Smartphones continue to reshape our lifestyle and have become an essential part of our daily life, providing people with many services that were not available before on standard mobile phones. The increased features and computing capabilities of Smartphones have allowed them to replace other portable machines, such as laptops, for many users, but particularly for university students. This research paper explores the usage patterns and behaviors among Zayed University students. The main focus of the study is to understand how these smart devices are used as a platform or medium for communication, socialization, learning, entertainment and other activities on campus. A survey was designed and administered to over 400 Zayed University students, and data were collected and analyzed. The findings show that smartphone penetration rate is almost 100 percent (98%) among students, Blackberry and iPhones are the two most common platforms, almost half of the students own and use two Smartphones, and that more than half of the students spend more than five hours per day using these devices, sending and receiving over 30 text messages, using Blackberry messenger and Whatsapp services.
