The purpose of this article is to explore the impact of mobile phone technologies on the Performance Potential of Secondary School Students. The use of modern mobile smart phone technologies has become a symbol of status and strength among students. The mobile phones with the support of internet open to the learners an endless world of information, music, video, fun and other entertainments. As a learning tool the main attraction of mobile phones for learners at secondary school level is not the information aspects but its entertainment and other pleasing features. In these aspects, the nature of this flood of information while using mobile technologies makes young learner a passive mechanic who cannot actively interact with anything in a comprehensive manner. This passiveness and spontaneity in the behaviour of learners slow down their critical thinking ability and thereby it negatively affects performance potential.
