analyzed.
Most of the respondents had a smartphone with large screen and high battery capacity, which also had long standby/usage time and frequent charging. Average daily power consumption of one smartphone was estimated to be 6.475 Wh. The surveyed undergraduate students changed their smartphones frequently, which produced large quantities of WEEE annually.
Most on-campus students treated their waste smartphones in the proper ways. However, some of them were short of environmental knowledge about their smartphones. Some measures were suggested to improve their environmental concerns. The findings will help the on-campus engineering undergraduates in China to use their smartphones rationally and to deal with their waste smartphones appropriately.
应该研究校园工科学生使用的智能手机的使用情况和与废弃电子电气设备（WEEE）相关的情况。此外，应该了解他们的智能手机配置与能源消耗和环境知识之间的关系，以便采取措施改善他们的环境行为。
本研究采用自行设计的匿名问卷，对中国西安校园工科本科生的亲环境行为和智能手机使用情况进行了调查。分析了他们参与的节能活动和电子废物处理模式。
大多数受访者都拥有大屏幕和高电池容量的智能手机，待机/使用时间长，充电频繁。估计一部智能手机的日均耗电量为 6.475Wh。被调查的本科生经常更换智能手机，每年产生大量的 WEEE。
大多数在校学生都以适当的方式处理他们的废旧智能手机。然而，他们中的一些人缺乏有关智能手机的环境知识。建议采取一些措施来提高他们的环境意识。研究结果将有助于中国校园工科学生合理使用智能手机，并妥善处理废旧智能手机。
