Nokia Siemens Networks Smart Labs and Aalto University in Finland teamed up to investigate how and why video streaming drains smartphone batteries, which is a critical factor in user satisfaction.
Mobile video consumption continues to show huge growth. Sandvine reported that YouTube is the largest source of mobile video traffic in every region examined, accounting for 12- 25% of network data worldwide. YouTube attracts 81.9% of all embedded videos and direct links. Vimeo is a distant second with 8.8%, followed by Dailymotion with 4.0%.
The joint project by Nokia Siemens Networks and Aalto University, which began in early 2012, analyzed the energy consumption of video streaming from these three video channels by smartphones running on Android, iOS, Windows and Symbian operating systems.
Factors affecting energy consumption include the specific video streaming technology in the smartphone, the mobile platform, eg 3G or Wi-Fi, and the method used to access mobile video services, either a native app or a browser, which then loads a Flash or HTML5 player at the beginning of the streaming session.
Based on the initial results from the project, no video streaming technology offers a clear energy advantage in all test situations. The findings also showed the high energy demand of browser players, which consumed twice as much energy as native apps.
The full results of the technical study paper will be presented at the IEEE World of Wireless, Mobile and Multimedia Networks symposium to be held June 4-7, in Madrid, Spain.
The paper will be available for download following the symposium presentation from our Smart Labs homepage.
