Recent days, the energy consumption of mobile and tablet devices has become most familiar problem in android operating system. Android is an open source code which is easily understandable and handle by the users to get and use new kind of properties and applications on their handsets. Many studies focused on energy lifetime prediction, but the models are not capable of light weight devices. Energy consumption is becoming an issue in android devices. The peak energy drainer of mobile and tablet devices are the screen, Wi-Fi radios and other transmitter like Bluetooth or GPS. The services of android device includes display brightness, signal weakness, streaming video, playing games, background data, GPS & location services. The proposed system implements the service of streaming video, in which video coder and time slicing approaches are used for reducing the life of energy. The proposed has higher efficiency in improving the life of energy than the existing technique.
