Utilizing of the WhatsApp application in recent years, especially in the last ten years, is an increasing use and the way it is exponentially increasing. With the development of mobile phone generations and what the fifth generation technology (5G) is looking forward to, it become necessary to have a mechanism that controls the traffic in the WhatsApp application in the fifth generation technology (5G). In this article, a model called WhatsApp Traffic Control Time-Based (WTCTB) was proposed, which synchronizes with WhatsApp usage times and reduces traffic in secondary-priority applications as well as saving time consumption for traffic flow in addition to saving energy consumption in the phone battery in the sixth generation mobile networks. WhatsApp application is normally consuming more than 40% in almost smart phones of their battery energy, the proposed model WTCTB is reducing this consuming rate to be 35%.
